小麦穗期喷施叶面宝增产效应研究

本试验于小麦穗期用不同浓度叶面宝喷施叶片,通过测定生理指标和产量,结果表明100PPM叶面宝可显著增加叶片内叶绿素含量和光合速率,使小麦籽粒灌浆速率增强,灌浆时间延长,千粒重提高。单产比对照增加17.44％。小麦穗期喷施叶面宝是一项行之有效的增产措施。

Study on the Increasing Production Effect of Spraying YeMian Bao in Wheat

This experiment is done by using differnt concen-traHon of yemianbao to spray leaves during the heading period of wheat, throgh de-termiuinh the wheats physiological index and yield, the result shows that yemianbao (100PPM)can obriously improve the chlorophyll content and the photosynthesis rate within learesj by which the wheat seed can be prolnged the milking stage,and increased the filling rate.In this way,the weight of per 1000 kernel will raise. In contrast to per unit area yield, it increases 17.44 percent.According to this experiment,it is an effectire measure,for improring yield to spray yemianbao during the heading period of wheat.
