As the saying goes, “three minutes and seven minutes,†the crucial period of the current mid-term management of upright rice, the timely application of management measures will have a direct impact on the development of rice traits, yield, and quality. At present, water and fertilizer management, weed control, and disease prevention are important links in the mid-term management of rice. So how do we fill water, apply good fertilizer, remove good grass, and prevent disease? First, timely chemical weeding or physical weeding. According to the growth of rice in the field, weeding herbicides or weeds were manually removed. Second, scientific fertilization. 1. Grab the diversity of fertilizers. Due to the fact that the transplanting period of rice in some areas is generally delayed compared with the normal years, the age of the larvae is larger. Therefore, the transplanted rice should be applied with tiller fertilizer and increase the amount of fertilizer, and the amount of nitrogen fertilizer must be increased by about 10% to about 20% over the year to promote the tillering and prevent the occurrence of early spike. 2, depending on the seedlings strong stalk manure. For paddy fields with leafy green leaves and flat or drooping leaves, only potash fertilizer or no nitrogen fertilizer is applied to the paddy field where rice leaves are flat green or drape. For the paddy fields with a small amount of fertilizer and normal color turning of the leaves in the early stage, appropriate nitrogen and potassium fertilizers are applied. Third, reasonable irrigation. Irrigation principles: Shallow water promotes squatting, inch water live trees, thin moisture pods, hoe enough to dry the field, deep water escort, dry and wet strong seeds. Achieve high-yielding appearance of Yeqingxiu, yellowish-green, and large-grained grain. Fourth, to strengthen pest control of pests and diseases. 1. Rice blast: In the early stage of leaf blast, 40% thiocyclazole in mu, 150g/mu or 75% tricyclazole 20-30g/mu, or 40% of Fuji No.1 EC 100ml, add water 40~50 Kilo uniform spray. 2. Rice smut disease: 10 to 20 days before heading, use 20% Jinggangmycin 50 grams/mu to control. 3, bacterial leaf blight: with 25% Ye Kuning 100-150 g / mu or Kuguning 100g / mu watered 60 kg spray control. 4. Sheath blight: At the end of childbirth, when the incidence of plexus reaches more than 5%, the use of Jinggangmycin wettable powder 5 grams or 25% Triadimefon WP 50 grams of water plus 40-50 kilograms of spray per acre, the key spray rice Lower blade. 5, rice borers: the appropriate period of control is the period of childbirth, from the damage rate of 1% or more when the drug control. Control methods: Each mu can choose 20% triazophos EC 100 ml or 90% crystal trichlorfon 200 g, 25% insecticidal water 200 ml, 80% insecticide 50 g, add water 40-50 kg spray. 6, rice planthoppers: when 10 worms and more than 50 when the timely medication control, per acre with 10% imidacloprid WP 30 g or 80% dichlorvos 100 ml, 25% bufalin 20 g water 40-50 kg spray . 7. The rodent pests were treated with bromadiolone poison baits.
