Rice transplanting characteristics
Rice transplanting characteristics:
1. Better mechanical properties. In the 1960s, the rice transplanter was developed for the characteristics of root-washing seedlings. When the machine was inserted, the claws could not be controlled freely, which affected the uniformity of planting, the high rate of scars and the rate of scars, and the quality of planting was not high. Adapt to the requirements of rice production. Now promoted PF455S hand-held rice transplanter, P600, RR6 high-speed rice transplanter, are introduced from foreign advanced technology, combined with China's rice production practice, optimized design, development and production, with mechanical reliability, adaptability, stability, The performance of the work, the quality of the work and the speed of the work are greatly improved, fully meeting the requirements of modern agronomy.
2. There are major improvements in the breeding method. In the past, the machine was transplanted with conventional seedlings, and the seedlings were transplanted with roots. The standardization was low, the labor was time-consuming, the operation was cumbersome, and the technical model of manual insertion was never obtained. Nowadays, the new machine transplanting technology promoted, based on the absorption of foreign factory cultivation technology, the use of plastic floppy disk breeding, medium and small seedlings with soil transplanting, the ratio of 秧 达 to 1:100, a lot of savings in Putian. The tray used in the nursery is flat, the seeding amount and the sowing depth are easy to grasp, and the breeding is safer. The machine transplanting has less labor, higher work efficiency, greatly reduced the cost of breeding, and is more suitable for future commercialization and industrialization. At present, the fully automatic breeding line of the supporting and promoting is easy to operate, uniform sowing, good seedling quality and high working efficiency, which has become a powerful driving force for machine insertion and promotion.
3. Technical indicators are easy to control quantitatively. The new rice transplanter can quantitatively adjust the technical indicators such as basic seedlings and planting depth, and truly realize the expansion and seedling planting. Such as PF-455S rice transplanter, each 120cm, fixed to 4 rows, line spacing is 30cm. The plant spacing can be adjusted to 11.7, 12, and 14.6 cm. The density of planting per acre is 1.4, 1.6, and 18,000 points respectively. By adjusting the horizontal and vertical feeding mechanism, the number of seedlings per hole is adjusted to 3-5 seedlings, so that the basic seedlings per acre are controlled at 50,000-80,000. The basic seedlings that have been difficult to control in production have been greatly reduced, and the “small group and strong individual†have been realized, which has laid a good foundation for the quality control of rice population. The current rice transplanter is also equipped with a hydraulic profiling device, which can undulate up and down the surface of the field, constantly adjust the state of the body, keep the balance of the body and the planting depth consistent, greatly improving the quality of planting. In addition, the seedlings are planted with soil, the plant injury is small, the seedling period is shorter, the seedlings are early, and the seedlings are quick.
4. The increase in the cost of the festival is significant. The new machine insertion ratio is 1:100, which is one-third of the throwing (1:30), which is one-fifth of the conventional hand-planted hoe (1:6-7), which greatly saves the battery. Save irrigation water. The basic seedlings per acre are reduced to 50,000-80,000, and the amount used is reduced by one-third. The pan, nutrient soil and mulch film have been reduced by half, and the labor is also reduced accordingly. According to preliminary estimates, the machine transplanting is more than 50 yuan per acre, and the economic benefits are significant.
5. Adapt to the transfer of labor. The new machine transplants labor saving, saving, saving Dianchi, and supporting automatic breeding line, which is very suitable for factory, intensive, specialization, commercialized breeding, suitable for industrial operation. At present, the machine transplanting professional households from the breeding to the machine transplanting, 60-100 yuan per acre field. And the cost of a farmer's seedlings, seed, seedlings, nutrient soil, fertilizer, pesticides, water and other materials and breeding, throwing, costing more than 150-200 yuan per mu. The farmers saved the cost and saved the Dianchi Lake, freeing up time and energy. The promotion of rice transplanting has pushed the commercialization, industrialization and socialization services a big step forward, and truly realized the transfer of labor.
6. It is an inevitable outcome of social development. With the development of society, the problem of population aging has become increasingly prominent. The only child has become the main labor force of the society, and the number of people engaged in agricultural production is becoming less and less. With the continuous improvement of the land transfer mechanism, the contracting of one-family rural joint production will gradually become a contracted operation of a small number of agricultural machinery, factory, specialization, intensive breeding, large-scale mechanized transplanting will become the inevitable rice production, once again Promote the revolution in rice cultivation methods.
