花生在生长期间(盛花期和结英期)喷施多元螯合微肥,能提高叶面积系数,促进光合作用,改善植株的营养状况,增加单株结果数,协调地上、地下养分分配,使后期养分较多地转向英果,促进英果充实,提高双仁率、饱果率和经济系数。但是由于螫合微肥中各元素的配方不同,喷施后对花生性状的促进作用也有所不同。 Spraying the multi-chelated trace fertilizers during the growth period (full-bloom stage and node-ending stage) can improve the leaf area coefficient, promote the photosynthesis, improve the nutritional status of the plant, increase the number of fruit per plant, coordinate the distribution of nutrients on the ground and the ground, Late nutrients more fruit turned to the British, to promote fruit fullness, improve double kernel rate, full fruit rate and economic coefficient. However, due to the different formula of each element in the compound fertilizer, the promotion effect on the peanut properties after the spraying is also different.
