Embodiment 1

[0048] A method for cultivating Platycodon grandiflorum in a greenhouse on saline-alkali land, comprising the following steps:

[0049] (1) Primary treatment of saline-alkali land: first crush phosphogypsum into 60-mesh fine powder, then adjust the water content in the saline-alkali land to 30%. The planting site is the saline-alkali land of Haixing Bingjie Farm. 0.14%, then evenly apply phosphogypsum powder on the surface of saline-alkali land, the application rate of phosphogypsum powder is 350kg / mu, then perform rotary tillage treatment, and after 14 days of film covering, remove the film and perform leaching treatment;

[0050] (2) Secondary treatment of saline-alkali land: adjust the moisture content of saline-alkali land to 40%, soak wild sweet melon seeds with warm water at 30°C for 10 hours, then spread them in saline-alkali land, and perform rotary tillage treatment. Within three months after sowing, watering and keeping The moisture content of the saline-alkali surfa...

Embodiment 2

[0057] A method for cultivating Platycodon grandiflorum in a greenhouse on saline-alkali land, comprising the following steps:

[0058] (1) Primary treatment of saline-alkali land: first crush phosphogypsum into 100-mesh fine powder, then adjust the water content in saline-alkali land to 40%. 0.56%, then evenly apply phosphogypsum powder on the surface of saline-alkali land, the application rate of phosphogypsum powder is 1000kg / mu, then perform rotary tillage treatment, and after 30 days of film covering, remove the film and perform leaching treatment;

Abstract

The invention discloses a method for cultivating platycodon grandiflorum in a saline-alkali land by means of a greenhouse. The method comprises the steps that ardealite is used for treating the saline-alkali land to remove most of salt in the saline-alkali land; ficus tikoua bur is planted to further remove the salt in the saline-alkali land; then wildland stems, mushroom bran and oil cakes are used for conducting further improvement on the saline-alkali land; after the improvement, the platycodon grandiflorum can be planted on the saline-alkali land, and high yield of the saline-alkali land can be achieved. According to the method for cultivating the platycodon grandiflorum in the saline-alkali land by means of the greenhouse, the main raw materials such as the ardealite, the oil cakes and the mushroom bran are low in price and wide in sources; particularly, the ardealite and the oil cakes are utilized, and the cost problem and the the environment pollution problem which are caused by heaping of the ardealite and the oil cakes can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for cultivating platycodon grandiflorum in a greenhouse 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 alkalize...
