金县大魏家公社过去谷子产量一直很低,近年来单产只有200斤左右,因此谷子面积日趋减少。为了扩大谷子面积和提高单产,从1980年开始,通过对高产地块和低产地块的调查发现:凡是早播的谷子(小满以前播种),空壳多,产量低;晚播的谷子(小满以后播种)空壳少,产量高。如五家大队四队1980年5月28日播种2亩偃师谷子,亩产784斤;刘家大队六队1981年在萝卜栽子下茬播种锦谷9号1亩,单产621斤;而金家三队连续两年在4月末5月初播种,单产都没有超过300斤。为了探讨谷子空壳多产量低的原因,1982年在五家一队进行了谷子播种试验。一、试验材料和方法供试品种为锦谷9号。从谷雨至夏至共5个播期。田间设计为顺序排列,3次重复,每
In the past, the production of millet in the Weijia Commune in Jinxian County has been very low. In recent years, the yield per head has reached only about 200 kilograms, and the millet area has been decreasing. In order to expand the area of millet and increase yields, from 1980, the survey of high-yielding plots and low-yield plots found that: All early-season millet (sown earlier than Xiaoman) had many empty shells and low yield; late-season millet After sowing) less shell, high yield. Such as the five brigade four teams May 28, 1980 sowing 2 acres Yanshi Millet, 784 pounds per mu; Liu team brigade in 1981 in the radish plant sowing Jin Gu 9 1 mu, yield 621 kg; and Gold three teams for two consecutive years in late April and early May sowing, no more than 300 pounds per unit yield. In order to investigate the reasons for the low yield of millet shell, the first team of five in 1982 conducted the experiment of millet seeding. First, the test materials and methods for the test varieties Jinyou 9th. From Guyu to summer solstice a total of 5 sowing date. The field designs are arranged in order, three times in a row, each
