This invention discloses a production method for preparing artificial land using various types of stones, a complete technology for preparing artificial soil through on-site crushing and application to the comprehensive transformation of national land. This invention employs on-site mobile processing, avoiding transportation costs. A single unit can produce soil for 1500 mu (approximately 100 hectares) annually, with a standard farmland cost of only 2658 yuan per mu, and the cost of remediating polluted farmland not exceeding 10,000 yuan per mu. The produced soil has a thickness of 33.3 cm, does not compact, and has extremely high water retention; even after 10 days at high temperatures, the moisture content of the lower layer still reaches 70%. Heavy metal content in the soil and agricultural products is far below national standards, mercury was not detected, and it is safe to grow all grains and vegetables. This invention can be applied on a large scale to the remediation of polluted farmland and the enhancement of carbon sequestration in industrial areas. It can rapidly increase soil carbon sequestration, lower temperatures, and transform ineffective rocky land into high-yield farmland, completely solving global problems such as the extremely slow formation, rapid loss, non-renewability, arable land shortage, and global warming of natural soils. One-time transformation benefits millennia, possessing extremely high economic, ecological, and social value.

This invention belongs to the field of rice cultivation technology, specifically relating to a method for synergistic yield increase through high-density rice planting and the application of silicate mineral materials. The method includes the following steps: before transplanting rice seedlings, applying silicate mineral materials to the soil at a rate of 4.5 tons / hectare to 6.0 tons / hectare in a single application; transplanting and high-density planting of rice seedlings; wherein the high-density planting density after transplanting is 312,000 hills / hectare to 345,000 hills / hectare. The method provided by this invention achieves a synergistic effect on rice growth and yield through high-density rice planting combined with the application of silicate mineral powder, essentially "compensating for weaknesses and synergizing advantages." The synergy of these two methods can alleviate the risk of lodging and nutrient competition caused by high-density planting, achieving the comprehensive goals of "nitrogen reduction, high-density planting, quality improvement, and stress resistance."

The invention relates to the field of agriculture and can be used in peasant farms, on the territory of which small- and medium-contour saline mixed soda and soda-sulphate heavy loamy solonetzic soils have become widespread. The method includes an early spring soil salt survey of the area to determine the state of solonetzic and saline soils, the development of a land reclamation strategy, the introduction of a calculated dose of sulfuric acid in the form of a solution, their incorporation to the depth of the solonetzic horizon, and the cultivation of alfalfa. This method allows for the production of up to 200 centners of fresh alfalfa per hectare per year on barren (due to soda salinity and alkalinity, there is virtually no vegetation) saline mixed soda and soda-sulfate solonetzic soils after their reclamation with a 1% sulfuric acid solution. The method improves the socioeconomic and environmental conditions of farms and farms where these soils are widespread. Key words: soda and soda-sulphate saline soils, chemical melioration, sulfuric acid, alfalfa, productivity.

The utility model relates to the field of agriculture, in particular to plant growing, and can be used in the cultivation of a perennial grain crop - grain wheatgrass for the conditions of semi-provided and unprovided dryland in the southeast of Kazakhstan with an annual rainfall of 200-400 mm. The technical solution of the utility model is drought resistance and efficient use of moisture, improvement of soil condition, stable grain and feed harvest, as well as reduction of costs for annual seed purchase and implementation of agrotechnical measures during its cultivation. The said technical result is achieved by a method of cultivating grain wheatgrass, which includes, in the first year, primary autumn tillage, pre-sowing surface tillage, winter sowing with rolling, and post-emergence treatment with a herbicide in the spring. According to the invention, primary tillage is carried out in the fall after harvesting the preceding crop once by plowing to a depth of 22-25 cm. Pre-sowing surface tillage is carried out by loosening the surface soil layer to a depth of 10-12 cm, sowing of grain wheatgrass is carried out in the fall using precision seeders in a wide-row method with a row spacing of 50 cm to a depth of 1-2 cm with simultaneous rolling and application of phosphorus fertilizers ammophos at a rate of P60 per 1 hectare, in the spring during the tillering phase, post-emergence treatment is carried out with the herbicide Ballerina at a rate of 0.4 l / ha in a tank mixture with the growth stimulator Beres 8 at a rate of 0.2 l / ha, and in the tube emergence phase, inter-row soil cultivation is carried out at a depth of 8-10 cm with the simultaneous application of ammonium nitrate at a rate of N60; in the earing phase, as pests appear, grain wheatgrass crops are treated with a tank mixture consisting of the insecticide Karatoshans at a rate of 0.2 l / ha and the growth stimulator Beres 8 at a rate of 0.2 l / ha. An additional technical result is achieved by cultivating grain wheatgrass according to the invention. In subsequent years, ammonium nitrate is applied early in the spring at a rate of N60, followed by light harrowing to lock in moisture. As the grain wheatgrass plants grow and develop, protective measures are implemented.
