开封县万隆公社荆科五队,在1978、1979两年,曾连续获得小面积花生亩产720斤.1980年倍加努力,计划争取亩产千斤,结果亩产只有410斤,这是为什么?经座谈了解,并分析对比了三年的田间记录和有关气象资料,认为三年的花生高产试验田均为菜园地,土质、品种、密度、底肥情况大体一致,仅施用化肥数量和气象条件不同,结果产量悬殊很大.现将具体情况和我们的体会,介绍如下,供参考.
Kaifeng County Bandung Jing Branch five teams, in 1978 and 1979, two consecutive years, has been a small area of peanut yield 720 kg in 1980 to work harder, plan to fight for a kilogram per mu yield of only 410 pounds, which is why? After three years of field records and relevant meteorological data, the three-year peanut high-yielding experimental fields were considered as vegetable garden. The soil quality, variety, density and base fertilizer were generally the same. Only the amount of chemical fertilizers and meteorological conditions were different, The results of a great disparity in output. Now the specific circumstances and our experience, introduced below, for reference.
