At present, most farmers in the South are working on the sowing and breeding of early rice. It is very important for the management of rice seedlings in the fields and the cultivation of rice bran to achieve high yields of rice. In order to cultivate rice robust, experts proposed field management measures:
When the weather is fine in recent days, it should be covered immediately after sowing to prevent heavy rain or sun exposure.
Seedlings 1 leaf 1 heart period is the first transformation phase of the seedlings fertility process, the focus of the cultivation is to promote the rapid rooting and the formation of a more robust root system, the key measure is to maintain the moisture.
The three-leaf stage is the second transformation period of the seedlings' fertility process. It mainly depends on the nutrition from the endosperm to an independent life. At this time, the seedlings often show a lack of nutrients in the body, and their resistance to low temperatures and diseases is weak. The focus of cultivation is to improve the ability of seedlings to independently produce nutrients. The key measure is to apply “weaning fertilizer†early in the 2-leaf stage to ensure the supply of fertilizer and water.
In case of high-temperature weather, the two ends of the membrane should be uncovered in time to allow the air in the membrane to circulate and prevent the membrane from overheating and cause burning of the seedlings. If the temperature is too low at night, both ends of the membrane should be covered to ensure the temperature inside the membrane. Depending on the weather conditions, such as cloudy and cloudy, timely removal of film and ventilation to regulate seedlings, reduce the temperature and humidity inside the membrane.
Diseases and pests control, common diseases in the seedling stage of the early rice field in our region include bacterial wilt, blight, and albinism. The common pest is Sanhua. In the early stage of onset, the drug can be used in a timely manner, and for the control of bacterial wilt, the drugs such as dextromethorphan, chlorpyrifos, and chlorhexidine can be used; for the control of blight, hymexazol, diclafen, chlorothalonil and other drugs can be used; Trace element fertilizers such as zinc sulphate or ferrous sulphate, or use less fertilizer (especially urea) as basal fertilizer in Putian; prevention and control of Saponin, for the prevention and control of Putian (more than 15 eggs per 10 m2), Use 20% Chlorantraniliprole Suspension (eg KANGCAN), 35% Chlorantraniliprole Dry Suspension (eg ODT), Indoxacarb (eg Kane), and CMC (eg Pleuronate) Wei), 5% buprofen, avermectin (such as the sword), 25% propanthecin (such as manic), flubendiamide (such as ridge song), flubendiamide (such as rice radish) , Toxic high chlorine (such as phlegm killing), chlorpyrifos and other agents according to the instructions for spraying.
Spraying and delivering the drug, and spraying pymetrozine (such as God's covenant, agreement) or imidacloprid (such as ciprofloxacin, trimethoprim), pyrimidazolone plus detox Or virus A or Ningnanmycin or Hydramycin, to prevent the occurrence of rice virus disease.
Transplanting at the appropriate age, 4-5 days before transplanting, no matter what the mode of breeding, we must re-apply the “supplying marrying manure†and insist on carrying the manure under the field.
