本文以尿素和过磷酸钙为材料,用三种不同氮肥水平和五种不同磷肥水平,配合成十五个组合为手段,研究了不同NP配施对苏啤1号产量和品质的影响,主要结果是NP配施其亩产、斤养分坛产量、亩纯收益,肥料投资率和品质均优于单施N处理。氮肥对提高产量有明显效果,氮磷配施对提高产量、经济效益和改善籽粒品质(提高淀粉含量、降低蛋白质含量)有显著作用。N/P值相同,高一级施肥水平优于低一级施肥水平。对氮磷配合比例提出了因土因肥而异的配合原则。
In this paper, urea and calcium superphosphate as materials, with three different levels of nitrogen and five different levels of phosphate fertilizer, combined with 15 combinations as a means to study the impact of different NP application on the yield and quality of Supi 1, the main The result is NP with its output per mu, pound yield, pure net income, fertilizer investment rate and quality are better than the single application of N treatment. Nitrogen fertilizer has obvious effect on increasing yield. The combination of nitrogen and phosphorus plays a significant role in improving yield, economic benefit and improving grain quality (increasing starch content and reducing protein content). N / P value of the same high level of fertilization level is better than the low level of fertilization level. Proportion of nitrogen and phosphorus put forward due to soil fertility and the principle of cooperation.
