Problems solved by technology

Afforestation is an important method to improve coastal saline soil. However, due to poor site conditions, low soil organic matter content, and unsuitable afforestation technology, coastal saline soil afforestation technology still has disadvantages such as high cost, low sustainability, and low survival rate of seedlings.

Embodiment Construction

[0019] An embodiment is detailed below, but it is not limited to any one of these embodiments or similar examples.

[0020] 1. Overview of the implementation site

[0021] The south coast of Hangzhou Bay belongs to the north subtropical monsoon climate, and the characteristics of oceanic climate are relatively obvious. From July to August, due to less precipitation and strong evaporation, soluble salts continue to accumulate to the soil surface through capillary action, resulting in the occurrence of salinization; from August to September, tropical storms and typhoons and the impact of cold and warm air flow, Continuous rainy weather, high temperature, high humidity, and strong leaching effect make the soil produce seasonal desalination, and the alternating and repeated actions of desalination and resalination cause soil salinization.

[0022] The coastline on the south coast of Hangzhou Bay is 78.5 kilometers long, the altitude is only about 2.0-4.0m, the lowest point is onl...

Abstract

A method for increasing greening survival rate of seashore solonchak belongs to the technical field of seashore solonchak greening and is characterized by including steps of firstly, selecting tree seeds; secondly, planting trees; thirdly, improving soil; fourthly, reinforcing plants; fifthly, interplanting with manure; and sixthly, maintaining virescence. The method for increasing greening survival rate of seashore solonchak has the advantages that covering soil balls with rice chaff is low in cost, seedling roots are promoted to grow early, stress resistance is improved, and soil ventilation is enhanced; survival rate of seedlings is high and can reach more than 90%; both trees and shrubs can grow normally for a long period of time and never die of intolerance to salt and alkali two to three years after survival; and improvement is effective and salt content is lowered greatly.

Description

technical field [0001] The invention belongs to the technical field of coastal saline soil greening, and specifically relates to a method for improving the survival rate of coastal saline soil greening. Background technique [0002] Coastal saline soil mainly contains soluble salts mainly sodium chloride, and the serious salt accumulation leads to sparse vegetation, and crops cannot be cultivated without improvement. There are large areas of coastal saline soil in Liaodong Bay, Bohai Bay, Laizhou Bay, Hangzhou Bay and other areas in China, and there is a trend of continuous expansion, which hinders the development of local agriculture and forestry industries. In order to solve the technical problems of coastal saline soil greening and planting, for a long time, extensive research has been carried out on its improvement and utilization and greening and afforestation technology at home and abroad, and certain results have been achieved. Afforestation is an important method to...
