我县每年播种小麦65万亩左右,占粮食总播种面积的40%,其中水地小麦在10万亩左右。1974年开始,我站在东胜永公社、东三分子生产队搞良种良法夺高产的试点,当年4.9亩“卡捷姆”平均亩产836斤,1975年又获得23.9亩平均亩产1,025斤,其中7.5亩平均亩产1,103.8斤。根据这两年的工作,对小麦高产中的几个问题,提出以下一些初步看法:一、最大叶面积系数多少合适?小麦是通过它的绿色部位——茎、叶、穗等利用太阳光能的,特别是单位土地面积上的叶面积大小与光合产物的多少有着直接关系。为了便于研究与比较,
Every year, 65 million mu of wheat are planted in our county, accounting for 40% of the total sown area of grain. Among them, about 100,000 mu of water are in the wheat field. Starting from 1974, I stood at Dongsheng Yong commune and the East Third Molecular Production Team tried out a pilot project of good seed and good law to win high output. In that year, 4.9 mu of “Kadim” averaged 836 kg of mu, and in 1975, it gained 23.9 mu of average mu yield of 1,025 kg , Of which 7.5 mu average yield 1,103.8 kg. According to these two years’ work, some preliminary opinions on some issues concerning high yield of wheat are as follows: 1. How much is the maximum leaf area coefficient? Wheat uses sunlight energy through its green parts - stems, leaves and spikes In particular, the size of leaf area per unit area of land is directly related to the amount of photosynthetic products. In order to facilitate research and comparison,
