7 timely elimination, prevention, treatment, comprehensive control of pest technology
7.1 Seriously disinfect the seeds
Many diseases belong to the seed virus spread, such as rice bakan disease, as long as the seed disinfection to ensure the concentration of disinfectant liquid and disinfection time, you can prevent the disease. In addition, seed disinfection can significantly reduce the occurrence and development of diseases such as rice blast, bacterial blight, and leaf spot disease.
7.2 prevention, comprehensive prevention
The main pests and diseases in the field should be prevented and comprehensively controlled. Such as panicle neck rice blast disease, mainly to grasp the heading period of the break, heading period to fight protective drugs, and in case of rain in time after the application should be supplemented. In short, according to local disease and pest information at that time, early prevention and timely treatment can only do more with less.
8 timely, appropriate, suitable method of spraying 920 technology
8.1 Timely
According to the degree of sensitivity of parents to September 20, the first spraying index was determined. Seed index V20A for the first time, Fengyuan A for 5%~10%, Gold 23A for 15%~20% and T98A for 25%~30%.
8.2 amount
Per acre spray 90% dose: V20A, Fengyuan A 25 ~ 30g, gold 23A is about 16g, T98A is about 12g, the first application of the total amount of 30%, 70% of the total amount of the second spray.
8.3 Law
The first is to look at the weather. Sunny high temperature should be sprayed in the morning or after 4 pm, cloudy days can be sprayed all day, rain and rain days to grab the rain stop spraying; high temperature, windy weather should increase water consumption, rainy days should reduce water consumption.
The second is to see the flowering period. Parents who spent the flower well or the mother's earliest spikes were made according to the best parenting period of the female parents. After the panicles were planted, the trees were planted with 9200; if the parents were eared, they were more than Sub-micro application to promote maternal heading.
In addition, effective use of spikes, yellowing of seedlings, and diseases and pests should increase the amount of 90%.
9 good isolation, impurity removal, preservation three. Guaranteed seed purity technology
9.1 Strict isolation
Natural segregation between the varieties used for production is the use of natural barriers such as hills and villages; or space isolation of more than 100 m; or time isolation, that is, a difference of more than 20 days in the flowering period of different species to prevent biological confusion.
9.2 Strict impurity removal
The first is to remove impurities. Seize the heading period, and remove the maintenance strains of the hybrid strains at an advantageous timing that maintains the strains earlier than the sterile lines, and remove the mutants and other miscellaneous strains after heading.
The second is to eliminate impurities completely. It was found that the panicles were removed without any problems.
9.3 Standard Operation
In the process of collecting, seeding, drying, transporting, storing, processing and packaging of seeds, the parents should be separated from each other, control the whole process, and prevent artificial mixture to ensure the purity of the varieties.
10 Implement prevention, looting, and drying to ensure seed commodity sowing quality technology
10.1 Management Later Defense
That is, in the mature stage of seeding and flowering, we must grasp the management of fertilizer and water, control the amount of 902, and prevent the plants from lodging to cause lodging; use the pesticide in time to prevent and control the diseases and insect pests; Rice smut, prevent seed germination.
10.2 Grab the ripe harvesting period
When the seeds matured by 80%, according to the local weather forecast at that time, they selected clear weather to collect the grain, threshing and sun drying, and prevented the mud from contaminating the seeds during the collection process to ensure the golden color. Advocate early manual removal of the father and use mechanical harvesting to ensure that mature seeds are harvested before the onset of rain.
10.3 Drying after receiving rain
After harvesting and threshing, if it meets rainy days, it must do everything possible to prevent it from being piled up. Make full use of cement, wood flooring, etc. to spread the seeds, vigorously promote bamboo drying seeds and low-temperature drying to reduce moisture, clear sun, ensure seed sowing quality.
It is mainly used in making polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, as solvent for dyes/inks, antifreeze for engine, gas dehydrating agent, manufacturing resin, wetting agent for cellophane, fiber, leather and adhesive. It can produce synthetic resin PET, fiber grade PET namely polyester fiber, bottle chip grade PET for making mineral water bottle, etc. Also can produce alkyd resin, glyoxal, etc., also used as antifreeze. In addition to being used as anti-freeze agent for automobile, it is also used for conveying industrial cooling capacity, which is generally called refrigerant carrier.Ethylene glycol is a useful industrial compound found in many consumer products, including automotive antifreeze, hydraulic brake fluids, some stamp pad inks, ballpoint pens, solvents, paints, plastics, films, and cosmetics; it also is used as a pharmaceutical vehicle. Ethylene glycol has a sweet taste and is often accidentally or intentionally ingested. Ethylene glycol is chemically broken down in the body into toxic compounds. It and its toxic by products first affect the central nervous system (CNS), then the heart, and finally the kidneys. Ingestion of sufficient amounts can be fatal. Ethylene glycol is odorless; odor does not provide any warning of inhalation exposure to hazardous concentrations.
