Abstract

Abstract: In order to provide some scientific basis for disaster relief of early rice after flood disaster in Hunan province, the biological characteristics and relief benefits of early rice of ratooning rice after flood disaster were studied by cutting panicles (20cm) in Zhuzhou country in 2016. The experiment by using the Lingliangyou 211 of hybrid early rice and Zhongzao 39 of conventional early rice as materials, and set cutting panicles as treatment at heading stage, by using the uncutting panicles as control. The results showed that the grain yield of Lingliangyou 211 with cutting panicles was 6.4% higher than that of the Zhongzao 39, the grain yield of Lingliangyou 211 with cutting panicles increased significantly (P<0.01) by 115.4% and 125.0% compared with the control, respectively. And the rice appearance quality and processing quality of cutting panicles treatments was better significantly (P<0.05) than that of the control. Ratooning rice by cutting panicles treatments appeared the crop growth rate of plant, net assimilation rate of leaves, SPAD value of leaves, net photosynthetic rate of leaves, stomatal conductance and transpiration rate of leaves were greater with cutting panicles treatments than that of the control at full heading stage, and the leaf with cutting panicles treatments showed normal discoloration at maturity stage. Meanwhile, the growth period of rice with cutting panicles treatments was shorter than that of the control. The input and output ratio of rice with cutting panicles treatment increased 117.1% and economic reduced 57.3% compared with the control. Therefore, it was had higher economic yield, lower farmers loss and significant disaster relief benefits by cutting panicles after flood disaster, which was suitable for popularization and application in Hunan province flood prone areas.
