蚯蚓作为潜在的土壤生物资源和动物性蛋白的重要来源,已经引起人们的重视。目前我国已有27个省、市开展蚯蚓养殖利用的试验研究和生产,获得了可喜的成绩。在人工养殖利用中,除作为动物蛋白饲料之外,还应充分利用其改土增产的作用。据多年的研究表明,蚯蚓对土壤肥力的影响是比较全面的。主要表现在:加速土壤结构形成,促进土肥相融,加速有机质转化,提高植物营养,改善通透性能,提高蓄水、保肥能力。因此,养殖蚯蚓应和改土肥田结合起来。
As an important source of potential soil biological resources and animal proteins, earthworms have attracted people’s attention. At present, 27 provinces and cities in China have carried out pilot studies and production of earthworm farming and utilization, and obtained gratifying results. In the use of artificial breeding, in addition to animal protein as feed, but also make full use of its role in soil improvement yield. According to years of research shows that earthworms on the impact of soil fertility is more comprehensive. Mainly in: accelerating the formation of soil structure, promote the integration of soil and fertilizer, accelerate the conversion of organic matter, improve plant nutrition, improve permeability, improve water storage, fertilizer retention. Therefore, farming earthworms should be combined with soil amendments.
