The currently promoted super rice varieties (combinations) have a long growing period and require more nitrogen fertilizer. In addition, farmers often use too few potassium fertilizers, and some varieties and combinations have genetically inherited indica rice blood. Therefore, compared with other rice varieties, super Rice is susceptible to rice sheath blight, rice blast, and rice smut. Due to the relatively thin planting density of super rice, the large exposed area in the early field, the rapid growth of weeds, and the late growth, it is easy to ignore the prevention and control of rice planthoppers. Rice sheath blight, rice blast and rice smut, and weed and rice planthopper prevention and control methods are described below:
1, throwing or transplanting 5 to 7 days, combined with topdressing, in the throwing of fertilizer in the field of fertilization cast a net of 40 grams per acre, in the transplanting of field fertilizer in per acre 50% Ruifei special 50 ml, Spread evenly to Daejeon, respectively, to prevent weeds. If weeds continue to grow, they can also be used 1 or 2 times as described above.
2.Spray 5% Ruijinte 20 ml +30% Ai Miao 15 ml or 5% Jinggangmycin 50 g per acre at the peak of till till the end of till, dilute 1500 times with water, spray the liquid per acre generally 30 kg. It can control rice sheath blight, rice leaf blast and aphid.
3. At the end of booting (3 to 5 days before the break) and at the beginning of ear, apply 30 ml of Ai Miao once, dilute 1500 times to water, and spray 45 kg of liquid per acre, which can prevent and control rice bran. Disease, sheath blight and rice blast. In case of rain, it is necessary to rush to spray in the falling rain.
4. After heading, depending on the occurrence of rice planthoppers, 3 grams of 5% Acre Chin can be used per acre, and the water is diluted 1500 times. Generally, 45 kg of liquid medicine is sprayed per acre, which can prevent rice planthoppers. There are many ways to control rice planthoppers and control pest occurrence 1 or 2 times.
Super rice other pests and diseases can be integrated and controlled with reference to general rice pest control methods.
