Early rice intensive breeding, cost-saving and efficiency increase
In 2012, it was the first year that the country implemented the technology of intensive rice breeding for early rice (ratoon rice) nationwide. Early rice seedlings (ratooning rice) concentrate on breeding, which can avoid natural disasters, solve the shortage of rural labor force, and farmers' difficulties in raising children. It is necessary to restore the development of double-season rice, realize cost-effectiveness, and increase farmers' income. The key techniques for early rice (Rice Rice) breeding and breeding are as follows: First, prepare bed soil 1. Soil quality requirements: vegetable garden soil, cultivated dryland soil, winter ploughing, winter plowing, paddy field soil, or winter muddy pond soil. After ploughing and thinning, it is matured and then used. 2, bed soil smash: bed soil required for 1 ~ 2mm, sieving. After sieving, 100 acres of qualified bed soil are reserved per mu of field soil, of which about 70 are fertilized, disinfected, and acidified to make nutrient soil (subsoil), and about 30 are directly used as cover soil. 3, nutrition soil production: 1 fertilization. If the preparation time is short, fertilization is not recommended when making nutritious soil. 2 disinfection. Each 100kg of nutrient soil with 40 grams of enemy pine or transplanting spirit 3 ~ 5ml for pouring, mix well, heap stuffy 20 hours. 3 adjust the acid. Rice seedlings are suitable for growth in soils with a pH of 6.3 to 6.5. Second, seed germination General machine seedlings use seed 1.5 mu per acre, placed in 35 °C ~ 36 °C germination room, germination 12 ~ 15 hours, germination to break the chest exposed white is appropriate. Third, batch sowing The mechanical age of transplanting machines is small and elastic. The sowing date must be calculated according to the age of 15 to 20 days. If the machine is transplanted with a large area, the seedlings should be planted in batches according to the planting schedule to ensure proper age transplanting. In general, each walk-in transplanter inserts 10 mu per day, and a high-speed rice transplanter inserts 30 mu per day, one batch every three days. Sowing sowing requires uniform sowing, each shoot sowing valley 80 to 100 grams. After sowing, it is better to cover 0.3~0.5cm cover seed soil with no seedlings. Before sowing, the bottom soil must be sprayed with enough water to ensure the seedlings. Fourth, greenhouse management The indoor thermostat is generally maintained at a temperature of 30°C to 32°C in the upper truss for 1 to 2 days. In the first 3 to 4 days, the temperature is maintained at 28 to 30°C, and the temperature is lowered to 25°C in the 5th day. The chamber is opened for 6 to 7 days. . The humidity in the greenhouse should be kept above 90%. V. Sending the management of Putian 1. Sending fields to prepare for the field: According to the ratio of 1:100 in Datian, you can leave Putian. 10 days before sowing, you can drive in the fields in Sheung Shui, Sheung Shui. Car surface specifications: The car is 1.4 meters wide, 0.3 meters wide, 0.2 meters deep, surrounded by a good open ditch. After the car drains the car, fill the cracks. 2, seedling management: First, water management. The seedlings maintained flat ditch water before the three-leaf stage, so it was mainly wet. If there is a nourishment at the noon of the sunny day, the leaves shall be filled with thin water to protect the seedlings, and in the rainy days, the gutters shall be drained; if the seedlings encounter strong cold air, they will invade. To nurse the waist water protection seedlings, warm water after changing seedlings; second is to early weaning fertilizer. Before the machine is inserted, it must be followed by weaning fertilizer in a timely manner. The application of weaning fertilizer should be carried out according to local conditions such as soil fertility, age, and weather characteristics. Generally, 10 man-to-be urine per acre with decomposed human excrement, 20-ton water or urea 5.0 ~7.0? Water 500?, in the evening when the seedlings poured water dew. The third is to do a good job of pest control. The main control of rice thrips, seedling blight, aphids and so on. Sixth, transplant preparation 1. Timely water-controlling of seedlings: 3 to 5 days before transplanting, the water-controlling seedlings will be kept, and on sunny days, the water will be maintained in half ditch. If the seedlings are rolled at noon, they can be treated with watering and moistening. Rainy weather should drain the sulcus of water, especially before planting seedlings, cover the rain before rain to prevent excessive water content in the soil (bed soil). 2, adhere to the transplanting with drugs: before planting a pharmaceutical control. 1 to 2 days before planting were sprayed with agents such as Kang Kuan, Dao Teng, and Long Feng. 3, see Miao Shi sent to marry fertilizer: generally carried out in 3 to 4 days before transplanting, leaf color fading delittle seedlings, mu urea 4 ~ 4.5? Duishui 200? Evenly spray or pouring in the evening, after application To sprinkle a clean water to prevent fertilizer damage and burning seedlings; leaf color is normal, leaf upright but not under the seedlings, acres with urea 1 ~ 1.5? Watered 60 ~ 70? For extra-root spray; leaf color green and leaves under the Phi Seedlings, do not apply fertilizer, water control measures should be taken to improve seedling quality. 4. Proper shipment: The shipment of machine transplants should minimize the number of shifts of the block and ensure the size of the block, so that it can be carried forward, shipped, and planted. Places where conditions permit can be transported to the field heads with the flats, or they can be rolled up carefully after the start of the market. Stacked on the trucks, stacking layers are generally 2~3 layers. Transportation to Tiantou should follow suit. Remove the flat, which will facilitate machine insertion.
