Abstract
The invention discloses a straw biological fertilizer as well as a preparation method and application thereof. The straw biological fertilizer is prepared from core materials including plant straws and bacillus subtilis and comprises the plant straws, bacillus subtilis and auxiliary materials; plant straws are fermented by bacillus subtilis in soil, and a large number of carbon nutrients in the plant straws are absorbed by roots and leaves of plants, so that the utilization rate of the nutrients of the plant straws is increased, meanwhile, the content of carbon dioxide exhausted into the atmosphere is reduced, and the ventilation and the water storage capacities of soil are effectively enhanced; the straw biological fertilizer is applied to a site 40cm deeper than a soil layer in an application process, so that poisoning of the roots of the plants caused by reductive toxicants is avoided, the penetration growth of the roots of the plants is promoted, the absorbency increasing of the nutritive area of the plants along the plant straws in deep soil is promoted, the effects of loosening deep soil and increasing the porosity of deep soil and the numbers of vent pores and capillary pores are achieved, and the purposes of enhancing the ventilation and the water storage capacities of deep soil are achieved.
Description
Technical field
The present invention relates to bio-fertilizer technical field, particularly a kind of straw biological fertilizer and preparation method thereof and application.
Background technology
Plant-growth needs the factor such as light, heat, gas, water, fertilizer to coordinate and the supply of abundance, nutrients resource mainly come from the last decomposition release of soil mineral mineral nutrient, the recycle of organic organic nutrient and the mankind be manured into soil in various fertilizer nutrient elements.Crop land soil nutrient mainly comes from the various chemical fertilizer and organic fertilizer that the mankind are manured into soil.Due to using in a large number of chemical fertilizer, the serious problems of soil pollution, water resource pollution, food heavy metal contamination are there are.
2015, National agricultural portion formulates " 1 control 2 subtracts 3 basic " Sustainable development route, particular content is: control agricultural irrigation water amount, minimizing chemical fertilizer, minimizing chemical pesticide consumption and straw animal manures application mulch film and substantially reclaim, the core of Sustainable development route reduces the consumption that heavy chemicals enters soil system, recycles agriculture organic materials energetically.The core of Term Fertilization reduces chemical fertilizer to use, and strengthens organic fertilizer and use.China's agricultural application fertilizer is with a long history, and the manure type used is various, and main Types has compost, barnyard manure, makes compost, straw-returning.
Still have problems, to produce and to use maximum compost in China's organic fertilizer production and use.In order to the macromolecule organics such as Mierocrystalline cellulose, protein, xylogen are decomposed into small organic molecule and mineral nutrient, be beneficial to plant absorbing nutrient, and avoid reducing substances such as the organic acid produced in decomposition course to produce murder by poisoning to root system of plant, compost needs the thermophilic fermentation carrying out at least 30 days in producing.But the carbon element decompose of nutrient of organic fermentation materials is carbonic acid gas by thermophilic fermentation, the volatilization loss of carbon element and nitrogen nutrient is caused to be broken down into Ammonia valatilization loss; The degraded of Mierocrystalline cellulose and xylogen, reduces the ability of organic fermentation materials chessom and improves the ability of soil aeration retaining; In compost application, impose in 25 centimetres of dark soil layers, the proterties of topsoil can only be improved, deep soil proterties is not improved.
