1.间苗大豆出苗后,在全苗的基础上及早间苗,是一项行之有效的增产措施。其增产效果主要取决于间苗时间的早晚,一般在两片对生单叶展开时就要抓紧进行。据各地对比试验,间苗比不间苗的大豆增产10%～20%。2.压苗对大豆进行人工压苗,
1. Emergence of seedlings after the emergence of soybeans, seedlings and seedlings in the early morning, is an effective stimulation measures. The effect of increasing its production mainly depends on the time of the saplings, usually in the two unrolled leaves should pay close attention to. According to the comparative tests all over, Miao Miao than Miao Miao soybean yield 10% to 20%. 2 pressure seedlings artificial pressure on the soybean seedlings,
