Embodiment 1

[0007] Plant Jerusalem artichoke in the desert, select seed and sow two parts, select seed: select the tubers with skin weight of 15g. Sowing: Soak the selected tubers in the pesticide carbendazim for 10 minutes, make the plant and row spacing 30cm square, and the depth of the sand pit is 10-12cm. Stir with solid water and sand in the pit, and the solid water in each pit is about 150g, sow fill sand. It is best to water at the seedling stage, jointing stage, budding stage and tuber expansion stage. At the jointing stage, topdress with 10kg of urea per acre to make the seedlings strong and multiple new shoots. At the beginning of budding, topdress with 15kg of potassium sulfate per acre, topdress and water, and pick flowers and buds during the tuber expansion period to promote tuber expansion.

Embodiment 2

[0009] Plant Jerusalem artichoke in the desert, select seed and sow two parts, select seed: select the tubers with skin weight of 15g. Sowing: Soak the selected tubers in the pesticide carbendazim for 12 minutes, 2,000 plants per mu, 1 kg of dry water-retaining agent is needed per mu, the depth of the sand pit is 11-14cm, and solid water soaked with water-retaining agent is used in the pit Mix with the sand, divide the solid water in each pit equally, plant the seeds and fill the sand.

Embodiment 3

[0011] Plant Jerusalem artichoke in the desert, select seed and sow two parts, select seed: select the tubers with skin weight of 20g. Sowing: Soak the selected tubers in the pesticide carbendazim for 12 minutes, make the plant spacing 40cm, the row spacing 40cm, the depth of the sand pit is 15-20cm, stir with solid water and sand in the pit, and the solid water in each pit is 180-200g , sow and fill with sand.

Abstract

The present invention relates to a method for controlling desert and sand by planting jerusalem artichoke, and said method includes two portions of selecting seed and sowing, in which the tuber with peel can be selected, and its sowing, includes the following steps: soaking the selected tuber in pesticide solution, stirrinbg solid water and sand in pit, sowing and filtering sand. It can greatly increase humic matter in the desert, and can change the desert into fat soil.

Description

(1) Technical field: [0001] The invention relates to a method for controlling desert sandy land. (two) background technology: [0002] At present, more than 1 / 4 of the country's land is desertified, and the direct economic loss caused by desertification reaches 54 billion yuan every year. The scope of potential occurrence areas, that is, the total area of ​​arid, semi-arid and sub-humid dry areas is 3.317 million square kilometers, accounting for 34.6% of the country's land area. Among them, the area of ​​desertified land is 2.62 million square kilometers, accounting for 27.3% of the area, equivalent to the area of ​​14 Guangdong provinces, and more than twice the total area of ​​cultivated land in the country. And it is expanding at a rate of 2,460 square kilometers per year, which is equivalent to losing the land area of ​​a medium-sized county every year. A large amount of human, material and financial resources have been invested in sand control, and the method adopted...
