Radish is a common vegetable. It has a long history of cultivation in China. It can be eaten raw food, especially in the cold winter. Radish is a food with very high edible value. Do you know how white radish is cultivated? Let's introduce Xiaobian to introduce the key points of high-yield cultivation techniques of white radish.
High-yield cultivation techniques of white radish
First, choose the land. It is advisable to plant radishes with more fertilization, less fertilizer, and a large amount of fertilizer left in the soil. It is best to choose melons or legumes and no pesticide residues. It is better to use sandy loam soil with deep, loose, well-drained and relatively fertile soil.
Second, land preparation, fertilization, ridges. Planting autumn radishes must be deep-plowed, and must be broken and finely divided. The fertilization is mainly based on base fertilizer and topdressing. The roots of radish are developed and the base fertilizer needs to be applied. 75 kilograms of ternary compound fertilizer can be applied per mu as base fertilizer. Generally, the width is 1.6-1.7 meters, the depth of the groove is 20-27 centimeters, and the width of the groove is 40-50 cm.
Third, sowing. 1. Sowing period: Generally planted in late July to early August. The varieties are: ivory white, new excellent 1, autumn white 1, west star 3. 2, seeding methods: radish are using live broadcast method, the seeding method is divided into two methods: flat and high ridge, flat hoe is broadcast, high ridge is a hole. The amount of seed used per mu: 0.35-0.5 kg for large-scale seeding, 6-7 for each hole, 0.6-1.2 kg for medium-sized varieties, and 1.8-2 kg for small varieties. The standard for plant spacing is: large The row spacing of the varieties is 50-60 cm, the plant spacing is 25-40 cm, the medium-sized variety is 40-50 cm, the plant spacing is 15-25 cm, the small spacing is about 10-15 cm, and the seeding depth is about 1.5-2 cm.
Fourth, field management. 1, between the seedlings. Generally, when the plants are 1-2 leaves, the first seedlings are carried out, and 3 plants are left in each hole. When the 3-4 leaves are used, the second seedling is carried out, and when 5-6 leaves are fixed, the seedlings are kept, and one hole is left in each hole. 2, watering. Radish is weak in drought resistance, so it is necessary to supply water in a timely manner. Generally, watering should be less in the seedling stage, and irrigation should be stopped before the first half of harvest to improve quality and storage. 3. Scientific topdressing. Radish requires more nitrogen fertilizer in the early stage of growth, which is conducive to promoting vegetative growth; phosphorus and potassium fertilizer should be added in the middle and late stages. For those varieties that have a shorter growth period due to the application of base fertilizer, less topdressing can be applied. 4, cultivating weeding and soil. During the growth of radish, the soil should be ploughed several times as appropriate, especially in the season when weeds grow, and the cultivating and weeding should be carried out. Generally, the cultivating should not be deep, only the topsoil can be loosened, and it is often carried out before the closure.
5. Pest control. 1. Prevention and control of pests. Insects include: aphids, rapeseed, diamondback, and golden worms. Among them, 40% of dimethoate emulsifiable concentrate can be used for the control of locusts, 0.5 kg of water and 500-1000 g of water; 50% of the crystal trichlorfon can be sprayed with 0.5 kg of water and 500 kg of water. 2. Disease prevention and treatment. The diseases of radish are: soft rot, viral disease, downy mildew and the like. Comprehensive prevention and treatment of diseases should be taken to reduce the disease conditions. Seed disinfection can be adopted, rotation can be carried out, deep ditch sorghum, clean field, pest control, etc., if necessary, use chemical control.
Sixth, harvest. When the radish roots of the field are fully inflated, the leaves are lightly colored and yellow, which is the period of harvest. The harvest is too early, affecting the yield, the harvest is too late, 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.
