摘要: 以‘金来秋白2号’、‘金来秋白6号’为试材,研究株距、播期及施肥条件对其农艺性状的影响,以期确定2个早熟秋白菜品种的种植密度、播期和施肥水平。试验结果表明,‘金来秋白2号’、‘金来秋白6号’在50 cm的种植行距下,最适株距分别为40和45 cm。2个品种从7月初延续到8月末均可种植,且能保持较高的产量,7月15日-8月15日种植,净菜产量可达到75t/hm2以上。氮、磷、钾不同配施水平对大白菜产量有着重要的影响,氮肥的增产效果大于钾肥,磷肥效果最不明显。

Abstract: To determine the planting density, sowing date and fertilization level of two Chinese cabbage varieties, taking‘Jinlai Qiubai 2’and‘Jinlai Qiubai 6’as test materials, we studied the effects of row spacing, sowing date and fertilization condition on the agronomic traits. The test results showed that, under the 50 cm lining spacing of‘Jinlai Qiubai 2’and‘Jinlai Qiubai 6’, the best row spacing was 40 cm and 45 cm,respectively. The two Chinese cabbage varieties could be planted from early July to later August, whilst keeping high yield. Planting between July 15 to August 15, net vegetable production could reach 75 t/hm2 or more. The fertilizer application level of N, P and K had an important effect on the yield of Chinese cabbage. The yield increasing effect of N was more than that of K, and the fertilization effect of P was not obvious.
