Problems solved by technology

Afforestation planting by aircraft sowing has the characteristics of less investment, fast speed, high benefit and wide application range. However, there are still many deficiencies in the pelletization of seeds that are critical to the survival rate of aerial sowing afforestation.
One is that the seeds sown by air are treated according to the method of agricultural coating, the seeds are lighter after treatment, and the problem of drifting with the wind still cannot be solved; the other is that the weight of the seeds is increased by the pelletization technology, but the contradiction between damage and germination is not solved , either the bonding strength is not enough, and the breakage rate of the pelleted seeds is high during transportation and aerial sowing, or the bonding strength is too high, and the seeds cannot germinate

Embodiment 1

[0012] Select Calligonum alaschanicum as pasture for planting, mix the matrix components, extrude through a granulation extruder to form a columnar granular matrix with a diameter less than 4mm and a length of 5-15mm, and the matrix consists of the following parts by weight: Composed of: straw powder or decomposed organic matter: 10-30 parts, plant growth regulator: 0.01-0.04 parts, water-absorbing resin: 1-15 parts, filler: 55-65 parts, adhesive: 1-5 parts; Insecticide: 1-6 parts; Fungicide: 0.5-1 part; Urea: 1-8 parts; Potassium dihydrogen phosphate: 1-8 parts; Ferrous sulfate: 1-1.2 parts; Magnesium sulfate: 1-1.2 parts; Zinc sulfate: 1-1.2 parts;

[0013] 2) Mixing the forage seeds with the columnar granular matrix, the mixing ratio is 1:150;

[0014] 3) Use a double-roll extrusion granulator to extrude the forage seeds and the columnar granular matrix for granulation, with an extrusion strength of 8 Pa, to form oblate spheroidal granules with a diameter of 4-10 mm.

Abstract

The invention discloses a method for transforming desert through seeding. The method is characterized by comprising the steps of (1) carrying out aerial seeding of grass seeds after granulating treatment, mixing matrix ingredients, and extruding through a granulating extruder to form a cylindrical granular matrix of which the diameter is smaller than 4mm and the length is 5-15mm; (2) mixing the grass seeds with the cylindrical granular matrix in the ratio of 1:150; and (3) extruding the grass seeds by adopting a roll extrusion granulator, and granulating the cylindrical granular matrix to form vegetative granules of which the diameters are 4-10mm, wherein the extrusion strength is 8pa.

Description

technical field [0001] The invention relates to a method for controlling deserts, in particular to a method for transforming deserts by planting grass. Background technique [0002] my country is one of the countries with serious sandy desertification hazards in the world. The national desert and desertified land area is about 153.13 million km2, accounting for 16% of the national land area, exceeding the sum of the national cultivated land area. Desertification has brought great harm to the ecological environment and society, and seriously restricted the sustainable development of my country's social economy. Desert areas are sparsely populated, labor shortage, inconvenient transportation, coupled with the constraints of water conditions, artificial forestation is difficult and costly. In order to speed up the pace of governance and change the vicious circle of the fragile ecological environment, aerial seeding afforestation has been carried out in China. Afforestation pl...
