根据国家标准,利用滤泥研制甘蔗有机-无机复混肥料配方组合为:w(有机质)≥20%,总养分w(N+P2O5+K2O)≥20%,配比为9-4-7。并用该肥与25%复混肥料和常规施肥进行了田间肥效对比试验。
According to the national standard, the formula of organic-inorganic compound fertilizer for sugarcane was developed according to the national standard: w (organic matter) ≥20%, total nutrient w (N + P2O5 + K2O) ≥20% and the ratio of 9-4-7. And with the fertilizer and 25% compound fertilizer and conventional fertilization field fertilizer efficiency comparison test.
