植物活力久久对马铃薯产量及产量性状的影响

目的]研究植物活力久久对马铃薯产量及产量性状的影响,为该肥料的大面积推广应用提供科学依据。方法]通过小区试验和田间示范试验,研究植物活力久久对马铃薯产量和产量性状的影响。结果]小区试验结果显示,与喷施磷酸二氢钾相比,喷施植物活力久久增产3 672.0 kg/hm~2,增产率为10.73%,增收3 672.0元/hm~2。大田示范结果显示,与喷施磷酸二氢钾相比,喷施植物活力久久增产3 352.5 kg/hm~2,增产率为5.82%,增收3 352.5元/hm~2。结论]植物活力久久对马铃薯产量有显著影响,且主要是增加了单株结薯数、单株薯重和商品率。

Effects of the Long Plant Vigor on the Yield and Yield Character of Potatoes

Objective] To study effects of the long plant vigor on yield characters,yield and commercial rate of potatoes in order to provide the scientific evidence for widespread popularization and application of the fertilizer.Method] By setting potassium dihydrogen phosphate as control,effects of the long plant vigor on yield and yield characters of potatoes were investigated through plot experiment and field demonstration experiment.Result] The results of field plot trails showed the increment of yield was 3 672.0 kg/hm2,the rate of growth was 10.73％,and the new additional revenue was 3 672.0 yuan/hm2 respectively compared with applying potassium dihydrogen phosphate,while the results of field demonstration showed that the increment of yield was 3 352.5 kg/hm2,the rate of growth was 5.82％,and the new additional revenue was 3 352.5 yuan/hm2,respectively compared with applying potassium dihydrogen phosphate.Conclusion] The long plant vigor has obvious effect on the yield of potatoes,and mainly increases the fruit number per individual plant,signal fruit weight and commercial rate.
