玉米“3414”肥料效应试验及推荐施肥分析

The "3414" Fertilizer Effect Trail of Maize and Analysis of the Optimal Fertilization Amounts

通过进行玉米"3414"肥料效应试验建立玉米施肥量与产量的回归方程,求出最佳施肥量;同时分析在最大产量和最佳产量推荐的施肥情况下,土壤养分的盈亏状况,并根据分析结果对试验推荐施肥量进行了评价。

Establish the regression equation of maize fertilizer effect was established on the base of ＂3414＂ trail and the optimal fertilization amounts was selected. Furthermore, the optimal fertilization amounts was evaluated after analyzing the potential balance of nutrients in the soil with the highest yield and the most efficiency yield.
