昭盟春小麦灌溉试验自一九七三年开始,先后开展了春小麦需水规律试验;春小麦生育期灌水次数与产量关系的试验;不同生育阶段灌水增产效果对比及各生育阶段土壤适宜湿度的试验。一九七七年,根据试验资料,分析制定了春小麦灌溉制度及各生育阶段土壤湿度下限控制标准。一九七八年又开展了水、肥、密多因子正交试验,与此同时,也开始了试验成果的推广工作。由于几年来试验田增产效果显著,在社队干部和群众中起到了示范作用,为大面积
Zhaomeng spring wheat irrigation test since 1973, has carried out the spring wheat water demand test; Spring wheat growth period irrigation yield and yield test; different growth stages of irrigation yield contrast and soil fertility at each growth stage of the test. In 1977, based on the experimental data, the control system for the spring wheat irrigation system and the control limit of soil moisture at each growth stage was formulated and analyzed. In 1978, the Orthogonal Experiment of Water, Fertilizer and Multivitamin was carried out. At the same time, the promotion of experimental results began. Due to the remarkable effect of increasing yield in the experimental field in recent years, it has played an exemplary role in the cadres and masses of communes and social teams,
