【摘要】 选用经过特殊处理的两种添加剂为节水材料,采用团粒法复混肥生产工艺技术研制出的抗旱复混肥(N11%,P2O56%,K2O8%,质量分数)在生产中解决了节水材料与复混肥相给合的问题。大田试验结果显示,与等养分普通复混肥相比,该产品可使玉米增产17.6%,增收2027元/hm2。更多还原

【Abstract】 Two specially treated additives are chosen as water-economizing materials,a drought-resistant compound fertilizer (N 11%,P2O5 6%,K2O 8%,in mass fraction) is developed by agglomeration,and in the production the problem of binding the additives with the fertilizer is solved. The field tests of this product as compared to the common compound fertilizer of equal nutrient content give remarkable results,increasing the yield of corn by 17.6% and the income by 2 027 yuan RMB/hm2.更多还原
