Problems solved by technology

[0003]However, the implementation of plastic film mulching cultivation also brings some problems, such as premature aging of film-covered crops, poor precipitation and infiltration, residual film pollution, and decline of film-covered soil fertility. So far, the decline of soil fertility has not attracted people's attention

Embodiment 1

[0027] Embodiment 1 A method for preventing fertility decline of film-covered soil based on straw returning to the field, comprising:

[0028] 1. Active liquid preparation

[0029] Add 17.5% D-sorbitol, 1% glutamine, 1% arabinose and sodium succinate blend, 0.5% succinic acid, 0.1% pyruvic acid and 0.1% malic acid to deionized water, stir and mix under vacuum Seal the mixed solution and let it stand at room temperature for 24-34 hours at 20-30° C. to obtain an active solution. The added active solution can obviously promote the activity of rhizobia, and at the same time, the effect of nitrogen fixation is greatly improved.

[0030] Two, solid fertilizer steps

[0031] 1. Fertilize the soil in spring, plant crops with strong nitrogen-fixing ability, and carry out mulching cultivation;

[0032] 2. After the autumn harvest, the crop stalks are divided into sections, the roots of the stalks are separated from the body, and the body is divided into small sections with a length of...

Embodiment 2

[0035] Embodiment 2 A method for preventing fertility decline of film-covered soil based on straw returning to the field, comprising:

[0036] 1. Active liquid preparation

[0037] Add 20.5% D-sorbitol, 5% glutamine, 5% arabinose and sodium succinate blend, 1.8% succinic acid, 1% pyruvic acid and 1% malic acid to deionized water and mix under vacuum Seal the mixed solution and let it stand at room temperature for 24-34 hours at 20-30° C. to obtain an active solution. The added active solution can obviously promote the activity of rhizobia, and at the same time, the effect of nitrogen fixation is greatly improved.

[0038] Two, solid fertilizer steps

Embodiment 3

[0043] Embodiment 3 A method for preventing fertility decline of film-covered soil based on straw returning to the field, comprising:

[0044] 1. Active liquid preparation

[0045] Add 23.5% D-sorbitol, 10% glutamine, 10% arabinose and sodium succinate blend, 3% succinic acid, 2% pyruvic acid and 2% malic acid to deionized water, stir and mix under vacuum Seal the mixed solution and let it stand at room temperature for 24-34 hours at 20-30° C. to obtain an active solution.

Abstract

The invention relates to the technical field of agricultural planting, in particular to a method for preventing fertility decline of film mulching soil based on straw returning to field. The method comprises the following operation steps that soil preparation and fertilization are carried out in spring, crops with high nitrogen fixation capacity are planted, and plastic film mulching cultivation is carried out; after autumn harvesting, crop straw is segmented, the roots and the bodies of the straw are separated, the bodies are divided into small segments, and the roots are smashed for standby application; the crushed straw roots are added into an active liquid to be mixed and stirred, and standing and drying are carried out to obtain nitrogen fixation fertilizer; and the nitrogen fixation fertilizer, inorganic fertilizer and straw bodies are cooperatively applied into the film mulching soil, soil turning and leveling are carried out, and then the fertilizer fixation work of the soil can be completed. Through the step of returning the straw to the field, the loss of soil fertility can be reduced, the soil fertility is gradually increased after the straws are returned to the field for many times, the added active liquid can promote the rhizobium at the roots of the straws to have an obvious promoting effect on the activity of the rhizobium, and meanwhile, the nitrogen fixation and fertility increasing effects are greatly improved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for preventing fertility decline of film-covered soil based on straw returning to the field. Background technique [0002] The use of plastic film mulching cultivation can reduce the evaporation of soil water, increase the ground temperature, enhance the activity of soil microorganisms, accelerate the transformation of nutrient elements that can be absorbed by crops, improve the effective fertility of the soil, and promote the growth and development of crops. Therefore, the use of plastic film mulching cultivation Tower, for many crops have obvious effects of increasing production and income. [0003] However, the implementation of plastic film mulching cultivation also brings some problems, such as premature aging of film-covered crops, poor precipitation and infiltration, residual film pollution, and decline in soil fertility of film-covered soil.
