China's rice transplanting new technology will be promoted next year
1. Turn off the hydraulic system: Before replacing the hydraulic cylinder, it is necessary to turn off the system to avoid liquid leakage in the hydraulic system.
2. Disassembling the hydraulic cylinder: Disassembling the hydraulic cylinder requires the use of tools such as wrenches, screwdrivers, etc. Firstly, the hydraulic pipeline needs to be removed, and then the bolts of the hydraulic cylinder need to be removed to remove the hydraulic cylinder from the machine.
3. Check the hydraulic cylinder: Check if there is any damage to the hydraulic cylinder, and if there is any damage, replace it.
4. Install a new hydraulic cylinder: Install the new hydraulic cylinder onto the machine and secure the cylinder with bolts.
5. Connect hydraulic pipeline: Connect the hydraulic pipeline to the hydraulic cylinder, pay attention to the position and direction of the connection, and ensure that the connection is secure.
6. Test system: after replacing the hydraulic cylinder, it is necessary to test whether the system operates normally, check whether the hydraulic cylinder operates normally, and deal with any problem in time.
7. Cleaning work: Clean the liquid and debris in the hydraulic system to ensure that the system is clean and avoid any impact on the system.
[China Agricultural Machinery Industry News] It is understood that mechanical transplanting can complete the planting operation of 1 to 3 acres per hour, which is 5-8 times of manual transplanting, high efficiency and high speed. From the perspective of farmers' labor costs, mechanical transplanting It costs 50 yuan per mu, while the traditional manual transplanting costs 150 yuan, which greatly reduces the cost of transplanting. Reduce the labor force by 1-2 workers per mu. Not only let everyone get rid of the heavy physical labor, but also achieve the purpose of saving labor and time.
Liuyang's rice transplanting area in 2016 is expected to reach 300,000 mu
This year, the area of ​​rice transplanting in Liuyang is expected to reach 300,000 mu. In order to exchange and introduce the experience of rice transplanting, and accelerate the mechanization of rice production, the live demonstration of the 2016 rice plant transplanting in the city was held in Guankou Street and Tiancun.
At the scene, advanced tools such as high-speed rice transplanters, self-propelled high-bar spray fight drugs, and professional pesticide sprayed plant protection drones produced by five agricultural machinery manufacturers inside and outside the province were demonstrated in turn, attracting many villagers to watch. Qiu Jixin, who is driving a high-speed rice transplanter, said, “This year I transferred 580 acres of land. With this machine, it takes only ten days to complete the transplanting task.†In addition to reducing labor intensity, high-speed machine transplanting has a quick return. Features.
Since the promotion of rice mechanization transplanting technology in 2007, by the end of 2015, Liuyang City has owned 428 transplanting machines, and the rice transplanting area of ​​the city reached 250,000 mu, accounting for 22% of the total rice production area of ​​the city, effectively boosting rice. Industrial Development.
The mechanized rice transplanting technology has high planting efficiency, good quality of transplanting, and replaces labor with machinery, which reduces labor intensity and plays an important role in increasing rice production efficiency, high yield and stable yield, and increasing farmers' income. It broke the bottleneck of mechanization of rice, improved labor productivity, reduced labor intensity and saved labor resources. Rice machine insertion technology has the advantages of high planting efficiency and reduced labor intensity, which can achieve rice production efficiency, high yield and stable yield, and increase farmers' income. At the same time, compared with artificial transplanting, rice seeding technology is relatively late in seedling cultivation, and the seedling volume is uniform. At the same time, if it is combined with rice insect-repellent nets, the occurrence of rice pests and diseases can be greatly reduced.
Machine insert new technology will once again increase the output of machine transplant
At the beginning of 2016, at the rice plaque-like seedling cultivation and machine insertion technology exhibition held in Hangzhou, the new technology of the machine attracted the audience's attention. It is understood that this technology can increase the output of machine insertion on the basis of machine insertion and production increase.
In recent years, the application of rice transplanting technology in China has developed rapidly. The existing rice transplanting technology is mainly introduced from Japan and South Korea. However, China's rice season and variety types are very different from Japan and South Korea, especially in China. About 55% of the planting area, agronomy requires the precision seeding of hybrid rice, evenly thinning, which puts forward new requirements for the transplanting technique of hybrid rice production area. Solving the problem of rice transplanting in hybrid rice is the key to developing rice transplanting in China.
The rice research and seedling transplanting technology developed by the China National Rice Research Institute combines the advantages of scorpion seedlings and blanket seedlings to achieve low-bundle-forming blankets and quantitative seeding. After the machine is inserted, the seedlings have a greening effect. Fast, early fast-acting characteristics, can better play the potential of hybrid rice production. The reporter learned from the China National Rice Research Institute that the technology has been promoted in single-season hybrid rice, continuous cropping early rice and late rice in more than 10 demonstration sites in Zhejiang Fuyang, Jiaxing Pinghu, Ningbo Yuyao, Wenzhou Rui'an and Taizhou Xianju. The effect is better.
At present, China's rice machine insertion uses carpet-like seedlings, while the scorpion-shaped seedlings are mainly used in throwing sputum, which has the advantages of less transplanting, less seedlings, quicker greening, etc., but it cannot be applied on rice transplanters. The 秧-shaped blanket seedling machine transplanting technology is mainly used to solve the problems existing in the current hybrid rice transplanting machine. The special 钵-shaped blanket-shaped enamel disc developed by the research and development is used to grow the upper scorpion-shaped scorpion shape seedling, which has both scorpion seedlings and blanket seedlings. The features and advantages of the rice machine are easy to insert.
Researcher Zhu Defeng, a rice planting expert at the China National Rice Research Institute, said that the technology can be used in hybrid rice machine insertion, which can save 25-30 yuan per hybrid seed and achieve high yield and stable yield. In the demonstration of early rice transplanting, the technology can produce up to 500 kg per mu, which is more than 10% higher than that of the general machine. At the same time, the technology can also be applied to continuous cropping of late rice, which solves the problems of late rice transplanting due to long age, resulting in high plant height and difficult machine insertion. In the next step, the China Rice Research Institute will expand the scope of its demonstration. This technology will be demonstrated and promoted in Heilongjiang and Hubei next year.
