湖州地区东部属滨湖水网平原,地势低洼,种植作物以麦稻稻三熟轮作制为主。近年来,大气层元素结构改变,气候失调,自然灾害频繁发生,造成“渍害、高温强光、病虫害”对作物的侵袭危害,除了采取农艺综合措施外,施肥上要氮磷钾合理配施,提高作物秸秆中的N、P_2O_5、K_2O含量,增强作物机体的抗逆性能,改善作物的经济性状,从而提高籽粒产量。 The eastern part of Huzhou is a lake-water plain, with low-lying land. The crops are mainly planted with three-cropping system of wheat and rice. In recent years, the atmospheric element structure changes, climate disorders, natural disasters occur frequently, resulting in “stains, high temperature glare, pests and diseases,” the invasion of the crop damage, in addition to the agronomic comprehensive measures, the fertilization of nitrogen, phosphorus and potassium reasonable allocation, Improve the N, P_2O_5, K_2O content in crop stalks, enhance the stress resistance of crops, improve the economic traits of crops, and increase the grain yield.
