Description

A kind of production method of preventing and treating soil root knot nematode organic fertilizer
(1) technical field
The present invention relates to agrochemical field, particularly a kind of production method of preventing and treating soil root knot nematode organic fertilizer.
(2) background technology
Over past ten years, protection ground vegetable growing is rapid in China's development, and protection ground, whole nation area has reached 2,000,000 hm 2Along with the adjustment of agricultural planting structure, protection ground will continue development in future.The crop of cultivation also will be developed to directions such as flowers, fruit tree, nursery, herbal medicine by current vegetables.The development on protection ground, also generation, the development for root knot nematode provides adapt circumstance.According to investigations, root knot nematode is the plant nematode the widest and that harm is the most serious that distributes in the world, the plant more than 2000 kinds that almost comprises all raise crops is in the world infected all very responsive to root knot nematode, 30 various vegetables such as the normal harm of soil root knot nematode is melon, solanberry class, beans and radish, calabash radish, lettuce, Chinese cabbage, the root of the various vegetables of main harm, infect the back and form tumour, influence plant to moisture and nutrient absorbing.Short and small, slow, the leaf color anomaly of killed strain aerial growth, the result is few, and the fruit deformity yields poorly, and plant is dead ahead of time.Crop yield loss 10%-30% is often caused in general plot, reaches more than 70% when serious, even whole strain death.
Root knot nematode mainly survives the winter in soil, muck, invalid body with worm's ovum and 2 instar larvaes, and infect the coming year again, and main some social activity by farming operation tool, seedling exchange, the mankind, water etc. are propagated.Root knot nematode is distributed in 20 centimetres of soil more, and root knot nematode quantity is maximum in 9 centimetres of soil, often be retained in the soil with ovum or 2 instar larvaes with plant residue survive the winter in the muck or when next year, environment was suitable with 2 instar larvaes from tender intrusion, breeding is caused harm.Under no host's condition, can survive 1 year, so thoroughly control is relatively more difficult for protection ground root knot nematode.The harm of root knot nematode has become the outstanding problem in the greenhouse production, and it presents the trend of rising.
The present method of preventing and treating commonly used:
1) nursery bed disinfection:
The seedbed is one of important channel of root knot nematode propagation, if does not handle in the seedbed, be easy to root knot nematode is propagated into the land for growing field crops, the measure of nursery bed disinfection, can adopt following 2 kinds of sterilization methods: the one, nursery soil is concentrated, after dazomet or metamsodium and soil fully mixed thoroughly, it was stifling to cover plastic cloth; The 2nd, after soil turned over, directly sterilize with soil disinfectant.But it is clean that nursery bed disinfection is difficult to thoroughly root knot nematode be removed, and also inevitably brings root knot nematode in the cultivation management process into, influences crop later stage output.
2) resistance stock:
The wild Solanaceae veriety that contains the Mi gene has excellent resistance to root knot nematode.Utilize these kinds to carry out grafting cultivation as stock, can effectively control root knot nematode harm, according to observations, cultivate one batch after, can obviously alleviate causing harm of second stubble crop root knot nematode.But contain the kind of Mi gene when summer temp surpasses 28 ℃, its resistance may be lost, and the kind that contains the Mi gene on the other hand is more expensive, increases planting cost.
3) crop rotation:
Can adopt the method control root knot nematode effect of crop rotation, particularly rice field-upland field rotation better.But crop rotation requires certain plantation and cultivation permissive condition, and the crop of crop rotation should avoid and Curcurbitaceae, Solanaceae and leguminous crop crop rotation, best and gramineous crop crop rotation.
4) soilless culture:
Soilless culture is the important agricultural measures that can effectively avoid root knot nematode to cause harm, adopts the mixture of the peat composed of rotten mosses, vermiculite, perlite, coconut husk usually, and domestic also have commercial matrix to sell.But soilless culture needs supporting drip irrigation equipment usually, and needs good cultivation technique without soil.After the soilless culture 1~3a(), matrix need be changed or carry out disinfection, and changes matrix in a large number and will cause new environmental problem.
5) chemicals treatment or soil disinfection:
For alleviating the harm of root knot nematode, peasant household adopts the higher medicament of toxicity to prevent and treat mostly, though have certain effect, makes the vegetable pesticide residue severe overweight, deterioration in quality, simultaneously severe contamination environment.Cash crop such as Chinese medicinal materials are residual strict to farming, seek the natural phant nematocidal active material, are the developing direction of current root knot nematode control.
As from the foregoing, currently used several method is not ideal.
(3) summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, and the production method of the control soil root knot nematode organic fertilizer of a kind of harm that reduces root knot nematode and volume increase is provided.
The present invention is achieved through the following technical solutions:
A kind of production method of preventing and treating soil root knot nematode organic fertilizer is characterized in that: comprise the steps:
After the peat composed of rotten mosses, Fructus Toosendan, lower molecular weight chitosan and the fertilizer that ferments pulverized the 80-120 order, mix mixture, moisture controlled is below 10%, temperature is 18-32 ℃, add 0.5-1 kilogram gemma Bacillus subtilus by mixture per ton then, mix and place 3-5 days namely, wherein the weight proportion of the peat composed of rotten mosses, Fructus Toosendan, lower molecular weight chitosan, fertilizer is 40:5:2:53.
