High-efficiency mulberry sericulture technology and its pest control measures

The mulberry sericulture industry has a long history in China, and the traditional mulberry sericulture is mostly based on the family. This farming method is often small in scale and low in economic benefits. It has certain restrictions on the technical development of mulberry sericulture. Therefore, it is necessary to study advanced science and technology applied to the mulberry sericulture industry, improve the production efficiency and quality of the industry, and make the mulberry sericulture industry continue to develop.

1. Analysis of the main points of mulberry technology

1.1 Planting environment of mulberry

To study the technical points of planting mulberry trees, it is necessary to understand the growth environment of mulberry trees. The growth environment of mulberry can be analyzed from the aspects of soil, temperature and moisture. Soil is the most important part of mulberry cultivation. Under normal circumstances, mulberry can grow normally in the range of 4.5~9, but it grows best in neutral sand. When the temperature reaches 5 °C, the mulberry can breathe effectively. Once it exceeds 12 °C and the water is sufficient, the mulberry can germinate even in winter. And 25~30 °C is the fastest temperature for mulberry growth. Mulberry is a deep-rooted plant. If the water is too much, the mulberry tree will die. The water content of the mulberry tree is generally 60%. The mulberry leaves with high water content are not good for sericulture. Therefore, when selecting the planting environment of mulberry trees, the soil is preferably neutral sand, and the sun is abundant. The temperature is above 5 °C, preferably at 20 °C, the humidity is suitable, the water is sufficient, but the groundwater level should be lower than 1 m above the ground. Hereinafter, such an environment is the most suitable growth environment for mulberry trees.

1.2 Planting of mulberry trees

Mulberry can be planted all year round, but it is usually planted in winter and spring in China. It is planted in a single row with a row spacing of 1.8~2 feet and a plant spacing of 0.3~0.4 feet. The mulberry trees planted in a single row are more advantageous for weeding and fertilization, and are preferably east-west and easy to collect.

In the planting process of mulberry trees, we must pay attention to the management of fertilization, ensure that the nutrients of nitrogen, phosphorus and potassium required for the growth of mulberry trees are fully supplied. At the same time, organic fertilizer should be applied more. The organic fertilizer is not only green and pollution-free but also capable of improving the soil. In the fertilization of mulberry trees, the method of open-hole fertilization should be adopted, and fertilization should be carried out 20 cm away from the roots of mulberry trees. At the same time, the fertilization of mulberry trees in one year is divided into spring fertilizer, summer fertilizer and winter fertilizer. In the spring and summer fertilization, the compound fertilizer is applied mainly with NPK. In the summer and winter, organic fertilizer should be applied, and at the same time, it should be combined with irrigation when fertilizing.

For the irrigation of mulberry trees, spring irrigation is carried out every spring, and winter irrigation is carried out every winter from late November to early December. The mulberry tree needs to be irrigated once every 10 days during the development period, while it is relatively less during the harvest period and once every 15 days.

1.3 Use of planting machinery and equipment

In order to improve the efficiency of mulberry planting and reduce manual work, the mechanization of mulberry planting should be improved. The improvement of mechanization can also make China's sericulture industry more industrialized and scaled. The most commonly used machinery in the mulberry planting process is a ridger, a rotary tiller and an electric spray and a cutting machine. The ridger is equipped with ploughs for arable land on both sides and in the middle, which improves the efficiency and quality of mulberry gardening. Rotary tillers are mainly used for weeding and fertilization in mulberry fields. Electric spray improves the effectiveness and quality of the spray compared to hand-held and motorized sprayers. The cutting machine is used for the trimming of mulberry branches, and the cross section of the trimmed trimmer is smoother and more complete. All in all, the application of mechanical equipment in mulberry gardens can improve the efficiency and quality of mulberry planting, and it can free people from heavy labor, reduce labor costs, and improve the management efficiency of mulberry gardens.

2.1 Optimization of silkworm varieties

Choosing high-quality silkworm varieties is an important condition for silkworm breeding. When selecting mulberry varieties, it is necessary to comprehensively consider the geographical environment, temperature and other conditions of the farming area. For example, for aquaculture gardens in mountainous areas, some varieties with strong adaptability and strong resistance should be selected to adapt to the conditions of mountainous areas; for areas with better humidity and temperature, there is no need for excessive silkworms. Variety is required. At the same time, after selecting the appropriate silkworm varieties, we must also pay attention to the varieties of mulberry leaves. The quality of mulberry leaves directly determines whether silkworms can grow healthily. The poor quality of mulberry leaves will cause the growth of silkworms to be slow, and it is prone to disease and even death. Therefore, when it comes to silkworm breeding, choosing the right silkworm is the first thing to do.

2.2 Supplementary reminder

The day before the silkworm species reached the small silkworm, the room temperature was adjusted to 24 ° C, and the difference between dry and wet was 2 ° C. When the silkworms reach the co-culture room, the temperature is raised to 25.5 ° C, the difference between dry and wet is 1.5 ° C, and the shading protection is performed. After the silkworm enters the co-education room, it will ovulate. In the process of replenishing the green, the window should be ventilated every time to prevent gas poisoning. After 1~2 days of supplementation, the silkworm eggs are 80. More than % has been hatched, and the next step is to collect ants. If there are unhatched silkworms after receiving the ants, it is necessary to continue to make up the green, and try to make a batch of silkworms to complete the ants twice.

2.3 Silkworm breeding

For the breeding of silkworms, the small silkworms and the large silkworms are described separately. For the breeding of small silkworms, the most important thing is to control the phenomenon of breeding. In general, for the silkworms of 1~3 years old, it is necessary to carry out the breeding technology, which can not only increase the number of small silkworms, but also make the silkworms healthier. Can reduce the amount of mulberry leaves. The small silkworm stage is the most important growth stage of silkworm. If the small silkworm stage can be cultured well, the small silkworm's physical condition will be improved and the disease resistance will be enhanced, which will lay a good foundation for the cultivation of large silkworm.

For the breeding of large silkworms, analysis should be given from temperature and humidity, ventilation, mulberry leaves and so on. Firstly, it is lower than the breeding temperature of the large silkworm. The temperature of the 4~5-year old silkworm should be 23~25°C, and the dry-wet difference is 3~4°C. Therefore, for low temperature rainy days and high temperature dry days, artificial temperature and humidity adjustment should be carried out to ensure that temperature and humidity are always suitable for the growth of large silkworms. Secondly, as the saying goes, the large silkworms are raised by the wind. Therefore, when the large silkworm breeding is carried out, the window should be opened and the ventilation of the silkworm chamber should be strengthened. However, when the temperature is low at night, the doors and windows should be closed in time to avoid the loss of appetite of the silkworm due to low temperature. In turn, it affects the body quality of silkworms and ultimately affects the quality and yield of silkworms. Third, when carrying out large silkworm breeding, pay attention to keeping the silkworms moderately dense. If the number of silkworms is too small, it is easy to form foot leaves, which will cause waste of mulberry leaves. On the contrary, it will cause silkworms to climb silkworms, causing silkworms. The trauma, increase the infection rate. Fourth, high-quality mulberry leaves are also the key to large silkworm rearing. The mulberry leaves in the large silkworm period require high maturity and no insects, etc., and the mulberry leaves should not be stored for more than 12 hours, and fed three times a day. Finally, there is a preferred method for large silkworm breeding, the large silkworm ground strip mulberry breeding method, that is, the cultivation of continuous branches and leaves. This farming method was originally started in Japan and is now widely used in China. The method is convenient to operate and saves labor costs.

2.4 picks

The time of picking should be determined according to the change of the body shape of the silkworm. After the knot is completed, the silkworm will be molted and the skin color of the carcass will turn deep. When turning yellow, it is most suitable for picking. Under normal circumstances, the spring silkworm period is picked within 6~7 days after the upper scorpion, the summer and autumn silkworms are 5~6 days, and the late autumn silkworms are 7~8 days. The picking time has a great influence on the quality of cockroaches. The true quality of the upper jaw, the ochre, the thickness of the enamel layer and the shrinkage can not be flawed.

2.5 Prevention and control of pests and diseases

A variety of pests and diseases will occur during the breeding of silkworms, and the prevention and control of pests and diseases needs to be done. First, the diseases of silkworms can be divided into infectious and non-infectious. Infectious pests and diseases are generally viral or fungal, such as the more common pus, which is characterized by short and high knots in the silkworm, and this kind of pests and diseases can cause the silkworms to be crusted, which is very common for silkworm breeding. Adverse. Most of the non-infectious silkworm disease is due to parasites in the silkworm.

Because silkworms have more pests and diseases during the breeding process, and once the disease occurs, the possibility of cure is relatively low, and it is easy to expand. Therefore, in the process of breeding silkworms, prevention and treatment is still the main. The first is to disinfect and prevent disease. The silkworm chamber should be cleaned and disinfected one week before the silkworm rearing. At the same time, the leaf chamber and the surrounding environment should be cleaned up. For the disinfection of the silkworm chamber, a sodium hypochlorite disinfectant with a concentration of 0.4% in the sodium hypochlorite stock solution is used to spray or spray all the equipment in the silkworm chamber. The appliance can also be directly immersed in the disinfectant for disinfection. At the same time, wash hands and change shoes when carrying out the Jamsil. Prevent the introduction of viruses and bacteria into the soles and affect the growth of silkworms.

3. Conclusion

The mulberry sericulture technology is very important for the development of silk in China. This article describes the cultivation of mulberry trees and the cultivation of silkworms. For the cultivation of mulberry trees, it is necessary to start from the selection of suitable planting areas, and scientific management should be carried out for the planting season, fertilization and irrigation. For the breeding of silkworms, we must first select the appropriate silkworm species, and pay attention to the growth characteristics of small silkworms and large silkworms when they are cultured, adopt appropriate breeding methods, and pay attention to the prevention and control of pests and diseases during the breeding period.

With the continuous development of China's social economy, the mulberry sericulture industry is also constantly developing and progressing, and has achieved some results, making it possible for China's mulberry sericulture industry to achieve industrialization and scale. In the future mulberry sericulture industry, it is still necessary to continuously improve equipment and technology. Especially in the field of artificial breeding, it is necessary to continuously improve and develop, so that the mulberry sericulture industry in China has been continuously developed.
