土面增温剂是一种农田化学复盖物,施用后能抑止土壤水分蒸发,减少热量消耗,增加地温。因此,它在一定程度上能起到尼龙薄膜的作用。据外省试验,效果很好,但在我处尚无经验。为了摸索其使用方法,1978年我们分别在钱桥公社一大队五队和头桥公社红旗十队作早稻育秧试验,结果如下。一、试验方法。钱桥公社一大队五队的早稻育秧试验,田块土质相同,品种为中秆早。土面增温剂处理的小区,于4月6日播种,搨谷后4小时,每亩用土面增温剂原液180斤,1:3倍喷雾。4~5小时后结膜。5月10日移栽,面积为0.514亩。尼龙薄膜育秧于4月5日播种,移栽前揭膜炼苗,于5月4日移栽,面积2亩。在头桥公社红旗十队,选择有代表性的田块作小区试验,品种为原丰早,
Soil warming agent is a farmland chemical covering, after application can inhibit the evaporation of soil moisture, reduce heat consumption, increase ground temperature. Therefore, it can play the role of nylon film to a certain extent. According to the provincial test, the effect is very good, but I have no experience at this place. In order to explore its use, in 1978 we were in Qianqiao commune a brigade five teams and the first bridge red flag ten communes team for early rice seedling test results are as follows. First, the test method. Qianqiao commune a brigade five teams of early rice seedling experiment, the same soil plots, varieties of straw in the early. Soil warming agent to deal with the plot, sown on April 6, four hours after the extension of the valley, with muck soil warming liquid 180 pounds, 1: 3 times the spray. 4 to 5 hours after the conjunctiva. May 10 transplanting, an area of 0.514 acres. Nylon film seedlings planted in April 5, before tearing shed filming transplanting, on May 4 transplanting, an area of 2 acres. In the first bridge red flag ten communes, select a representative plots plots for the trial, the varieties of the original abundance morning,
