Problems solved by technology

These improvement technologies and methods have obvious shortcomings, such as excessive resource consumption, and some chemical amendments themselves contain substances that are toxic to plants, causing potential harm to the surrounding environment, and at the same time, the improvement of the soil is in a short-term apparent effect, which cannot be achieved. to cure or long-term effect
[0004] The existing soil improvers still have the following defects when improving soil: (1) The content of trace elements is low, which cannot meet the growth needs of plants; (2) For saline-alkali soils of carbonates, the ability to reduce salt is insufficient; (3) The improved soil has a high soil bulk density and is unstable, and the number of microorganisms in the soil is small; (4) the improved soil, planted with plants, has a low survival rate and poor growth

Abstract

A molybdenum-rich microbial fertilizer for saline-alkali land is provided. The microbial fertilizer comprises following components by mass: 50-56 parts of an organic fertilizer, 28-30 parts of peat, 5-7 parts of vermiculite, 3-7 parts of fulvic acid, 3-6 parts of a composite fertilizer, 0.4-0.6 part of a water-retaining agent, 0.5-0.9 part of a soil thickening agent, 0.1-0.5 part of a trace element fertilizer and 50 g / t of strains. Applications of the microbial fertilizer in plantation of tamarix austromongolica are also provided. The beneficial effects of the microbial fertilizer and the applications are that the soil salt content is reduced to 0.3-0.5%, the soda content of soil is reduced to 0.15-0.23 mg / 100 g, pH of the soil is reduced to 7.6-7.8, the soil bulk density is reduced to 0.92-0.96 g / cm<3>, actinomycetes and funguses in soil are increased, the survival rate of transplanting of the tamarix austromongolica is 95.7-98.7% and the tamarix austromongolica is well developed in root.

Description

technical field [0001] The invention provides a fertilizer and its application in the planting of Tamarix ammonosa, in particular relates to a molybdenum-rich microbial bacterial fertilizer in saline-alkali land and its application in the planting of Tamarix ammango, belonging to the technical field of soil fertilizers. Background technique [0002] The area of ​​saline soil in my country is about 34.6 million hectares, 7.6 million hectares of cultivated land are salinized, and nearly 1 / 5 of the cultivated land is salinized. The development of saline-alkali land improvement and utilization technology has extremely important practical significance for the sustainable and healthy development of my country, especially inland arid agriculture and rural economy, land management, and ecological environment protection. [0003] Domestic saline-alkali soil improvement methods and technologies are summarized as follows: (1) Physical improvement: land leveling, deep plowing, loosening...
