Problems solved by technology

On the one hand, the large-scale planting industry uses a large amount of chemical fertilizers and causes the loss of nitrogen and phosphorus to pollute the environment; on the other hand, the large-scale breeding industry also produces and discharges livestock manure and waste water to pollute the environment

Embodiment 1

[0082] 1. Experimental process

[0083] On the saline-alkali land, an ecological cycle planting greenhouse is set up. The greenhouse is a multi-span greenhouse with a steel structure frame, 40-45 meters wide from east to west, 4-5 meters high, and 10-15 meters long from north to south. The steel frame is used as the frame, and the top of the steel frame is provided with a semi-circular arc-shaped roof. The periphery of the steel frame is covered with a plastic film, and two layers of sunshade nets with a light transmittance of 30% are laid on the outside of the plastic film. An automatic opening and closing device is provided, and the part of the sunshade net with the automatic opening and closing device is located above the animal breeding area.

[0084] The greenhouse is divided into an animal breeding area and a plant planting area, the animal breeding area is located in the middle area of ​​the greenhouse, and the plant planting area is located on the east and west sides o...

Embodiment 2

[0103] In order to clarify the improvement effect of ecological cycle planting in greenhouses on saline-alkali land, the experiments were carried out in October 2012, April 2013, September 2013, June 2014, and October 2014. The S-type sampling method was used to collect 0 30 ~20cm soil samples were mixed, and 1kg soil samples were taken by quartering method and brought back to the laboratory for air-drying and grinding samples, and their basic physical and chemical properties such as total salt content, organic matter, alkaline nitrogen, available phosphorus, available potassium, and soil bulk density were measured. The specific test results are shown in Table 2. At the same time, soil microbial conditions in saline-alkali land were measured, and the specific test results are shown in Table 3.

[0104] It can be seen from Table 2 that the restoration effect of saline-alkali land is good by adopting the greenhouse ecological cycle planting method. After 2 years of ecological c...

Abstract

The invention belongs to the technical field of ecological and circulatory agriculture, and relates to a repairing method of a greenhouse ecological cycle planting and breeding saline and alkaline land. According to the greenhouse ecological cycle planting and breeding method, sheep are bred in a greenhouse, excreta of the sheep is fermented microbially and then used as feed for feeding earthworms, the excreta of the sheep and digestion decomposition substances are used as fertilizer to plant crops, and the grown crops are used as feed for feeding the sheep. The invention further provides application of the greenhouse ecological cycle planting and breeding method in saline and alkaline land repairing. The repairing method of the greenhouse ecological cycle planting and breeding saline and alkaline land is capable of effectively improving survival environment of animals and improving output quality of animal products and agricultural products like corn, produces true green agricultural products, effectively improves soil fertility of the saline and alkaline land, effectively inhibits soil-borne diseases of the facility greenhouse, and has remarkable economic and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of ecological cycle agriculture, and relates to a saline-alkali soil restoration method for ecological cycle planting in greenhouses, and in particular to a method for ecological cycle planting and cultivation in greenhouses and its application in saline-alkali land restoration. Background technique [0002] With the development of economy, the degree of agricultural intensification in our country is increasing day by day. The large-scale and intensive planting and breeding industry has gradually replaced the traditional rural economical planting and breeding methods. Along with the rapid economic and social development, there are serious environmental problems. According to the Bulletin of the First National Survey of Pollution Sources, agriculture has become the main source of pollution, and agricultural pollution sources are the largest contributor to chemical oxygen demand and the main source of total n...
