Embodiment 1

[0058] A method for interplanting August melon and wild sweet potato on saline-alkali land, comprising the following steps:

[0059] (1) Pretreatment of saline-alkali land: the planting site is selected as coastal saline-alkali land, and its salt content is 0.2%. After drying the phosphogypsum to a moisture content of 5%, send it into a pulverizer and grind it into phosphogypsum with a fineness of 60 mesh. After crushing, it is beneficial to increase the contact area between phosphogypsum and the soil, and accelerate the reaction between phosphogypsum and the salt in the soil. Spread phosphogypsum powder and oily soil evenly on the saline-alkali soil. The application rate of phosphogypsum powder is 350kg / Mu, the application rate of oil dryness is 700kg / mu, followed by rotary tillage treatment, after 14 days of film covering, the film is removed and leaching treatment is carried out to remove the salt in the topsoil to the soil layer below;

[0060] (2) soil preparation: evenl...

Embodiment 2

[0067] A method for interplanting August melon and wild sweet potato on saline-alkali land, comprising the following steps:

[0068] (1) Pretreatment of saline-alkali land: the planting site is selected as coastal saline-alkali land, and its salt content is 0.3%. After drying the phosphogypsum to a moisture content of 7%, send it into a pulverizer and crush it into phosphogypsum with a fineness of 200 mesh. After crushing, it is beneficial to increase the contact area between phosphogypsum and the soil, and accelerate the reaction between phosphogypsum and the salt in the soil. Spread phosphogypsum powder and oily soil evenly on the saline-alkali soil. The application rate of phosphogypsum powder is 700kg / Mu, the application rate of oil dry is 1000kg / mu, followed by rotary tillage treatment, 16 days after the film is covered, the film is removed and leaching treatment is carried out to remove the salt in the topsoil to the soil layer below;

Embodiment 3

[0076] A method for interplanting August melon and wild sweet potato on saline-alkali land, comprising the following steps:

[0077] (1) Pretreatment of saline-alkali land: the planting site is selected as coastal saline-alkali land, and its salt content is 0.4%. After drying the phosphogypsum to a moisture content of 6%, send it into a pulverizer and grind it into phosphogypsum with a fineness of 80 mesh After crushing, it is beneficial to increase the contact area between phosphogypsum and the soil, and accelerate the reaction between phosphogypsum and the salt in the soil. Spread phosphogypsum powder and oily soil evenly on the saline-alkali soil. The application rate of phosphogypsum powder is 1200kg / Mu, the application rate of oil dryness is 1500kg / mu, followed by rotary tillage treatment, after 24 days of film covering, the film is removed and leaching treatment is carried out to remove the salt in the topsoil to the soil layer below;

Abstract

The invention discloses a method for interplanting holboellia latifolia and ficus tikoua bur in saline-alkali soil, and belongs to the technical field of saline-alkali soil improvement. The method includes the steps that the saline-alkali soil is pretreated through ardealite and oil cake; fertilization and furrow making treatment are carried out after most of salt in the saline-alkali soil is removed; afterwards, ficus tikoua bur seeds are sown on the furrow faces, then the holboellia latifolia is subjected to cuttage one year later, and final-period management is conducted on the holboellia latifolia. According to the method, the ficus tikoua bur and the holboellia latifolia are interplanted after the saline-alkali soil is improved, products such as holboellia latifolia fruits, ficus tikoua bur fruits and ficus tikoua bur rhizomes can be obtained, and obvious economic benefits are achieved; besides, due to the fact that the ficus tikoua bur grows lushly, a good moisturizing effect is achieved, the effect of preventing other weeds from growing and the effect of restraining salt return are further achieved, and therefore management cost is lowered.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a method for interplanting August melon and wild sweet 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 ...
