Effects of silicon,calcium on growth and yield of the peanut variety Zhengnonghua 9
Abstract
Study on silicon,calcium and magnesium fertilizers for growth and yield of peanut variety Zhengnonghua 9 showed that three fertilizer could make the peanut stem stout,vigorous growth,resistance enhanced,the incidence of disease reduce;Silicon calcium and magnesium fertilizer resorted to early seedling stage 2 day,germination rate,the number of results was superior to calcium fertilizers and plant efficiency silicon.All processing pod yield increased 41.7~717.0 kg / hm2.The yield increased 0.85%~14.7%.Calcium peanut yield components for the greatest impact,first on the longest average length of lateral branches,full fruit number per plant on average 11.15,the average berry weight 273.25 g,one hundred kernel weight 117.25 g.Rice yield and plant full the number were highest,and the average yield calcium was 5 386.01 kg.The three treatment increased significantly.The average yield of silicon calcium and magnesium fertilizer was 5 260.95 kg.The two treatment increased significantly.The average yield 5 190.08 kg efficient silicon fertilizer.A combination of calcium influenced significantly higher and more reliable than calcium-free fertilizers on the yield and composition of fertilizers.
