近日,来自法国、印度的科学家在北京向人们介绍了他们合作研究完成的“利用蚯蚓作用的有机培肥技术”。 蚯蚓可以提高土壤肥力,增加作物产量。蚯蚓的排泄物中富含可培肥土壤的无机营养元素和腐殖质,能在根系附近释放植物生长所需的营养物质,蚯蚓还可以改变土壤的物理结构,同时还可以促进与根系共生的菌根真菌在根上定植,而这种菌根可以帮助根系吸收水分和氨、磷及其他营养。 此外,蚯蚓可以控制寄生性线虫的群体,蚯蚓活跃时线虫数目减少。在肥力较低的土壤中蚯蚓的作用尤为明显,因此科学家认为有必要研发一种技术来促进蚯蚓的活 Recently, scientists from France and India introduced the “Organic Fertilization Technology Using Earthworms” completed by their cooperative research in Beijing. Earthworms increase soil fertility and increase crop yields. Earthworm excrement is rich in inorganic nutrients and humus which can fertilize the soil and release nutrients required for plant growth near the root system. Earthworms can also change the physical structure of the soil and at the same time promote the mycorrhizal Fungi are colonized on the roots, and this mycorrhiza helps the roots absorb moisture and ammonia, phosphorus and other nutrients. In addition, earthworms control the population of parasitic nematodes and reduce the number of nematodes when earthworms are active. The role of earthworms in particularly fertile soils is particularly pronounced, and scientists consider it necessary to develop a technique to promote earthworm activity
