摘要
在湖北利川市两个不同海拔高度的点上试验北京雷力海洋生物新产业股份有限公司生产的中量元素肥料（水剂）在水稻上的应用效果，增产增收显著，增幅6.63%～10.92%，可增产稻谷292.5～505.5 kg/hm2、增收877.5～1516.5元、净增收783～1422元；增加的产出投入比在8.29～15.05之间，水稻增产主要来源于结实率和千粒重提高，且前者作用明显大于后者，该肥可以在利川及相似区域大面积推广。
On basis of tests in regions with different elevations, rice sprayed with secondary nutrient fertilizers （×1 000） produced by Beijing Leili Group would signifi-cantly increase yield and incomes, which can be widely applied in Lichuan City or similar areas. With the fertilizer applied, rice yield can be improved by 292.5-505.5 kg/hm2, with increase of 6.63%-10.92%; farmer’s incomes can be enhanced by 877.5-1 516.5 yuan/hm2, with net income growth of 783-1 422 yuan; output-to-input rate kept in 8.29-15.05. The increased rice yield is mainly contributed by the in-creases of setting percentage and thousand-seed weight, of which the former＇s role is more significant. Hence, the fertilizer can be widely applied in Lichuan and similar regions.
