摘要
通过建立秋粮作物复合群体,将高产作物与耐旱作物按一定比例在固定尺带内间套种植,在作物搭配、带距配比、密度配置、适宜区域方面形成一定的技术规程并配合相应的配套技术,将能使复合群体有效适应以早为主的复杂的气候条件,大大增加作物收获的保险系数,达到旱年稳产保收,丰水年双增产的目的。
Intercropping of high-yielding crops with drought tolerant in accordance with acertain fixed bands of some sizes is practised through the establishment of the multiplepopulations.A certain technical specification together with a corresponding per-fectiontechnique has been formed in the matching of crops,crop distances and density for a cer-tain area,which can make the multiple popualtions suit to the complex weather condi-tions with droughts in the main to increase the coefficient of crop harvest so as toachieve the purposes of stable yields and harvest in dry year and double harvests in wa-ter rich year.
