Abstract

The invention provides a method for carrying out original-soil cultivation on moderate saline-alkaline land by adopting coco coir powder containing nutritional soil. The method comprises a land preparation step, wherein the land preparation step comprises the step of applying the nutritional soil, and the nutritional soil contains the following ingredients: red soil, pine needle mulch, a nitrogen-potassium-phosphate compound fertilizer, coco coir powder, dioscin, acetic acid, calcium bentonite, walnut green peel powder, tomato seed meal, chopped chaenomeles lagenaria pulp, tan yang sheep meal, hedgehog skin powder, a water retention agent and micro-elements. The invention further provides a preparation method for the nutritional soil. According to the cultivation method provided by the invention, the expense for transporting imported soil is saved, the cost is reduced, and the labor cost is reduced by 52%; the method plays roles in lowering the ion-exchange capacity of soil and lowering the salt content of the soil; and the relative water content of leaves of planted white bark pines is increased by 5.6% to 10.1%.

Description

technical field [0001] The invention relates to a method of using nutrient soil to plant white bark pine to carry out original soil cultivation on moderate saline-alkali land, in particular to a method for using nutrient soil containing coconut bran powder to carry out original soil cultivation on moderate saline-alkali land, which belongs to the original soil cultivation technology of saline-alkali land field. Background technique [0002] The saline-alkali land area in the world exceeds 900 million hectares, and the saline-alkali land of various types in my country reaches 100 million hectares. 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 sedimenta...
