种植在红、黄壤丘陵山地的柑桔往往单低产,品质劣,盛产后易衰败。为改变不利的生态环境,我们对山地红壤柑桔进行较大面积的高产稳产优质培育试验,探讨高产土壤肥力指标,单位面积结果水平与土壤营养供养指标及其培育途径,并作系统的定位鉴测,现将1982—1986年五年间的试验结果整理如下。
Oranges planted in red, yellow soil hilly mountain often single low-yield, poor quality, easy to decline after the rich. In order to change unfavorable ecological environment, we conducted a large-area, high-yielding and high-yielding cultivation experiment on red soil citrus in mountainous area to investigate the index of high yield soil fertility, the result of unit area and the index of soil nutrient supply and their cultivation ways, Test, now 1982-1986 five years of test results are summarized below.
