我省丘陵地区由红壤母质发育的低产稻田,其主要特点之一是土壤板、结,多称为结板田。在改良这类低产田的过程中,群众反映:种植绿肥不仅禾苗生长良好,而且“泡土”。为了阐明这个问题,我们曾就不同绿肥对土壤结构与作物产量的影响,进行了观测,以期为改善与创造良好的土壤结构状况提供科学依据。 One of the main characteristics of the low-yield paddy rice developed from the parent material of red soils in the hilly areas of our province is the soil plate, the knot, and the multi-tiered paddy field. In the process of improving such low-yielding fields, the masses said that planting green manures not only gives good growth of seedlings, but also “soils.” In order to elucidate this issue, we have observed the effects of different green manure on soil structure and crop yield in order to provide a scientific basis for improving and creating a good soil structure.
