花生地膜覆盖栽培技术于1979年引入我国辽宁、山东等省试验研究,其增产幅度13.1-69.7%,我省1980年进行示范试验,增产效果不甚显著.为了进一步研究在我省的应用价值,我所1981年结合高产栽培试验,在2.25亩地内设0.21亩不覆盖为对照区,定期取样测定生育动态,现将试验结果简结如下.一、试验概况:该地为砂壤土,前茬夏红薯,灌溉排水条件良好.在冬耕的基础上,每亩施用杂肥9400斤,4月5日深耕25-27厘米,并进行斜耙灌底墒水后,于4月15日每亩施肥5000斤,草木灰200斤,豆饼170斤,过磷酸钙110斤,浅耕5-6寸,斜耙后每亩沟施种肥1250
Peanut plastic film mulching cultivation technology was introduced into the pilot study of Liaoning, Shandong and other provinces in China in 1979, with an increase rate of 13.1-69.7%. In 1980, demonstration experiment was conducted in our province with no significant increase in yield. In order to further study the application value in our province, In 1981, we combined high-yielding cultivation experiment with 0.21 mu of non-covered control area in 2.25 mu of land, and regularly sampled and measured the growth dynamics. The test results are summarized as follows: I. Test Overview: The area is sandy loam, Summer sweet potato, irrigation and drainage conditions are good.On the basis of winter farming, the application of 9400 pounds of mixed fertilizer per acre, deep plowing 25-27 cm on April 5, and after rake water irrigation at the end of irrigation, fertilization on April 15 per acre 5000 pounds, 200 kg of ash, soybean cake 170 pounds, 110 pounds of superphosphate, shallow plowing 5-6 inch, after rake rake 12000 acres of fertilizer per mu
