Embodiment 1

[0058] A method for planting August melon on saline-alkali land, comprising the following steps:

[0059] (1) Phosphogypsum pretreatment: After the phosphogypsum is dried to a moisture content of 5%, it is sent into a pulverizer to be pulverized into phosphogypsum powder with a fineness of 100 mesh. The contact area accelerates the reaction between phosphogypsum and the salt in the soil;

[0060] (2) Composting: Mix phosphogypsum powder, chicken manure, pig manure and cow manure evenly, and stack them for 100 days. Phosphogypsum reduces CO in the composting process. 2 、CH 4 and N 2 The emission of O can effectively improve the fertilizer efficiency of compost, and stacking chicken manure, pig manure and cow manure can promote the proliferation of microorganisms and provide a large number of microbial cells to saline-alkali land. During the stacking process, every 3 to 5 Turn it over once a day to reduce the compost temperature. If the temperature is too high, some nutrients...

Embodiment 2

[0067] A method for planting August melon on saline-alkali land, comprising the following steps:

[0068] (1) Phosphogypsum pretreatment: After the phosphogypsum is dried to a moisture content of 7%, it is sent to a pulverizer to be pulverized into phosphogypsum powder with a fineness of 200 meshes. After crushing, it is beneficial to increase the phosphogypsum and soil The contact area accelerates the reaction between phosphogypsum and the salt in the soil;

[0069] (2) Composting: Mix phosphogypsum powder, chicken manure, pig manure, and cow manure evenly, and stack them for 120 days. Phosphogypsum reduces CO in the composting process. 2 、CH 4 and N 2 The emission of O can effectively improve the fertilizer efficiency of compost, and stacking chicken manure, pig manure and cow manure can promote the proliferation of microorganisms and provide a large number of microbial cells to saline-alkali land. During the stacking process, every 3 to 5 Turn it over once a day to reduc...

Abstract

The invention discloses a method of planting Holboellia latifolia on saline-alkali soil. The method comprises steps of drying and smashing phosphogypsum to form phosphogypsum powder, mixing the phosphogypsum powder, chicken manure, pig manure and cow manure and piling up together to acquire compost, adjusting moisture content of the saline-alkali soil, evenly scattering the phosphogypsum powder on the saline-alkali and conducting rotary tillage, laying a thin film for a period of time, then taking the thin film away and conducting leaching, evenly applying the compost and oil cake to the processed saline-alkali, a period time of compartment formation, cutting Holboellia latifolia cuttage branches on the compartment surfaces, and managing the Holboellia latifolia seedlings. PH value and saline-alkali degree of the saline-alkali soil can be obviously reduced, so the saline-alkali soil is suitable for growth of the Holboellia latifolia and obvious economic benefits can be achieved.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for planting August melon 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...
