关于棉花落蕾落铃现象的生理原因,虽然许多人都曾加以研究,直到目前还没有一致同意的结论。为了揭露这一现象的本质,我们在1954和1955进行了两年的试验工作。 1953年的试验已指出土壤水分不足,株间光线强度减弱,盛花期後施用大量氮肥等情况下,都能增加棉花蕾铃的脱落。许多跡象都显示出蕾铃生长所须要的有机养料,能因为这些环境因素的影响而不能符合要求。所以阐明有机养料在棉花蕾铃脱落中的作用问题成为解决落蕾落铃不可缺少的先决步骤。醣是有机养料主要内容之一,仅仅是醣的增多,能否使幼铃的脱落大大的减低?在这方面
Although the physiological causes of cotton falling and falling bells have been studied by many people, until now no consensus has been reached. In order to reveal the nature of this phenomenon, we conducted two years of experimental work in 1954 and 1955. 1953 experiments have pointed out that the lack of soil moisture, light intensity between strains weakened, full bloom after the application of nitrogen fertilizer, etc., can increase the cotton buds fall off. There are many signs that the organic nutrients needed for the growth of buds can not meet the requirements due to the influence of these environmental factors. Therefore, clarify the role of organic nourishment in the fall of cotton boll has become an indispensable prerequisite step to solve the fall and fall off bolls. Sugar is one of the main content of organic nourishment, just the increase of sugar, whether the shedding of young bell greatly reduced? In this regard
