为了更好地把气象工作纳入以农业为基础的轨道,为农业学大寨作出新贡献,在市气象局的领导和部署下,由南汇县气象站负责召集上海市郊区五千重点产棉县的十六个气象哨组成棉花农业气象试验协作组,对棉花出苗的温度、湿度条件进行了专题研究,现将研究结果综合简介如下:一、土壤湿度与棉花出苗的关系棉花的出苗除了适当的温度条件外,还要有适宜的土壤湿度。协作组各试验点,用当地的土壤晒干后,测定其基本含水量,分别装入盆钵中,然后按不同土壤的最大持水量加水配制成15%、20%、25%、30%、35%、40%和45%等七种不同土壤湿度。把
In order to better integrate meteorological work into the agriculture-based track and make new contributions to agriculture Dazhai, under the leadership and deployment of the Municipal Meteorological Bureau, Nanhui County Meteorological Station is responsible for convening 5,000 key cotton-producing counties in the suburbs of Shanghai Of the 16 meteorological whistle cotton weather meteorological experimental group composed of cotton sprouting temperature and humidity conditions of a special study, the research results are summarized below: First, the relationship between soil moisture and cotton emergence In addition to the appropriate emergence of cotton Temperature conditions, but also have appropriate soil moisture. The experimental groups in the cooperative group were sun-dried with the local soil and then measured their basic water content, respectively, into pots, and then made into 15%, 20%, 25% and 30% water according to the maximum water holding capacity of different soils. 35%, 40% and 45% of seven different soil moisture.
