获得水稻高产稳产的关键是合理的肥水措施。只有对植稻土壤的氮素供应规律有所了解,对预测土壤氮素供应容量的方法有所掌握,才有可能根据高产水稻土壤供氮指标进行合理施肥。本文介绍的是关于这两方面的研究结果。试验方法供试土壤:石牌红砂岩定积土及中山县河
The key to achieving high and stable rice yield is a reasonable fertilizer and water measure. Only when we know about the nitrogen supply rule of rice plantation paddy, we can get a reasonable fertilization according to the method of predicting the soil nitrogen supply capacity. This article describes the results of these two studies. Test methods for the test soil: Shipai red sandstone soil and Zhongshan County River
