Description
Technical field
The present invention relates to soil improvement agent technical field, particularly, relate to the soil height carbon back additive that a kind of fermented maize stalk prepares.
Background technology
Along with the raising of China's farm output, the output of agricultural crop straw is also being multiplied.Made according to the relevent statistics, the output of the current all kinds of agricultural crop straw in the whole nation is reaching 7 ~ 1,000,000,000 tons every year, and its quantity is equivalent to 60 times of Northern grassland output.For a long time, the process problem of agricultural crop straw is the problem making vast farmers and governments at all levels feel more headache always, past is due to reasons such as the shortage of evaluation and exploration technology, market information are inaccessible and peasant's autumn ploughing sowing time is of short duration, most stalk goes out of use in river course, rot or directly destroyed by fire in field in roadside, not only block river course and road traffic, and severe contamination environment cause the huge waste of resource.
Due to stalk not easily decomposition in a short time, cause stalk resource reasonably not developed for a long time, except being on a small quantity used for heap making compost for packing ring, pasture, part, major part has all been burnt as life fuel, in the area that plant husbandry is main, crop material has become the obstacle in production.So crop straw burning, throughout vast rural area, causes the serious waste of environmental pollution and organic resource thus.According to statistics, the crop material that the whole nation is used as also field and organic fertilizer only accounts for about 20% of total amount, burns and accounts for 17%, after straw burning, primary product is carbonic acid gas, carbon monoxide, the obnoxious flavoures such as sulfurous gas, these gases cause serious environmental pollution after entering air.Crop straw burning do four large harms: one is waste resource, causes large amount of organic not go back to field; Two is serious environment pollutions; Three is frequent initiation fire and traffic accident; Four is destroy farmland ecosystem material cycle, causes soil fertility to decline.
Impact for the meticulousr crop of those nutritional requirements after soil and fertilizer declines is large especially, such as tobacco, tobacco is very strong to the adaptability of soil, from light sandy soil to heavy clay, from sour earth to alkaline soil, from light gray to the various soil such as yellow, red, black is native, the needs that tobacco growing is grown can be met.But the tobacco leaf local flavor that different soils is produced is different, the peppery people that chokes of some hardships, some aromatic alcohols and, what have is greyish white bright, the but grey black had stop working.So consider from the angle of quality of tobacco, the requirement of tobacco leaf production to edaphic condition is stricter.In order to improve the fertility of tobacco planting soil, tobacco grower tries to add in soil by after the crushed stalk such as paddy rice, corn, but, because stalk needs long time just can be completely broken down in soil, so stalk add the fertility that not only can not increase soil in time, what can affect tobacco on the contrary cultivates management.
At present, the multiple-microorganism Treating straw that is mixed is utilized to be popular solution.But the vigor of current published straw degradative bacterium is not very high, and is combined by multiple-microorganism, and the effect between microorganism is not simple additive effect, can produce antagonistic action time some bacterium mixes on the contrary.
Goal of the invention
The present invention, in order to overcome above-mentioned deficiency of the prior art, provides a kind of soil height carbon back additive; This additive is added in plant soil, especially in Tobacco, effectively can improve the fertility of soil, promote the growth of plant, and high carbon back additive of the present invention can also reduce the use of mineral manure.
