我团自1986年推广玉米地膜栽培以来,玉米生产出现了大的飞跃.1986年种植地膜玉米50亩,单产900.5公斤,1987年扩大到2823亩,平均单产达750公斤.两年实践表明,玉米地膜覆盖栽培与裸地玉米相比,单产提高60—80%,经济效益提高70%,水的效益提高60—90%.我们通过两年种植地膜玉米的实践体会到,欲获地膜玉米丰产,应着重解决以下几个问题.
Since the promotion of corn film cultivation in 1986, a great leap forward has been made in the production of corn in 1986. In 1986, 50 mu of plastic mulched corn was planted, yielding 900.5 kilograms per mu and expanding to 2823 mu in 1987 with an average yield of 750 kilograms. Two years of practice showed that corn Film-mulching cultivation compared with bare corn, yield increased by 60-80%, economic benefits increased by 70%, water efficiency increased by 60-90% .Through the practice of planting maize two years of experience, to get the plastic film mulberry yield, Should focus on solving the following questions.
