去年蛟河等地大豆单产比历年偏高,一般0.1公顷达250～300公斤以上。7月份严重干旱以为会引起大量落花落荚势必减产,但秋后却见到较好收成。总结起来,有两点主要原因: 1.茬口优势。近几年玉米播种面积偏大,但去年开始有所减少,而大豆面积增多,重、迎茬现象降低,茬口优势有利于大豆单产的提高。 2、去年大旱之年气候条件虽不利,但对大豆生长的两个需肥高峰
Last year, soybeans and other places in Jiaohe yield higher than in previous years, generally 0.1 hectare up to 250 to 300 kg. Severe drought in July is bound to lead to massive drop of pods is bound to cut, but in the fall have seen a better harvest. To sum up, there are two main reasons: 1. Stubble advantage. In recent years, corn sown area is too large, but began to decrease last year, while the soybean area increased, heavy, reduced the phenomenon of stubble, crop advantage is conducive to soybean yield increase. 2, last year’s drought year, the climatic conditions are not conducive, but the growth of the two soybean need fertilizer peak
