随着全球气候变暖,农作物种植区划和范围将随之发生变化,在新疆,历来以种植春油菜为主,但近年来,我们也尝试开展冬油菜北移集成技术研究示范,初步成功种植冬油菜。在北疆冬油菜8月底~9月中旬播种,翌年6月中下旬成熟,比春油菜提早成熟15~20天,冬油菜收获后剩余大量的光和热,可以再补种一茬早熟作物,充分利用光热资源,提高土地产出率。以奇台县2013年气候为例,7月、8月、9月平均温度分别在23.6℃、21.6℃、15.7℃;月日照时数
With the global warming, cropping zoning and scope will change, in Xinjiang, has always been the main spring planting rapeseed, but in recent years, we also try to carry out the winter rapeseed north integrated technology demonstration, the initial successful planting winter rape. In northern Xinjiang winter rapeseed from the end of August ~ September mid-seeding, the following year mature in mid-late June, early maturing spring rape 15 to 20 days, winter rape remaining a lot of light and heat after harvest, you can replant a crop of premature, Make full use of light and heat resources to improve land productivity. Taking the climate of Qitai County in 2013 as an example, the average temperatures in July, August and September are respectively 23.6 ℃, 21.6 ℃ and 15.7 ℃; the monthly sunshine hours
