摘  要:
坐水种技术是东北半干旱区为应对区域春旱的一项重要的保苗措施,一般可增产12%以上。一般采用专用坐水播种机进行作业,在东北褐土地区当0~20 cm土层重量含水量为6%~8%时,玉米坐水量为60~90 m3/hm2,大豆和花生为80~100 m3/hm2;土壤含水量为8%~10%时,玉米坐水量为45~65 m3/hm2,大豆和花生为55~75 m3/hm2;土壤含水量为10%~12%时,玉米坐水量为30~50 m3/hm2,大豆和花生坐水量为40~60 m3/hm2。

摘  要:
Sowing with water was an important measure for?keeping crop seedling from drought in the semiarid area of northeast China. The technique had yield-increasing effect of 12%. Special sowing with water machine should be used in the operation. In the cinnamon soil area, when 0 ~20 cm soil weight moisture content was 6%~8%, irrigation quantity of maize for 60~90 m3/hm2. and soybean or peanut for 80~100 m3/hm2;When soil weight moisture content was 8%~10%, irrigation quantity of maize for 45~65 m3/hm2, and soybean or peanut for 45~65 m3/hm2; When soil weight moisture content was 10%~12%, irrigation quantity of maize for30~50 m3/hm2, and soybean or peanut for 40~60 m3/hm2.
