1.利用垄体深施肥播种机,施肥深度为种下10～15厘米,尿素用量每亩10公斤,氮磷比为1:1。 2.秋深施时间在10月25日以后,秋起垄秋夹肥。春深施采用起垄、深施肥、播种复式作业,或春起垄春夹肥人工点种。因为垄体深松深施肥时垄体中间易架空,播种之后苗带易下陷,造成垄台变垄沟,土温低易粉种,因此应根据土壤墒情适当浅播。
1. The use of ridge deep fertilizer seeder, fertilizer depth of 10 to 15 cm planted, urea dosage of 10 kg per acre, nitrogen and phosphorus ratio of 1: 1. Autumn deep Shi Shi time after October 25, autumn ridge autumn folder fertilizer. Spring deep application of ridge Ridge, deep fertilization, sowing duplex operations, or Spring Ridge spring clip fertilizer artificial point species. Because the ridge deep loose fertilizer deep ridge when the middle of the overhead, seedling easy to sag after sowing, resulting in ridge ditches, low soil temperature easy powder, therefore, should be based on soil moisture appropriate shallow sowing.
