| 摘 要： | 针对桦川农民施肥中存在重氮肥,轻磷、钾肥及其它中微量元素的现象,开展水稻平衡施肥的研究。试验结果表明：桦川县白浆土试验水稻产量限制因子主要是氮和锌,其次是磷和钾,硼为潜在限制因子。不施氮肥、锌肥分别减产11.5%和8.7%;不施磷肥和钾肥分别减产7.4%和5.7%;不施硼肥减产4.7%;不施肥减产35.9%,农民习惯施肥较OPT减产9.5%。不施氮肥减少收入1011元.hm-2,不施磷肥减少收入737元.hm-2,不施钾肥减少收入544元.hm-2,不施锌肥减少收入1112元.hm-2,不施硼肥减少收入584元.hm-2。

| Abstract: | The peasants from Huachuan prefer to fertilizing more nitrogenous fertilizer to phosphate fertilizer and potash fertilizer and the other trace element fertilizer.This research directs towards the balance fertilizer test.The result of white serum earth test in Huachuan county indicated that the limited factors of paddy output mainly were nitrogen and zinc,secondly were phosphorus and potassium,and boron was the potential factor.It resulted in a reduction in the paddy output by 11.5% and 8.7% without nitrogen... |
