近几年来,在集宁地区栽培的秋甘蓝的结球率在85％左右,影响产量很大。为什么呢? 一、品种混杂在播种育苗时,没有按要求选种,这样,就使品种严重退化,经过这种母株繁殖的种子,就使混杂现象严重发生,造成很大的损失,影响结球,既使结了球,也大小形状不一,所结的球松软,导致产量下降。二、秧苗不壮播种育苗时间不一致,使秧苗的苗龄不一致,有的成为所谓的“小老苗”。也有的
In recent years, the cultivation rate of autumn cabbage in Jining is about 85%, which has a great impact on yield. Why? First, the variety mixed In the sowing seedlings, did not select the required species, so that a serious deterioration of the species, after breeding of the mother of the seed, make the phenomenon of serious miscellaneous, causing great losses, affecting the knot Ball, even if the knot of the ball, also the size of different shapes, the resulting ball loose, leading to decline in production.
