Embodiment Construction

[0009] A planting method for saline-alkali land greening, the method comprising: removing the surface soil of the saline-alkali land, laying peat soil on the removed top soil, and planting greening plants on the paved peat soil. Described: the depth of the removed saline-alkali topsoil is 50 cm; described: the peat soil is first crushed by straw, then implanted with fermenting bacteria for fermentation, until the straw is not completely rotted, leaving 30% of the debris, and then Mix a small amount of tungsten element, and finally mix it with black soil. After mixing, mix with 40% tungsten-containing water. Using spraying technology, it is divided into four sprays, each interval, and spray again when the previous one is dry to 50%. Said: fermenting bacteria are implanted for fermentation, the fermentation time is 48 hours, the tungsten element accounts for 45% of the total straw, and the black soil accounts for 10% of the total straw.

Abstract

The invention belongs to the field of an improvement of a saline-alkali land, in particular to a planting method of saline-alkali land greening. The invention aims at overcoming the defects of an existing saline-alkali land improvement method and a saline-alkali land greening planting method. In order to achieve the purpose, the planting method includes removing surface soil of the saline-alkali land, laying turfy soil on removed surface soil, and planting green plant on laid turfy soil. The turfy soil is fermented by implanting zymophyte after straw is smashed, fermentaiton time is 48 hours, after the straw does not rot completely, remains of 30% are reserved, then micro tungsten essence is mixed, finally block soil is mixed, water with tungsten essence of 40% is mixed, spray technology is utilized, four spray is divided, and the planted greening plant is Dallis grass. The planting method of the saline-alkali land greening has the advantages of being capable of comprehensively utilizing the saline-alkali land in large area, adjusting a structure of the green plant of the saline-alkali land, expanding a coverage area of the green plant of the saline-alkali land, and protecting and improving ecological environment.

Description

technical field [0001] The invention belongs to the field of saline-alkali land improvement, and in particular relates to a planting method for saline-alkali land greening. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. At present, domestic treatment methods for saline-alkali land generally include salt discharge method and salt pressure method, etc., but they all have shortcomings. The amount of salt is reduced. The salt press...
