Abstract

The invention discloses a pinus massoniana under-forest soil ammonium nitrogen and nitrate nitrogen in-situ culture method, which comprises a culture tube and a connecting tube, the bottom end of the connecting tube is vertically inserted in the top end of a base, the base is of a circular plate-shaped structure, and the top end of the base is fixedly connected with an electric heating tube. The top end of the base is further fixedly connected with a socket used for installing water injection pipes, the multiple electric heating pipes and the multiple water injection pipes are arranged, pouring holes are formed in the outer sides of the water injection pipes, the top ends of the water injection pipes are in threaded connection with sealing covers, and the two sides of the lower portion of each culture pipe are fixedly connected with a soil enzyme containing box and a soil microorganism containing box respectively. A soil temperature sensor and a soil humidity sensor are fixedly connected to the two sides of the lower portion of the culture tube respectively and electrically connected with the display device. The temperature and microorganisms in the soil can be increased, the moisture in the soil can be improved, and the formation of the content of ammonium nitrogen and nitrate nitrogen in the soil can be promoted.

Description

technical field [0001] The invention relates to the technical field of soil ammonium nitrogen and nitrate nitrogen cultivation methods, in particular to an in-situ cultivation method for soil ammonium nitrogen and nitrate nitrogen contents under a Pinus massoniana forest. Background technique [0002] Nitrogen exists widely in nature. It is the mineral element that plants absorb most from the soil and is also one of the most easily depleted nutrients. 98% of nitrogen (N) in nature is mainly concentrated in the geosphere, which is the largest nitrogen pool. Nitrogen (N) plays an irreplaceable role in plant growth, is an essential element for the synthesis of proteins and nucleic acids in plants, and is also involved in plant signal transmission. Plants can only absorb inorganic nitrogen such as ammonium nitrogen and nitrate nitrogen from the soil to maintain growth and development. However, more than 90% of the nitrogen in the soil is organic nitrogen. Therefore, soil nitroge...
