在连续三年的秋白菜高产攻关试验中,进行了播前悬耕与不悬耕大面积对比试验。试验面积5公顷,试验地块有机质为2.84％,速效氮为128PPm,速效磷为14.94PPm,速效钾为159PPm,试验品种为牡丹江一号白菜。处理区要求早春草芽萌发后先悬耕,深度为18—20cm,当草芽第二次萌发时再起垄,起垄必须在播前10—15天之前完成。对照区早春整地后起垄,播前需铲一遍地。悬耕费用与铲地
In three consecutive years of autumn cabbage high yield test, carried out before sowing and non-suspending large-scale comparative experiments. The experimental area of 5 hectares, the experimental plot of organic matter was 2.84%, available nitrogen was 128PPm, available phosphorus was 14.94PPm, available potassium 159PPm, test varieties for the Chinese cabbage No. 1 Mudanjiang. Treatment area requires early spring grass sprouting after the first plow, the depth of 18-20cm, when the second germination of grass buds again Ridge Ridge must be completed 10-15 days before sowing. Control area in early spring ridge after planting, shovel before sowing again. Tillage costs and shoveling
