| 摘 要： | 研究测土配方施肥对玉米生长性状、产量、经济效益和养分利用率的影响,进而指导阿克苏市玉米科学合理施肥,提高化肥利用率,减少化肥投入,实现玉米化肥减量增效的目标。以金谷玉6号玉米为试验材料,设置不施肥(CK)、无氮(PK)、无磷(NK)、无钾(NP)和氮磷钾(NPK)5个处理,在收获期对玉米株高、径粗、穗长、穗粒数、百粒重、产量、平均产值、净收入和养分利用率等指标进行测定。实验结果表明:全年施肥量为尿素29.78kg/667m2,重过磷酸钙25kg/667m2,硫酸钾10.4kg/667m2,对玉米的生长、产量和经济效益均有促进作用。玉米氮肥的利用率为36.26%,磷肥的利用率为17.39%,钾肥的利用率为41.99%。

| Abstract: | The effects of soil testing and formula fertilization on the growth characters, yield, economic benefit and nutrient utilization rate of corn were studied, so as to guide the scientific and rational fertilization of corn in Aksu City, improve the utilization rate of fertilizer, reduce fertilizer input, and achieve the goal of reducing the amount and increasing the efficiency of corn fertilizer. Five treatments, no fertilization (CK), no nitrogen (PK), no phosphorus (NK), no potassium (NP) and no nitrogen, phosphorus and potassium (NPK), were used to determine plant height, diameter, ear length, kernel number per ear, 100 kernel weight, yield, average output value, net income and nutrient utilization rate of maize at harvest stage. The results showed that urea 29.78kg/667m2, heavy superphosphate 25kg/667m2 and potassium sulfate 10.4kg/667m2 could promote the growth, yield and economic benefit of maize. The utilization rate of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer was 36.26%, 17.39% and 41.99% respectively. |
