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877.5~1 516.5元、净增收783~1 422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。
In Lichuan City, Hubei Province at two different altitudes test Beijing Leroy Marine Biotechnology Co., Ltd. production of medium-sized elemental fertilizer (water agent) in the application of the effect of rice, increase production and income significantly, an increase of 6.63% to 10.92% , Increased rice yield by 292.5 ~ 505.5 kg / hm2, increased incomes by 877.5 ~ 11 516.5 yuan and net income increased by 783 ~ 1222 yuan. Increased output-to-input ratio was between 8.29 and 15.05. Rice yield mainly came from seed setting rate and grain weight increase, The effect of the former is obviously greater than that of the latter.
