近年来,我市弱筋小麦生产面积逐年扩大,而弱筋小麦后期施肥过多易导致籽粒面筋和蛋白质含量提高,减少肥料投入又易早衰。经多年试验,通过后期喷施叶面肥肥力宝,很大程度上缓和这一矛盾。2003年在省农林厅组织下,针对后期不同时期和不同浓度喷施肥力宝的效应作了进一步研究,结果不同时期和不同浓度喷施肥力宝均能不同程度提高产量,其中以孕穗期和齐穗期两次亩用50g效果最好。1试验设置1.1试验分设在孤山镇孤山村和靖城镇光明村两点,供试
In recent years, the production area of weak gluten wheat in our city has been expanding year by year. However, the excessive fertilization of weak gluten wheat in the late stage can easily lead to the increase of gluten and protein content in grains and reduce the input of fertilizers and premature aging. After many years of experiment, through the late spraying foliar fertility Po, to a large extent to ease this contradiction. In 2003, under the organization of the Provincial Department of Agriculture and Forestry, further studies were conducted on the effects of spraying fertilizers at different periods and in different concentrations in the later period. Results The results showed that fertilizers at different periods and different concentrations could all increase yield to varying degrees, Spike two times 50g with the best results. 1 Test Setup 1.1 The experiment is divided into two points in Gushan Village and Gumming Village, Gushan Town for test
