气象条件是棉花生长发育重要的生态条件之一,而环境温度又是重要的气象条件之一。棉铃发育与环境温度尤为密切。棉花蕾铃脱落、铃期长短、铃重、纤维品质等都与温度有关。为深入探讨这些关系的密切程度,便于根据我省气候特点指导棉花生产,我们于1982年、1983年在南昌莲圹对岱字15号棉花品种进行了开花挂牌试验。现将试验结果简要总结如下:一、试验方法本试验82年4月15日播种,分每亩3000株和5000株二种密度,播种规格分别为
Meteorological conditions are one of the important ecological conditions for cotton growth and development, and the ambient temperature is one of the important meteorological conditions. Boll development and environmental temperature are particularly close. Falling cotton bolls, bell length, boll weight, fiber quality and so on are related to temperature. In order to further explore the closeness of these relations and to facilitate the production of cotton according to the climate characteristics of our province, we conducted the flowering and listing of cotton varieties of Dai Zi No. 15 in Lianqu, Nanchang, in 1982 and 1983. Now the test results are briefly summarized as follows: First, the test method This experiment April 15, 2002 sowing, points per acre 3000 and 5000 two kinds of density, sowing specifications were
