Description
Technical Field
The invention relates to the field of saline-alkali soil improvement methods, in particular to a saline-alkali soil plant planting improvement method.
Background
In the process of improving the saline-alkali soil, the green manure is often used for improving, because the green manure can not only fertilize the soil, but also has large coverage on the ground in the growth period and high transpiration amount, thereby reducing the evaporation and salt accumulation of the ground surface, being beneficial to the fall of the underground water level, and preventing the salt return of the ground surface. When the green manure is used, the decomposition of the green manure is very important, the decomposition degree is high, the fertilizer effect provided by the green manure is large, the decomposition degree is low, and the fertilizer effect provided by the green manure is small even if the amount of the green manure is large.

The technical scheme of the invention is as follows:
a method for planting and improving plants in saline-alkali soil comprises the following steps: (1) deeply turning over the saline-alkali soil to be flat and irrigated at the bottom of 9 months in the year, and planting overwintering green manure plants; (2) harvesting and crushing overwintering green manure plants 2-3 months in the next year, averagely assisting the saline-alkali ground surface, and sowing a compound fertilizer consisting of decomposed chicken manure, calcium superphosphate, calcium peroxide, a microbial fertilizer and urea on the saline-alkali ground surface before harvesting; (3) shallow-turning 10cm of saline-alkali soil, leveling, irrigating and ridging, wherein the ridge width is 70-80 cm, the ridge height is 10cm, and mulching is carried out on the saline-alkali soil; (4) planting sunflower in the beginning of 5 months in the next year.
Further, the overwintering green manure plants comprise one or more of mouse couch grass, alfalfa, astragalus sinicus, vetch and vegetables.
Further, the microbial fertilizer comprises halotolerant bacillus, bacillus subtilis, saccharomycetes, lactic acid bacteria, white rot fungi and cellulase.
Further, the compound fertilizer comprises the following components in parts by weight: 50-60 parts of decomposed chicken manure, 3-6 parts of calcium superphosphate, 2-5 parts of calcium peroxide, 1-2 parts of microbial fertilizer and 5-10 parts of urea.

Further, the application amount of the compound fertilizer is 200-400 KG/mu.
The principle of the invention is as follows:
the invention uses overwintering green manure plants to plant in late autumn and early winter of the year, harvests in early spring of the next year, covers the land in the whole winter, reduces the evaporation and salt accumulation of the land surface, prevents the salt from returning to the land surface, directly turns into the ground together with microbial fertilizer, decomposed chicken manure, calcium peroxide and urea after harvesting and crushing, covers the land surface with a film and preserves the temperature after irrigation, because of the function of the microbial fertilizer, the green manure turned into the ground starts to decay and decompose under the humid environment provided by the irrigation water, in the process, the decomposed chicken manure takes part in the action of urea to increase the ground temperature, and simultaneously the calcium peroxide slowly releases hydrogen peroxide and oxygen, since staphylococcus and micrococcus in the microbial fertilizer grow and reproduce, catalase can be produced, can decompose most of hydrogen peroxide into oxygen, provide good environment for the growth of microorganisms, and accelerate the decomposition of green manure. Meanwhile, due to the action of white rot fungi and cellulase in the microbial fertilizer, cellulose which is difficult to decompose in the green manure is better degraded, and saccharomycetes, lactic acid bacteria, thermophilic actinomycetes and thermophilic fungi play a main role in the decomposition of the green manure.
The invention has the beneficial effects that:
the overwintering green manure is used for planting on the ground surface, so that evaporation and salt accumulation on the ground surface in winter are reduced, and salt return on the ground surface is prevented; meanwhile, microbial bacterial manure, decomposed chicken manure, calcium peroxide and urea are added in the next green manure decomposing process, and mulching is used, so that a good environment is provided for the decomposing of the green manure, the fertilizer efficiency of the green manure is improved, sufficient nutrients are provided for the planting of next-year normal crops such as sunflowers, and the yield of the normal crops is improved. The invention has potential market value.
