Embodiment 1

[0051] A method for cultivating apples on saline-alkali soil, comprising the following steps:

[0052] (1) Pretreatment of saline-alkali land: first dry the phosphogypsum and then send it to a pulverizer for pulverization to obtain phosphogypsum powder with a fineness of 60 meshes. The content is 35%. In the saline-alkali land, a ditch with a depth of 12cm and a width of 25cm is dug, and the distance between the ditch is 30cm. The phosphogypsum powder and oil dregs are evenly spread in the ditch and then filled with soil. The application amount of phosphogypsum powder is 350kg. / mu, the application rate of oil dryness was 700kg / mu respectively, followed by rotary tillage treatment, after 14 days of film coating, the film was taken away and leaching treatment;

[0053] (2) Land preparation: evenly apply farmyard manure and potassium dihydrogen phosphate on the saline-alkali soil surface after leaching treatment, and the application rates of farmyard manure and potassium dihydro...

Abstract

The invention discloses a method for cultivating apples in a saline and alkali land, and belongs to the technical field of improvements of saline and alkali lands. The method includes the steps that the water content of the saline and alkali land is adjusted, ardealite and oil cakes are evenly applied on the surface of the saline and alkali land, after being evenly mixed through rotary tillage, the ardealite, the oil cakes and surface soil of the saline and alkali land are covered with mulching films to preserve moisture for a period of time, the ardealite and the oil cakes take wide synergistic effect to greatly reduce the salinization degree of the saline and alkali land, the soil structure of the saline and alkali land is effectively improved, and the soil pH value is reduced; malus asiatica seedlings are transplanted to the saline and alkali land, then the apples are grafted to the malus asiatica seedlings serving as stocks, and therefore the apples can be planted in the saline and alkali land.

Description

technical field [0001] The invention relates to the technical field of improvement of saline-alkali land, in particular to a method for cultivating apples on saline-alkali land. Background technique [0002] Saline-alkali land is a general term for salt land and alkali 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 land refers to soils that contain carbonates or heavy phosphates, have a higher pH and are alkaline. Saline-alkali land has low organic matter content, low soil fertility, poor physical and chemical properties, and many anions and cations that are harmful to crops, making it difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is 99.13 million hectares. Most of the formation of alkaline land and alkaline soil in my country is related to the accumulation of carbonate ...
