Embodiment 1

[0046] Embodiment 1 A kind of method that adopts the nutrient soil that can improve soil permeability to carry out original soil cultivation method to severe saline-alkali land

[0047] Include the following steps:

[0048] A. Site selection

[0049] The base is located in the southwest of Binhai Development Zone, Weifang City, Shandong Province. It has a warm temperate marine monsoon climate, with an annual average temperature of 11.8°C, an average temperature of -4.6°C in January, an extreme minimum temperature of -20.3°C, and a frost-free period of 217 days. The annual sunshine hours are 2718.8 hours, and the average annual precipitation is 627.9mm, mainly concentrated in July-August, accounting for 74% of the annual precipitation. The soil of the base is saline soil with severe saline-alkali soil, the soil salt content is 8.4-9.5g / kg, the soil has strong viscosity, poor drainage and water permeability, the soil porosity is 30.5%, the groundwater table is shallow, with an ...

Abstract

The invention provides a method of performing natural soil cultivation on strongly saline-alkaline soil by using nutrient soil capable of improving soil permeability. The method comprises a step of applying nutrient soil. The nutrient soil contains the following ingredients: lotus pond sludge, garden soil, nitrogen-phosphorus-potassium compound fertilizer, medical stones, Euterpe oleracea extract, protocatechuic acid, peanut shells, glycyrrhiza residues, cottonseed meal, pineapple peel pulp, animal bone calcium powder and animal marrow powder, shell powder, a water-retaining agent and trace elements. The invention also provides a method for preparing the nutrient soil. The planting method saves the expense for carrying soil from other places, reduces the greening cost, and achieves the effects of reducing the soil ESP and increasing the available phosphorus content of soil; with the method, the survival rate of seedlings of tamarix chinensis reaches 92.5-95.2%.

Description

technical field [0001] The invention relates to a method for using nutrient soil to carry out original soil cultivation on severe saline-alkali land, in particular to a method for using nutrient soil which can improve soil permeability to carry out original soil cultivation on severe saline-alkali land, and belongs to the technical field of original soil cultivation on saline-alkali land. Background technique [0002] There are 100 million hectares of saline-alkali land in my country. Saline-alkali land is a part of my country's important land resources. Saline-alkali soil occupies a large proportion of wasteland resources. The saline-alkali land in the northern coastal areas of my country is mainly distributed in the Bohai Rim, including the Yellow River along the Laizhou Bay. The delta, the sedimentary plain along the coast of Bohai Bay, and the alluvial plain of the lower reaches of the Liaohe River along the coast of Liaodong Bay. [0003] These areas are affected by seaw...
