施加玄武岩对小麦生长和籽粒干重的影响
The effect of basalt application on wheat growth and the grain dry weight
摘要
Abstract
In order to study the effect of basalt on crop growth and dry weight of grains,we investigated the effects of applying basalt powder with different grain sizes(coarse particle size＜1000 μm,fine particle size＜100 μm,applied amount 5 kg·m-2)to agricultural soils under greenhouse conditions on the dry weight of wheat grains,and on the content of the major elements(K,Ca,Mg)in wheat organs at different growth stages and potential soil exchangeable cations.The results showed that the application of basalt powder could promote the growth of wheat plants(especially leaves and spikes)and increase the dry weight of grains.During the entire stage of wheat growth,there was no significant change in the content of single major elements in wheat organs,but the content of K,Ca,Mg in wheat plants increased with wheat growth,and the effect of applying basalt was more significant(P＜0.01).The application of basalt did not increase the total amount of potential exchangeable ions in the soil(P＜0.01).This study shows that the application of basalt powder increases the dry weight of wheat grains,promotes wheat growth,and improves wheat quality.关键词
