目前,我省果园多数土壤肥力差,有机质含量常在0.5%以下。由于有机质含量低,直接影响了矿质营养元素的含量。多数果园表现幼龄期(4—10年生)结果晚、产量低;成龄果园产量不高不稳,即大小年结果严重,品质低劣。造成这些原因虽与各方面因素有关,但与土壤管理、不能适时适量增施有机肥料有着密切关系。据山东省费县山楂幼树密植丰产试验介绍,该园栽植第五年亩产达到5,459斤。措施之一就是注重土壤管理,栽前大坑亩施有机
At present, most of the orchards in our province have poor soil fertility and the organic matter content is often below 0.5%. Due to the low content of organic matter, it directly affects the content of mineral nutrients. Most orchards show young age (4-10 years old) late results, low yield; mature orchards yield is not high and unstable, that the size of the year results are serious, poor quality. Although these causes are related to various factors, it is closely related to the soil management and the improper application of organic fertilizers in due course. According to Shandong Province Fei County hawthorn seedlings close planting high yield test, the park planted the fifth year yield reached 5,459 pounds. One of the measures is to focus on soil management, before planting Tai Hang Mushu organic
