贵州主栽水稻品种不同成熟期稻草与稻谷产量和品质分析
Study on Yield and Quality of Rice and Its Straw in Different Maturity Stage
摘要
Abstract
[Objective] In order to make better use of the straw resources,improve the utilization ratio as feed.[Method] Six rice varieties were selected as materials,the yield and quality of rice grain and straw were analyzed and compared in deferent maturity stages.[Result] The results showed that the output of rice with the ripening time overall performance for the first and then decreased,in milk,ripening,mature,mature four period to mature period the highest yield.While the straw yield at maturity for the first performance after descending ascending trend,in the grain yield was the highest point of straw yield the lowest.Six varieties of rice three quality indicators in different mature period basically are shown as the first increasing and then decreasing trend,each quality index in the later stage,while in the later decline.Straw with the increase of maturity of its crude fiber content showed a rising trend,leading to its feeding quality decline,and most of the results of class.But late in the crude fiber content of substantially constant,and the appearance is different with corn.[Conclusion] In view of the value and the value of rice straw huge differences,only from the economic yield,the appropriate rice harvest period is mature period.A comprehensive reference of straw and paddy yield in milk ripe stage total output is the highest.关键词
