摘要
本文采用应用研究与基础理论研究相结合的方法,对水稻的需水规律与产量关系进行定量分析,以优化灌溉模式进行土壤水分调节,与合理施肥相结合得出一套因土、因苗、因时制宜,浅、湿、于灵活调节,促、控、养结合的优化灌溉技术,提高了水的利用效率。
With the method of combining applied research with foundamental theoretical study, the relationship between water-requiring regulation and the yield was analysed quantitatively. Through the adjusting of soil moisture by means of optimized irrigation pattern and the adequate fertilizing, an optimized irrigation technology was developed which can link promoting or controlling the growth of rice together with soil nutrient by irrigating in line with soil properties, seedling eonditions and seedling stages of rice and regulating flexibly with shallow water, saturated soil or unsaturated. Thus, the efficiency of water usage was promoted.
