充分利用自然资源,提高复种指数是挖掘农业生产潜力的有效途径之一。我区土默川、河套、西辽河及哲盟赤峰南部一些地区,一般小麦收获之后还有八十天左右的休闲时间和三分之一的光热,光照在780～850小时,≥10℃的积温达1100～1800℃以及二分之一的降雨量(约170毫米)等宝贵自然资源,可供利用。充分利用这些条件,复种麦茬青割大麦、小黑麦或燕麦等,对增产、增收,发展农区牧业,促进农牧结合都具有很大意义。
Making full use of natural resources and improving the multiple cropping index are one of the effective ways to tap the potential of agricultural production. In some areas of Tumochuan, Hetao, Xiliaohe and Cheney in Southern part of Chifeng, there are about 80 days of leisure time and one-third of light and heat after the harvest of wheat in general. The light is 780-850 hours, ≥10 ℃ The accumulated natural temperature of 1100-1800 ° C and one half of the rainfall (about 170 mm) are valuable natural resources available for use. Taking full advantage of these conditions, multiple cropping of wheat, barley, triticale or oats will be of great significance for increasing production, increasing income, developing farmland husbandry and promoting the integration of agriculture and animal husbandry.
