Description
Technical field
The present invention relates to agricultural technology field, the method for treating seeds of cucurbita pepo seedling rot is specifically prevented and treated.
Background technology
Cucurbita pepo belongs to 1 year sound sprawling herbs of Curcurbitaceae Cucurbita, North America south is originated in, in the middle of the 19th century
Start to introduce Chinese cultivated from Europe, there is cultivation all parts of the country.Cucurbita pepo contain abundant vitamin C, glucose etc. other
The content of nutriment, especially calcium is high, have effects that relieving restlessness quench the thirst, moisten the lung and relieve the cough, reducing fever and causing diuresis, dispersing swelling and dissipating binds, moreover it is possible to
Increase immunity, secretion that is antiviral, antitumor, promoting insulin in human body prevents and treats diabetes, and prevention liver-kidney diseases become, enhancing
The effect of liver and kidney cells power of regeneration.
Cucurbita pepo seedling rot is also known as root rot, wilt disease, is caused by Fusarium oxysporum and Phytophthora nicotianae Breda, and the disease generally exists
There is symptom in florescence, continues up to and uproots plants after their edible portions have been harvested, and the disease causes plant withered and dead, and 70%- is up in the seriously incidence of disease
90%, the disease has turned into the key factor of the plantation of restriction cucurbita pepo and development, and the preventing and treating of current seedling rot is still anti-with chemical pesticide
Based on controlling, mainly prevented and treated in the site of pathological change sprinkling chemical pesticide of period of disease, but because the toxicity of chemical pesticide is big, residual
Amount is high, adds the evening in period sprayed, causes the pesticide residue in edible cucurbita pepo exceeded, seriously endangers health, and dirty
Contaminate environment.At present, it is badly in need of finding a kind of free from environmental pollution, small toxicity, residual quantity is low, and can delay the drug-fast production of crop
It is raw, Pesticide use amount and access times are reduced, reduce the method for agricultural cost to prevent and treat the seedling rot of cucurbita pepo.
The content of the invention
It is an object of the present invention to provide one kind it is free from environmental pollution, small toxicity, residual quantity is low, and crop can have been delayed drug-fast
Produce, reduce Pesticide use amount and access times, reduce the seed treatment side of the preventing and treating cucurbita pepo seedling rot of agricultural cost
Method.
In order to achieve the above object, the present invention uses following technical scheme.
1) seed disinfection：Choose full, not damaged, the cucurbita pepo seed that nothing is gone mouldy, purity is high and dry 1-2d under the sun,
Then it is placed in the trisodium phosphate solution of 4% sodium chloride+10% and sterilizes after 20-30min, is rinsed well, dried in the air naturally with clear water
It is dry；
2) Chinese herbal medicine fluid is soaked seed：Sterilized seed is immersed in mixing Chinese herbal medicine liquid after 12-18h, rinsed with clear water
After clean, dry naturally, described mixing Chinese herbal medicine is by weight：5-6 parts of the Chinese bulbul, 3-4 parts of the root of langdu, Radix Isatidis 8-10
Part, 7-8 parts of folium isatidis, 8-10 parts of purslane, 7-8 parts of radix scutellariae, 3-4 parts of sida szechuensis matsuda, 5-6 parts of Chinese lobelia, 1-2 parts of lancea tibetica, open country
2-3 parts of sweet osmanthus, 2-3 parts of suchow mosla herb, 3-4 parts of operculate cleistocalyx leaf, 2-3 parts of Chinese tallowtree leaf, 3-4 parts of speedwell, said herbal medicine is added water use
Small fire is boiled after 2-3h, the Chinese herbal medicine fluid that filter and remove residue is mixed, 1kg seeds decoction 40-60g, and decoction is diluted into 50-60
Soaked seed after times；
3) dressing seed：Sowed after above-mentioned treated seed is dressed seed with seed dressing, described seed dressing is by weight
Measuring number is：3-4 parts of chitosan oligosaccharide, 0.5-1.0 parts of fulvic acid, 0.8-1.2 parts of uniconazole P, 3-4 parts of ABT root-inducing powders, Propamocarb salt
1-2 parts of hydrochlorate, 1-1.5 parts of glycine betaine, 1-1.5 parts of chitin, 0.8-1.2 parts of rosin diene, 5-6 parts of metalaxyl, the seed dressing
The preparation method of agent is：1. following components, 3-4 parts of chitosan oligosaccharide, 0.5-1.0 parts of fulvic acid, alkene effect are weighed respectively by weight
0.8-1.2 parts of azoles, 3-4 parts of ABT root-inducing powders, 1-2 parts of propamocarb, 1-1.5 parts of glycine betaine, 1-1.5 parts of chitin, rosin
0.8-1.2 parts of diene, 5-6 parts of metalaxyl；2. uniconazole P, rosin diene ethanol are dissolved, dissolving ratio is 1g medicines 2-
3ml ethanol dissolves；3. by chitin acetic acid, dissolving ratio is 1g chitins 2ml acetic acid；4. it is shell is few
Sugar, fulvic acid, ABT root-inducing powders, propamocarb, glycine betaine metalaxyl water dissolve, and dissolving ratio is the matter of water and medicine
Amount is than being 2:1；5. the medicine 2., 3., 4. step dissolved is mixed, after being sufficiently stirred for, and is made into seed dressing agent solution and is carried out
Sowed after seed dressing, seed dressing 1-2h, the mass ratio of seed dressing and grain weight is 1：120-150.
The advantageous effects of the present invention：The inventive method can prevent and treat a variety of pest and disease damages of cucurbita pepo, especially to cucurbita pepo
Seedling rot has good prevention effect, and with degeneration-resistant, strong sprout effect, greatly increases the yield and product of cucurbita pepo
Matter, meanwhile, this method delayed crop it is drug-fast generation, reduce Pesticide use amount and access times, reduce it is agricultural into
This, and persticide residue is extremely low, beneficial to environmental protection.

Experimental example
Test and carried out in 2016 in Minqin modern agriculture demonstration zone, 3 each processing, processing 1 are set altogether：Any place is not done
Reason, is used as blank control, processing 2：Cucurbita pepo period of disease conventional 500 times of liquid irrigating roots of medicament carbendazim, processing 3：Embodiment
3, arranged using random district's groups, 3 repetitions, plot area 10m2, using conventional field management, withered seedling is investigated in the phase of uprooting plants after their edible portions have been harvested
Rate, the prevention effect of seedling rot, and determine the yield of cucurbita pepo.
The prevention effect (%) of seedling rot=[seedling in (the withered rate of seedling after the withered rate-processing of seedling in control field)/control field is withered
Rate] × 100.
As can be seen from Table 1, the inventive method embodiment 3 prevents and treats seedling rot to the prevention effect of cucurbita pepo seedling rot than conventional
The prevention effect of 500 times of liquid irrigating root processing of medicament carbendazim of disease is high by 29.7%, and yield is high by 22.6%.
Prevention effect and yield of the different disposal of table 1 to cucurbita pepo seedling rot
| Processing | The withered rate of seedling (%) | Seedling rot preventive effect (%) | Yield (kg/ mus) |
| Processing 1 | 11.8 | 2200 | |
| Processing 2 | 5.4 | 54.2 | 3100 |
| Processing 3 | 1.9 | 83.9 | 3800 |
