Citron is a popular wild vegetable variety in recent years. Nowadays, it is widely cultivated in many areas of China. In many areas, cultivation by camphor has become a way for local villagers to get rich. Today, let's learn to learn the ecological cultivation techniques of camphor. First, plant management The colonization time is best chosen in the late fall and early winter. Because the temperature has dropped during this time, but the ground temperature has not dropped, there is enough slow seedling time before winter, which can promote the early germination of the seedlings and the rapid growth. In addition, it can also be planted before germination in early spring. Planting plots require thick soil layers, loose soil, convenient irrigation, and convenient drainage. Before planting, the soil should be deep-turned, and the irrigation and drainage channels should be repaired. The base fertilizer should be 5,000-7,000 kilograms of organic fertilizer per mu. Citron is a deep-rooted tree with obvious main roots and fine lateral roots. It is advisable to choose 2~3 year old seedlings to minimize the effect of lateral root fracture on the survival rate. If the main root is too long, it can be properly trimmed, but the root should be kept as much as possible. The planting depth should be flat or slightly deeper than the original soil mark, ensuring that the roots are not stretched. After transplanting, the root water should be poured. After the water seeps, the soil is covered with mounds to ensure the survival rate. The young tree can be sprayed with a new high-fat film, which is good for keeping warm and moisturizing, isolating pests and diseases, and shortening the time for slowing down the seedlings. In addition to high-density planting in greenhouses, camphor can also be cultivated in common cultivation and dwarf planting. Ordinary large-scale cultivation of camphor forest, plant spacing is 5 m × 7 m, the management method is similar to traditional sporadic planting; dwarf dense planting, the general plant spacing is 40 cm × 50 cm, planting 3000 plants per acre. The latter has become more popular in recent years, with convenient picking and higher yields. Second, the initial pruning The pruning of the early stage of the cultivation of the toon is mainly based on the shape, and it differs depending on the cultivation method. Ordinary cultivation of camphor is more flexible, which can achieve the purpose of tall trunk, good ventilation and lighting, large harvesting surface and stable yield. The camphor tree cultivated in dwarf and densely planted adopts methods such as topping, short cutting, flat cutting and ring stripping to promote its dwarfing and promote its multiple branches to increase yield. In addition, in the early stage of the growth of the camphor, it is necessary to remove the sprouts in time to avoid nutrient loss. The dwarf fragrant tree has two layers and a cluster. The former is to go to the top of the seedling at 2 meters high to promote the lateral buds to form three layers of backbone branches: the first layer is 70 cm high, the first layer to the second layer is 60 cm apart, and the second to third layer spacing is 40. cm. The overall shape of the tree is high, the lignification is sufficient, and the yield is relatively stable. The latter is to remove the top of the shoot when the height of the seedling is 1 meter, leaving new branches, picking young leaves, not picking the top buds, and the branches are 20 to 30 cm long and then wiped the head. This tree is generally short and has a main branch that is good for picking. Third, water and fertilizer management Toona sinensis is a fast-growing tree species in the early stage and has strong adaptability to soil. The field management of common camphor cultivation is relatively extensive, but in the case of intensive planting, in order to ensure the growth rate and yield, it is necessary to pay attention to the management of fertilizer and water. Toon is wet and not tolerant to drought. It can be watered once a month or so. When it is dry, it should be poured more properly to keep the soil moist. When there is too much water, it is necessary to drain and cultivate in time, weeding and loosening the soil to prevent surface compaction and water accumulation. Topdressing should be carried out in April-May and July, and 1000-1500 kg of farmyard manure per acre can be applied. Fourth, wintering and freezing The citron is warm and cold-resistant. It can be cultivated in most areas of southern and northern China, but newly planted young plants may freeze to death below -10 °C. Therefore, in the cold regions of the north, anti-freezing measures should be taken for newly planted young plants to ensure germination and growth in the coming year. In autumn, water control and fertilizer control can be carried out on seedlings to curb the growth of young plants and accelerate their lignification, thereby enhancing their ability to resist cold. After the planting, the next year or 2 years old seedlings can be wrapped with fine straw before the freezing, or tied with a straw rope. Before the soil is frozen, the diluted manure water can be poured to increase the salt content of the soil solution to reduce the freezing temperature of the soil and reduce the probability of freezing the seedlings. V. Pest Control Toona sinensis disease is more common with leaf rust and powdery mildew, mainly affecting leaves and shoots. Control measures: Spray 0.3 Bomei stone sulphur mixture before germination, spray once every 15 days, each time 100 kg per acre; spray 10% difenoconazole water dispersing granules 3000-6000 times solution at the time of onset In winter, the diseased branches and diseased leaves are removed and burned intensively; it is not suitable for planting too densely. Do not apply excessive nitrogen fertilizer, pay attention to the application of nitrogen, phosphorus and potassium fertilizers. Toona sinensis pests are mainly leafhopper pests such as spotted wax mites. Control measures: the initial larvae can be sprayed with 5% imidacloprid EC from 2000 to 3000 times; when it is harmful, it can be sprayed with 5% emamectin benzoate microemulsion 3000-5000 times solution, which can cure jaundice; winter When trimming, scrape off its egg mass. Six, axillary bud picking In the autumn, the aromas can be picked in the second year. In the first 3 years, only one harvest is taken each year. It is advisable to pick the top buds, promote the side branches, and cultivate the tree shape. After 3 years, the crown has been shaped, and it can be harvested 2 to 3 times. The top and side buds can be harvested. If the management is in place, the harvest period can be harvested once every 20 days or so, and 6 to 10 times in one year. When picking, it can be cut with scissors, and it is forbidden to pull the hard hoe by hand, so as not to damage the branches and bark. The above is all the key points of the ecological scale planting technology of the camphor. Let's take a look at this technology is not suitable for you. Of course, the specific planting technology should be considered according to the actual situation. Do not say anything online, what do you do.
