Inserting a small and powerful rice cultivator into the disk-cultivation machine is an important part of achieving high-quality, high-yielding machine-inserted rice. The specific technical points are described as follows: Soil preparation The soil with fertile soil, no wreckage, gravel, weeds and no pollution to the seedlings is selected, and the PH value is 4.5 to 5.5. If there is no such acidic soil, acid can be adjusted with sulfuric acid and nitrohumic acid. To prevent seedling disease such as blight, 50-60 grams of enemy pine are applied per cubic meter of soil. To fertilize the soil, add 200-400 grams of pure nitrogen, pure phosphorus, and pure potassium per cubic meter of disc soil. Mix well and dry thoroughly to facilitate sifting with a sieve with a pore size of 4-6 mm. The area of ​​the net pond per acre needs to be prepared with 20 cubic meters of dried nutritious soil. Seed treatment should be selected for high purity, removal of sorghum branches, germination rate of more than 90%, strong germination potential, spikes and heavy-duty varieties. It is more appropriate for wheat indica rice to be selected as early maturing, medium maturing medium carp or medium carp. Sunny days 2 to 3 days, using mud or salt water selection method to remove empty grains. Diluted 2000-3000 times with 25% Shi Baoke Emulsion, soaking for 48-60 hours, and then wash with water, germination to dew-thickness can be sown. Trampolines require trampolines to be close to Daejeon to facilitate transportation and improve ergonomics. The net ratio of Daejeon is about 1:160. The soil is fertile, drainage and irrigation are convenient, and the ground level elevation is no more than 3 cm. The width of the surface is 1.4 meters, and the width of the groove is 0.25-0.3 meters. It is advisable that the softness is not whited. Each side of the board is 2 meters wide and 1.2 meters wide, leaving 10 centimeters on each side. When placing the plate, ensure that the plate is plastered and there is no gap between the plates. The surface was covered with a film. Mechanical sowing machines can sow soil, spray water, sow seeds, and cover soil once and for all. The sowing efficiency is high and the sowing quality is good. Before sowing, the germinated seeds are properly dried or left in the yarn bag for 1 to 2 minutes in the electric drying machine. It is advisable to sow the seeds. Seeding disc soil thickness 2 cm, cover soil 0.5 to 1 cm, disc soil water requirements were wet state, each dish sowing buds about 0.2 kg, sowing uniform. The Dianchi Lake managed to keep the surface of the soil moist in 1 leaf and keep the temperature at 30°C. At this point, if there is a blade lift, spray can be used to rinse. After 1.5 leaves, the daytime temperature is controlled at 20-25°C, and the nighttime temperature is controlled at about 15°C. It is advisable that the ditch water does not exceed the disk surface. After 2.0 leaves, the bed temperature gradually approaches the natural temperature. In the 2 to 3 days before transplanting, clear the ditch and ditch water to promote the seedlings packing and facilitate the picking and machine insertion. Scientific fertilization When 1 leaf 1 heart of seedlings, each plate (58 cm 28 cm inner diameter) 0.5 to 1 g of urea, 3 to 4 days before the seedlings leave the bed, each plate 1.2 to 1.5 grams of urea, is conducive to normal rice Need for growth and development, easy to machine quickly return to green live tree. For the pest control and pest control, at the same time when applying fertilizer, 20% tricyclazole WP 75 g plus 50% methamidophos EC 100 mg or 18% insecticide bihydrate 200 mg/water 50 kg spray per acre seedbed Diseases such as rice blast, rice blast, etc. are brought into the field. When the machine is inserted into the appropriate period, the seedlings are 2.5 to 3.5 leaves, and when the seedling height is 12 to 15 centimeters, it is necessary to grab the time machine. After more than 3.5 leaves, the quality of seedlings began to deteriorate, and the length of seedlings after insertion was not conducive to early onset.
