摘要
为了分析黑龙江省西部半干旱地区滴灌条件下不同水分处理对大豆产量和水分利用效率的影响,于2009年在黑龙江省西南部的杜蒙县农业科技示范园区进行了不同灌水量处理的大豆滴灌试验。结果表明,滴灌大豆生育期耗水量随着灌水量的增加而增加;日耗水强度在结荚期达到最大,且各处理这一时期的日耗水量分别为4.3、4.8、5.1、5.4、2.3 mm.d-1;通过分析计算得出,大豆滴灌与不灌相比可使水分利用效率显著提高,在超过某一值后,土壤水分含量的提高并不明显;根据不同水分处理对大豆的产量和生长状态的影响,确定滴灌大豆适宜的灌水量为1 090 m.3hm-2。
In order to find the affect of the yield and water use efficiency of soybean with different water requirement in west semiarid region of Heilongjiang province, different treated soybean drip irrigation experiment was done in Dumeng agricultural demonstration zone which located in southwest of Heilongjiang Province in 2009. The results showed that water consumption of different water irrigation treatments increased with increased amount of irrigation water; In pod setting-seed filling stage, the Water Consumption Regularity of soybean was the most, they were 4.3, 4.8, 5.1, 5.4, 2.3 mm·d1; Through analyzing and computing, drip irrigation was very obvious in upgrading water use efficiency, but excess some ambit could not increase evidentially soil water content; According to the yield, water use efficiency and the growth of soybean, the water consumption was 1 090 m3. hm-2 during the whole stage.
