海岛棉是优质的棉花品种,它的纤维比一般陆地棉长,而且品质好,是高级棉织品必需的纤维。由于海岛棉生育期长,从青铃到吐絮结束,长达100天左右,收花经常要延续到霜冻后,不少青铃因低温不能正常吐絮,严重影响棉花品质和后作耕种。去年五四农场与植生所协作,试用乙烯利催熟海岛棉,进行了不同浓度、不同时期乙烯利处理,初步结果如下:一、棉铃开始吐絮到吐絮60%以上,不同生长类型的棉花(正常、迟熟、疯长、贪青),
Island cotton is a high-quality cotton variety. Its fibers are longer than normal upland cotton and have good quality and are the staple fiber for premium cotton. Due to the long period of growth of island cotton, from the end of the green bell to the end of the boll opening up to about 100 days, the flowers are often extended to the frost. Many of the Qingling bolls can not be properly swallowed due to the low temperature, seriously affecting the quality of the cotton and subsequent cultivation. Last year, the May Fourth Farm collaborated with the Institute of Botany to test the ripening of the island cotton with ethephon. The results were as follows: First, the cotton boll began to flocculate more than 60% of the bolls of cotton floss, with different growth types (normal , Late maturity, insane, greedy),
