望天田在稻田中占有一定比重,由于等天降雨和管理不善等原因,稻谷或旱粮年际间波动幅度大,效益低,极大地影响着大春粮食尤其是水稻生产的发展。针对望天田水稻和改种旱作的稳产高产问题,我所与各地从望天田的实际出发,作了大量研究及应用工作,结果表明,因田制宜地采用适应大面积望天田粮食生产需要的综合配套技术措施,就能稳定地提高望天田的粮食产量 Tiantian Tian occupies a certain proportion in the paddy field. Due to the constant rainfall and poor management, the fluctuation range and low efficiency of paddy or drought-prone crops during the year have greatly affected the development of spring rice, especially rice production. Aiming at the problem of stable and high yield of rice in the Tiantian field and dry farming with improved soil quality, we made a great deal of research and application work based on the reality of Wangtian field. The results show that, due to the field adaptation to the needs of large-scale Wangtian Tian food production, Comprehensive supporting technical measures, we can steadily improve Wangtian Tian’s grain output
