1994~1997年在全疆11个县(市、团场)进行的棉花、玉米、甜菜三种主要作物专用肥的示范试验结果表明,与常规施肥相比,棉花增产8.4%~21.4%,增产幅度南疆高于北疆。玉米增产11.6%~28.5%,正播玉米增产幅度高于复(套)播。甜菜增产7.9%~19.4%,含糖率增加0.4~2.4个百分点。专用肥能提高肥料利用率,具有增产增效作用。
The results of the demonstration experiment on the special fertilizers for three main crops of cotton, corn and sugar beet from 11 counties (cities and farms) in Xinjiang from 1994 to 1997 showed that the yield of cotton increased 8.4% ~ 21 compared with the conventional fertilization. 4%, South Xinjiang higher than the northern margin. Maize yield 11.6% ~ 28.5%, Sowing corn yield increase higher than the complex (sets) broadcast. Beet yield increased by 7.9% ~ 19.4%, sugar content increased 0.4 ~ 2.4 percentage points. Special fertilizer can improve fertilizer utilization, with the effect of increasing production and efficiency.
