摘要
在水稻齐穗期 ,叶面喷施不同次数浓度为 1%的尿素溶液 ,研究对水稻结实及品质性状的影响。结果表明 :不同喷肥处理均有不同程度提高结实率 ,降低秕粒率 ,增加千粒重 ,改善稻谷碾磨品质的作用。不同处理的影响程度有差异 ,喷施 3次 1%尿素溶液的效果较好。叶面喷施尿素对稻米蒸煮品质及垩白的影响不显著。
At full heading time of rice,foliar fertilization was sprayed to study the response of fructificative capability and quality of rice.The main results are as follows:every treatment enhanced full\|grown grain rate,reduced blighted grain rate,increased the \{1 000\}\|kernel weight and improved the grinding quality of rice at different degree.The influences of different treatments are not identical.Influence of foliar fertilization on chalky and cooking quality of rice are not notable.
