Effect Of Wheat Straw Wood Vineger On Grain Yield And Qualities Of Rice

Wood vinegar,as a natural agricultural material,is used more and more extensively on agricultural field.However,the study of wood vinegar to the rice output and quality needs further research.In this paper,three rice, Yujing8,ZhongZhiyou2004 and Huangyou520 were treated with different concentrations of wheat straw wood vinegar. It investigated the influence of wood vinegar on the output and quality of rice .The reshlts are as folloes:1. In the growth and strong period of rice,we managed rice using different wood vinegar which were diluted 400 times,600 times,800 times and 1000times.We determined plant height,panicle length,unit strains, 1000-grain weight and so on.As a result,it is good for Yugeng8 and Zhongzhiyou2004.It increase plant height,panicle length,unit strains, 1000-grain weight of rice.It is best for rice which managed by wood vinegar of 600 times.The effects of wood vinegar on rice were various with different concentration and there were different between varieties.But the effects of wood vinegar on rice were restrained with 400 times concentration,other concentrations were good for plant height,spike length,unit strains, 1000-grain weight of rice.2. we managed rice using different wood vinegar which were diluted 400 times,600 times,800 times and 1000times.There were improving to varying degrees in processing quality,appearance quality,natritionalquality,cooking and eating quality from Yugeng8 and ZhongZhiyou2004. The effects of wheat straw wood vinegar on rice were restrained with 400 times concentration,so there were some of effecting on rice quality.Other different wood vinegar promote the quality of rice.
