在高寒山区无霜期较短的条件下,如何利用春小麦收获后的地茬,是很值得研究的问题。从1985年开始,我们在春小麦收获后种植京丰一号甘蓝,并采取各种措施,使京丰一号甘蓝生长期缩短到75天,产量逐年提高,1987年亩产达到3140公斤,叶球平均重2.5公斤,包心紧,品质好,收益高,为改进高寒
How to make use of the ground stubble after the harvest of spring wheat is a problem that is worth studying under the condition of short frost-free period in the alpine region. Since 1985, we planted Jingfeng No. 1 cabbage after the harvest of spring wheat and adopted various measures to shorten the growth period of the Jingfeng No. 1 cabbage to 75 days. The output increased year by year. In 1987, the annual output reached 3140 kg, The average weight of 2.5 kg, tight package, good quality, high returns, to improve the alpine
