近年来,每当夏收和秋收之后,不少人为了省工省力尽快地赶种下茬作物,便把上茬作物的秸秆在田里烧掉。这不仅浪费了大量的能源和肥源,还污染了环境,危及人体健康;特别是对土壤的危害是严重和长远的,应该引起我们足够的重视。一、对土壤微生物的影响。大家知道土壤中有许多细菌、放线菌、真菌等微生物,他们积极地参加土壤有机物的分解、转化、氧化还原性的氮化物和固定空气中的氮素,合成腐殖质及微生素,抗菌素等。通过他们的活动可不断提高土壤肥力。
In recent years, whenever the summer harvest and the autumn harvest, many people rush to plant the crops as soon as possible to save labor and labor, they have burned the stalks of the stubble crops in the fields. This not only wastes a lot of energy and fertilizer sources, but also pollutes the environment and endangers human health. In particular, the harm to the soil is serious and long-term, which deserves our due attention. First, the impact on soil microorganisms. We all know that there are many bacteria in the soil, actinomycetes, fungi and other microorganisms, they actively participate in the decomposition of soil organic matter, conversion of nitrogen oxides and nitrogen fixation in the air, the synthesis of humus and microbes, antibiotics, etc. . Through their activities can continue to improve soil fertility.
