First, the characteristics of rice transplanter
1, better mechanical properties. The rice transplanter of the 1960s was developed for the characteristics of the root wash seedlings. When the machine was inserted, the claws could not be controlled freely, which affected the evenness of the planting, the hooking rate, and the high rate of scars, and the quality of the transplanting was not high. Adapt to the requirements of rice production. The now popularized PF455S walk-in rice transplanter, P600, RR6 high-speed rice transplanter are all imported foreign advanced technology, combined with China's actual rice production, optimized design, development and production, with mechanical reliability, adaptability, stability, Job performance, job quality and job speed are greatly enhanced, fully meeting modern agronomic requirements.
2. There are major improvements in the way of childbirth. In the past, machine seedlings were transplanted using conventional methods, with large seedlings washed and transplanted, with low standardization, time-consuming and time-consuming operations, and cumbersome operations. They had never been able to get rid of the manual transplanting technique. The new machine transplant technology now being promoted, based on summarizing the techniques of absorbing foreign factory-based planting techniques, uses plastic floppy disks to grow oysters, transplants small and medium-sized seedlings with soil, and has a ratio of 1:100, which saves a lot of Putian. The seedlings used in the breeding school are flat and the seeding rate and seeding depth are easy to master and the breeding is more safe. Machine seedlings are sown with less labor, high work efficiency, and greatly reduced the cost of raising seedlings. They are more suitable for future commercialized breeding and industrialized operations. The currently-supported and fully-automated childbirth lines are easy to operate, uniform in seeding, and have good seedling quality and high work efficiency, and have become a powerful and effective driving force for machine transplanting.
3, technical indicators easy to quantitative control. The new rice transplanter can quantify 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 in 4 rows, spacing 30cm. The plant spacing can be adjusted to 11.7, 12, 14.6 cm. The planting density per acre was 1.4, 1.6, and 18,000 holes, respectively. By adjusting horizontal and vertical feeding mechanisms, 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 groups and strong individuals†have truly been achieved, laying a good foundation for achieving quality control of rice populations. The rice transplanter is also equipped with a hydraulic profiling device, which can follow the ups and downs of Daejeon's surface and continuously adjust the state of the body, keeping the body balance and planting depth consistent, greatly improving the quality of planting. In addition, the seedlings are planted with soil, the planting injury is small, the seedling period is short, the seedlings are early, and the seedlings are fast.
4. The cost of this project is significant. The new machine has a transplant ratio of 1:100, which is one-third of the throw (1:30), and is one fifteenth of the conventional hand-planting rake (1:6-7), which significantly saves Dianchi Lake. Save irrigation water. The basic seedlings per acre fell to 50,000 to 80,000, and the seed use decreased by one-third. The plate, nutrient soil, and plastic film have all been cut in half, and the number of workers has been reduced accordingly. According to preliminary estimates, machine-planting transplants will increase income by more than 50 yuan per hectare, and the economic benefits will be significant.
5, adapt to the transfer of labor. The new machine-planting workmanship, cost-saving, save Dianchi pool, supporting automatic breeding line, is very suitable for industrialization, intensive, specialized, commercialized breeding, suitable for industrial operation. At present, special machines for transplanting rice seedlings are transplanted from seedlings to machine transplants, charging 60-100 yuan per mu of Daejeon. For the one-for-one seedling and seedling planting, the cost of farmer households on seed, seedlings, nutrient soil, fertilizers, pesticides, water and other materials and breeding and throwing seedlings will be more than 150-200 yuan per mu. Farmers saved costs and saved Dianchi, freeing up time and energy. The promotion of rice transplanting machines has taken a big step forward in commercialized breeding, industrialized management, and socialized services, and has truly achieved the transfer of labor.
6. It is an inevitable product of social development. With the development of society, the aging of the population has become increasingly prominent. The only child has become the main labor force in the society, and the number of people engaged in agricultural production has become less and less. With the continuous improvement of the land transfer mechanism, the one-on-one rural collective production contracting will gradually become a small number of agricultural machinery large households contracting management, factory, specialization, intensive cultivation, large-scale mechanized rice transplanting will become inevitable for rice production, once again Promote the revolution in rice cultivation methods.
