玉米缓释专用肥,具有节能、环保、控失,多元素促进养分分层渗透吸收;养分流失少、利用率高,同时具有省工、省时、省力、省钱等特点。通过示范验证该肥料对玉米的增产增收效果,为大面积推广应用提供理论依据。1材料与方法1.1试验地点概况试验地点位于黑龙江八五四现代农业研发中心。试验地肥力中等、地势平坦、土壤为白浆土。0~20cm耕层土壤养分状况为:有机质58.213g/kg,水解性氮219mg/kg,有效磷33.15×10~(-6),速效钾131.4mg/kg,pH 5.67。
Corn slow release special fertilizer, with energy saving, environmental protection, control loss, multi-element to promote nutrient stratification infiltration and absorption; less nutrient loss, high utilization rate, at the same time saving workers, saving time, effort, money and so on. Through demonstration demonstration of the effect of fertilizer on corn yield and income, provide a theoretical basis for large-scale popularization and application. 1 Materials and Methods 1.1 Test Location Overview Test site is located in Heilongjiang eight five four modern agricultural R & D center. Fertility test medium, flat, soil is white soil. Soil nutrient status of 0-20 cm soil layer was 58.213 g / kg organic matter, 219 mg / kg hydrolyzable nitrogen, 33.15 × 10 -6 effective phosphorus, 131.4 mg / kg available potassium and pH 5.67.
