我省每年常有早春寒和夏初梅雨等灾害天气,影响西瓜等春种作物的生长。为了提早西瓜的上市季节和提高西瓜产量,我站从1981年开始进行地膜覆盖栽培西瓜试验,在取得初步经验的基础上,1982年又进行了较大面积的试验和应用。两年试验表明,地膜覆盖栽培西瓜具有明显的早熟和增产效应。现将试验初步结果报告如下.一、材料和方法试验在我站新开垦的红壤山地进行。
Every year in our province, there are often disastrous weather such as early spring cold and early summer rainy season, affecting the growth of spring crops such as watermelon. In order to early watermelon season and improve the watermelon production season, I station from 1981 began to test the cultivation of watermelon mulching, based on the initial experience gained, in 1982 and conducted a larger area of the test and application. Two years of experiments show that plastic film mulching watermelon has obvious precocity and yield effects. Now the preliminary results of the test are reported as follows: I. Materials and Methods The experiment was carried out on the newly reclaimed red soil in the mountainous area.
