黑龙江省小麦生育前期干旱少雨,是造成产量不高的主要原因之一。近年来干旱的威胁更有增无减。发展小麦灌溉,改变以水肥土为中心的生产条件以大幅度提高小麦产量,不仅是国内许多小麦高产地区的经验,也为我省生产实践和科学研究所证实。我省近三千万亩小麦,如果没有一定比例的灌溉栽培面积,产量就不可能有较大幅度的提高和稳定。必须在总结和推广抗旱栽培经验的同时,创造条件,因地制宜地积极发展小麦灌溉。
Heilongjiang Province wheat drought earlier, is one of the main causes of the yield is not high. The threat of drought has been increasing in recent years. The development of wheat irrigation and the change of production conditions centered on water and soil to greatly increase wheat output are not only the experiences of many high-yielding wheat areas in China, but also confirmed by our province’s production practices and scientific research institutes. Nearly 30 million mu of wheat in our province, if there is not a certain proportion of irrigated area, the yield can not be more substantial increase and stability. We must sum up and popularize the experience of drought-resistant cultivation and at the same time create the conditions for the active development of wheat irrigation according to local conditions.
