冬季播种绿肥时,以红花草子为主,适当混播满园花、麦类、蚕豆、油菜等作物,可比单播红花草子增产2—4成,并且比单播可增加五氧化二磷32%,增加氧化钾49%,平衡了绿肥的氮、磷、钾的比例。混播绿肥翻沃后栽插早稻,禾苗前期返青早,分蘖快,后期不早衰,落色好。绿肥混播还可减少红花草子三分之一的用种量,这样可保证或扩大绿肥播种面积。绿肥混播技术:1.混播方式各种绿肥混播均应以草子类豆科绿肥为主,适当搭配其他绿肥品种。①双季晚稻田可以红花草子为主,混播油菜(或满园花)与大麦。②中稻田翻耕后混播,可用红花草
When sowing green manure in winter, safflower and grass seeds are mainly used, and crops such as garden flowers, wheat, broad beans and rapeseed are mixed appropriately, yielding 2-4% more than monoclafts, and increasing phosphorus pentoxide 32 than unicasting %, Increase 49% of potassium oxide, balanced green manure nitrogen, phosphorus, potassium ratio. Green mixed fertilizers after transplanting early rice, early seedling early greening, tillering fast, the late premature aging, falling color good. Mixed green manure can also reduce the Safflower one-third of the seeds, so as to ensure or expand the sown area of green manure. Mixed technology of green manure: 1. Mixed sowing variety of green manure mixed sowing legumes should be based mainly grass green, appropriate with other green manure varieties. ① double season late rice can be mainly safflower, mixed rape (or garden flowers) and barley. ② mid-tillage mixed plowing, available safflower grass
