进行灌溉试验应尽先解决生产上迫切需要解决的主要问题,同时还要为将来在发展上进一步研究打下基础。必须运用先进科学理论结合群众经验,在不同土壤气象条件下层开试验工作。本文仅就冬小麦灌水时期、次数试验提出一般的进行方法,希各农业试验 Irrigation experiments should try their best to solve the major problems that are urgently needed to be solved in production and at the same time lay the foundation for further research on development in the future. We must apply advanced scientific theories in combination with the masses’ experiences in conducting experimental work under different soil meteorological conditions. This paper only on the winter wheat irrigation period, the number of tests put forward the general method, Xi agricultural trials
