本实验根据B_9在土豆叶面喷洒的规定,对叶面喷洒B_9的土豆与叶面不喷洒B_9的土豆进行了对比观测,且采用中国农科院关于科技成果效益计算方法从新增产量、新增产值、新增生产费用、新增纯收益、新增投资收益率等方面进行了经济效益分析,实验结果经济效益比较显著。
According to the regulations of B_9 sprayed on the leaves of potato, B_9 potato was sprayed on the foliage and the potatoes without spraying B_9 on the foliage were observed and compared. According to the calculation method of benefit of scientific and technological achievements of Chinese Academy of Agricultural Sciences, Increase production value, new production costs, new net income, new investment return rate and other aspects of the economic benefit analysis, the experimental results more significant economic benefits.
