Nutrient solution for increasing survival rate of haloxylon ammodendron in arid regions and preparation method

Abstract

The invention provides a nutrient solution for improving the survival rate of haloxylon ammodendron in arid regions and a preparation method, the nutrient solution is prepared by the following steps:(1) preparing a culture medium: mixing brown sugar and well water according to a ratio of 1:3, heating the mixture to 100 DEG C, filtering out impurities after the brown sugar is completely dissolved,and cooling the solution to 30 DEG C; (2) strain fermentation: adding an EM strain, actinomycetes, bacillus subtilis and trichoderma harzianum, fully and uniformly stirring all the bacteria with polyglutamic acid and urea, putting the mixture into a fermentation tank after no obvious particulate matters exist, sealing the fermentation tank, and keeping the environment temperature of the fermentation tank between 25 DEG C and 35 DEG C, wherein the fermentation period is 5-7 days, and culturing the mixture to obtain a nutrient base solution; and (3) finished product blending: diluting the fermented nutrient base solution with well water, and finally mixing the nutrient base solution with ferrous sulfate, agricultural trace element water-soluble fertilizer, fulvic acid A and a biological organic fertilizer to obtain the nutrient solution. The nutrient solution prepared by the method greatly reduces the cost and labor intensity, saves a large amount of water resources, and improves the survival rate of haloxylon ammodendron trees in northern arid regions.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a plant planting nutrient solution, in particular to a nutrient solution for improving the survival rate of Haloxylon tree in arid areas and a preparation method thereof. Background technique [0002] The area with an annual rainfall of less than 150 mm in my country is about 1 million square kilometers. This vast area not only has a fragile and harsh ecological environment, but also brings extreme climate and sandstorm environmental impacts to other areas. In order to improve the ecological environment in these desert areas, the government has also invested heavily in planting Haloxylon over the years, but because of the dry climate, barren and salinized land, the survival rate is extremely low (only about 20% under the condition of watering 6 times a year) , with little effect, resulting in the waste of huge national investment and the low enthusiasm of the people for afforest...

In order to improve the ecological environment in these desert areas, the government has also invested heavily in planting Haloxylon over the years, but because of the dry climate, barren and salinized land, the survival rate is extremely low (only about 20% under the condition of watering 6 times a year) , with little effect, resulting in the waste of huge national investment and the low enthusiasm of the people for afforestation. Afforestation is in a situation where half the effort is half the effort, and the ecological environment governance is very difficult.
