1、有机肥料:结合深耕将有机肥施在根系密集层,可使肥料处于经常湿润的土层中,作到土肥相融,利于根际微生物生长发育和提高土壤酶活性,起到培肥土壤和供给作物整个生育期所需养分的作用。 2、挥发性氮肥:挥发性氮肥如碳酸氢铵浅施易引起氮挥发损失养分,也易引起叶面酌伤,深施可以减少与空气接触,减少挥发。尿素施到土壤转化成挥发性氮肥,也应深施。 1, organic fertilizer: combined with deep plowing of organic fertilizer applied to the dense roots, the fertilizer can be in the often wet soil, soil and fertilizer for the integration, is conducive to rhizosphere microbial growth and improve soil enzyme activity, play a fertile soil And the role of supplying nutrients needed throughout the growing season of the crop. 2, volatile nitrogen: volatile nitrogenous fertilizer such as ammonium bicarbonate caused by easy application of volatile nitrogen nutrients, but also easy to cause foliar injury, deep application can reduce the contact with air and reduce volatilization. Urea applied to the soil into volatile nitrogen fertilizer, should also be applied.
