Abstract
The present invention discloses a kind of preparation method for the shallot concentrated fertilizer for improving the anti-purple spot of shallot, using zinc dithiocarbamate, dihydromyricetin through soluble small molecule chitosan and spherex under ultrasonic wave after decentralized processing, sustained release disease-control noxa easily absorbed, it is easy to long-time of sustained release disease-control noxa in shallot growth course to absorb, avoid the repeatedly fertilising increase plantation amount of labour, while resistance of the shallot to purple spot can also be improved；And powder is dried to using what Freeze Drying Technique be sustained disease-control noxa, dry rapid, particle is tiny, is not easy to reunite blocking, does not destroy its active component.The present invention is also using edible fungi raw material and clinker mixing addition, the nutrient of abundant concentrated fertilizer, moreover it is possible to improves its fermenting speed, shortens the fermented manure time, improves the preparation efficiency of concentrated fertilizer.
Description
Technical field
The present invention relates to agricultural plantation technology field, and in particular to a kind of shallot concentrated fertilizer for improving the anti-purple spot of shallot
Preparation method.
Background technology
Shallot acrid flavour, slightly warm in nature, have deliver activate yang, seasoning of detoxifying, the various vitamins in shallot can guarantee that human body swashs
Plain normal secretions, moreover it is possible to which effective stimulus sexual desire, so as to " establishing-Yang tonifying yin " establishing-Yang tonifying yin, while shallot is rich in vitamin C, there is diastole
Thin vessels, the effect to stimulate circulation；Pectin contained by chive, the generation of colon cancer is can significantly reduce, there is antitumaous effect.
Allicin in green onion can also suppress the growth of cancer cell；Green onion also contains trace elements of selenium, can reduce the nitrite in gastric juice
Content, there is certain effect to prevention stomach cancer and kinds cancer.
Onion Purple Blotch is the most important disease of shallot.In addition to green onion of causing harm, also cause harm onion, garlic, leek, leaf is mainly encroached on
Piece and bennet, can occasionally cause harm bulb.Early stage, scab is small, slightly concave to fall into, after become larger, ellipse or fusiformis, brown is to purple
Color.The mould layer of raw black on scab when moist, and have concentric wheel stripe, sick portion's frangibility.Scab puce on shallot and onion, greatly
Garlic scab yellowish-brown, dark brown mustiness thing is covered with during high humidity, the shape arrangement of wheel line, grave illness strain leaf and bennet are withered.After cutting top
In semi-humid corruption when bulb and neck are infected, organize to redden or yellow, gradually in dun or black.Storage period can continue to send out
It is rich.
Purple spot germ survives the winter with mycelium in pin main body, on seedling or with invalid body in soil, can continue to for
The green onion of evil storage.Conidium is produced when condition is suitable, is propagated by means of air-flow, rainwater.Invaded from the wound, stomata or epidermis of host
Caused by dye.It is warm, moist to be beneficial to morbidity, the morbidity such as extensive management, impeded drainage, a run of wet weather, density are excessive, growing way is weak compared with
Weight.
Purple spot germ disease time is grown, and easily easily morphs, and waits shallot morbidity to be treated again afterwards and easily carries
The resistance to the action of a drug of high purple spot germ, is unfavorable for the preventing and treating of Onion Purple Blotch.Conventional Onion Purple Blotch protective agents use two sulphur
For medicines such as carbaminate, ammonium sulfate, ammonium chlorides.
The content of the invention
Easily raise difficult questions and control for Onion Purple Blotch in prior art, the problem of germ speed of mutation is fast, the invention provides one
Kind improves the preparation method of the shallot concentrated fertilizer of the anti-purple spot of shallot, and this method fermentation time is short, sustained release disease-control noxa exists
It is unaffected in preparation process, the sub- release time length of sustained release disease-control noxa, Onion Purple Blotch can be prevented and treated for a long time.
The present invention seeks to what is be achieved through the following technical solutions：
The preparation method of the concentrated fertilizer comprises the following steps：
(1) it is put into after mixing zinc dithiocarbamate and soluble small molecule chitosan with water in ultrasonic wave, ultrasound
After processing makes it be uniformly dispersed；Methylene succinic acid, dihydromyricetin, spherex are added afterwards and continues ultrasound, are obtained after drying
Sustained release disease-control noxa easily absorbed is standby；
(2) it is mixed evenly with waste material of edible mushroom, vinasse with water, ferment 24h, and it is standby to obtain composite powder after low temperature drying
With；
(3) magnesium sulfate, potassium hydrogen phosphate, ammonium sulfate, trace element, biological compound fungi agent are mixed evenly and must sought with water
Nutrient solution is standby；
(4) it is standby to obtain activation powder for sealing calcining post activation after vegetation stalk is well mixed with the thick mud of pond sludge or river bed
With；
(5) pulverized after drying leaves of plants and reticulate millettia root, bagasse, sieve, add in step (4) obtained work
Change powder is well mixed to obtain compost, standby；
(6) after activation powder, plant leaf powder, composite powder being mixed evenly with water, compost maturity 20-25 days, spread out
Ventilation is uniformly sprinkled into nutrient solution after drying 3-4d, then admixes sustained release disease-control noxa, stirs, and it is total to adjust moisture
The 24.2~24.5% of weight, afterwards extruder grain obtain a diameter of 2.5~3mm particle.
Wherein, ultrasonic processing method described in step (1) is the ultrasonic frequency ultrasound 1min using 100Hz~200Hz,
Be spaced 30s, repeat 5~8 times, add methylene succinic acid, dihydromyricetin, be ultrasonically treated after spherex be using 100Hz~
200Hz ultrasonic frequency ultrasound 1min, 30s is spaced, repeated 10~15 times.
Dry described in step (1) and dried using Freeze Drying Technique, being dried to it, powder is rapid, and powder size is small, makes
It is not easy activity that is blocking and not destroying each component of reuniting.
Trace element includes copper, zinc, iron, magnesium, copper described in step (3):Zinc:Iron:Magnesium mass ratio is：1:2:5:2.
The waste material of edible mushroom is according to 1:The edible fungi raw material waste material and clinker waste material of 1 ratio mixing.The edible mushroom
Contain a large amount of mycelia and microorganism in raw material waste material, edible mushroom clinker is because by high temperature, its fermenting speed is faster.Edible mushroom gives birth to
Material clinker is used with, is added in concentrated fertilizer, can not only enrich the nutrient of concentrated fertilizer, moreover it is possible to is improved its fermenting speed, is contracted
The short fermented manure time.
Leaves of plants described in step (5) include the leaf of bamboo, pine needle, cloverleaf, lotus leaf, persimmon leaves, one kind in phoenix tree leaf or
A variety of one kind.
According to the shallot concentrated fertilizer of the anti-purple spot of shallot made from preparation method provided by the invention, including matter is pressed below
Measure the component of number composition：3~5 parts of methylene succinic acid, 2~4 parts of ammonium sulfate, 2~4 parts of ammonium chloride, 15~20 parts of plant leaf powder,
