水稻旱育秧不仅节水,而且秧苗素质好。但在盐碱地存在着两大障碍,一是盐害,二是立枯病严重。为了解决这两个难题,我们在学习盘山经验的基础上,于1982—1983年进行了水稻旱育秧的生产试验。试验地播前取0—20厘米土层测定,全盐量0.13%,氯离子为0.028%,重碳酸根为0.028%,有机质含量1.24%,全氮0.075%,碱解氮58ppm。试
Rice dry nursery not only water-saving, but also good quality seedlings. However, there are two major obstacles in the saline-alkali soil, one is the salt damage, and the other is the serious disease of the blight. In order to solve these two problems, we conducted the experiment of producing dry rice seedlings in 1982-1983 on the basis of learning Panshan’s experience. Soil samples were taken from 0-20 cm soil before sowing. Total salt content was 0.13%, chloride content was 0.028%, bicarbonate content was 0.028%, organic matter content was 1.24%, total nitrogen content was 0.075% and nitrogen content was 58ppm. test
