First, seed preparation and processing
1. The amount of seed used: 1.25 kg per acre Daejeon (667 square meters).
2. Shaizhong: drying before planting seeds 1-2 days (can not be exposed on the cement floor).
3. Seed Disinfection: Seeds must be soaked with strong Chloride before sowing (see instructions on the medicine bag).
Second, the sowing period, density and planting arrangements
1. Water sowing and watering Seedlings are planted on April 25-May 5th, with a seedling age of 28-30 days. Seedlings are sown on May 1-5 and the seedling age is 20 days.
2. General field planting 48 inches, 5-6 seedlings per acre, acres planted basic seedlings 100,000.
3. Contiguous planting, leaving no flower field.
three. Nurture
1. Retention of Putian: The ratio of Putian to Daejeon is 1:6, and a total of 50 pieces (461 holes/piece) are required for the dumping of acres.
2. Aquaculture dilute sowing: Putian acres sowing 7.5 kilograms, split the scales, quantitative sowing, back and forth evenly sowing, sowing the mud covered seeds, can be covered with grass ash.
3. Putian management: (1) Putian four fertilizers (basic fertilizer, weaning fertilizer, promoting glutinous fertilizer, and delivery of fertilizer) should be given enough. (2) Chemical control: When the seedlings are one leaf and one heart, use 15% paclobutrazol (WP) 100g WP and spray 50kg water to maintain normal surface water after 24 hours.
Fourth, Daejeon Management
1. Apply base fertilizer: a pack of rice special fertilizer per acre.
2. Apply early to promote fattening: after transplanting or planting 5-6 days of standing seedling survival, Mu topdressing urea 5 kg, potassium 2 kg, promoting early delivery, sub-bigger.
3. Clever application of panicle fertilizer, heading at the beginning of flowering to avoid flowering foliar spraying potassium dihydrogen phosphate and urea mixture.
4. Scientific management of water: inch water live seedlings, shallow moisture. When the total number of seedlings reaches 250,000/mu, or when the seedlings are not in season, they should be sown in time, and it is advisable to dry them in the field. From booting to full heading, we inoculated with water and miscellaneous soils, and dried up wet and dry during the later period to keep the fields moist and mature.
5. Prevention of pests and diseases: Insect pests are mainly thrips, aphids, and ticks. Diseases are mainly sheath blight and rice blast. The prevention and control of plant protection station shall prevail.
6. Single income, single drying, single storage, single sale.
