佛山地区位于珠江三角洲,光、温、水资源丰富,土壤潜在肥力高,生产潜力大。但因土壤质地粘重,地下水位高、通透性差、还原物质积累多,连年种稻单产水平不易提高。本试验是在总结群众经验的基础上,以生产上沿用的两种粮、糖、油水旱轮作,配合土壤通气耕作法,进行定点研究,以期找出一种适应当地土壤条件,高产稳产、经济效益高的耕作制度。试验在佛山地区农科所(大茧围),由1982年春至1984年冬进行。轮作周期3年。一、试验方法按3年内水稻与旱作种植时间的比例,分
Foshan is located in the Pearl River Delta, light, warm water rich in soil potential high fertility, production potential. However, due to soil texture sticky, groundwater level is high, poor permeability, accumulation of reducing substances, perennial rice yield is not easy to increase. This experiment is based on summing up the experience of the masses, with the production of two kinds of grain, sugar, oil and water rotation, with soil aeration farming practices, conducted a fixed-point study to find a suitable soil conditions, high and stable yield, High economic efficiency farming system. The test was conducted in the Foshan Agricultural Science Institute (Dacoon Wai) from the spring of 1982 to the winter of 1984. The test The rotation period of 3 years. First, the test method according to the proportion of rice and dry planting in three years, points
