Description

A kind of watermelon successive planting resistant agent and preparation method thereof
(One)Technical field
The present invention relates to a kind of successive planting resistant agent, more particularly to a kind of watermelon successive planting resistant agent and preparation method thereof.
(Two)Background technology
Watermelon belongs to Curcurbitaceae Citrullus watermelon seed, is annual herb plant.Watermelon succulence taste is sweet, containing multiple nutritional components, Can quench one's thirst and relieve summer heat, be one of fruit that people like.Due to planting habit and Regional Distribution, growth of watermelon is often present The phenomenon of continuous cropping plantation.Continuous cropping is also named continuous cropping, refers to continuously to plant same crop on one piece of field.Continuous cropping crop it is universal into Motility rate is low, undergrowth, root activity are low, resistance is poor, fibrous root is few, disease is heavy, result is small, yield poorly, poor quality, breeding time It is short.Watermelon is the crop for relatively avoiding continuous cropping, and continuous cropping production underproduction amplitude is general all more than 20%, and person high reaches 50% or even total crop failure.
The main cause one of the continuous cropping watermelon underproduction is that disease is aggravated, and droop is the important disease of watermelon continuous cropping, is also west The main cause of the melon continuous cropping underproduction.Withered germ of water-melon is mainly invaded by root wound or root hair apical cell gap, is first existed Host's tube wall iuntercellular and Intracellular growth, subsequently into vascular bundle, develop in conduit, germ secretion pectase and cellulose Enzyme, decomposes destruction cell, accumulation pectic substance in conduit, obstruction conduit is influenceed Water Transportation, is caused plant to be wilted.
Reason two be watermelon in growth and development process, root system constantly secretes various phenol acid substances and causes autointoxication, phenol Acid influences the respiration of watermelon, weakens absorbability of the watermelon to oxygen, and influence watermelon photosynthesis, reduces leaf Chlorophyll contents and photosynthetic rate, so as to cause weak watermelon growing way, retarded growth, yield poorly, poor quality.
Reason three is that continuous cropping plantation will certainly cause the nutrients such as Nitrogen In Soils, phosphorus, potassium, calcium excessive or lack, soil Middle nutrients ratio imbalance, makes growing for watermelon be affected, and yield declines, quality variation.
Reason four is that, with the increase of continuous cropping Planting Years, the fungi substantial increase of soil and rhizosphere makes bacteria type Soil is converted to fungi type soil, soil productivity exhaustion, is caused using plant for the saprophytic bacteria and pathogen of nutrition increase, because This often makes the increase of watermelon disease.
Reason five is that continuous cropping reduces the various hydrolytic enzyme activities in soil, the decomposition of various nutrition and micro- in influence soil Biological activity, causes plant nutrition not enough, depauperation.
The current anti-continuous crop technology of watermelon mainly has grafting cultivation, soil treatment, medicament disinfecting and applies microbial bacteria The technologies such as agent, but these methods still suffer from some defects and deficiency at present.
Grafting cultivation technology is mainly and uses with pumpkin, cucurbit etc. for stock carries out grafting, can significantly be dropped by grafting The incidence of disease of low watermelon blight, mitigates the Auto toxicity of root exudates so that watermelon is big, yield is high, but lacking of existing Point is to produce certain influence after Grafting watermelon to quality, and such as outward appearance is unsmooth, flesh is hard, poor taste, pol are low, not only takes When take a lot of work, while the generation of watermelon root-knot disease can be brought, and if be also not fee from same stock grafting throughout the year The generation of Auto toxicity.
Soil treatment and medicament disinfecting mainly process the technologies such as soil, pouring root, seed disinfection by the vexed canopy of high temperature, bactericide Pathogen is killed in measure, has certain effect to preventing and treating droop and other soil-borne diseases, can reduce the hair of watermelon blight Sick rate, improves yield, but the method easily causes residues of pesticides, so as to pollute environment, edaphon environment is destroyed, to product Quality safety threaten.
Biological pesticide or bio-feritlizer are made using the big multiplex bacillus of microbial bacterial agent method, Trichoderma, using spraying, The technical measures such as seed dressing, pouring root, fertilising are processed soil, seed, plant, can effectively prevent and treat watermelon blight, are eliminated Itself secretion poison, promote plant root growth, improve yield, but microbial bacterial agent when field uses due to by soil The influence of the factors such as nutritional condition, temperature, humidity and edaphon and generally existing soil application antibiosis strain colonization ability is poor, raw Speed long is slow, can not quickly form dominant population, the problems such as prevention effect is unstable.
In sum, it is either grafting cultivation, or chemical control, micro- in the anti-continuous crop technology of existing watermelon Bacteria agent is administered and all there is certain shortcoming and defect, therefore a kind of easy to use, ecological, environmental protective of research, nontoxic secondary work With, watermelon nutrition can be effectively provided, improve watermelon physiological situation, watermelon damage of successive crop can be effectively prevented and treated again, yield is improved, change The successive planting resistant agent of kind quality is the New Measure of watermelon continuous crop.
(Three)The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of ecological, environmental protective, can effectively provide watermelon nutrition, improves Watermelon physiological situation, can effectively prevent and treat watermelon damage of successive crop again, improve watermelon successive planting resistant agent of yield and preparation method thereof.
The present invention is achieved through the following technical solutions:
A kind of watermelon successive planting resistant agent, it is characterised in that be prepared from by the raw material comprising following percentage by weight:Trichoderma viride Agent 8-12 wt%, bacillus subtilis microbial inoculum 8-12 wt %, soyabean oligosaccharides 2-3 wt %, fulvic acid chelated calcium iron zinc-copper are combined Agent 50-60 wt %, wheat bran 6-12 wt %, maize flour 10-15 wt %.
The fulvic acid chelated calcium iron zinc-copper complexing agent is by potassium fulvate, calcium chloride, ferrous sulfate, copper sulphate, zinc sulfate Chelating dewatered drying is formed.
The preparation method of the fulvic acid chelated calcium iron zinc-copper complexing agent is that 10-15 grams of calcium chloride is added into 200 grams of water In, 100-120 grams of potassium fulvate is added after dissolving, it is stirred continuously, the chelatropic reaction 4-6h under the conditions of 40-60 DEG C, then successively Addition 8-12 grams of ferrous sulfate, 4-6 grams of zinc sulfate, 0.2-0.4 grams of copper sulphate, the chelatropic reaction 4-6h under the conditions of 40-60 DEG C, most Concentration drying afterwards obtains finished product.
