Embodiment 1

[0049] In step a, after the solar greenhouse facilities are built, a high ridge of 30 cm is built around it, flooded with flood water, and the water depth is maintained above 10 cm for 2-3 days, and the salt is washed with large water. Flood irrigation can avoid the problem of serious soil compaction caused by mechanical operation and the inability to directly plow the ground during the construction of the shed. While flooding the salt, it can properly improve the arableness of the soil through irrigation.

[0050]In step b, wait for about 10 days for the water to seep into the ground, level the land, evenly spread the crushed straw, crush the straw to about 3cm, plow 30cm-50cm deep, and expose to the sun for 15-30 days. In the embodiment of sprinkling, the crushed straw is applied, and the soil plowing layer can be increased by deep plowing of 30 cm. The turned down straw can form the straw salt barrier layer 4 between the root system of the crop and the lower layer of soil, s...

Embodiment 2

[0068] In step b, wait for the water to seep down to the ground, level the land, spread the crushed straw evenly, plow 50cm deep, and expose to the sun for 30 days.

[0069] In step c, spread decomposed organic fertilizer, base phosphate fertilizer, physiological acid fertilizer, trace element fertilizer and soil conditioner, plow 15cm; the consumption of superphosphate used is 60kg / mu, and the consumption of slow-release sulfur fertilizer is 10kg / mu. Mu, the dosage of granular magnesium sulfate is 10kg / mu, the dosage of biological humic acid fertilizer is 3kg / mu, and the soil conditioner is desulfurized gypsum powder, and the dosage is 45kg / mu; purpose sand.

[0070] In step d, pour flood water, put the film in a high temperature and stuffy shed for 15 days.

[0071] In step h, drip irrigation and topdressing during the crop growth period, the drip irrigation topdressing adopts the method of interval fertilization between biological bacterial fertilizer and water-soluble fer...

Abstract

The invention relates to a rapid soil improvement method suitable for a Xinjiang sunlight greenhouse. The method comprises the following steps: building a high ridge after the sunlight greenhouse is built, carrying out flood irrigation in broad water to leach salt, leveling land, uniformly spreading crushed straw, deeply plowing for 30-50cm, exposing for 15-30 days, then spreading a decomposed organic fertilizer, part of chemical fertilizer and a soil conditioner, plowing for 15-20cm, closing the greenhouse at high temperature for 15-30 days after flood irrigation, carrying out ditching and ridging, carrying out irrigation with field planting water, selecting a saline-alkaline tolerant variety, conducting short-stubble planting, carrying out mulching film covering after planting, spraying plant immune protein three times in the early stage of crop growth, and adopting an interval fertilization mode of a biological bacterial fertilizer and a water-soluble fertilizer for water dripping topdressing in the crop growth period; after crops are harvested, sowing annual salt-tolerant forage grass before next-stubble crops are planted. By means of the method, the soil of the newly-built Xinjiang sunlight greenhouse can be fully improved, the problems of soil salinization and hardening can be rapidly solved, and a good growth environment can be provided for crops during planting in the next year.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a rapid soil improvement method suitable for solar greenhouses in Xinjiang. Background technique [0002] Solar greenhouse vegetable cultivation is an important part of my country's agricultural production and the key to ensuring the safety of the people's "vegetable baskets". In recent years, relying on the unique climate environment in Xinjiang, solar greenhouses have developed rapidly, which has solved the problem of local vegetable supply to a certain extent. Vegetable cultivation in solar greenhouses has become an important way for local people to increase their income and become rich. [0003] In the prior art, the newly-built solar greenhouses in Xinjiang mainly have the following problems: Affected by soil-forming factors, the soil salt content of newly-built solar greenhouses in Xinjiang is relatively high, and under the influence of the continental arid desert ...
