Description
Technical field
The present invention relates to a kind of carbon back composite fertilizer, specifically, relate to a kind of carbon back composite fertilizer and preparation method thereof, belong to agricultural technology field.
Background technology
Some farm crop; as leguminous plants, melon, vegetables, the cash crop such as strawberry and some herbal medicine are planted in same field for years; often there will be blight; leaf blight; virus disease; cause crop yellow, even seedling, the death of even large stretch of plant, seriously affect the raising of yield and quality, this phenomenon is called as continuous cropping obstacle on cultivation.
The major cause of continuous cropping obstacle is caused to have the following aspects:
1. the pathogenic micro-organism increasing the weight of to have specificity to endanger to crop, insect and parasitics, association grow breeding.
2. affect the reason of soil, voltinism shape, fertilizer efficiency is reduced;
3. accelerate to consume some nutritive element, form nutrient and partially lose;
4. constantly accumulate some poisonous root exudates in soil, cause self " poisoning " of succession crop etc.
Reaction after Different Crop continuous cropping is different.Generally Gramineae, Cruciferae, the more resistance to continuous cropping of liliaceous crop; The not resistance to continuous cropping of pulse family, composite family, ground family crop.The harm of continuous cropping to deep rooted plant is greater than shallow root crop; Be greater than winter crops to the harm of summer crop, when same field is repeated plantation same crop, the time limit length at interval can be divided into 3 classes 1. to avoid the crop of continuous cropping as required.Same field being planted after 1 year needs interval just can plant for more than 2 years again.As green pepper etc. need every more than 3 years, watermelon, etc. every 5 years, then need need plant again after 10 years.2. the crop of resistance to short-term continuous cropping.Continuous cropping need be planted every 1 ~ 2 year after 1 ~ 2 year again, as beans, tuber crops etc.3. the crop of more resistance to continuous cropping, can continuous cropping 3 ~ 4 years even longer time.As paddy rice, cotton, Cauliflower etc.In cultivated land district more than a year, when same field adopting year after year the multiple cropping continuous cropping of same mode, though there is dissimilar crop to substitute plantation in 1 year, but still all harms of continuous cropping can be produced, as impeded drainage, soil physical and chemical property deterioration, disease and pest are on the rise, output is caused to reduce.
At present, for overcoming the evils that continuous cropping causes, the crop of usual implementation (rice field-upland field rotation) or the not resistance to continuous cropping of rotation in Multiple Cropping Rotation, its continuous cropping year number in the period of crop-rotation of the proportion of the crop expanding resistance to continuous cropping in crop rotation or proper extension, also have and adopt the multiple beneficial microorganism in probiotic bacterium stoste to eliminate these germs, and supplement the trace element taken away by crop because of continuous cropping.On the one hand, beneficial microorganism is got rid of harmful levels of pathogens and is contacted with crop, and kills part pathogenic bacterium, secretes some chemical substances being of value to plant simultaneously and promotes plant health growth; On the other hand, the chemical substance of crop root secretion and the cell of partial exfoliation death grow beneficial microorganism and surely grow and have importantly promoter action, and this reciprocal symbiosis relation between beneficial microorganism and crop is the power place overcoming continuous cropping continuous cropping.
Realizing in process of the present invention, contriver finds that prior art at least has the following disadvantages: although carry out crop rotation overcome in the evils that continuous cropping causes respond well, but by the restriction of the factors such as land area, this mode of continuous cropping is difficult to realize, especially, in northern planting vegetable in greenhouse, be difficult to especially realize crop rotation.
In addition, in soil, germ is of a great variety, and under different edaphic condition, microbial growth is subject to the impact of edaphic condition clearly, causes it to suppress the effect of germ unstable, undesirable.
Summary of the invention
The problem to be solved in the present invention is for above problem, provides a kind of carbon back composite fertilizer, overcomes the deficiencies in the prior art, the present invention seeks to the procreation effectively suppressing harmful levels of pathogens in soil, the generation of prevention soil-borne disease of crop.
Two of object improves crop yield, not by the impact of continuous cropping plantation.
