摘要
[目的]为六安市裕安区徐集镇提供小麦最佳施肥方案。[方法]以扬辐麦2号为材料,采用"3414"最优回归设计研究不同施肥方案对小麦产量和经济效益等的影响。[结果]235 kg尿素+500 kg过磷酸钙+157.5 kg氯化钾做基肥、116.3 kg尿素做苗肥、40 kg尿素+105 kg氯化钾做拔节肥的处理,小麦产量最高,为6 301.5 kg/hm2;235 kg尿素+500 kg过磷酸钙+105 kg氯化钾做基肥、116.3 kg尿素做苗肥、40 kg尿素+70 kg氯化钾做拔节肥的处理,纯收入最高,为8 071.2元/hm2。根据试验结果建立了肥料效应函数方程,由此方程得出氮、磷、钾最佳用量为:N 157.35、P2O574.70、K2O 97.20 kg/hm2,产量可达6 135.90 kg/hm2。结合当地生产实际,氮、磷、钾提倡用量分别为165.0、75.0、105.0kg/hm2。[结论]试验确定了安徽六安市裕安区徐集镇小麦施肥的最佳方案。
[ Objective ] The study was to provide the optimum fertilizing scheme for wheat in Xuji Town in Yuan District in Liuan City. [ Method] With Yangfumai 2 as the material, the best regression design ＂3414＂ was taken to study the effects of different fertilizing scheme on yield and economic benefit of wheat. [ Result] The wheat yield in the treatment with 235 kg urea ＋ 500 kg superphosphate ＋ 157.5 kg potassium chloride as the base fertilizer, 116.3 kg urea as the seedling fertilizer, 40 kg urea ＋ 105 kg potassium chlorideas as the jointing fertilizer was the highest, being 6 301.5 kg/hm^2. The pure income in the treatment with 235 kg urea ＋ 500 kg superphosphate ＋ 105 kg potassium chloride as the base fertilizer, 116.3 kg urea as the seedling fertilizer, 40 kg urea ＋ 70 kg potassium chloride as the jointing fertilizer was the highest, being 8 071.2 yuan/hm^2. According to test result, the functional equation on fertilizer effect was established, from which the optimum amount of N, P and K educed as 157.35,74.70, 97.20 kg/hm^2 resp. , then the wheat yield could reach 6 135.90 kg/hm^2. According to the local production practice, the recommended amount of N, P , K was 165.0, 75. 0, 105.0 kg/hm^2 resp.. [ Conclusion ] The test determined the optimum fertilizing scheme for the wheat in Xuji Town in Yuan District in Liuan City of Anhui Province.
