Potato late blight is a pandemic and devastating disease. It has become a major factor that restricts the healthy development of the potato industry. It should be based on the promotion of disease-resistant varieties and virus-free seed potatoes, focusing on seed potato treatment and chemical emergency control. Comprehensive prevention and control technology supplemented by fitness cultivation will control the damage rate of potato late blight within 10%. Virus-free and disease-resistant varieties were used to establish a virus-free seed potato breeding system and a disease-free seed-retention base was established. Remaining farms should be more than 2.5 kilometers away from Daejeon. Strict management measures must be taken and singles must be collected. Select disease-resistant varieties according to local conditions. Seed processing promotes the sowing of small sweet potatoes. Before cutting the chips, the cutting knife is soaked with 75% alcohol solution, 0.1% potassium permanganate or formalin solution. Before seeding, use 68% of the weight of the seed potato, 68% refined arsenic manganese zinc wettable powder or 72% cream urea manganese zinc wettable powder plus appropriate amount of plant ash or gypsum powder and mix evenly. High ridge cultivation promotes high ridge cultivation, especially in areas with high rainfall and good sensation, ridging or ridging after flat sowing can be adopted to reduce the bacterial growth rate of tubers. Cultivate disease avoidance and reasonable close planting, budding stage control plant leggy. Timely sowing, rational rotation, to avoid continuous cropping or interplanting with Solanum and cruciferous crops. Chemical prevention and treatment before the onset of budding should be promptly removed from the diseased plant and brought out of the field for destruction. The spraying of the plant within 50 meters around the diseased plant should be controlled every 7 to 10 days, with 3 to 4 injections. After the onset of budding, selective methocarbazone, propamocarb hydrochloride, methionyl zinc, fluorophyrin, prophylactic and
Other fungicidal sprays can be used, taking care to alternate medication. From the bud to the initial stage of flowering, spray the 2nd mancozeb, propylenzinc, dinynobactam, chlorothalonil and other protective fungicides before the onset of continuous rain. Harvest and storage period control disease 1 week before harvest, the stems and leaves will be cleared out of the field and concentrated. Harvest on sunny days to avoid injury to the skin of the tuber. Remove the diseased potato and wounded potato pieces before entering the pit, and store them in a cool, ventilated place for 3 days. Before storage, tobacco smoke was sterilized with sulfur or 15% Pythium chlorothalonil. Storage is controlled within two thirds of the storage capacity. Increase ventilation during storage period, temperature not lower than 4°C, humidity not higher than 75%.
Bagging Scale sytem
Bagging Scale System is suitable for
packing open-mouth bags, after filling the material, the system will sew or
seal the bags. It has a widely filling weight ranging depend on the customer`s
request and weighting sensor.it is usually used in a complete plant, to pack
the cleaned seeds. It has an ideal weighing system by adopting advanced
microelectronic technologies; it provides perfect control and management of the
weighing and packing process.
It's suitable of packing the granule materiel,
such as the seed, agricultural product and chemical etc.
Advantage:
High
calculating precision, rapid packaging speed, stable function, easy operation.
Adopt
advanced techniques on control instrument, sensor, and pneumatic components.
Advanced
functions: automatic correction, error alarm, automatic error detection.
All
components which have direct contact with bagging materials are made from
stainless steel.
