黑土中大豆连作障碍诊断系统的建立初报——主要障碍因子的确立
Establishment for the Diagnosis System of Soybean Continuous Cropping in Black Soil of Main Inhibitors
【摘要】 黑龙江省黑土区大豆种植连作现象严重,造成生长不利、产量降低,初步诊断主要障碍因子是孢囊线虫增加,根腐病加剧,土壤中大、中、微量元素含量不平衡。另外,农民施肥不科学也是影响大豆产量的一个主要因素。为此,建立了大豆连作障碍诊断系统,找出了主要障碍因子。
【Abstract】 The phenomenon that the soybean has been cultivated continuously in the same field for many years is more and more seriously, it courses many inhibitors for the soybean’s growth and yield,for example, increasing of cyst nematode, aggravating of root rot, unbalancing of macro- and micro-elements, and it is a main disadvantageous factor that farmers apply fertilizer unscientifically.
