Embodiment 1

[0015] The actual measured pH of Alkaline Bantu is 9.06, and the content of soluble salts is 1.812%. Take out the extremely salinized soil on the alkali spot according to the bed width of 1m and deep plow 60cm, use a compactor to suppress the bottom to make the bottom soil layer flat, and spray the ratio of 55 parts of polyacrylic acid solution, 25 parts of wood vinegar, Soil film-forming agent with 20 parts of water; mix the taken out saline-alkali soil and sandy soil at a ratio of 2:1, and the spraying ratio is 5 parts of polyacrylic acid, 35 parts of inorganic acid, 0.1 part of plant hormone, and the balance is water Reduce salinity so that the soil pH reaches 6.5 and the soluble salt content is 0.2%; then transplant the annual cutting poplar seedlings in the nursery to the improved soil, and plant them at a plant spacing of 25cm and a row spacing of 50cm; then use sand to make a 20cm wide bed around the bed. , a cofferdam with a height of 15cm, and spray soil film-forming ...

Embodiment 2

[0017] The measured pH of the Alkaline Spots = 10.50, and the soluble salt content = 1.48%. Take out the extremely salinized soil on the alkali spot according to the bed width of 1m and deep plow 60cm, and use a compactor to suppress the bottom to make the bottom soil layer flat, and lay plant tar paper; take out the saline-alkali soil and sand according to the ratio of 2:1. The ratio is mixed, the spraying ratio is 5 parts of polyacrylic acid, 35 parts of inorganic acid, 0.1 part of plant hormone, and the balance is the reduction of salinity and alkalinity of water so that the soil pH reaches 6.8 and the soluble salt content is 0.17%; then the annual cuttings in the nursery Poplar saplings are transplanted in the improved soil, planted by plant spacing 25cm, row spacing 50cm; then use sand to make a wide 20cm, high 15cm cofferdam around the bed, and spray soil film-forming agent to fix the sand; finally use pH= Irrigate with 5.5-7.0% water to make the bed soil saturated.

Abstract

The invention relates to a method for using alkali soil as bed to plant poplar, which comprises testing the soil parameters, finishing soil, improving soil, transplanting, banking, and irrigating. Wherein, the invention is characterized in that: the pH of alkali lank is higher than 9, the soluble salt content is higher than 0.6%; it uses plant oil tart or oil filming agent to avoid soil deposit layer alkali into improved layer via capillary; the improved layer is functioned via soil alkali reducer to reduce salt and alkali; and it uses neutralized sand to improve the porous structure and penetration, and the anaerobic decomposed of reducer can supply nourishments to poplar. The invention can utilize alkali land and enlarge the plant area.

Description

Technical field: [0001] The invention relates to a method for planting poplars on saline-alkali soils as beds, in particular to a method for cultivating poplars on alkali patches of extremely saline-alkali soils with high pH and soluble salt content. Background technique: [0002] The threat of soil salinization to agriculture is a global problem, with about 1 billion hectares of 2 The saline-alkali land occupies nearly 25% of the land area. 20% of the world's arable land and nearly half of the irrigated land are threatened by varying degrees of salt damage. my country has only 100 million hm of arable land 2 , of which more than 20 million hm 2 For salt wasteland and 0.067 billion hm 2 It is a saline-alkali soil land, and it is one of the world's largest countries with saline-alkali land. my country is a large agricultural country, and agricultural development is one of the important components of national economic development. Studying effective measures to control s...
