Ecological regulation:
1. Rotation changes
Round with other departments.
2. Clean the countryside
Clear weeds around the fields and surroundings, overturn the land to destroy the winter places of the diseased insects, and reduce the base and insects.
3. Fine and neatly
1) Soil disinfection
The plot of the soil -transmitting disease can be reached 25cm deep in the summer high temperature season, sprinkled 500kg of straw or wheat straw per 667 m2, adds 100kg of calcium calcium calcium, mixed after mixing the ridge. Essence
2) Disinfection of the shed
500 times the liquid of 50%multi -bacterial wettable powder, and disinfect the shed, ground, roof, wall surface and agricultural tools.
4. Fitness cultivation
1) Choose a variety of disease resistance
Based on local diseases and insects, we choose to resist disease -resistant varieties, such as Luqing 7 and Gold Sweet King.
2) Seed disinfection
Winter soup soaking seeds: Pour the seeds into the warm water of 55 ° C and keep stirring until the warm and cooling dry. Use 10 billion live spore/g deodori bacteria 100 times liquid to prevent anthracnose.
3) Grafting
Generally, insertion method, special white seed pumpkin rootstock.
4) Soil treatment
Use each acre before planting> 500 million/G Berbalus+Jelly -like Bacteria 10kg to improve the soil ecology and prevent soil diseases such as withered disease.
5. Immune -induced resistance
After the seeds come out of the seedlings, spray 5%amino oligosaccharide 1000 times liquid every 10 days, and spray a total of 2-3 times.
Biological control:
1. Biological bacteria
1) Use 0.30 billion/mL waxybillarhbin to prevent smoke.
2) Point Dan Zi Zi Zimi 800-1000g/667m2 to prevent root width.
3) Prevention, disease, and gray mold diseases such as Bacillusbalulholia Bacteria.
2. Natural enemy harm
1) Tobacco mels: Little aphid bee began to release within one week of planting. Generally, 2000-3000 bees are placed per 667m 2 times; when the single-strail annihilation is more than 10, it can be used once to prevent the base and lower the base. After 7 days, put the bees 2-3 times.
2) Thrus: The small flowers are released in the early stage of the occurrence, and the release amount is 300-600 heads/667 m2. It is released again after 10 days, and a total of 2-3 times.
3) Red Spider: The use of Chile's small Zhi Sui mites every 667m210000-15000 is released in the early stage, and it is released every 7-10 days until the production is over.
3. Disease prevention and treatment
Leaf spots: 300-500 times liquid spray can be sprayed with 10 billion/ml polyticobacteria.
Gray mold: Bacterium Berbalobacteria+10%more anti -moldycin spray.
White powder: 150-200 times liquid of 1%mulcin water, or 10%Ningnandin soluble powder 1200-1500 times solution, or 8%pyrine nucleoside antibacterial powder 500-750 times liquid spray.
Scientific medication:
1. Sudden disease: 800 times the solution of 72.2%creamy mildew, or 10%benzoxyl methamphetamazole decentralized agent 2000 times liquid.
2. Veteomy: 800%liquid of 70%nailobooprotic wettable powder, or 46%copper hydroxide, or 6.25%villain ketone+62.5%of the alex manganese zinc spray.
3. White powder: Use 25%sarcolus SC34g/667m2, or 10%benzene methyl acetazole 1000 times liquid spray.
4. Anthrax: 62.5%of the manganese and mangible mangated wettable powder at the beginning of the onset of 600-800 times, or 6.25%villainone ketone+62.5%decentralized granules of manganese zinc water, 1500 times 25%metericine milk oil 2000 times liquid.
5. Root nematodes: 1.8%Avinin or 41.7%fluorizidamide SC can be used to treat soil.
