Embodiment 1

[0028] In severe saline-alkali coastal beaches, the EC of the 0-20cm surface soil is 6.34ms / cm, and the soil pH is 8.28. Test location: Fanglingken District, Rudong City, Jiangsu Province; test time: October 2016-October 2017. The test plot was reclamated in 2000, and no artificial reclamation measures were carried out after the reclamation.

[0029] The field random block experiment was adopted, and the area of ​​each plot was 4.0m×4.0m. According to different soil amendment formulations, 6 treatments were set up in the experiment, namely CK, J1, J2, J3, J4, J5, and each treatment was repeated 3 times. In October 2016, the improvement agent was applied to each plot, and the sludge was mixed with the 0-20cm plow layer soil with a rotary tiller. In October 2017, soil samples were collected for measurement and analysis.

[0030] Among them, CK: blank, without any modifier, and other measures are exactly the same;

[0031] J1: 85 parts of domestic sludge; 5 parts of crop straw...

Embodiment 2

[0043] In light, medium and severe saline-alkali land along the coast, the salinity content of the 0-20cm surface soil is 2.77g / kg, 6.35g / kg, 22.19g / kg respectively, and the soil pH is 9.63, 9.02, 8.28 respectively. Test location: Fangling Reclamation District, Rudong City, Jiangsu Province, and Tiaozini Reclamation District, Dongtai, Jiangsu Province; test time: October 2016-October 2017. The test plot was reclamated in 2000, and no artificial reclamation measures were carried out after the reclamation.

[0044] The field random block experiment was adopted, and the area of ​​each plot was 4.0m×4.0m. In the test, 6 treatments were set up according to the formula of soil improver J4 with different dosages, 0, 1.5, 3, 4.5, 6, 9 tons / mu, and each treatment was repeated 3 times. In October 2016, the improvement agent was applied to each plot, and the sludge was mixed with the 0-20cm plow layer soil with a rotary tiller. From June 2017 to October 2017, corn crops were planted in ...

Embodiment 3

[0047] Embodiment 3 Soil part heavy metal activity change test

[0048] Soil sample: Pb 0.842 mg / kg; Cd 12.795 μg / kg; Cu 8.974 mg / kg; Zn 2.405 mg / kg.

[0049] Experimental method: get 6 parts of 20kg samples, add respectively the soil conditioner (each 2kg) of J1-J5 formula among the embodiment 1 in 5 parts of samples, mix evenly, guarantee that the quality moisture content is at 40%-60%, another 1 part As a blank control, after 1 month, the content of some effective heavy metals in the soil was detected, and the results are shown in the table below.

[0050]

[0051] The main reason why the content of available heavy metals in the soil of J1 and J5 groups increased instead of decreased was that domestic sludge and cow dung contained a certain amount of heavy metals in the formula.

Abstract

The invention relates to a mudflat saline-alkali land soil conditioner on the basis of using fermentation bed chicken farm wastes as raw materials and a preparation method thereof and application thereof. The mudflat saline-alkali land soil conditioner on the basis of using the fermentation bed chicken farm wastes as the raw materials comprises the following components of 75-85 parts of fermentation bed chicken farm wastes, 5-15 parts of crop straws, 2 parts of quick lime, 1 part of gypsum and 7 parts of wormcast in parts by weight. The mudflat saline-alkali land soil conditioner on the basisof using the fermentation bed chicken farm wastes as the raw materials, provided by the invention, has the advantages that technical bottlenecks of fermentation bed chicken farm waste resource utilization and mudflat saline-alkali land soil rapid conditioning are effectively solved; by combining the fermentation bed chicken farm wastes with the crop straws and the wormcast, the formation of mudflat soil aggregates can be effectively promoted, soil salinization can be inhibited, the pH value of the soil is reduced, organic matters and nutrients N and P in the soil are increased, soil structureconditioning and fertilization of the mudflat saline-alkali land are effectively promoted, and guarantee is provided for domestic agricultural land reserve resources.

Description

technical field [0001] The invention belongs to the field of resource utilization and soil improvement of waste from chicken farms in fermentation beds, and in particular relates to a tidal flat saline-alkali land soil improver based on waste from chicken farms in fermentation beds as a raw material, a preparation method and application thereof. Background technique [0002] The tidal flat land resources in the eastern part of my country are extensive and large, and can be used as important reserve cultivated land resources. They are mainly distributed in the coastal areas from Liaoning in the north to Guangdong, Guangxi and Hainan in the south, with a total area of ​​about 2.1704 million hm 2 . In the past 50 years, tidal flat reclamation has developed rapidly as an effective means to achieve "balance of cultivated land occupation and compensation". my country has added 1.1-1.2 million hm2 through tidal flat reclamation 2 land. According to the current sedimentation rate ...
