Radish planting technique sowing time and field management method

Although radish is a kind of vegetable, the chance of eating it is not very big, and the taste of radish is very common, but in addition to fried, radish can also be stewed and served or marinated. The vegetables are eaten, so that the sales of radishes are not limited.

Radish scientific planting technology

1. Site preparation: radish cultivation should not be continuous with cruciferous vegetables, deep ploughing and turning, while applying base fertilizer, applying 370 to 45,000 kilograms of decomposed organic fertilizer per hectare, 1200 kg of plant ash, 375-450 kg of superphosphate, and diammonium phosphate 750 kg.
2. Sowing at the right time: The radish sowing period is determined by the variety characteristics and market needs. The suitable sowing season for autumn and winter radish is from late July to early August. Spring radish can be sown from late February to early April. The seeding rate varies depending on the cultivation density. , generally 3 to 6 kg / ha.
3. And time seedlings: radish planting is generally carried out in the first time when the first true leaf is unfolded, and when the big broken belly is selected, a strong seedling with the characteristics of this variety is selected, and other weak plants can be dropped.
4. Reasonable watering: the soil moisture content of radish is more than 90% during germination, the soil moisture content is preferably 60% at seedling stage, the water demand in the leaf growth period is more, the soil moisture in the root growth period is 70-80%, and the root growth is still in the late stage. Water should be properly watered to prevent hollowness.

Variety of radish

1. Autumn and winter radish type: China's general cultivation type. Sowing in late summer and early autumn, harvesting in late autumn and early winter, the growth period is 60-100 days. According to skin color and use, it can be divided into different varieties such as red skin, green, white skin and green skin red heart. The representative variety is Xue Chengchang.

3. Spring and summer radish type: widely cultivated in China. It is more cold-tolerant, stronger in winter, shorter in growth period, generally 45-60 days, and it is easy to convulsion in the sowing period or improper cultivation management. Representative varieties include Beijing Cannon Tube, Penglai Spring Radish, and Nanjing May Red.
4. Summer and autumn radish type: cultivated in the south of the Yellow River Basin in China, often used as a summer and autumn off-season vegetables.

The four seasons of radish cultivated in China include Nanjing Yanghua Radish, Shanghai Small Carrot, Yantai Red Ding and so on.

Radish harvesting technology

First, the harvesting standard

1. The color of the leaves turns light, and the underground stems are fully inflated and harvested in time;

2, requires a uniform head, no roots, no mud, no tillers, no deformities, no heart, no wounds, no gray heart;

3, according to the consumption market in different regions, the requirements for the size of radish are different, and the harvesting standards are also different. Some areas require more than two kilograms of radish, and some areas require less than two kilograms of radish, so it is necessary to determine the harvest according to market needs. The size of the standard.

Second, pre-cooling transportation: pre-cooling into the cold storage (2-4 °C) for about 10 hours, loading and transportation of insulation and listing.

Radish storage method

1. Soil pit storage method: Cut the fresh radish to the top, remove the hair root, and strictly remove the radish with insect damage, mechanical injury, crack and too small. Dig a pit of 1 meter square, put the radish roots up, top down, leaning against the pit wall, in order. Code a layer of radish, sprinkle a layer of pure soil about 10 cm thick, so alternately placed, a total of four layers. If the pit soil is too dry, it can be sprayed with water and wet. After the last layer of code is good, it is necessary to gradually thicken the soil layer according to the climate change, and the sky is warm and less covered with soil, and the soil is covered with strong cold current. The soil is covered before and after the cold, and the soil thickness is 1 meter. Good quality radishes are not exposed to heat before entering the pit. They are not frozen after entering the pit and can be stored in early March.

2, mud storage method: the radish is topped, put in a yellow mud and roll a circle, so that the radish is a layer of mud shell, stacked in a cool place. If you plant a layer of wet soil outside the radish pile, the effect is better. Storage method outside the water tank: put a water tank inside, fill it with water, put the radish around the cylinder, and then pour 15 cm thick wet soil.

In the face of good market sales, planting radish is also a rich project, although the market price of radish is not high, but once the radish is reached to a certain scale, and the yield and quality of radish are reliable, the radish can bring The benefits are also very substantial.
