Radish is a common vegetable. It has a long history of cultivation in China. It can be eaten raw or cooked. Especially in cold winter, radish is a food of great edible value. Do you know how white radish is cultivated? Now let Xiaobian introduce the key points of High-yield Cultivation Techniques of white radish.

High yield cultivation techniques of white radish

1.Choose a place. For radish planting,trim tray pollen it is better to choose the former crop with more fertilization, less fertilizer consumption and a large amount of fertilizer left in the soil. It is best to choose the land plot with melon or bean stubble and no pesticide residue. It is better to use the deep, loose, well drained and fertile sandy loam.

2.Land preparation, fertilization and ridging. Autumn radish must be cultivated deeply, broken and raked carefully. The fertilization is mainly based on base fertilizer, supplemented by topdressing. The radish root system is developed, and enough base fertilizer needs to be ...
... applied. 75 kg ternary compound fertilizer can be applied per mu as base fertilizer. The general border width is 1.6-1.7m, the ditch depth is 20-27cm, and the ditch width is 40-50cm.

3.Sow. 1. Sowing date: generally from late July to early August. Varieties: ivory white, Xinyou No. 1, Qiubai No. 1 and Xixing No. 3. 2. Sowing method: radish adopts direct seeding method. The sowing method is divided into flat border and high ridge. The flat border is sowing and the high ridge is hole sowing. Seed consumption per mu: large varieties need 0.35-0.5kg for hole sowing, 6-7 seeds for spot sowing, medium varieties need 0.6-1.2kg for strip sowing, and small varieties need 1.8-2kg for spreading. The general standard of row spacing is: row spacing of large varieties is 50-60cm, row spacing of 25-40cm, row spacing of medium varieties is 40-50cm, row spacing of 15-25cm, and small spacing of about 10-15cm; The sowing depth is about 1.5-2 cm.

4.Field management. 1. Intermediate seedling. Generally, the first thinning is carried out when the plant has 1-2 leaves, with 3 plants in each hole, the second thinning is carried out when it has 3-4 leaves, and the seedling is fixed when it has 5-6 leaves, with 1 plant in each hole. 2. Water. The drought resistance of radish is weak, so it is necessary to supply water in time. Generally, less water should be irrigated during the seedling stage, and irrigation should be stopped half a month before harvest, so as to improve quality and storage resistance. 3. Scientific topdressing. Radish needs more nitrogen fertilizer in the early stage of growth, which is conducive to promoting nutritional growth; The application of phosphorus and potassium fertilizer should be increased in the middle and late stage. For varieties with short growth period and sufficient base fertilizer, less topdressing can be applied. 4. Intercropping, weeding and soil cultivation. During the growth period of radish, it is necessary to plough and loosen the soil several times as appropriate, especially in the season when weeds breed. Generally, it is not suitable to plough deeply, only loosen the topsoil, and carry out it mostly before closing the row.

5.Pest control. 1. Pest control. Pests include aphids, vegetable borers, vegetable moths and golden needles. trim bin trayAmong them, the control of aphids can use 40% dimethoate EC 0.5kg and water 500-1000g; The control of the rice stem pest is 90% crystal, 0.5 kg and 500 kg. 2. Disease control. Radish diseases include soft rot, virus disease, downy mildew and so on. Comprehensive prevention and control of diseases shall be adopted to reduce the disease conditions. Seed disinfection, rotation, deep ditch and high border, keeping the field clean, preventing and controlling pests, etc. can be adopted, and chemicals can be used for prevention and control when necessary.

6.Harvest. When the fleshy roots of radish in the field are fully expanded and the leaf color turns light yellow, it is the appropriate harvest period. The harvest is too early, which affects the yield. The harvest is too late, which is easy to age, hollow and poor quality. After the fleshy root is fully expanded, it should be harvested in time, and the yield is the highest at this time.
