Problems solved by technology

The harm of saline-alkali land to soil and plants is mainly manifested in: first, increasing the osmotic pressure of the soil solution, so that the plant roots cannot absorb water from the soil solution, but the water will seep out; second, destroying the soil structure, resulting in highly dispersed soil particles, affecting The normal growth of seedlings unearthed and rhizomes; third, the existence of a large number of certain chloride ions and sodium ions in saline-alkali land inhibits calcium, phosphorus, iron, etc. from entering the plant, causing the imbalance of plant mineral nutrition
[0003] The usual way to control soil salinity is to wash the soil with a certain amount of water, but washing requires a lot of fresh water, which not only causes a lot of waste of fresh water, but also increases the cost of planting, and it is more difficult to implement in areas where fresh water is relatively scarce.

Embodiment 1

[0020] A high-efficiency irrigation and cultivation method for Chinese prickly ash in heavy saline-alkali land, comprising: the steps of seed treatment, seedling management, and cultivation management, specifically:

[0021] ① Seed treatment: collect fully mature and plump fruits from Dahongpao trees with pure varieties, strong growth, and no pests and diseases at an altitude of 1100m. After drying in the shade, remove the peel and separate clean seeds with full kernels. In the glass tank, use sodium hydroxide solution with a mass concentration of 2.0%, 2.5%, 3.0%, and 3.5% for gradient soaking, and the soaking time for each concentration is 60min, 40min, 20min, and 10min. Rinse the seeds and set aside;

[0022] ② Seedling management: Mix the pepper seeds and river sand evenly according to the weight ratio of 1:5, put them in cloth bags, each cloth bag is 1kg, place it at a temperature of 45°C for 2 days, and use a mass concentration of 3.5% cumin extract After spraying, even...

Abstract

The invention discloses an efficient irrigation and cultivation method of Sichuan pepper in heavy saline-alkali soil and belongs to the technical field of saline-alkali soil treatment and crop planting, in order to solve the problem of barriers of Sichuan pepper planting in heavy saline-alkali soil. According to the method, through the steps of seed treatment, seedling culture treatment and cultivation management, nutrition needed for Sichuan pepper growth is assured, besides, soil of heavy saline-alkali soil is improved, survival rate of Sichuan pepper seedlings is guaranteed effectively, survival rate of Sichuan pepper cultivated in heavy saline-alkali soil is increased, yield of Sichuan pepper is increased, Sichuan pepper planting range is enlarged effectively, and obstacles of planting Sichuan pepper in saline-alkali soil are broken through.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil control and crop planting, in particular to a high-efficiency irrigation and cultivation method for prickly ash in heavy saline-alkali land. Background technique [0002] Saline-alkali land is an important land resource for agricultural development and utilization. It is generally believed that when the accumulation of water-soluble salts in the soil surface or subsurface exceeds 0.2%, it belongs to the category of saline-alkali land. The harm of saline-alkali land to soil and plants is mainly manifested in: first, increasing the osmotic pressure of the soil solution, so that the plant roots cannot absorb water from the soil solution, but the water will seep out; second, destroying the soil structure, resulting in highly dispersed soil particles, affecting The normal growth of seedlings unearthed and rhizomes; third, the presence of a large number of certain chloride ions and sodium io...
