潴育土马铃薯“3414”肥效试验OA
Experiment on ＂3414＂ fertilizer efficiency to potato in waterloggogenic soil in Zhao＇ an
采用“3414”肥料效应设计方案，研究了不同氮磷钾肥配比对马铃薯产量的影响，并获得肥料效应模型及该地力条件下的最佳经济施肥量，即每667m^2施N9．59kg、P20，1．19kg、K2O12．37kg，最佳经济产量为1524．2kg。
The effects of different combination ratios of N, P and K fertilizer on yield of potato were studied by using the efficiency-testing design for ＂3414＂ fertilizer. In the result, the fertilizer efficiency models and the quantity of optimum economic fertilization in the local soil fertility were gained in this paper. The optimum economic yield of potato per 667m^2 was 1 524.2 kg（22 863.0 kg/hm^2 ） when the application rate of N, P205 and K20 were 9.59, 1.19 an…查看全部>>
