一、果园土壤调查抽样技术为了制定合理的施肥方案,就必须了解某块地段的土壤肥力高低与变异性的大小,因而在果树科研工作中常常需要作土壤调查分析。进行土壤取样时,除了要考虑土壤肥力本身的不均匀性外,还应考虑距果树根群的不同部位与施肥沟的距离、土壤层次、以及其它自然或 First, the soil sampling in orchard survey In order to develop a reasonable program of fertilization, we must understand the level of soil fertility and variability in a lot of land, and therefore often need to do research work in the fruit tree soil analysis. Soil sampling, in addition to consider the uneven soil fertility itself, but also should consider the different parts of the root tree from the ditch and fertilization ditch distance, soil levels, as well as other natural or
