黑龙江西部旱区大豆和玉米的节水灌溉计划研究
Water-saving Irrigation Schedulings of Soybean and Corn in the Western-arid Region of Heilongjiang Province
摘要
Abstract
The western area of Heilongjiang Province is one of the main regions for grain production and a base for commodity grain production in China.However in recent years,aridity frequently occurred in this region and greatly influenced crops＇ germination and growth.In this paper,we analyzed the water requirement of the main crops（soybean and corn） and the precipitation＇s distribution to find the water storage period,and consequently provide suitable water-saving technologies.Results showed that precipitation is enough to meet the water requirement of soybean and corn in July,while it is not sufficient in May,June,August and September.The total seasonal irrigation waters required are 157 mm and 142 mm,respectively,for soybean and corn.Fully considering local agronomic practices,we suggest using bed-irrigation sowing technology and ridge-plotted field method to increase crop germination rate and soil water content,and using sprinkler irrigation method in precipitation storage period of June and August to enhance crop growth.关键词
