Embodiment 1

[0026] A planting method suitable for saline-alkali land trees and shrubs, the method is to lay a mixture M comprising greening plant waste, biochar, talcum powder, and montmorillonite minerals at the bottom of the tree hole for planting large trees, the greening plant waste, The volume ratio of biochar is 6:4, and 1000g of montmorillonite mineral is added to the mixture of greening plant waste and biochar per cubic meter.

[0027] Preferably, 80% of the particle size of greening plant waste in the mixture M should be 8-15mm, pH350g / kg. Enhance the adsorption capacity of salt ions.

[0028] The green plant waste refers to the tree and shrub trimmings (thinning), lawn trimmings, fallen leaves, branches, discarded grass flowers and weeds in gardens and flower beds produced in the natural or maintenance process of greening plants in urban green spaces or suburban woodlands. It is a green plant waste decomposed product obtained by composting and decomposing plant materials accord...

Abstract

The invention discloses a planting method suitable for trees and shrubs in saline-alkali land. According to the method, a mixture M including green plant waste, biochar, talcum powder and montmorillonite mineral is laid at the bottoms of tree holes for planting the large trees, the volume ratio of the green plant waste to the biochar is (6:4)-(7:3), and the adding amount of the montmorillonite mineral to the mixture of the green plant waste and the biochar is 1000-1500 g. The barrier adsorption performance of the green plant waste, biochar, calcium montmorillonite and the like is utilized, andnot only is a barrier effect on groundwater harming plants of the saline-alkali land achieved, but also the biochar, the calcium montmorillonite and the like have high adsorption to salt ions even ifgroundwater containing the salt ions enters the tree holes. At the same time, naphthalene acetic acid and other cell division promoting agents are added into the talcum powder, salt returning of thegroundwater of the saline-alkali land is effectively prevented, the soil in the planting holes can be prevented from saline-alkali damage in all directions at the same time, growth of plant roots canalso be promoted, and the planting method suitable for the large trees in the saline-alkali land is ecologically and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil planting, and in particular relates to a method for planting trees and shrubs suitable for saline-alkali soil. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil and various salinized and alkaline soils. Saline soil refers to the soil that contains a large amount of soluble salts so that most plants cannot grow. Its salt content is generally 0.6% to 1.0% or higher; Soil with a pH above 8. In fact, saline soil and alkaline soil are often mixed, so it is customarily called saline-alkali soil. [0003] At present, the global saline-alkali land area has reached 9.5 billion hm 2 , the distribution of saline-alkali soil is almost all over the country, such as the inland saline-alkali area in the northwest, the semi-arid saline-alkali area in the middle reaches of the Yellow River, the arid and semi-arid saline-alkali area in the Huanghuai-H...
