冬小麦越冬前灌冻水是新出现而亟待解决的农业技术问题之一。这里所说的冻水,是指当麦田结冻前后所浇的一次水而言。年来华北、西北各地,对小麦冻水浇与不浇,早浇和晚浇,没有一致的认识;报导的结果,也不相同。1952年冬,苏联专家伊万诺夫同志在京讲学时,对浇冻水问题,提出不同的意见,并指示应作试验,从理论上说明它。现在我把搜集到 Pre-freezing irrigation of winter wheat is one of the emerging agricultural technical problems to be solved. Frozen water here, refers to when the wheat field before and after freezing a water. Over the past years, there has been no consistent understanding of pouring or not pouring cold water on wheat in North China and Northwest China. The reported results are not the same either. In the winter of 1952, Comrade Ivanov made a comment on the problem of pouring frozen water in his lectures in Beijing and instructed that a test should be made to explain it theoretically. Now I collect it
