| 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...

| 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 ... |
