1982～1986年人工模拟池的试验结果表明,各还原物生成量随有机物施用量增加。随地下水位升高而增加,但并不随有机肥施用的增加而按比例呈直线上升,同时随着时间的延伸,地下水位的影响逐渐减弱。另外,各还原物生成量不同稻作制表现差异很大,其顺序为冬泡>冬绿>冬油,冬泡与冬种比较,还原物生成量差异显著,但冬绿与冬油差异不明显。

The results of artificial simulated ponds from 1982 to 1986 showed that the amount of each reduced matter increased with the amount of organic matter applied. But increased with the increase of groundwater level. However, it did not rise linearly with the increase of organic manure application. Meanwhile, the influence of groundwater level gradually weakened with the extension of time. In addition, there was significant difference in the yield of different types of rice. The order of the two types of yield was winter blight> winter green> winter oil, winter blister compared with winter, the difference was significant, but difference between winter green and winter oil was not obvious.
