福建霞浦县马铃薯“3414”肥效试验初报OA
Preliminary report on the fertilizer efficiency experiment ＂3414＂ of potato in Xiapu County, Fujian Province
在霞浦县沙江镇进行马铃薯“3414”肥效试验表明，N、P、K肥均影响马铃薯产量，且N肥对产量的影响较P、K肥大；通过建立回归方程并对其进行分析，马铃薯产量与N、P、K施肥量之间存在极显著的三元二次回归关系；N、P、K肥施用量分别为201．12、40．78、324．16ks·hm^-2，则马铃薯经济产量达最高，为34069．89kg·hm^-2；N、P、K肥施用量分别为191．80、44．42、285．55kg·hm^-2，则马铃薯施肥经济效益达最…查看全部>>
Fertilizer efficiency experiment＂ 3414＂ of potato in particular experimental conditions showed that nitrogen, phosphorus and potassium fertilizers influenced the yield of potato, and nitrogen fertilizer had more effect than phosphorus and potassium fertiliz- ers. Through establishing and analyzing the regression equation, it was discovered that there was an extremely significant ternary quadratic regression rehtion between potato yield and the fertilizing am…查看全部>>
