近两年来,塑料薄膜保温育秧在生产实践中获得了良好效果。但塑料薄膜育秧成本高,如能改进薄膜育秧方法,提高成秧率,增加秧田栽植指数,相对地即降低了成本。为此,我们在北京市中阿人民公社基点工作组进行了塑料薄膜育秧与每穴不同插植苗数(1、2、3、4苗)的对比试验,现将结果简介如下。 The past two years, plastic film insulation seedlings in the production practice has achieved good results. However, the high cost of plastic film seedling raising, such as film seedling can improve the method to improve the rate of seedling planting, planting seedling increase index, which is relatively reduced costs. To this end, we conducted a comparative study on the plastic film seedling cultivation and the number of different planting seedlings (1, 2, 3, 4 seedlings) per hole in the Beijing-Alaska People’s Commune Base Point Working Group. The results are summarized as follows.
