Rescue reagent for rejuvenation of Pinus tabulaeformis and application thereof

Abstract

The invention relates to a rescue reagent for rejuvenation of Pinus tabulaeformis and an application thereof. The rescue reagent for rejuvenation is prepared by mixing the following components: refined pyroligneous liquor, amino acid, peptidoglycan, potassium sulfate, sodium alpha-naphthyl acetate, ferrous sulphate, urea, and VC. The rescue reagent for rejuvenation has the advantages of environmental friendliness, simple technology, and low cost; during practical application, water can be added into the reagent for dilution, the dilution ratio is 3-10 times, and the solution is filled into an axial root part of a big tree.

Description

technical field [0001] The invention mainly relates to a Chinese pine rejuvenation rescue agent for improving the growth of Chinese pine by adjusting soil physical and chemical indicators to sterilize and supplement nutrients for the weak seedlings of Chinese pine that are sensitive to salt and alkali. Background technique [0002] Pinus tabulaeformis Carr. (Latin scientific name Pinus tabulaeformis Carr.) belongs to Pinaceae and Pinus, and is also known as short-leaved pine, short-leaved masson pine, red bark pine, and northeast black pine. It is native to China. Pinus tabulaeformis has a wide range of natural distribution, distributed in Liaoning, Jilin, Inner Mongolia, Hebei, Henan and other places. [0003] Pinus tabulaeformis is a positive tree species with shallow roots, light-loving, barren and wind-resistant, and can grow on acidic, neutral or calcareous loess with deep soil layers and good drainage at temperatures of -25°C. Pinus tabulaeformis likes acidic soil and...

Problems solved by technology

2) Toxicity of ions: Na in plant leaves + Excessive accumulation of common leaf tip and leaf edge scorch (sodium burn), and will inhibit the absorption of calcium, resulting in calcium deficiency in plants, difficult to pull out new leaves; Ca 2+ Excess may lead to lack of nutrients such as boron, iron, zinc, manganese; Mg 2+ Excessive amount will cause the leaf edge of the plant to scorch, resulting in potassium deficiency, and the tip and edge of the old leaves will start to turn green and yellow until they are scorched.

3) Extensive application of chemical alkaline fertilizers caused salt and Cl - Accumulated on the surface of the tree disk, resulting in the death of the root system on the surface, and at the same time, accompanied by spring irrigation and rainfall during the growing season, the salt ions move down, and the Cl around the main root system - Content and total salt content exceed the standard, resulting in more serious Cl - Poison and salt damage, followed by shrinkage of new shoots and death of the whole plant

In the liquid, no literature has been retrieved that uses wood vinegar as the main component to specifically relieve the pH increase of Chinese pine soil
