Embodiment 1

[0046] Embodiment 1 A kind of method that adopts the nutrient soil of high water storage capacity to carry out original soil greening method to coastal saline-alkali land

[0047] Include the following steps:

[0048] 1) Site selection

[0049] Select the coastal saline-alkali land with deep soil layer. The coastal saline-alkali land index is: 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, the hydrogen ion concentration index is 8.1-10.3, and the soil bulk density is 1.5-1.7 g / cm³, porosity 37.5-39.5%.

[0050] 2) Choose planting time

[0051] Plant in late March to mid-April in spring, that is, afforestation when the soil thaws to a depth of 20-25cm.

[0052] 3) Select the seedlings of Eleuthero jujube and cut them to dry

[0053] Select annual seedlings with a height of 30 cm or more without pests and mechanical damage, and require that the seedlings are straight and strong, hav...

Abstract

The invention provides a method for carrying out original-soil greening on a coastal saline-alkaline land by adopting high-water-storage nutritional soil. The method comprises an original-soil treatment step, wherein the original-soil treatment step comprises the step of applying the nutritional soil, and the nutritional soil contains the following ingredients: yellow mud, peat soil, a nitrogen-potassium-phosphate compound fertilizer, natural stellerite powder, a serenoa repens extract, instantly-dissolved sodium silicate, dry bamboo shoot peel powder, bagasse, oil meal, Chinese wax gourd peel pulp, hairtail powder, well-composted rabbit manure, a water retention agent and trace elements. The invention further provides a preparation method for the nutritional soil. According to the planting method provided by the invention, the expense for transporting imported soil is saved, the cost is reduced, and the expense is saved by 37%; the method plays roles in lowering the soil seepage coefficient and increasing the moisture content of the soil; and the content of niacin in fruits of planted narrow-leaved oleaster is 2.1mg/100g to 3.2mg/100g.

Description

technical field [0001] The invention relates to a method for greening coastal saline-alkali land with nutrient soil, in particular to a method for greening coastal saline-alkali land with nutrient soil with high water storage capacity, and belongs to the technical field of original soil greening for saline-alkali land. Background technique [0002] There are 100 million hectares of saline-alkali land in my country, and the improvement of saline-alkali land is a worldwide problem. Saline-alkali land is a part of my country's important land resources, and 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 Delta along the Laizhou Bay, the sedimentary plains along the Bohai Bay, and the alluvial plains in the lower reaches of the Liaohe River along the Liaodong Bay. [0003] These areas are affected by seawater, with high grou...
