Effects of Different Agronomic Measures on Two Precocious Chinese Cabbage Varieties
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.
