Planting pickled mustard tuber in winter, mastering skills for high yield

1. Variety selection. The local farm family shrinks the head species, Yu shrinks No. 1 and other varieties.

2. Cultivate strong seedlings. Sowing at the end of September and the beginning of October, the sowing amount per mu was about 0.4kg, leaving enough according to the ratio of seedlings to seedlings at 1:10. Control aphids and Bemisia Tabaci with corresponding pesticides. Go to the field with fertilizer, medicine and soil before transplanting.

3. Apply sufficient base fertilizer. The rotten organic fertilizer 2000~2500kg was applied per mu before ploughing, and the compound fertilizer (15m / m 15 / mu) 30kg was applied during soil preparation.

4. Reasonable close planting. Generally, it can be transplanted in the first and middle November and the seedling age is about 35 days. There are about 20 000 plants per mu in the coastal plain and 1 ~ 15000 plants per mu in the plain rice area.

5. Rational fertilization. On the basis of applying sufficient base fertilizer, topdressing is generally applied four times. Application of seedling fertilizer after planting or returning seedlings, urea 4kg / mu, ammonium bicarbonate 25kg + calcium superphosphate 20kg + potassium chloride 5kg / mu in late January, heavy fertilizer in late February, urea 25kg + potassium chloride 12.5kg / mu, and appropriate amount to promote balance according to field growth.

6. Water management. In winter and spring, the ditches should be cleaned in time to prevent stagnant water in the field, reduce the humidity in the field, and prevent root waterlogging and diseases. When there is a long-term drought after planting, furrow irrigation and irrigation can be used to resist drought and promote the return of seedlings.

7. Disease and Cordyceps control. Mainly prevent virus disease, black spot, white rust, aphids and so on. Agents can choose Ningnanmycin, chlorothalonil, enantiomide, acetamiprid and so on. Alachlor and Metolachlor are generally selected to control weeds 1-3 days before transplanting.

8. Harvest at the right time. The harvest usually begins at the beginning of April and ends around April 15.
