【摘要】 研究棉花子叶期遭遇冰雹形成不同危害型棉株生长发育程度的差异。试验结果表明,单子叶型棉株、生长点型棉株比正常棉株均表现为生长缓慢,抗逆性差,产量水平降低,尤其生长点型棉株霜前子棉产量比正常棉株降低70%,应该毁种。更多还原

【Abstract】 The test is done to study the growing of different type of cotton destroyed by hail-stones during cotyledon period, the results showed: cotton with one-cotyledon and cotton only with growing-point are slower in growing、worse in resistance and lower in yield than normal cotton with two-cotyledons, especially the pre-frost yield of cotton only with growing-point reduces 70 percent, it should be exterminate.更多还原
