棉花增产的几个技术问题我省处于无霜期短的特早熟棉区。春秋两季多低温,高温期不长。但棉花是喜温喜光,生育期长的作物,因此,“一长一短”(棉花生育期长与无霜期短)“一高一低”(棉花需要积温高与实际积温低)的矛盾比较突出。为此,我省在棉花丰产栽培技术上的战略措施是立足抗灾,狠抓“早”字,落实
Several technical problems of cotton production increase Our province is in the frost-free period of the precocious cotton area. Spring and autumn and more low temperature, high temperature is not long. However, cotton is a pleasant and warm crop with a long growing period. Therefore, the contradiction between “one long and one short” (long cotton growth period and short frost-free period) “one high and one low” (cotton requires high accumulated temperature and low actual accumulated temperature) . To this end, our province in cotton high yield cultivation technology strategy is based on the disaster, pay close attention to “early” word, implement
