The fundamental way for agriculture lies in mechanization. Looking at today's agricultural planting methods, there has been a tremendous change compared with the past. From mechanization to mass planting and mechanization in the past, from the sub-fields to the present, play a decisive leading role. The level is also increasing year by year, in the past 98% of the traditional manual methods have been replaced by machinery.
It is true that the development of agricultural machinery in China has made leaps and bounds in recent years. However, there are only a few advanced agricultural machines with creative Chinese characteristics, most of which are based on imitation. This does not mean that Chinese people's minds do not possess innovative genes , But the traditional concept led to the development of China's agricultural machinery can no longer be a new level.
Agricultural machinery industry development on the road constraints
Some large-scale agricultural machinery companies are unilaterally pursuing output value. In terms of product research and development, there are only a few truly representative agricultural machinery. Although small-scale agricultural machinery enterprises lack the funds for project development, they may face bankruptcy once the R & D fails. Small-scale privately-owned enterprises Enterprises lack of funds and good management, can not win the country's scientific research funds ... ... These problems are cross-border innovation and development in China's agricultural road 'stumbling block', resulting in truly independent intellectual property rights of advanced agricultural research and development has no substantive results .
In this aspect of rice seedling cultivation, even the advanced agriculture in developed countries, there is no real breakthrough in this problem. Rice transplanting is a late start of an agricultural planting mode, since the promotion, so far more than a decade, rice Transplanting machine with obvious advantages have been recognized by the market, accepted by the majority of farmers.Transplanting rice seedling planting link is a crucial part of the current market there are two main modes of nursery:
Full artificial seedling mode
The whole artificial seedling breeding model is the most traditional mode of operation in the past. Through a large number of artificial transplanting seedlings one by one in the field, a certain amount of subsoil is then spread on each seedling tray, And then artificial sowing, and finally in the tray covered with overburden artificial sowing the biggest drawback is that the seeds, subsoil, soil uniformity is not accurate control, relying on experience to complete the process is too cumbersome, humpback work mode of work Half-day people back pain .Now the rural labor generally into the aging .This low efficiency, labor-intensive mode of operation has basically been eliminated.
Semi-automatic assembly line
Semi-automatic line of seedling planting model was first introduced from Japan to Japan, through the mechanical completion of subsoil, sowing, soil cover and other basic procedures. Transplanting seedlings through the transport mode, the tray will be placed on a tray seedlings, seedling line only The use of hard plastic seedling tray, the cost is about 6-10 times the ordinary soft seedling tray, a one-time investment costs are larger .To farmers is a big burden.Second is the need for manual tray by a plate by seedlings The pool is transported to the field and then placed on the seedbed one by one, which is not easy to transport due to the narrow potholes in the road during transportation, and the labor cost is also very high.
Self-propelled track-type transplanter
In response to the above shortcomings, after five years of Jiangsu Yongtao, eventually in the rice seedling mechanization has made a breakthrough, developed 2BPZ-4A rice seedling nursery planter. The design concept of this machine from farmers in Northeast China, by Jiangsu Yongtao introduced a new type of seedling raising machine which was introduced by Yangzhou University for several times and improved.They won the third prize of scientific and technological progress of Taizhou in 2016 and the provincial high and new technology product in 2016. At present, Items, utility model patents 6, design patents 2. This machine combines the advantages of both manual mode and semi-automatic assembly line, largely to solve the shortcomings of the two methods of raising seedlings, can be completed at one time subsoil, sowing , Soil cover, tray output, the final automatic neat laying of seedlings in the seedbed, and can directly use the floppy disk, you can directly control the thickness of subsoil, sowing volume can be adjusted, cover soil adjustable, and finally lay the seedling tray directly in the seedbed. Only three people can operate (two wobbled, one person to add soil) to save a lot of labor, work efficiency is 60 times more artificial.
During the demonstration, the product felt the peasants' trust and expectation on the automatic seedling raising machinery.The successful development of this machine has filled the gaps in the international and domestic markets for its reliability and practicability, reduced the labor intensity of peasants and reduced Labor costs and material costs, operating efficiency has been significantly improved.Traditional seedling raising mode has been a major breakthrough in the mechanization of seedling raising this problem has been fundamentally resolved.
