2011 Rice Production Technical Measures
Rice is the main food crop in Xiangyun County, accounting for 35% of the total sowing of the spring crops. The total production accounts for 40% of the total grain production in the spring and plays a decisive role in grain production. The rice in the county belongs to the warm and cool rice cultivation area. The lack of heat resources and late spring and cold temperatures are the bottleneck restricting rice production in August. On the basis of summing up many years of experience, we should grasp the following technical measures:
First, sowing season: Master the age of 40-45 days. Sowing from March 15 to March 20 and transplanting from May 1 to May 10.
Second, nurture the strong and strong:
1. Seedbed selection: Choose low-lying water table, flat terrain, sunny leeward, convenient water source, fertile soil, and no acidic or acidic vegetables or irrigated land.
2. Seed bed fertilization: One month or earlier before planting, apply 5-8 kg of high-quality rotten manure (screening) per square meter of seed bed to excavate in a 15 cm plowing layer, and watering the fermentation. Fertilizer, increase soil organic matter, improve permeability. (Forbidden use of unripe farmland fertilizers, coal ash, plant ash, etc.)
3, seedbed finishing: digging broken clams before sowing, removal of impurities, when the construction of the bed using high and low eaves, the seedbed width of 1.4 meters is appropriate, in order to operate. After leaving a good cover soil, transplant seedlings with 20-25 m2 of seedlings per acre, 2.5 kg (1 bag) of Shi Zhuang Miaojin, 3-4 kg of rice-specific compound fertilizer, and evenly plowing about 10 cm. In the layer, after the leveling, irrigated with water for soil disinfection, fertilization and acid adjustment.
4. Seed treatment: Soaking seeds for 1 to 2 days before sowing to increase the germination rate. Choose salt water or muddy water (concentration: 12%, use fresh eggs in salt water or muddy water, and expose the eggs with 2 cents of coins), remove empty impurities, rinse with water, and soak in seeds with 2000 times solution of Schmok 2000 hours. Can sow.
5, seed film, sowing rate of 90 to 100 grams per square meter is appropriate, sowing should be fine sowing, in order to facilitate the cultivation of strong, sowing after suppression, so that the seeds into the ground on three sides and cover a fine tidal After the soil is removed, covered with loose wool (forbidden use of straw), covered with membranes and pressed tightly.
6, seedling management: If the temperature is high (super 40 °C) after sowing began to sprout a small amount of air, see the green after the air curing seedlings 3? 5 days, 2.5 leaves when the film, uncover the film after the water dripping, after the dry when poured Permeable, do not water. Poorly-fertile plots can be used with 100 grams of compound fertilizer per square meter at the 3-leaf stage. Artificial weeding before planting once to prevent rice blast.
Third, Daejeon transplanting:
1. Fertilization: 1000-1500 kg of high-quality rotten manure in Mushi when turning over the field, 40 kg of compound (mixed) fertilizer (N13:P7:K5), 5-7 kg of urea, 2 kg of zinc sulfate Middle-layer fertilizer, artificial fine leveling, transplanting.
2.Specifications: When transplanting, it should be transplanted with soil, and the pulling rope should be inserted in a shallow row with a row spacing of 23 cm, a cluster spacing of 10-13 cm (ie 73 inches or 74 inches), and 2-3 seedlings per ridge, basic seedlings per acre. 5-6 million seedlings.
Fourth, Daejeon Management
5-7 days after planting except one time, keep shallow water management to increase water temperature and promote early growth. After the peak period of tillering, according to the situation, the field is cultivated in proper time and the booting season is treated with low temperature and water to protect the seedlings. During the mature period, the wet management will be carried out to increase the spike success rate and the seed setting rate. From booting to heading stage, 75% of tricyclazole was used to control the blast stalk blasts. Harvested in a timely manner, has achieved increased production and income.
