百色市主要农作物土地生产潜力研究

[目的]探讨百色市主要农作物的土地生产潜力估算方法,为提高百色市主要农作物的土地生产潜力提供参考.[方法]用农业生态区域法估算主要农作物的光温生产潜力;在光温生产潜力的基础上用水分订正系数进行修订,估算出主要农作物的气候生产潜力;在气候生产潜力基础上用土地质量系数进行修订,估算出主要农作物的土地生产潜力.[结果]百色市主要农作物光温、气候和土地生产潜力均以水稻最高,其余依次为玉米、大豆和红薯.4种作物土地生产潜力分别为：5466.0、5074.4、2414.3和1190.5 kg/ha.[结论]百色市主要农作物的土地生产潜力较低,为提高百色市主要农作物的土地生产潜力,应优化农作物品种结构,引进高产优质的农作物品种,提高土壤肥力,加强水肥管理和以农田水利为重点的农业基础设施建设等.

Land production potential of main crops in Baise City

[Objective]The objective of this study was to investigate land production potential of main crops in Baise City in oroler to provide references for expanding their potential.[Method]The light and temperature production potential of main crop was estimated using the agro-ecological zones method,then the climate production potential of main crop was estimated on the basis of the production potential of light and temperature and the moisture correction coefficient,finally the land production potential of main crop was estimated on the basis of the climate production potential and land quality coefficient.[Result] Rice had the highest production potential of light and temperature,climate and land,followed by maize,soybean and sweet potato.The land production potentials of the four crops were 5466.0,5074.4,2414.3 and 1190.5 kg/ha,respectively.[Conclusion]Land production potential of main crops in Baise City was relatively low.To increase the land production potential of main crops in Baise City,the following measures must be taken,i.e.optimizing the structure of main crop varieties,introducing new crop varieties with high yield and quality,increasing soil fertility,strengthening fertilization and irrigation management,and advancing the construction of agricultural infrastructure such as irrigation and water conservancy.
