1987—1988年连续二年进行了甘蔗有机—无机肥料配施研究.结果表明,有机—无机肥配施对提高甘蔗的产量和品质都有良好的作用.甘蔗产量增加13.00—20.47%(平均16.31)%,蔗糖分提高0.33—3.68%(平均2.45%),有机—无机肥配施比单纯化肥配施效果更显著;有机—无机肥配施明显提高甘蔗对肥料氮磷钾的收改利用,对增加钾素的吸收利用尤为突出.因此,必须强调在施用有机肥料的基础上配合施用各种化肥,才是唯一正确的施肥措施.
The organic-inorganic fertilizer application of sugarcane was carried out for two consecutive years from 1987 to 1988. The results showed that organic-inorganic fertilizer had a good effect on improving the yield and quality of sugarcane.The output of sugarcane increased by 13.00-20.47% (average 16.31 ), Sucrose increased by 0.33-3.68% (average 2.45%), organic-inorganic fertilizer application was more significant than simple chemical compounding; organic-inorganic fertilizer application significantly improved the utilization of nitrogen, phosphorus and potassium fertilizers, Therefore, it is necessary to emphasize that it is the only proper fertilization measure to apply various chemical fertilizers based on the application of organic fertilizers.
