Problems solved by technology

[0005] In short, the technologies and methods currently used for improvement of saline-alkali soil in coastal tidal flats are either high in cost or poor in effect, and cannot be used for large-scale planting of economic crops, so they cannot be widely used in production. important reason

Embodiment 1

[0031] The polymerization method of improving tidal flat saline-alkali land and planting economic crops of the present embodiment includes the following processing steps:

[0032] (1) Build dikes for flood control and prevention of seawater intrusion

[0033] Select the tidal flat that needs to be improved, and build a dike on the side near the sea. The dike is 80cm high and 90cm wide. The length of the dike depends on the length of the tidal flat near the sea.

[0034] According to observations, strong typhoons and rainstorms occur frequently in the east and southeast of my country, and seawater intrusion occurs every 3-5 years in coastal areas due to typhoons and rainstorms. Therefore, if dikes are not built to prevent flooding and seawater intrusion, the improved saline-alkali land will be salinized again due to seawater intrusion.

[0035] (2) Establishment of salt drainage canal network

[0036] Build the main salt drainage canal from the high terrain to the low terrain...

Embodiment 2

[0046] The processing steps of the polymerization method of improving tidal flat saline-alkali land and planting economic crops in this embodiment are the same as in embodiment 1, except that step (3) deeply plows the saline-alkali land twice with an interval of 15 days.

Embodiment 3

[0048] The processing steps of the polymerization method of improving tidal flat saline-alkali land and planting economic crops of the present embodiment are the same as that of embodiment 1, except that the coarse sand in the nutrient soil used in step (4) accounts for 25%, and the organic fertilizer accounts for 15%.

Abstract

The invention discloses a polymerization method for improving mudflat saline-alkali land and planting commercial crops. The method particularly comprises the following steps of 1 flood prevention and saltwater intrusion prevention causeway constructing, 2 salt-elimination water ditch network establishing, 3 saline-alkali land pretreating, 4 isolation planting, 5 maintaining after planting and the like. According to the polymerization method, by means of ditch network salt elimination, natural rainwater salt leaching, local control of planting space and isolation of a plant root planting area from saline-alkali soil and effective planting of the commercial crops, the advantages of being low in cost, easy and convenient to operate and suitable for large-area development and utilization of the saline-alkali land are achieved.

Description

technical field [0001] The invention belongs to the field of soil improvement and agricultural planting, in particular to a polymerization method for improving tidal flat saline-alkali land and planting economic crops. Background technique [0002] my country's coastal provinces such as Jiangsu, Zhejiang, Liaoning, Fujian, Shandong, Guangdong, Hainan and other provinces have vast areas of tidal flats. Affected by seawater tides and seawater backflow caused by typhoons, the soil salinization in this area is serious. Soil salinization in coastal tidal flat area reduces the utilization rate of land and restricts the development of agricultural economy. The tidal flat saline-alkali land area in my country is 2.1704 million hectares, and the area that has been developed and utilized accounts for about 15%. Moreover, the unused tidal flat salinized soil in our country continues to increase in a large area every year. [0003] At present, measures such as physical, chemical, and ...
