近年来,由于春季少雨干旱,使江河水位下降,水田用水严重不足。然而水稻面积却一直在不断扩大。因此,采用苗期旱长后期水管的水稻旱种栽培,对发展我市水稻生产具有重要意义。为了探索省水、省工、高产、低成本的水稻旱种技术,我们从1983—1984年用两年时间进行了水稻旱种高产栽培试验,现将试验结果总结如下。 In recent years, due to the drought in spring, the water level of the river has dropped, and there is a serious shortage of water in the paddy field. However, rice area has been constantly expanding. Therefore, it is of great significance to develop paddy rice production in our city by using dry cultivation of rice in late stage of drought period. In order to explore the water-saving, labor-saving, high-yielding and low-cost rice cultivation techniques, we conducted a high-yielding cultivation experiment on dry cultivation of rice for two years from 1983 to 1984. The test results are summarized as follows.
