创造高产稳产的土壤条件,大幅度提高土壤生产率是我国农业现代化的重要内容,也是当前土壤科学研究中的最重大课题。一九七六年以来,我所针对我地区丘陵与湖区中当前双季稻实际亩产量超“双纲”或接近“双纲”的历年高产稻田50丘和低产田20丘进行定点对比观测研究,据初步研究结果认为:在保证山、水、田、林、路综合治理,创造一个旱涝保收,条田成方,土地平整,排灌自如,无“三水”为害(地面的渍水、洪
It is an important part of agricultural modernization in our country to create the soil conditions with high and stable yield and greatly increase the soil productivity. It is also the most important issue in current soil science research. Since 1976, we conducted a fixed-point comparison study on the actual production of double-cropped double-cropped or double-planted paddy fields in the past 50 years of high-yield paddy fields and 20 low-yield fields in the past two years in current hilly and lacustrine areas According to the preliminary study results, it is believed that in the comprehensive management of mountain, water, field, forest and road, it is possible to create a flood and drought protected area, create fields and fields, land leveling, drainage and irrigation facilities free from “three water” damage
