摘要
采用盆栽和池栽相结合的方法,研究不同肥料配施对高赖氨酸玉米(中单9409)产量和品质的影响。结果表明:施氮肥可明显增加其子粒产量,且子粒中游离氨基酸总量和蛋白质含量均有提高,但子粒中赖氨酸的含量却明显降低。氮、磷、钾配施或在此基础上增施微肥,不仅可以加速子粒的发育,提高千粒重,增加穗长,减少秃尖,增加单穗粒重,产量提高,而且可提高子粒中蛋白质和赖氨酸的含量。单施有机肥对高赖氨酸玉米产量和品质的改善效果不明显。
With both pot and pond cultivation the experiments mentioned in this article intend to research the effect of different fertilizers ( including organic manure, N-P-K fertilizer and microelement fertilizer) application on the yield and quality of high lysine corn. The findings indicated that , on the whole, N fertilizing can increase not only the high lysine corn's yield but the content of and amino acide in the seed. But the lysine content reduced. NPK cooperating or adding microelement fertilizer not only can increase the speed of seed, the weight of 1000 seeds,the length and weight of spike, and shorten the length of bare needle, but also increase the content of protein and lysine in the seed. Only organic manure application could not come into being improduced effects in both yield and quality.
