本文对豫南地区农业气候热量资源的特征、变化规律及保证机率进行了分析,结合本地区主要轮作制和亚热带多年生木本作物的生长,进行了热量条件的农业评价,揭示出限制本地区热量资源充分利用的不利气候条件及防御措施,提出了合理利用热量资源发展农业生产的途径。文章最后提出,不论从当前还是从长远的观点看,发展本地区农业生产的途径,应从两方面着眼,一是合理轮作用地养地结合,适当提高现有耕地的复种指数。二是因地制宜综合开发山区,建立以多年生木本作物为对象的农业。作者认为,豫南大别、桐柏山地区,有条件逐步发展成为河南省的亚热带作物基地。
In this paper, we analyzed the characteristics, the changing rules and the guaranteed probabilities of agricultural climatic heat resources in southern area of Henan Province. Combining with the main rotation system in the region and the growth of perennial woody crops in subtropical regions, agricultural evaluation of caloric conditions was conducted, Resources and make full use of unfavorable climatic conditions and defensive measures, put forward the rational use of heat resources to develop agricultural production ways. The article concludes that no matter from the current or long-term point of view, the ways to develop agricultural production in this region should focus on two aspects. Firstly, combine rationally and rationally and raise the multiplying index of existing cultivated land appropriately. Second, due to local conditions, comprehensive development of mountainous areas, the establishment of perennial woody crops for agriculture. The author believes that the southern Henan Dapu, Tongbai Mountain area, conditions and gradually developed into a subtropical crop base in Henan Province.
