Embodiment 1

[0042] Embodiment 1 A kind of method that adopts composite nutrient soil to carry out original soil greening to coastal saline-alkali soil

[0043] Include the following steps:

[0044] (1) Select saline-alkali land: the coastal saline-alkali land with deep soil layer will be selected. The indicators of this coastal saline-alkali land are: the terrain is approximately closed, the terrain is flat, the soil moisture content is 9-10%, the soil electrical conductivity is 2.10-2.30, and the hydrogen ion concentration index is 8.1- 10.3, soil bulk density 1.5-1.7g / cm³, porosity 37.5-39.5%.

[0045] (2) Composting and fertilizing: Mix phosphogypsum powder, sheep manure, vermicompost and biogas residue evenly, and stack them for 80-120 days. During the stacking process, turn them every 3-5 days to obtain compost and fertilize. Rotary tillage.

[0046] (3) Pretreatment of saline-alkali land: first adjust the moisture content in the saline-alkali land to 40-50%, and then apply phospho...

[0068] Described nutrient soil, by weight, comprises the following components:

[0069] 41 parts of peat soil, 47 parts of brick kiln soil, 17 parts of nitrogen, phosphorus and potassium compound fertilizer, 28 parts of montmorillonite, 11 parts of acai berry extract, 4 parts of ginkgo biloba extract, 5 parts of citric acid, 26 parts of pine needle powder, 13 parts of Monascus slag, 14 parts of tomato seed meal, 9 parts of litchi meat paste, 7.5 parts of shrimp shell powder, 7 parts of shell powder, 5.5 parts of water retaining agent, and 1.7 parts of trace elements.

Embodiment 3

[0070] Embodiment 3 A kind of method that adopts composite nutrient soil to carry out original soil greening to coastal saline-alkali soil

[0071] Planting method is the same as embodiment 1, and difference is only to change the composition of nutrient soil:

[0072] Described nutrient soil, by weight, comprises following component:

[0073] 38 parts of peat soil, 42 parts of brick kiln soil, 15 parts of nitrogen, phosphorus and potassium compound fertilizer, 19 parts of montmorillonite, 9 parts of acai berry extract, 3.6 parts of ginkgo biloba extract, 3.4 parts of citric acid, 19 parts of pine needle powder, 11 parts of Monascus slag, 12 parts of tomato seed meal, 5.7 parts of litchi meat paste, 6.2 parts of shrimp shell powder, 4.8 parts of shell powder, 4.5 parts of water retaining agent, and 1.2 parts of trace elements.

Abstract

The invention provides a method using a compound nutrient soil to carry out raw soil greening of coast saline-alkali soil; the method comprises the step of applying the nutrient soil; the nutrient soil comprises the following ingredients: turfy soil, brick powder kiln soil, nitrogen phosphor potassium composite fertilizer, montmorillonite, acai berry extract product, ginkgo biloba extract product, citric acid, pine needle powder, monascus slag, tomato seed meal, lichee meat mud, shrimp shell powder, shell powder, water-retaining agent and trace elements; the invention also provides a nutrient soil preparation method; the raw soil greening method can omit alien earth carrying cost, can reduce cost, can save labor cost by 45%, and can reduce soil conductivity, soil hydrogen ion concentration index and soil unit weight; the cactus planted in the soil prepared by the method can reduce the root rot disease down to 10.0-13.2%, and the cactus triterpene saponins content can be 1.46-1.65%.

Description

technical field [0001] The invention relates to a method for greening original soil of coastal saline-alkali soil by using nutrient soil, in particular to a method for greening original soil of coastal saline-alkali soil by using compound nutrient soil, and belongs to the technical field of original soil greening of saline-alkali land. Background technique [0002] With the rapid increase of population and the deteriorating weather conditions, the degree of land salinization in my country shows an obvious upward trend, and soil salinization has become an important limiting factor for the sustainable development of agriculture. In order to ensure the safety of food production in our country, improve the ecological environment, and realize the sustainable utilization of resources, it is imminent to accelerate the development of saline-alkali land improvement technology. [0003] The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million he...
