近几年来,我省在深入开展“农业学大寨”的群众运动中,不断改革耕作制度,一年粮食三熟制的面积不断发展,这对发展粮食生产起了积极作用。据群众反映,在不少地区由于冬季大部分田都种上粮、油作物,相应减少了多季绿肥面积,发生了粮、肥争地的矛盾。为解决这些矛盾,我们在一九七二年冬进行了紫云英绿肥田套种小麦的试验,以摸索粮、肥双丰收的经验。一、试验情况:试验在本站实验农场内进行,采用大田示范与小区对比试验相结合。大田示范面积五亩。小区对此试验,每小区面积五厘,重复二次。试验田的土质属砂质壤土,肥力中等,前作物种植晚稻。紫云英在十月十一日采用稻底撒播,每亩播种量五斤,播种前
In recent years, our province has been constantly reforming the system of farming in the mass movement of “learning from agriculture in Dazhai”. The area under the three-year system of grain production has been continuously developing, which has played a positive role in the development of food production. According to reports from the masses, in many areas, grain and oil crops have been planted on most of the fields in winter, correspondingly reducing the area of multi-season green manures and contradictions over grain and fertilizer. In order to solve these contradictions, we conducted a trial of Shihlin-Yingda intercropping wheat in the winter of 1972 in order to explore the experience of double harvest of grain and fertilizer. First, the test situation: The experiment carried out within the experimental farm site, using field demonstration and plot comparison test. Daejeon demonstration area of five acres. Community test, the area of five centimeters per cell, repeated twice. Soil in the experimental field is sandy loam with medium fertility and late cropping of the former crop. Shihlin on the 11th of October using the bottom sowing, planting five acres per acre, before sowing
