摘要
运用土壤普查和农业区划的科技成果，对黔东武陵山区中低产田土的区域特点、类型、主导障碍因素等方面进行分类，并根据中低产田类型进行综合治理。根据中低产田土的障碍类型和改良主攻方向，划分为干旱灌溉型、瘠薄培肥型、渍潜排水型3种类型，根据中低产田类型特征和改患对笨，采取综合治理技术，取得了显著的改土培肥和增产增收效果。采取完善配套工程、耕作培肥和农业技术措施，实现了以治本和治标相结合，土壤改良技术和农业增产技术相结合，注重消除土壤障碍因素，培肥熟化土壤，当年改造受益，有效改善农业生产、生态争件，增强稻田综合生产能力，提高基础地力水平；开展了6类试验研究，为项目实施提供了科学依据，3种类型中低产田土提高耕地地力0．5～1．5个等级，达到改土培肥、改善农产品质量，增产增收。
Using the science and technology achievements of the soil survey and the agricultural district planning, the mid-low yield land in Wuling mountainous area was classified according to the soil regional characteristics, soil types and the main yield limiting factors, etc. And its integrated improvement was carried out. The soils were classified into three types： dry-irrigation type, barren-fertilization type and wet-drainage type based on their main yield limiting factors and improving measures. The effects of increasing yields and incomes, and improving soil fertility were achieved by using the integrated technology based on the soil type characteristics and their improving measures. The soils were totally improved by completing the compound engineering, fertilization and agronomical technology. Combined soil improving technology with the technology of yield increased in agriculture, focused on the yield limiting factors elimination and the soil fertility improvement, the good results were got within a year. It improved the farming condition, ecological environment, enhanced the integrated productivity in paddy lands and raised the basic land productivity. The results from six kinds of field trials supplied the base information for the project practice. The farming land productivity levels of three mid-low yield soils were raised by 0. 5 - 1.5 grades, which achieved the goals of improving soll fertility raising crop yield and people＇s income.
