不同的气象条件下对大豆施肥水平的研究

The Research of Fertilizer's Level of Soybean under Various Climate's Types

黑龙江省是我国大豆的主要产区，研究施肥对产量的影响可以加强对大豆生产的指导．本文运用所建立的大豆产量模型与降水型模型，采用频数分析法，求出在不同的气候类型下（丰年、平年、欠年），为了使大豆的单产达到某一水平，所需的各种肥料投入量的95%置信区间．这对于根据不同气候类型，在年初计划大豆的生产规模、各种肥料的投入量，安排农业生产都具有实用价值．

Hei Longjiang Province is the main producting area of soybean in our country,the reserach of fertilizer's influence to yield can strengthen the instruction of soybean's yield.The article defines 95% fiducial interval of needed fertilizers that can make the yield of climates (good year,average year,lean year)by applying the founded models of soybean's yield and precipitation,adopting the method of frequency number analysis.This has practical value of planning the producting scale,applying various fertilizers,preparing agricultcultural product under the various climate's types at the beginning of the year.
