为了延长棉花生育期,充分利用无霜季节,促进早熟,提高产量。从一九六五年开始,我们对棉花干籽早播的技术措施进行了多次小面积试验。到一九七五年开始较大面积示范,一九七八年全省示范推广到30多万亩。经过十多年的反复实验示范,初步认为棉花干籽早播有省工、全苗、增产和利于机械耕作的优点,是夺取棉花高产再高产的一条有效措施。
In order to extend the growth period of cotton, make full use of frost-free season, promote early maturity, increase production. Since 1965, we conducted a number of small-area tests on the technical measures for early seeding of cotton dry seeds. By 1975, demonstration of a larger area will begin. In 1978, the province’s model was popularized to more than 300,000 mu. After more than ten years of repeated experiments and demonstrations, it has been preliminarily believed that the advantages of early harvesting of cotton dry seeds such as provincial work, whole seedling, yield increase and mechanical tillage are the effective measures to seize high yield and then high yield of cotton.
