Demonstration and Extension of Cultivation Techniques for High Yield of Grain Crops in Semiarid Areas in Southeast Inner Mongolia

１９８８年～１９９７年在内蒙古宁城县选择地理位置不同、无灌溉条件的示范小区，对谷子、玉米和高粱等主要粮食作物进行旱作高产栽培技术示范研究和大面积推广，主要粮食作物增产７０．５３％，实现自然降水生产效率７．８４ｋｇ／（ｍｍ·ｈｍ２），其中１９９５年～１９９７年达到１０．０６ｋｇ／（ｍｍ·ｈｍ２）。

Demonstration and large scale extension of cultivation techniques for high yield of grain crops such as millet, maize and sorghum were carried out from 1988￣1997 in several demonstration bases distributed in different geographical positions without irrigation condition in Ningcheng County of Inner Mongolia, which achieved 70.53% increase of the yild of major grain crops and obtained 7.84 kg/mm·hm of productivity of natural precipitation which reach 10.06 kg/mm·hm from 1995￣1997.
