一、培养高标准有机质的土壤是果树高产稳产优质的基石,也是用好PBO的前提条件。根据本人对本地区部分桃园土壤的观察,有80%以上的果园达不到2%标准有机质的要求,熟土不深,土壤板结,化肥施用量偏多,有机肥严重不足,桃子品质下降,桃树寿命不长,使用PBO的效果不好。因此,建议广大果农在使用PBO的同时,要开发有机肥源,争取有机肥施用量占全年施肥量的70%。
First, to cultivate high standard organic matter soil is the cornerstone of the high and stable yield and quality of fruit trees, and also a prerequisite for the good use of PBO. According to my observation of some Taoyuan soils in the region, more than 80% of the orchards fail to meet the requirements of 2% of the standard organic matter. There are not enough mature soils, soil compaction, excessive application of chemical fertilizers, serious shortage of organic fertilizer, poor peach quality, peach quality Tree life is not long, the effect of using PBO is not good. Therefore, it is recommended that the majority of farmers use PBO at the same time, to develop organic fertilizer sources, for the application of organic fertilizer accounted for 70% of the annual amount of fertilizer.
