The invention provides a method for improving urban green land soil with wood vinegar fertilizer. The method comprises the following steps of: 1, selecting an urban green land to be improved, and detecting the physical and chemical properties of the soil; 2, preparing the wood vinegar fertilizer; 3, applying the wood vinegar fertilizer to the urban green land soil to improve the soil. According to the method, the wood vinegar fertilizer is applied to the urban green land soil to improve the physical and chemical properties of the soil. With the adoption of the method, the EC value, pH value, and soil bulk density of the soil can be reduced; the content of organic substances in the soil, the content of available nutrient, the number of microorganism and the total porosity can be increased; the method is beneficial for the growth of landscape plant in the green land as well as the achievement of landscape effect of the green land, and has high practical and economic value.

The invention discloses a method used for improving soil with kitchen waste compost. The method comprises steps such as biochar absorption of hydrogen peroxide, kitchen waste solid-liquid separation,mixing of dipped biochar and kitchen waste residue, mixing of decomposed forestry and agricultural residues and a waste residue 2, secondary composting fermentation, forming of kitchen waste fertilizer, preparing of mixed soil, and preparing of back filling soil. According to the method, hydrogen peroxide is adopted in the composting process, desulfurized gypsum powder is added in the step of preparing of back filling soil. The using of hydrogen peroxide is capable of improving the oxygen supply conditions in aerobic composting process, improving the salt leaching effect of the desulfurized gypsum powder, increasing the germination index of improved soil in plant growth utilization, and improving the compost improved soil quality comprehensively.

The invention relates to a method for producing forage maize in an underground water overexploitation restraining two-cropping region, and belongs to the technical field of agriculture. The productionmethod includes adopts a one-year-one-season forage maize planting mode or a white wheat-forage maize two-cropping planting mode, can lower the underground water overexploitation demand of high waterconsumption of white wheat to the greatest extent, can lower the demand for maize seeds, can utilize the advantages of the forage maize as fodder to sow the maize seeds before a rainy season is coming, can preferably water the maize with desalted pool water in a drought season, can ensure the high rate of emergence, can fully allow the forage maize to grow up in heavy rainfall months, can use thedesalted pool water to water the forage maize in the drought season, can determine the harvesting period according to the factors such as illumination, the accumulated temperature, the milk-filling degree, and the ensiling condition, can ensure the maximum benefit of forage maize planting, and can achieve dual objectives of benefits of the forage maize and water conservation.

A soil conditioner for facility agriculture planting is made from the following ingredients by weight: 10-40% of humic acid salt, 20-40% of diatomite, 0-30% of vermiculite, 10-20% of ammonium phosphate, 5-10% of dicyandiamide, the humic acid salt is selected from one of potassium humate and humic acid ammonium. The diatomite, the vermiculite and the ammonium phosphate are sifted through a 40-mesh sieve respectively. The humic acid salt and the dicyandiamide are sifted through a 100-mesh sieve respectively. The raw materials are then mixed uniformly according to the proportion of ingredients. According to the invention, the soil planting environment is effectively improved, and the soil in the facility agriculture planting area is significantly improved, the ability of the soil to retain water and nutrient is enhanced, the soil EC value of the soluble salt in the soil is reduced effectively, and the resistance of crops is strengthened.

The invention discloses a method for regulating and controlling sunflower water-fertilizer salt in a slight alkaline land. The method comprises the following steps: (1) selecting the slight alkaline land, (2) carrying out leaching before sowing, (3) carrying out land consolidation, and (4) selecting varieties, selecting '3638' sunflowers, and carrying out film mulching plantation. At the squaring stage of the sunflowers, irrigation water is 52 m3 / mu, and at the full duration stage of sunflower growth, the application number of the fertilizers is that base fertilizer diamine is 25 kg / mu, and topdressing urea is 15 kg / mu. The salt accumulating degree of a sunflower land using the regulation and control technology is lower than the salt accumulating degree of a local level, and water is saved.
