1982年秋至1983年冬我们地区土肥站在南京土壤研究所及广西农学院土化系的协助下,对桂中北灵川、临桂、兴安、全州四个柑桔基地县的主要柑桔果园土壤进行了一次较全面的土壤考察。取回了45个果园的剖面样36个、农化样53个,其中微景元素分析样87个。主要分析土壤酸碱度、有机质、全氮、全磷、全钾、速效钾代换量以及锌、硼、钼、钻、铁、锰等微量元素。一、常量养分状况(见表一)1、土壤酸碱度:据分析灵川、兴安、临桂三县26个果园混合样中,pH 值大于6的果园占19.23%,pH6以下的果园占
From the fall of 1982 to the winter of 1983, with the assistance of Nanjing Institute of Soil Science and the Department of Soil Science of Guangxi College of Agriculture, soil fertility stations in our area were mainly cultivated on the main citrus fruits of four citrus bases in Lingchuan, Lingui, Xing’an and Quanzhou Orchard soil for a more comprehensive soil investigation. 36 sections of 45 orchards were retrieved and 53 were agro-chemical samples, of which 87 were micro-elemental analysis. Mainly analyzed soil pH, organic matter, total nitrogen, total phosphorus, total potassium, available potassium substitution and zinc, boron, molybdenum, diamond, iron, manganese and other trace elements. 1, nutrient status (see Table 1) 1, soil pH: According to analysis Lingchuan, Xing’an, Lingui three orchards of 26 mixed samples, the pH value of 6 or more accounted for 19.23% of the orchards, pH6 or less accounted for
