Embodiment 1

[0045] S1) preparation of straw cellulose, comprising the following steps:

[0046] S11) Weighing 100kg of wheat straw, cutting the straw into small sections of 5-10 cm; in specific implementation, one of straw, rice, corn, soybean or other crop straws, or a mixture of them can be used;

[0047] S12) adding water to the small section of wheat straw obtained in S11 until the wheat straw is completely submerged, and heating and boiling for 1 hour;

[0048] S13) filtering the wheat straw treated by S12 with a filter screen and drying it;

[0049] S14) Using a pulverizer to pulverize the straw obtained in S14 into 20-30 mesh straw powder;

[0050] S15) According to the dosage of 8L per kilogram, add NaOH solution with a mass concentration of 10% to the straw powder, and heat and boil for 45 minutes;

[0051] S16) filtering out the NaOH solution in the solid-liquid mixture of S15;

[0052] S17) Adding water to the solid obtained in S16 until the solid is completely submerged and...

Embodiment 2

[0058] The heating and boiling time in S12) is 1.5h;

[0059] S15) According to the dosage of 9L per kilogram, add a NaOH solution with a mass concentration of 13% to the straw powder, and heat and boil for 50 minutes;

[0060] S17) the pH value is adjusted to 7.2;

[0061] S21) Accurately weigh 13kg of straw cellulose prepared in S18, accurately weigh 13kg of glycerol, 13kg of methyl silicate, 0.3kg of brown nitrogen-fixing bacteria, 0.3kg of colloid bacillus, 0.3kg of jelly-like bacillus and 700kg water;

[0062] Except for the different conditions in the above-mentioned steps, the processes of other steps and the conditions of the steps are the same as those in Example 1, so as to obtain the degradable bio-mulch liquid in this example.

Embodiment 3

[0064] The heating and boiling time in S12) is 2h;

[0065] S15) According to the dosage of 10 L per kilogram, add NaOH solution with a mass concentration of 15% to the straw powder, and heat and boil for 60 minutes;

[0066] S17) the pH value is adjusted to 7.5;

[0067]S21) Accurately weigh 15kg of straw cellulose prepared in S18, accurately weigh 15kg of glycerol, 15kg of methyl silicate, 0.5kg of brown nitrogen-fixing bacteria, 0.5kg of colloid bacillus, 0.5kg of jelly-like bacillus and 800kg water;

[0068] Except for the different conditions in the above-mentioned steps, the processes of other steps and the conditions of the steps are the same as those in Example 1, so as to obtain the degradable bio-mulch liquid in this example.

Abstract

The invention discloses a degradable biological mulch film liquid and a preparation method thereof, and belongs to the field of technology related to agricultural planting. The degradable biological mulch film liquid is prepared from the following components in parts by weight: 10 to 15 parts of straw cellulose, 10 to 15 parts of glycerol, 10 to 15 parts of methyl silicate, 0.2 to 0.5 part of azotobacter vinelandii, 0.2 to 0.5 part of bacillus mucilaginosus, 0.2 to 0.5 part of tremelloid bacillus mucilaginosus and 500 to 800 parts of water; straw cellulose and the other components can form good mulch film, and plant photosynthesis is not hindered at the same time; glycerol and methyl silicate are used for water retention and water locking; the microorganisms can provide nutrient substancesrequired by plant growth; and comprehensive promotion effect is achieved on crop growth.

Description

technical field [0001] The invention relates to the technical field related to agricultural planting, in particular to a degradable bio-mulch liquid and a preparation method thereof. Background technique [0002] Because mulch film has the functions of water retention, fertilizer retention and moisturizing, and plays an important role in improving crop yield, mulch film is widely used in agricultural planting. [0003] The commonly used plastic mulch is extremely difficult to degrade due to its polymer structure, which can easily cause surface water to infiltrate into the ground. Long-term use will also cause soil salinization, which will eventually lead to a decline in soil quality and crop yield. [0004] Therefore, degradable bio-mulch has become the main direction of current research. There are also many related patent applications in China, but many of them are limited to easy degradation on the basis of water-proof and moisturizing functions, and their functions are re...
