在吉林省东部湿润区,以先玉335为试验材料,针对不同施肥量下玉米去留分蘖处理对产量及构成因素进行研究。结果表明:去留分蘖不是影响收获产量的主要因素,生产中留分蘖能简化田间管理,具有节本增效的作用。氮磷钾肥施用比例是影响各处理产量及构成因素的主要因素,配施比例对去留分蘖产量及构成的影响较大。合理配施氮磷钾肥有利于提高玉米植株的生长及收获产量。
In the humid area of east Jilin Province, the yield and components of maize were planted under the different fertilizer levels using Xiangyu 335 as test material. The results showed that tillering is not the main factor affecting the yield of harvest, tillering in production can simplify field management, and has the effect of saving cost and increasing efficiency. The proportion of N, P, K fertilizers was the main factor affecting the yield and composition of each treatment. The proportion of N, P and K fertilizers had a significant impact on the yield and composition of the tiller. Rational application of N, P, K fertilizers is beneficial to increase the growth and yield of maize plants.
