High-yield technology of direct seeding rapeseed in rice field

Direct seeding cultivation in rice fields refers to the cultivation method of directly planting rapeseed seeds in the field after harvesting of medium rice. The live rapeseed is more labor-saving, time-saving and cost-effective, and it is an agricultural practical technology worthy of promotion. Its main technical points:

 

　　 1 , variety selection. Early-maturing hybrid rapeseed varieties with short growth period, lodging resistance, strong disease resistance, short plant height and excellent quality were selected. Such as 沣 730 , Xiangzao 631 and so on.

 

　　 2 , before and after preparation. Previous Crops should be selected season paddy harvest time not later than around October 20. The requirements for harvesting are to cut the rice and keep the short rice piles at a height of about 10 cm. Easy to seed operation.

 

　　 3 , trenching and land preparation. Use the rotary tiller to plow the fields and open the trenches and trenches.

 

　　 4 , apply enough base fertilizer. Before the rotary tiller plows the field, apply 40 kg of 51% compound fertilizer per acre . Another 1 kg of boron fertilizer was added as the base fertilizer. Prevent rapeseed from “flowers and not real”. Note that the seeds must not be in direct contact with the fertilizer, otherwise the seeds will not germinate and affect the emergence of the seedlings.

 

　　 5 , timely delivery. Distribute rapeseed from 300 to 400 grams per acre .

 

　　 6 , and time seedlings, set seedlings.

 

　　 7. Do a good job in chemical weeding and control of grass damage. In the 6 to 8 leaf stage of rapeseed , evenly spray 30 ml of water with oil (thaloxime) 30 kg per acre .

 

　　 8. Pay attention to the prevention and control of pests and diseases and harvest in time.
