近年来,棉花育苗移栽面积有了大幅度增长。1977年全国育苗移栽面积已达600多万亩,至今还在逐年扩大。广大贫下中农在生产实践中认识到棉花育苗移栽是实现高产再高产的一条重要途径。两年来通过试验逐步认识到大麦虽比小麦成熟期早半个多月,有利棉苗早移和早发,是移栽棉花的好茬口。但由于大麦经济价值低,单产又不如小麦高,本地仅作饲料用。同时,又因本地区以早熟三号大麦作当家品种,具有病害严重不耐低温等缺点,今后面积还会缩减。为此,我们1977年在大麦茬的基础上,进一步开展小麦茬育苗移栽的试验研究。
In recent years, cotton seedling transplanting area has increased dramatically. In 1977, the transplanting area of seedlings in the whole country reached more than 600 million mu and it is still expanding year by year. The majority of poor and middle peasants in production practice recognize that cotton seedling transplanting is an important way to achieve high yield and then high yield. Over the past two years through experiments and gradually realized that barley, although more than half a month earlier than the wheat maturity, early cotton seedling is advantageous and early hair, cotton is a good crop transplanted. However, due to the low economic value of barley, yield is not as high as wheat, the local feed only for use. At the same time, because of the region to precocious three barley as a species, with severe disease and other shortcomings of low temperature, the future will be reduced. To this end, we in 1977 on the basis of barley stubble, further carry out the experimental study of transplanting of wheat stubble seedlings.
