Experience of field cultivation and management of rice
Adjust measures to local conditions, manage scientifically, and increase the output per unit area. The following points should be paid attention to in the management of rice cultivation.
1. Timely transplanting: the best season is from May 20 to June 10 in the field.
2. Standard strip planting and reasonable close planting: standard single-row strip planting, north-south direction, plant spacing of 2 × 3 inches, single row planting, uniform planting and shallow planting to ensure that the basic seedlings per mu are within 8-100000 seedlings.
3. Scientific application of sufficient base fertilizer: combined with soil preparation, 1500Mu of rotten farm manure is applied as full-layer deep application, and urea 15kg plus 30% ternary compound fertilizer 20kg as intermediate fertilizer. After transplanting seedlings alive, about 6m / m for 10 days combined with herbicidal application of urea 3m / mu 5kg for topdressing and tillering fertilizer.
4. Timely chemical weeding: reasonable selection of herbicides, combined with topdressing tillering fertilizer, 60% butachlor 75ml plus 10 grams of Caokexin wettable powder, 20 kg of fine soil or 50% Baitianjing wettable powder mixed with soil, it has a good effect on the control of barnyardgrass and gold in rice field. The paddy field water was drained 1 day before application, and the water was rewatered 2 days after application, and the shallow water layer was kept for 7 days.
5. Strengthen the prevention and control of three diseases: focus on the prevention and control of evil seedling disease, rice false smut and bacterial blight. The specific methods are as follows: in the whole growth management, the diseased plants should be pulled out in time and burned: rice false smut was sprayed with Jinggangmycin 3 packets of water 30 kg per mu each time, and sprayed once at booting stage and full heading stage respectively: bacterial blight was sprayed with 25% Ye Kuning or Longke bacteria mixed with water spray at the early stage and full heading stage of the field.
6. harvest at the right time.

Don't forget silicon and zinc when fertilizing rice.
In the optimized formula fertilization of rice, people often attach great importance to the combined application of nitrogen, phosphorus, potassium and other elements, but ignore the application of silicon, zinc and other elements. In fact, rice is a crop that absorbs more silicon, and generally contains silicon dioxide 10 in stems and leaves.
