花生地膜复盖,是花生栽培技术上的一项改革。1979年辽宁、山东等省首先在我国花生栽培上应用,取得了较好的成绩。1980年,我省在农业厅主持下,以兰考、开封等5个县为基点,进行了小面积的示范性试验,表现出一定的增产效果。1981年,又将试验扩大到郑州、民权、汝阳、淮阳、原阳等22个县、市,面积约120余亩,为1980年的24倍。为了进一步研究这项栽培技术的应用范围,提高花生地膜复盖的增产效益,现将我省有关试验结果并参考外地实践经验进行分析,提出几点粗浅看法,供讨论。
Peanut film covering, peanut cultivation is a technical reform. In 1979 Liaoning, Shandong and other provinces first applied in our peanut cultivation, and achieved good results. In 1980, the province under the auspices of the Agriculture Department, Lankao, Kaifeng and other five counties as the base, conducted a small area of the pilot demonstration, showing a certain increase in yield. In 1981, the trial was extended to 22 counties and cities in Zhengzhou, Minquan, Ruyang, Huaiyang and Yuanyang, covering an area of about 120 mu, 24 times that of 1980. In order to further study the scope of application of this cultivation technique and improve the yield-increasing benefits of peanut mulching, we present the relevant experimental results in our province and make reference to the field practical experience to analyze and put forward some superficial opinions for discussion.
