On 4 december, a critical period of field management was ushered in in the potato fields of the town of poo, in the kamongi district of kamong city. The sights are full of potatoes, the leaves of green oil are covered in fields, showing a happy picture of the harvest。
The potatoes are growing well in the town of treasure。
The town is growing 20,000 acres of potatoes, and this autumn the machine planted 20 per cent of the area, mainly for large fields. On the edge of the field, peng chang ming, the head of the antex agricultural machine professional co-operative in the go well district, is walking back and forth to check on the potatoes. “at the end of september, we used the potato sowing machine developed by the shireiga team at sichuan agricultural university to save $500 per acre in human cost, which farmers felt was working well in the hope that next year the machine would be adapted to small fields.”
The potato sowing machine developed by kawano is being planted in the town of poe。
The town is just a microcosm of the many science and technology demonstration bases of sichuan agricultural university (hereinafter referred to as “kawanoda”). This year, the school's scientists have continued to pursue a combination of productive research and agricultural education, particularly through the innovative application of the “good breed + smart farm machine”, which has provided solid scientific support to ensure a steady increase in the production of the “standard house”。
Good breeding practices guarantee a steady increase in production
In yongfeng village, in the eastern slopes of maeyama city, a large 1,500-acre rice pilot demonstration base is now growing chinese medicine and vegetables and will be harvested next spring. A month ago, the village rice harvest almost ended, and data from the survey of rice by the team of prof. Mahuo, director of physiological ecology and cultivation in sichuan province, showed a steady rise this year, with average acre production expected to reach 800 kg per acre, compared to 770 kg last year。
This summer, a team of professor madu, stationed in yongfung village, observed rice growth in the fields。
The hard-won increase, high-temperature, drought from august to mid-september, adversely affected rice growth. Ma told journalists that while rice varieties that had benefited from team selection were highly resistant to heat and drought, team technical services were in place to guide farmers in scientific water management and accurate and efficient fertilization. “a good seed will have to be cultivated, and the best varieties and techniques will have to be mastered in order for farmers to be able to carry out its value.” as a result, mahu and the team insisted on regular visits to the fields to check on the growth of rice, to explore the production challenges, to train directly on the fields, to talk about technology and to teach growers. Not only did they reap the fruits of the harvest, but more than 3 million acres in more than 20 counties such as hojiang, dan-lin, han-jin, sai-chung and rong county, and the other rice bases served by the mahu team had done well。
Corn is also an important part of autumn grain. This year, the three main push varieties of kawanoun accounted for at least 10 per cent of the total maize area in the south-west, with good outreach. "this year the southwest rains more abundant and the corn is a harvest!" professor lanhai, secretary-general of the grand maize institute of kawaran, is pleased to say that he is a member of the party. His team had used genome-wide selection techniques to construct a new hybrid model for the south-west maize region, the results of which had recently been published. Together with the technology option and the daejeon experiment, they have successfully selected a range of new varieties, one of which is the breakthrough “edi 899”. This year, 200-acre series of demonstration acres produced an average of 820. 6 kg。
“the achievement of a steady high productivity also depends on the implementation of care technology.” prof. Yang weng, the head of the technical team for the complex cultivation of the large-beans corn belt in kawano, directed the team in advance to develop a systematic design based on production objectives, from seeding to later management, and to implement soybean monolithic promotion requirements throughout the entire growth cycle, effectively ensuring maximum yield growth under existing conditions. It is known that, under the adverse effects of the current year's floods and drought, the complex soybeans growing in the inshou district and in the safe areas have achieved a “reverse upturn” harvest。
Smart farm machines to improve productivity
More than a month ago at the fall harvest, the corn, soybean harvesters and soybeans, etc., developed by the river farmers became a beautiful landscape in the hills. Not only have these smart farm machines significantly improved harvest efficiency, they have also reduced the labour intensity of growers and made autumn harvests easier and more efficient。
This year, the kawasa institute of mechanical and electrical sciences was involved in the “attendance of heaven” vulnerable crossing project, which was responsible for the development of efficient corn harvesters and the development of efficient maize seed harvesters for use in hill hills. “a harvester can harvest 5-8 acres of corn in an hour, and 40-50 acres in a day can be easily taken.” research and developmentists chen shuan and han dan dan told journalists that in autumn grain production, harvesters aggregate 2,000 acres in china river county, with over 590 kilograms of acre production, with a total loss rate of less than 3 per cent, and are popular with farmers。
The efficient corn seed harvester works in the field。
Back from the field to school, chen zheng and han dantan immediately went into the process of improving the harvester. “to address, on the one hand, the problem of high rates of fragmentation of maize seeds under dense-planted conditions; and, on the other hand, to further optimize core components such as cutting platforms, detached devices and sorting devices.”
Potatoes are the fourth largest food crop in sichuan, but traditional potato seeding machines do not have replanting devices. In response to this deficiency, the team of professor shereika developed, over a year, a saw-tooth supplement system with a “photo-vision + visual test”, adding self-adapted seeding devices, resulting in a drop rate of well below 5 per cent and a rebroadcast rate of less than 1 per cent。
In recent years, the sichuan university of agriculture has invested 100 million yuan a year in a project to provide services to the "sentour silo", in collaboration with chengdu, meishan, dazhou and cool mountain, to create 1 million acres in the core areas, demonstration areas and model fields of the sengdu silo; and tow potatoes and small scientific and technological institutions such as yongfeng rice, to promote new varieties, research and demonstration of new technologies, to introduce or cultivate more than 60 new varieties, to promote more than 80 new technologies and to create more than 2 billion local capacities。
