| 摘 要： | 针对目前我国化肥用量激增的现状和农民养分资源投入中存在的问题，在关中平原冬小麦种植区域选取3个区/县进行冬小麦养分资源投入调查分析。结果表明：2009年小麦产量适中的农户占38.3 %；偏低的农户占26.7 %；很低的农户占22.5 %；偏高的农户占11.7 %；很高的农户占0.8 %。冬小麦的纯N平均用量为191.0 kg.hm-2；P2O5平均用量为129.9 kg.hm-2；K2O平均用量为43.8 kg.hm-2。氮肥投入量适中的农户占12.5%；偏低的农户占17.5 %；很低的农户占20 %；偏高的农户占11.7%；很高的农户占38.3%。磷肥投入量适中的农户占8.3%；偏低的农户占37.5 %；很低的农户占19.2 %；偏高的农户占23.3%；很高的农户占11.7%。钾肥投入量适中的农户占6.7%；偏低的占5.0 %；很低的占85.8 %；偏高的占1.7%；很高的占0.8%。养分资源投入以无机为主，有机为辅；投入形式以基施为主。

| Abstract: | According to Status of Chinese farmer chemical fertilizer applying amount increased sharply as well as nutrients resource input problems, winter wheat nutrients resource inputting investigation and analysis were carried out on 3 district and counties of Guanzhong area on 2009. The obtained result showed that: 38.3 percent of winter wheat yield was suitable, 26.7 percent was low, 22.5 percent was the lowest, 11.7 percent was high, 0.8 percent was the highest. Average pure N applying amount of winter wheat was 191.0 kg.hm-2, P2O5 applying amount was129.9 kg.hm-2, K2O was43.8 kg.hm-2. 12.5 percent farmer N applying amount was suitable, 17.5 percent was low, 20.0 percent was the lowest, 11.7 percent was high, 38.3 percent was the highest. For P2O5, 8.3 percent farmer applying amount was suitable, 37.5 percent was low, 19.2 percent was the lowest, 23.3 percent was high, 11.7 percent was the highest. For K2O, 6.7 percent farmer applying amount was suitable, 5.0 percent was low, 85.8 percent was the lowest, 1.7 percent was high, 0.8 percent was the highest. Chemical fertilizer is the main nutrients resource of farmer using for winter wheat, organic manure is the supplementary. Most of fertilizer used as base manure. |
