The rational use of rice transplanting technology is the core, and government investment to guide farmers to purchase is the key. It is not only the current needs of agricultural modernization, but also the objective requirements for the construction of a new socialist countryside. Therefore, we must strictly grasp the technology and policy in the implementation of rice transplanting technology, so as to achieve the purpose of sustained and healthy development.

First, technical clearance
Rice transplanting and seedling raising technology is an agricultural comprehensive technology combining agronomic and agro-machinery technologies. It embodies that agronomic techniques are subordinate to agricultural machinery technology. Only when the two are combined perfectly, can the rice produce high yields, stabilize production, reduce costs, and reduce real costs. Labor intensity of farmers. So technology is the core. According to the conclusions of experts of machine intervention technology and the advanced experience in the field and their own personal experience, they should mainly do the following technical work.
(1) Raising techniques: Normally speaking, the technology of Raising Rakes is the key technical link in the machine-planting of rice, from the preparation of nutritious soil, the flattening and disinfecting of Cibantian, and the cleansing of seeds after germination, and then germination to the dew-whitening and bud-valley landings. Seedlings, water and fertilizer management and pest control must be strictly in accordance with the provisions of the operation, the general floppy disk seedlings field 22 acres per acre, seeding volume must be based on the thousand grain weight provided by the local agricultural sector, that is: the actual number of seedlings / (100% seedling rate of germination rate %) thousand grain weight. The nutrient soil is generally 50 kilograms fine soil after sieving in Daejeon, plus 0.5-1 kilograms of strong Zanthoxylum and mix thoroughly, and prepare 10-15 kilograms of plain soil per mu for cover soil. Chemical fertilizer ingredients. It is important to note that the shoots in the bud valley should be sprayed on the pan before landing to prevent soil worms and earthworms from loosening the roots of the seedlings. Then they are divided into two sides along the center and put floppy disks. Closely, pave the soil with nutritious soil in the pan, then sprinkle the water in the plate and soak the water in the nutritious soil plate. Do not sprinkle water after the sowing and cover the earth and then sprinkle the water, to prevent the emergence of seedlings, uneven, not strong. Sowing should pay attention to uniform, high density, generally 3 grains per square centimeter, the seedling bed cover should pay attention to use wet mud edge to ensure the high temperature and humidity seedlings, seedlings fast Qi. In terms of water and fertilizer management, the requirement is that the water is too little, and the wet seedlings are strong, but the water in the trench can't be too much, which affects the packing. Generally, the leaves are treated with 99% of high-purity potassium dihydrogen phosphate, and every 40-50 grams is watered with 50 water. Kilograms, weaning fertilizers are sprayed, and two-leaf and one-hearted planters are used to ensure that the plant height is 15-18cm within 15-18 days. After the seedlings are transplanted to Daejeon, they are sprayed with insecticides in prescribed proportion within 1-2 days, and then the water should be used to wash the seedlings. To prevent burning seedlings.
(II) Machine insertion technology: The machine insertion technology is firstly based on the shape of the field block to make a reasonable Shimoda, and then “two adjustments and two adjustmentsâ€, ie depth and number of seedlings, are required. For planting. Operators should pay attention to the uniform distance between each trip, and make the same needle after rounding the head. As close as possible to the field hoe, to reduce manual planting.
(III) Field cultivation and management techniques: After the field is cultivated, it should be leveled, then the base fertilizer should be sufficient, the sediment should be planted after 24 hours, and the second is the upper water, drainage, and the drying field. The top dressing can be managed by manual transplanting.
Second, the policy
With the scientific promotion of machine transplanting technology, the state, the province, and the municipality attach great importance to it. The government provides a certain percentage of subsidies for farmers who purchase rice transplanters. Its purpose is to guide and encourage farmers to purchase agricultural machinery, allow farmers to grow good grain with various types of grain, and stabilize the country. Food security, therefore, in the promotion of rice transplanting technology, we must vigorously publicize the state's subsidy policy for farmers' purchases, and be a good adviser to farmers' friends so that they can truly benefit from it. To make full use of the purchased machinery, the agricultural machinery management and promotion departments must formulate a practical and feasible plan. The agricultural machinery manufacturers must also benefit the farmers, especially the after-sales service must be in place. Otherwise, the interests of the farmers will be affected. Food production restricts the promotion of rice transplanting technology.
In short, the rice transplanting machine should really do a good job of the above two points, use scientific and normative technical requirements as a guarantee, and use the state's preferential agricultural policy to drive the rice transplanter technology to develop in depth.
