There are three measures to increase the total rice production. One is to increase the rice planting area, the second is to change the single-season rice to double-crop rice, and the third is to increase rice yield. Raising the yield of rice is the key to raising the total rice production, and it is also an effective measure to increase the benefits of grain production, realize agricultural efficiency, increase grain production, and increase farmers' income. In recent years, the promotion of machine transplanting technology has proven that machine transplanting technology has the characteristics of labor saving, time saving, labor saving, provincial field, low production cost, and increased production and income. However, if technical measures are not in place, it will affect the machine's rice production. How to increase machine insert rice production? According to his own practice of machine transplanting technology promotion, it is necessary to take the following measures and do a good job of "five ones." We will cultivate a seedling and plant a field, use a machine, insert a seedling and manage a field. It is indispensable that they communicate with each other, cooperate with each other, and promote each other. No?t, affect machine insert rice production.
One is to cultivate a seedling. Breeding seedlings is a key technology for machine transplanting. The quality of seedlings is the key to the success of machine transplanting technology. As the saying goes, it's a good half. Therefore, raising seedlings is an important factor in the increase of rice production by machine insertion.
First, the quality of transplanted seedlings. Seedling quality requirements: early rice seedling age 18-20 days, leaf age 3-4 leaves, seedling root stem width 2-2.5 mm, 12-15 shoot roots per plant, good packing, was "carpet", seedling height 12 -15 cm. Seedlings are evenly and neatly arranged with uniform height. There are 2-3 seedlings per square centimeter.
Second, technical measures for childbirth. One must choose a good species. As the saying goes, it is good to plant good seedlings. Therefore, we must select stable and high-yield, disease-resistant pest-resistant, lodging-resistant varieties. Second, we must choose Putian. To choose convenient transportation, convenient irrigation, fertile land, and sunny fields, select 1:10 or 1:100 ratio, select Putian, and do a good job in Putian. Third, we must prepare the materials for breeding. That is, if the bed is to ensure a reasonable sowing amount. The hybrid early rice satisfies 2 kilograms of rice for each mu of field and the fertility period is about 105 days. The seeding rate per acreage is between 180 and 200 grams. Require uniform sowing and broadcast to the corners of the tray. Sixth, it must be carefully managed. For seedlings, technical measures such as scientific fertilization, irrigation, heat preservation and cold prevention, and pest and disease prevention shall be adopted to ensure the quality of seedlings.
The second is to make a good field. A good field is the basis for rice production. Therefore, it is necessary to transplant the planting field in Datian to make intensive cultivation, fat enough field flats, and rotten soil underneath, and the field surface is clean, so that the difference between the height of the field is no more than 3 cm.
The third is to use a good machine. Using a good machine is a good transplanter. Including preparing, adjusting, and operating the transplanter. This is an important part of rice production. First, we must prepare the rice transplanter, and we must maintain it well so that it is in good condition. Second, we must adjust well, and we must adjust the plant spacing, number of plants and depth of insertion as required. Generally have to maintain 18,000 holes per acre, 3 seedlings into 5 seedlings per hole, more than 90,000 basic seedlings, inserted in the depth of 0.5 to 1 cm, so do not drift does not fall. Thirdly, to operate the transplanter, it is necessary to maintain a constant speed, and it is not always possible to stop at a fast pace or stop frequently. During the operation, the route should be kept straight. At the same time do not plug five, encountered windy and heavy rain does not plug, cold and low temperature is not inserted, floating mud does not plug, muddy field does not plug, transplanter does not adjust the plug.
The fourth is to insert a seedling. The quality of machine transplants will directly affect rice yield. Therefore, every seedling should be inserted. The leakage plug rate is less than 5?, the scar rate is less than 4?, the uniformity is greater than 85?, and the float rate is less than 3?.
The fifth is to manage a field. Solve the technical aspects of childbirth and machine transplanting is not a success. What is more important is to strengthen field management after transplanting rice. It is a guarantee for rice production.
The technical measures for field management are: thin water transplanting rice seedlings, shallow water live seedlings, skillful application of fertilizers, eating less and more, timely field drying, seedling fertilization, chemical weed control, pest control and disease prevention.
