Abstract
Description
[0001] The invention relates to a saline soil water conservation and growth promotion ecological product based on resource utilization of invasive plants such as water hyacinth and a manufacturing method thereof, belonging to the field of biotechnology. Background Art
[0003] Microorganisms participate in the entire process of soil chemical cycle and can activate soil nutrients such as nitrogen, phosphorus and potassium for plant absorption. Some functional microorganisms can produce antagonistic substances to inhibit the growth of soil pathogens. By adding functional microorganisms to the soil, the absorption of nutrients by plants can be accelerated, effectively promoting plant growth and yield. However, the normal life activities of microorganisms require water to support them, and it is difficult for them to colonize in arid areas. Bentonite and polyacrylamide are good soil conditioners, which have good improvement effects on improving soil structure, increasing soil moisture and retaining fertilizer. Bentonite is a natural layered aluminosilicate mineral clay with the characteristics of high water absorption rate and high expansion multiple. The maximum water absorption capacity is 8 to 15 times its own volume. Polyacrylamide is a water-soluble linear high molecular polymer with a water absorption rate of 360 times. Polyacrylamide molecules ionize H when they come into contact with water. + , creating a concentration difference, so that water molecules move to the network structure in the polyacrylamide molecules under the action of osmotic pressure to form mesh water. Mesh water and free water can transform into each other under the action of osmotic pressure, slowly releasing water and continuously supplying water to plants. One disadvantage of polyacrylamide's soil water retention is that when the soil is saturated with water, its continuous absorption of water makes it difficult for plant roots to ventilate, which can easily cause plant damage. Summary of the invention
[0004] In order to overcome the shortcomings of the existing technology, the present invention discloses a saline soil water conservation and growth promotion ecological product based on the resource utilization of invasive plants such as water hyacinth and its manufacturing method, which belongs to the field of biotechnology. In addition to conventionally increasing the water retention capacity of the soil, this ecological product can also continuously supply moisture to functional microorganisms, maintain the number of functional microorganisms in the soil, and achieve the effect of promoting microbial growth.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: An ecological product for water conservation and growth promotion based on the resource utilization of invasive plants such as water hyacinth and its manufacturing method, characterized in that the ecological product is made from water hyacinth fermentation dehydrated residue, humic acid, bentonite, polyacrylamide, functional microorganisms and straw powder. The functional microorganism is Bacillus amyloliquefaciens Bacillus amyloliquefaciens IAE, the ecological product, has the function of retaining water and promoting growth.
[0006] Bacillus amyloliquefaciens Bacillus amyloliquefaciensThe strain deposit number of IAE is CCTCCNO.M2013086. It was deposited in the China Center for Type Culture Collection on March 15, 2013, and the deposit address is Luojia Mountain, Wuchang, Wuhan City.
[0007] The method for manufacturing a water-retaining and growth-promoting ecological product according to the present invention is characterized in that: a. 100 parts by weight of water hyacinth fermentation dehydrated residue, 0.3 to 0.6 parts by weight of Bacillus amyloliquefaciens Bacillus amyloliquefaciens IAE inoculum, mix thoroughly and ferment for 10-15 days; b. 2.5-3.5 parts by weight of humic acid, 1.2-2.0 parts by weight of bentonite, 3.5-5.5 parts by weight of polyacrylamide, 0.2-0.5 parts by weight of Bacillus amyloliquefaciens Bacillus amyloliquefaciens IAE inoculant and 1.5-3.5 parts by weight of straw powder were mixed thoroughly; c. The mixture in step b and the fermentation product in step a are thoroughly mixed; d. Disc granulation or bulk packaging, the resulting product is a saline soil water conservation and growth-promoting ecological product.
[0008] Furthermore, the density of the saline soil water conservation and growth promotion ecological product is 0.6-0.9 g·cm -3 , the moisture content is 18%~22%.
[0009] Beneficial effects: The water-retaining and growth-promoting ecological product provided by the present invention, which is manufactured by using water hyacinth fermentation dehydrated residue, humic acid, bentonite, polyacrylamide, straw powder and functional microorganisms, has the following advantages: Water retention in saline-alkali soil can reduce evaporation and avoid salt accumulation. Compared with pure polyacrylamide water retention products on the market, this product can supplement a large amount of low-salt organic matter. At the same time, under full irrigation and soil water saturation, it uses the gas production characteristics of straw powder carbon source decomposition by microorganisms to improve the ventilation capacity of the polyacrylamide environment and avoid soil compaction.
[0010] In arid areas, after the use of functional microorganisms in the soil, the number of microorganisms will drop sharply due to the weak water supply capacity of the soil, and the water supply capacity of conventional carriers such as organic fertilizers is weak. By replenishing water with polyacrylamide, microorganisms can be supplied with water for a longer period of time, which is conducive to the adaptation of microorganisms to the soil environment and ensures that the soil maintains a high number of functional microorganisms.
