生产中,人们常以为大白菜的栽培技术没有黄瓜、番茄等蔬菜所要求的生产技术水平高,但要想获得高产,就必须从播种开始下功夫。因此,提高播种质量是保证大白菜一次播种苗全、苗齐、苗壮,减少小苗次苗,提高产量和商品等级的基础。为此,在大白菜播种时要做到: 一、细致整地,施肥均匀。将前茬作物的残枝落叶清理干净,早倒茬的地块尽量早翻、晒茬,做底肥的有机肥要充分腐熟并捣碎。 Production, people often think that the cultivation techniques of Chinese cabbage without cucumber, tomatoes and other vegetables required high level of production technology, but in order to obtain high yield, we must start from sowing time. Therefore, to improve sowing quality is to ensure that the first sowing seedlings of Chinese cabbage, Miao Qi, Miao Zhuang, reduce the number of secondary seedlings, increase production and product grade basis. To do this, when sowing Chinese cabbage to do: First, meticulous land preparation, fertilizer evenly.
