Embodiment 1

[0055] A kind of method for planting bonus on saline-alkali land, comprises the following steps:

[0056] (1) Phosphogypsum pretreatment: dry the phosphogypsum until its moisture content is 3%, then send it into a pulverizer for pulverization, and obtain phosphogypsum powder with a fineness of 60 mesh;

[0057] (2) Pretreatment of saline-alkali land: the planting site is the saline-alkali land of Haixing Bingjie Farm, and the total salt content of the topsoil at a depth of 0-20 cm is 0.25%. For a ditch with a width of 10 cm and a width of 20 cm, the distance between the ditch is 30 cm, and the phosphogypsum powder is evenly spread in the ditch and then filled with soil. 15cm, 14 days after covering the film, remove the film and perform leaching treatment;

[0058] (3) Soil preparation: Evenly apply compost and oily soil in the saline-alkali soil after processing in step (3), the application rates of compost and oily soil are respectively 800kg / mu and 500kg / mu, then carry out ...

Embodiment 2

[0064] A kind of method for planting bonus on saline-alkali land, comprises the following steps:

[0065] (1) Phosphogypsum pretreatment: after drying the phosphogypsum to a moisture content of 7%, it is sent into a pulverizer for pulverization to obtain phosphogypsum powder with a fineness of 200 mesh;

[0066] (2) Pretreatment of saline-alkali land: the planting site is the saline-alkali land of Haixing Bingjie Farm, and the total salt content of the topsoil at a depth of 0-20 cm is 0.61%. 15cm, 30cm wide ditch, the ditch distance is 40cm, phosphogypsum powder is evenly spread in the ditch and then covered with soil to fill it up. 20cm, 30 days after covering the film, take the film away and perform leaching treatment;

Abstract

The invention discloses a method for planting malus asiatica on saline-alkali soil. The method includes the steps that after preprocessing is conducted on the saline-alkali soil through ardealite, the saline-alkali soil is processed through oil cakes and compost, so that the soil structure of the saline-alkali soil is improved effectively, the soil pH value is lowered, the saline-alkali soil is made to be suitable for growth of the malus asiatica, the malus asiatica is planted on the saline-alkali soil, and in combination with control over all processes and technical parameters in the planting process, the stable and high yield of malus asiatica on the saline-alkali soil is achieved. By means of the method, the salt content and the pH value of the saline-alkali soil can be effectively lowered, the used main raw materials are wide in source, the price is low, the saline-alkali soil processing cost is greatly lowered, the compost and the oil cakes are utilized, and the problems of high cost and environmental pollution caused by stacking of the compost and the oil cakes can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of improvement of saline-alkali land, in particular to a method for planting bonuses on saline-alkali land. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkalized soil in my country is mostly...
