特贝钙土壤调理剂对花生产量及土壤pH值的影响

The Effect of Soil Conditioner Tebeigai on Peanut Yield and Soil pH Value

为探讨特贝钙土壤调理剂对花生产量的影响及土壤酸化的改良效果,进行特贝钙土壤调理剂在花生上的应用效果试验,结果表明:与习惯施肥相比,增施特贝钙土壤调理剂不仅能改善花生主要性状,显著提高花生产量,且能改良土壤酸化。其中以习惯施肥+特贝钙土壤调理剂3 000 kg·hm^(-2)的效果最好,花生产量极显著高于习惯施肥,增产率为12.73%,花生平均单株饱果数、饱果率、单株果重及百果重分别增加1.5个、1.6个百分点、3.5 g、7.8 g,并显著提高花生收获后耕层土壤的pH值,比习惯施肥增加0.36。

In order to study the effect of soil conditioner Tebeigai on peanut yield and the improvement effect of soil acidification,the application effect on peanut was tested.The results showed that compared with conventional fertilization,the application of soil conditioner Tebeigai could not only improve the main characteristics of peanut,but also significantly increase peanut yield,and improve soil acidification.The effect of 3 000 kg·hm-2 Tebeigai was the best.Peanut yield was significantly higher than that of conventional fertilization,with an increase rate of 12.73%.The average number of full fruits per plant,full fruits per plant,fruit weight per plant and 100 fruit weight of peanut increased by 1.5,1.6 percent point,3.5 g and 7.8 g,respectively.At the same time,the soil pH value of cultivated layer after peanut harvest was significantly increased by 0.36,comparing with conventional fertilization.
