Analysis on the High-yield Fertilizer and Water Application Technology of Single Cropping Hybrid Rice in the Riparian Rice Region of Anhui

[Objective] The aim was to popularize the highyield and high-efficiency cultivation technology of rice and promote agricultural sustainable development.[Method] The high-yield fertilizer and water application model of rice were suggested through developing the demonstration of fertilizer and water application in high-yield cultivation technology of hybrid rice in the riparian rice region of Anhui.[Result] The average yield of tested single cropping hybrid rice was 10 575 kg/hm2.The tested seedlings grew robustly,their tillers and green leaves per plant were many,their root systems were relatively shallow,their main stems were flat and their base widths were moderate,their secondary tillering rates were high,their synchronous development of leaves and tillers was good and the dry matter accumulated in them was much.The tested rice individuals grew well and had many root systems grown out and their stem bases were stocky.The field crop closure stage of tested rice populations was delayed and their aeration and light transmission were good.The plastochron between initial heading and full heading of tested rice was 2-3 d,and their headings were basically simultaneous,there were many panicles on the main stem,the total glumous flowers per panicle developed adequately and their relative proportionality was better.The proportion of dry matter transferred into panicles in filling and fruiting stage was high and the dry matter accumulated in milk stage accounted for more than 60% of theoretical yield accumulation.[Conclusion] The research layed a good foundation for the high-yield cultivation of single cropping hybrid rice in in the riparian rice region of Anhui.
