随着农业生产的发展,棉花产量由亩产皮棉几十斤上升到百斤、二百斤以上。我省每年都有许多高产典型出现,但不稳产。如何掌握棉花高产、稳产、低成本是迫切需要研究解决的问题。为此,我们从1976年开始进行这一课题的研究,四年来(1976—1979年),从高产栽培技术到高产规律的探索均取得了一些资料,得到了初步结果。1976—1977年,进行了不同栽培方式的生产对比试验。分育苗移栽(4500株密度)、常规直播(5000株密度)与直播高密度(9000—10000株密度)三种方式,两年结果均
With the development of agricultural production, the output of cotton rose from several kilograms per mu of lint to over one hundred jin and over two hundred kilos. Every year in our province there are many high-yield typical, but not stable production. How to master the cotton high yield, stable yield and low cost is an urgent need to study and solve the problem. For this reason, we started to carry out the research on this subject from 1976, and some data have been obtained from the exploration of high-yielding cultivation techniques to high-yielding law in the past four years (1976-1979). Preliminary results have been obtained. 1976-1977, conducted a comparison of different cultivation methods of production. Seedling transplanting (4500 density), conventional direct seeding (5000 density) and direct seeding high density (9000-10000 density) in three ways, the results of two years
