Embodiment 1

[0046] Put the seed liquids of Bacillus megaterium, Bacillus amyloliquefaciens, Bacillus thuringiensis, Bacillus colioids, and Azotobacter torus respectively into their respective fermentation medium, at 37°C, at a speed of 300rpm, with a ventilation ratio of 1:1, and ferment for 20 hours Collect the fermented liquid, add diatomaceous earth to fix it, and mix the five bacterial liquids in equal amounts;

[0047] The parts by weight of each component of the compound nutrient are: 8 parts of urea, 4 parts of monoammonium phosphate, 4 parts of potassium sulfate, 15 parts of chelated calcium, 7.5 parts of magnesium sulfate, 7.5 parts of chelated magnesium, 3 parts of sodium silicate, 4 parts of zinc, 4 parts of chelated zinc, 2 parts of manganese sulfate, 2 parts of chelated manganese, 8 parts of boric acid, 8 parts of chelated iron, 4 parts of chelated copper, 0.5 parts of humic acid, 5 parts of soybean peptone, compound amino acid 3 copies

[0048] The parts by weight of each c...

Embodiment 2

[0052] After mixing the bacterial liquid and compound nutrient described in Example 1, add polyglutamic acid in a mass ratio of 0.1:1:1 to polyglutamic acid, bacterial liquid, and compound nutrient, mix evenly, and fill to obtain product B. Take product B and dilute it by 200 times, and pour it on the soil surface of highland barley, and pour this product every 7 days, and regularly measure the germination rate, plant height, water content, temperature and pH.

Embodiment 3

[0054] After the bacterial liquid described in Example 1 is mixed with the compound nutrient, add the pullulan, polyglutamic acid successively with the mass ratio of pullulan, polyglutamic acid, bacterial liquid, and compound nutrient 0.1:0.1:1:1 , mixing, and filling to obtain product C. Take product C and dilute it by 200 times, and pour it on the soil surface of highland barley, and pour this product every 7 days, and regularly measure the germination rate, plant height, water content, temperature and pH.

Abstract

The invention provides a novel compound microbial fertilizer containing Pulullan and polyglutamic acid and a preparation method of the novel compound microbial fertilizer. The compound microbial fertilizer comprises a microbial fermentation inoculum, compound nutrients, Pulullan and polyglutamic acid, wherein the microbial fermentation inoculum is prepared by mixing fermentation liquors of bacillus megatherium, bacillus amyloliquefaciens, bacillus thuringiensis, bacillus mucilaginosus and azotobacter chroococcum according to the mass ratio of 1: 1: 1: 1: 1; the compound nutrients comprise nitrogen, phosphorus, potassium, trace elements, organic matters and compound amino acids. By applying the microbial fertilizer, the bud ratio, the plant height and the yield of highland barley can be obviously improved, and the highland barley is excellent in taste. Furthermore, the use level of irrigation water can be reduced by 10% due to the film-forming property of Pulullan and the water-retaining property of polyglutamic acid. In addition, Pulullan and polyglutamic acid are mixed to form a liquid mulch on the surface of soil, so that the use of a plastic thin film can be reduced, an environmental protective role can be played, the labor force is alleviated, and the cost is lowered by 10-20%.

Description

technical field [0001] The invention belongs to the field of compound microbial bacterial fertilizer, and in particular relates to a compound microbial fertilizer containing pullulan and polyglutamic acid and a preparation method thereof. Background technique [0002] Today is an era of ecological civilization, and the pursuit of harmonious development between man and nature is the main theme of today's social development. my country has a vast territory and a large population, and is facing the current situation that the per capita arable land area is relatively small, so it is necessary to increase production. The application of chemical fertilizers is a common way to increase production. However, the long-term application of chemical fertilizers leads to problems such as soil compaction, reduction of soil microbial species and numbers, damage to soil ecosystems, impact on the quality of agricultural products, and environmental pollution. The development and application ...
