“海涂综合开发利用”试验基地如东棉花原种场,地多劳力少,一人分管棉田8亩。过去采用直播棉,由于棉田土壤食盐量较高,立苗困难,密度不能保证,产量不高。近年来推广育苗移栽,增产效果显著,但由于农活过于集中,劳力紧张时,移栽往往不能及时,密度和质量也难保证,因此进一步扩大面积及提高产量受到限制。今年我们将1981、1982两年在南京卫岗本院进行的“双秆棉”试验成功的技术引用到如东棉花原种场,试验初步获得成 “TURP comprehensive development and utilization of” test base Rudong cotton seed field, more labor and less labor, one person in charge of 8 acres of cotton fields. In the past, live cotton was used. Due to the high salt content of soils in the cotton fields, it is difficult to stand seedlings and the density can not be guaranteed and the yield is not high. In recent years, the promotion of seedling transplanting has produced remarkable results. However, due to the concentration of farm work and labor shortage, the transplanting is often not timely and the density and quality are hard to guarantee. Therefore, further expansion of the area and increase of output are limited. This year we will 1981, 1982 two years in Nanjing Weigang Hospital “double stalk cotton” successful trial of technology quoted Rudong cotton seed field, the initial test obtained
