Potential Productivity of Main Crops in Meadow Soil District of Henan Province
摘要
Abstract
To search the potential of grain production and the limiting factors in crop production in Henan province,the photosynthetic production potential, the production potential of light and temperature, and the climate production potential were calculated based on the analysis of light,temperature,water and soil in alluvial soil areas of Tongxu country and Yanjin county. The results showed that the grain production potential in meadow soil was 15 535-21927 kg/ha,and the index of crop production potential was between 0. 21 and 0. 67. Analysis of the main limiting factors in crop production showed that the first one was water, and then was temperature and soil. At last the methods to further improve grain yield were proposed.关键词
