1986年江门甘蔗化工厂农务科与轻工业部甘蔗糖业科学研究所协作进行因土配方施肥技术验证和示范。结果证实了因土配方施肥是甘蔗科学合理的施肥技术。与当地习惯的施肥方法比较:它能节省肥料成本——每亩成本仅30～40元,节省了5～15元;并能明显增加甘蔗产量——亩增产1～1.5吨,增幅达17～32%;大大提高蔗农的经济收益——亩增收57～89元;增加工厂税利——亩增36～58元。与高量配施肥料的施肥方法比较:它能大大地节省肥料成本——每亩节约57～66元;而产量差异不大,仍呈略增趋向——亩仅减0.125吨至亩增0.458吨;蔗农经济收益明显而稳定——亩增63～84元;但对工厂税利基本无影响——亩减10元至亩增8元。
In 1986 Jiangmen sugar cane chemical plant agricultural and sugar cane Institute of Science and Technology Ministry of Light Industry collaborative soil fertilization technology validation and demonstration. The results confirmed that fertilization due to soil formula is sugarcane science and reasonable fertilization technology. Compared with the local manners of fertilization: It can save the cost of fertilizer - the cost per mu is only 30-40 yuan, saving 5-15 yuan; and can significantly increase the output of sugar cane - increase production of 1 ~ 1.5 tons, an increase of 17 ~ 32%; greatly enhance the economic benefits of sugarcane farmers - acres of income 57 to 89 yuan; increase the factory tax profits - acres by 36 to 58 yuan. Compared with the fertilization method with high amount of fertilizer: it can greatly save the cost of fertilizer - saving 57 ~ 66 yuan per mu; while yield is little difference, it still shows a slight increase trend - only reduce 0.125 tons of mu to 0.458 mu Ton; cane farmers obvious and stable economic benefits - increased by 63 to 84 yuan mu; but the factory tax profit basically no effect - mu minus 10 yuan to increase by 8 yuan.
