一九七六年在巴盟河套灌区试种水稻的社队,进行试种水稻问题的调查当中,发现有的地块播种后不出苗或出苗后生长一段时间又大量死亡,以及插秧后成活率低或不成活的现象。其主要原因之一可能是由于土壤盐分过高。为了明确这个问题,指导水稻生产,一九七七年我们在巴盟四分滩草籽场农一队稻田进行了种稻前地面洗盐效果的对比试验。现将试验结果简结如下。试验地为历年耕种的熟耕地,0～50厘米土层内为沙壤土,间有薄层红泥。但因盐碱
In 1976, the team of rice plants was planted in the Hetao Irrigation Area in Bameng to investigate the problem of rice cultivation. Some of the plots were found not to be sprouted or sprouted for a long time after sowing, and the survival rate after transplanting Low or not alive phenomenon. One of the main reasons may be due to excessive soil salinity. In order to clarify this issue and guide rice production, in 1977, we conducted a comparative experiment on the effect of salt washing on the ground before planting rice in a paddy field of a farm in the grass field of Baputan, Bameng. The test results are summarized below. The experiment was cultivated land cultivated over the years, sandy loam in 0-50 cm soil layer and thin layer of red mud in between. But because of salt
