补充资料:大豆灌溉(irrigation of soybean)
 

大豆灌溉(irrigation of soybean)

在大豆生长发育过程中,根据土壤墒情,和大豆需水规律给予补充水分。大豆是需水较多的作用。开花前耗水量占全生育期需水量的10%,开花结荚期为60-70%,鼓粒期占20-30%,每形成1g干物质,需要耗水500g左右。

适宜大豆生长发育的土壤水分指标,为土壤田间最大持水量的65-70%,开花、结荚、鼓粒期为75-85%,当低于65%时,应及时灌溉。在干旱条件下,分枝期灌溉可增产4.1-9.4%;开花结荚前期灌溉增产12.0-27.6%,鼓粒期灌溉增产24.2-33.8%。

在东北地区大面积垄播条件下,普遍采用沟灌,在黄淮平原地区,每隔3m开一畦沟,每隔5m开一横沟,田的四周开边沟,沟渠要利用灌排,丘陵地区可采用喷灌。南方大豆产区,多畦田种植,采用浸润灌溉。
