Embodiment 1

[0020] For the production of microbial fertilizer, weigh 0.3 kg of Bacillus licheniformis, 0.3 kg of Halomonas halophilus, 0.3 kg of Agrobacterium aeruginosa, 0.15 kg of brown nitrogen-fixing bacteria, and 0.15 kg of brown nitrogen-fixing bacteria; in mineral fertilizers, 28 kg of medical stone, 9.6 kg of golden stone, 9.6 kg of zeolite; 14 kg of leaf humus, 14 kg of sawdust, 14 kg of horse manure and 7 kg of peat in organic materials; put them into a mixer and mix well; add controlled-release fertilizer particles in proportion while stirring, Among them, 28 kilograms of zinc sulfate, 28 kilograms of magnesium sulfate and 28 kilograms of ammonium chloride are mixed with 28 kilograms of water; weighed, packaged and applied. The mixed compound fertilizer is weighed and packaged, and transported to the work site for fertilization.

[0021] Field planting, according to plant spacing 5 meters, row spacing 5 meters, diameter is 80 centimeters, and depth is 80 centimeters to dig a pi...

Embodiment 2

[0027] Adopt the method for embodiment 1, only change the formula of microbial fertilizer, formula is as follows:

[0028] 0.12 kg of Bacillus licheniformis, 0.12 kg of Halomonas halophilus, 0.12 kg of Bacillus soil, 0.06 kg of brown nitrogen-fixing bacteria, 0.06 kg of brown nitrogen-fixing bacteria; 21 kg of medical stone, 7.2 kg of gold stone, and 7.2 kg of zeolite in mineral fertilizers kg; 12 kg of leaf humus, 12 kg of sawdust, 12 kg of horse manure and 6 kg of peat in organic materials; put them into a mixer and mix them evenly; add controlled-release fertilizer granules in proportion while stirring, including 28 kg of zinc sulfate, Magnesium 28 kilograms and ammonium chloride 28 kilograms, add water 28 kilograms.

[0029] The invention effectively improves the saline-alkali soil. After one year of planting, the soil PH value is significantly reduced, the soil salt content is reduced, and the plant survival rate is higher.

Embodiment 3

[0031] Adopt the method of embodiment 1, only change the application rate of microbial fertilizer, the application rate of Populus euphratica plant is 40 kilograms per plant of Populus euphratica, 20 kilograms per plant of Nitraria euphratica.

[0032] The invention effectively improves the saline-alkali soil. After one year of planting, the soil PH value is significantly reduced, the soil salt content is reduced, and the plant survival rate is higher.

Abstract

The invention relates to a method for planting populus euphratica in saline and alkaline land. The method comprises the steps that pits are dug in the saline and alkaline land, wherein the pits are dug according to the requirements that the plant spacing is 5 m, the line spacing is 5 m, the diameter is 80 cm, and the depth is 80 cm; microbial fertilizer is applied at the bottoms of the pits, the microbial fertilizer and bottom soil are mixed to be uniform, and populus euphratica plants are put into the pits and covered with soil; a pit with the diameter of 30 cm and the depth of 40 cm is dug between every two adjacent populus euphratica plants and wetted with fresh water, microbial fertilizer is applied, and nitraria tangutorum plants are put into the pits according to the specification of about 200 plants per mu and covered with soil; planting soil is spread on the surface; after field planting is conducted, free flooding irrigation is conducted; daily management of the trees is conducted; pruning and weeding or pest control are conducted. According to the method, saline-alkaline land reclamation is conducted by taking the populus euphratica as a main means, cooperating with planting of the nitraria tangutorum plants and coordinating with the microbial fertilizer, soil of a planting area is effectively improved, the PH value of the soil is decreased to 7.1, the alkalization degree of the soil is decreased to 2.5%, the salt content is decreased to 0.15%, the survival rate of the plants is 95% or above, and economic benefits are significantly increased.

Description

technical field [0001] The invention relates to the field of soil improvement in saline-alkali land, in particular to a method for planting Populus euphratica in saline-alkali land. Background technique [0002] In recent years, with the interference of human economic and social activities and the intensification of natural disasters, my country's ecological environment has continued to deteriorate. The dry climate, barren soil and heavy salinity have greatly reduced the vegetation coverage. In order to further prevent the deterioration of the ecological environment, my country has carried out large-scale afforestation projects in saline-alkali land, and often chooses tree species suitable for planting in saline-alkali land. It is meaningless and causes a waste of human and material resources. And after becoming a forest, the economic added value brought is relatively small. In order to improve this situation, it is necessary to vigorously select excellent tree species that ...
