河西走廊高海拔冷凉区白菜适宜种植密度研究

摘要

Taking Sijiwang Chinese cabbage as material in Hexi Corridor high-altitude cold areas,different planting densities were designed to study the effects of different planting density on the yield and the economic traits of Chinese cabbage.The results indicated that plant height,stem diameter,stem length and weight per plant showed a rising trend with the increasing of planting density.The highest yield of Chinese cabbage was got under the planting spacing of 35 cm×30 cm.The planting spacing of 35 cm×30 cm was suitable in Hexi Corridor high-altitude cold areas.%在甘肃河西走廊高海拔冷凉区以四季王白菜为试材,研究不同种植密度对白菜产量及经济性状的影响。结果表明：随着种植密度的增加,白菜的株高、球茎长、球茎粗、单重逐渐降低;栽植株行距为35 cm×30 cm下白菜产量、效益最高。因此,河西走廊高海拔冷凉区白菜适宜种植株行距为35 cm×30 cm。
