3种化学增氧剂对南方早稻产量形成的影响
Effects of three types of chemical oxygenators on growth and development of early rice
摘要
Abstract
[Objective]To investigate the efficacy and the effects of different types of chemical oxygenators on the growth,development and yield formation of early rice in the south area of China.[Method]By using pot experiments and taking waterlogging without adding oxygenators as the control(CK),a systematic study was conducted to monitor the growth and development and yield formation of early rice"Zhongjiazao17"and the characteristics of three oxygenators[sodium percarbonate(T1),calcium peroxide(T2),and urea peroxide(T3)].[Result]All oxygenators can increase the dissolved oxygen(DO)in the soil,but oxygen amount and duration are different,and they are also different in by-products,resulting in differences in pH,ultimately leading to differences in the yield of early rice in the south.All oxygenators can significantly increase the number and volume of adventitious roots,enhance α-NA root viability,and maintain a relatively high leaf SPAD value in the maturity stage.Compared to the CK,T1,T2 and T3 increased grain yield by 4.30%-5.32%,15.03%-18.10%and 10.82%-12.46%respectively.Although T1 produced great amount of oxygenation,it generated a large amount of H+,which led to a certain inhibition of the tillering of early rice and reduced the yield.Both T2 and T3 have promoting effects,and the difference in the degree of promotion led to the difference of the yield.[Conclusion]In conclusion,three chemical oxygenators all can enrich the rhizosphere oxygen content,enhance the vitality of root,delay the senescence of leaves,and finally increase the yield.Among them,calcium peroxide has the best effect and is most suitable for the early rice in the south.关键词
