- 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 1 112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 fer-tilizer and the other trace element fertilizer.This research directs towards the balance fertilizer test.The result of white serumearth test in Huachuan county indicated that the limited factors of paddy output mainly were nitrogen and zinc, secondlywere phosphorus and potassium, andboron was the potential factor.It resulted in a reduction in the paddy output by 11.5%and 8.7%without nitrogenous fertilizer and zinc fertilizer;7.4% and 5.7% without phosphate fertilizer and potash fertiliz-er;4.7% without boric fertilizer;35.9% without any fertilizer;and 9.5% in peasants’ habitual way of fertilization thanOPT.It resultedin a reductionin the income by 1 011yuan per hectare and 1112 yuanper hectare without nitrogenous fertil-izer and zinc fertilizer;737 yuan per hectare and 544 yuan per hectare without phosphate fertilizer and potash fertilizer;584yuan per hectare without boric fertilizer.
