Description
Technical field
The invention belongs to the field of preventing and curing diseases of intensive agriculture production fertilizer practice, relate in particular to a kind of compsn and application thereof that suppresses bacterial wilt of tomato.
Background technology
The ground of China's protection at present growing vegetables area constantly enlarges, owing to protect the growth of the suitable Ralstonia solanacearum of temperature and humidity condition in the ground, adds the continuous cropping of same kind, causes bacterial wilt to increase the weight of year by year.Mainly also be to use chemical pesticide to prevent and treat to the vegetables bacterial wilt at present, as: agricultural streptomycin, new strysolin and " shuang xiao ling " etc.But, use chemical pesticide not only can produce pesticide residue, and pathogenic bacteria also can increase gradually to the resistance of medicine, the vegetable grower can only strengthen the usage quantity of agricultural chemicals, and thus, agricultural chemicals uses and degree of dependence demonstrates vicious cycle.Make also simultaneously in the vegetables that the pesticide residue problem that exceeds standard is outstanding.In May, 2000, The Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC organized the agriculture chemical examination institution of 5 provinces and cities such as Beijing, Shanghai, Chongqing, Shandong and Zhejiang; To 50 vegetable varieties; The pesticide residue of 1293 samples are carried out sampling Detection; The pesticide residue exceeding standard rate reaches 30%, and the high person of residual concentration is several times even tens times of the permission residual quantity.The severe overweight of pesticide residue in the vegetables causes intoxication accident to happen occasionally.
In addition, blindness is bigger because present peasant applies fertilizer, soil ubiquity " eutrophication " and nutrient imbalance and the problem of depositing: cause a large amount of accumulation of nitrogen, phosphorus on the one hand, become the serious environmental source of pollution; On the other hand soil nutrient, particularly nitrogen, the phosphorus nutrient element is of serious failure, the strange phenomenon that " fertilizer " more will apply fertilizer more occurs, the vicious cycle of the formation nutrient wasting of resources.Simultaneously, because of nitrogen, phosphorus amount of application too high, and continuous cropping problem, the crop disease-resistant ability weakens, disease and pest is serious, it is increasing to cause agricultural chemicals to drop into, the medication frequency also increases day by day, is absorbed in the vicious cycle of morbidity and medication.Under the influence of long-term HS like this and high investment (particularly chemical fertilizer, agricultural chemicals) agriculture prodn and management style, Soil degradation is serious day by day, and continuous cropping obstacle highlights day by day.
Therefore, revert to core with soil health, the technology of repairing the degenerated soil ecosystem under the HS utilization through " balance fertilizing " is a kind of practical approach that solves continuous cropping obstacle from the source.
Summary of the invention
The technical problem that solves: the present invention is directed to the problem of the difficult anti-refractory of bacterial wilt of tomato, a kind of compsn and application thereof that suppresses bacterial wilt of tomato is provided.
Technical scheme:Suppressing the compsn of bacterial wilt of tomato, is that 45-60%:40-55% forms by mineral powder and fertilizer according to mass ratio, the said mineral powder quartzy 5-15 mass parts of serving as reasons; Alkali feldspar 10-15 mass parts, phosphatic rock 10-20 mass parts, hydromica 5-10 mass parts; Vermiculite 3-5 mass parts; Chlorite 10-15 mass parts, smectite 12-15 mass parts, the mixture that attapulgite 5-10 mass parts and kaolinite 5-10 mass parts are formed.
Said compsn suppresses the application in the bacterial wilt of tomato product in preparation, and the mass content of compsn in soil that wherein suppresses bacterial wilt of tomato reaches 2-4%.
Beneficial effect:The used mineral powder of this fertilizing method is the natural powder powder material of nontoxic pollution-free environmental protection.Contain a large amount of and middle micronutrient element that satisfies tomato growth, a series of spinoffs that do not have chemical fertilizer and agricultural chemicals to bring fully.And various nutrient element ratios are suitable, and life-time service helps the balance of soil nutrient element.And present technique is from ecological angle, through regulating soil nutrient, and control of plant bacterial wilt from the morbidity source, protection effect has sustainability.
In greenhouse test, present technique can play the effect of improvement continuous cropping vegetable field soil, makes soil pH only become neutrality (from 5.13 to 6.7) from acidity; Can also increase the living weight of tomato, the chlorophyll content of blade and the photosynthetic rate that promotes plant; In addition, the present invention is the generation of control of plant bacterial wilt effectively, and control effect is up to 89.99%.
