摘  要:
黑龙江西部地区为我国的粮食主产区和重要的商品粮基地,频繁发生的春旱已经严重影响了作物的播种和苗期生长。通过分析该区主要作物(大豆和玉米)需水规律和降水分布的关系,明确作物缺水的主要阶段,提出适宜的节水技术。研究发现,在大豆和玉米生长的阶段内,除7月降水量能够满足大豆和玉米的需水量之外,其他月份的降水量均不能满足作物需水量,生育阶段的缺水量分别为157mm和142mm。结合当地的种植模式,建议在5月份通过坐水种和垄向区田等技术,提高出苗率和土壤含水量,在作物缺水的6月和8月份,可通过喷灌等灌水技术补充土壤水分,促进大豆和玉米生长。

摘  要:
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.
