"the highest yield per mu was 1,289.67 kilograms, 127 kilograms higher than the previous record for spring corn yield per mu. this is another new record for spring corn yield per mu in beijing!"
in summer, we rush to harvest wheat, and in autumn, we harvest corn. as autumn deepens, the city's main autumn food crop, spring corn, begins to be harvested. in recent days, an expert group composed of experts from the corn expert guidance group of the ministry of agriculture and rural affairs, china agricultural university and other institutions has conducted yield measurement on corn in the suburbs of beijing. good news came from the beijing spring corn high-yield research field in dawangzhuang village, kangzhuang town, yanqing district. the head of the expert group, researcher xie chuanxiao of the corn expert guidance group of the ministry of agriculture and rural affairs, excitedly announced the results.
as the "landlord" of a high-yield field, sun huiming was even more delighted. "to be honest, i didn't expect to achieve such a high yield this year. it was beyond my expectation." sun huiming has not yet recovered from his surprise.
speaking of the reasons for the high yield, lan hongliang, a senior agronomist at the beijing agricultural technology extension station, said with a smile that behind the new record is the support of scientific and technological forces - the introduction of excellent varieties, advanced technologies and intelligent equipment, and the full-process technical guidance of corn "bigwigs" from scientific research institutions such as china agricultural university and the chinese academy of agricultural sciences.
lan hongliang introduced that the 100 mu corn field in front of him is a high-yield research field implemented by beijing, which was jointly built by beijing agricultural technology extension station and the crop research institute of the chinese academy of agricultural sciences, the national agricultural intelligent equipment engineering technology research center and other units. "the research field selected 9 high-yield new varieties such as c3288 and beijing agricultural science 737, and adopted a number of key technologies such as fine land preparation, precision sowing, water and fertilizer integration, integrated prevention and control of pests and diseases, chemical control and prevention of lodging, and one spray to promote multiple growth. the average planting density per mu is more than 6,500 plants." the planting density of ordinary corn fields is generally around 4,000 plants.
the substantial increase in planting density means that sowing and field management are more difficult, and refined management must be implemented. in this high-yield research field, new agricultural technologies such as beidou navigation air-suction seeders, plant protection drones, field intelligent monitoring equipment, and intelligent water and fertilizer control platforms have been applied to greatly improve the planting efficiency per acre of land. with these multiple supports, there is a new breakthrough in corn yield.
"not only the demonstration fields, but also the yield of grain crops in the suburbs of beijing has been rising year after year in recent years." wang tiantian, deputy director of the planting management office of the beijing municipal bureau of agriculture and rural affairs, introduced that this year beijing implemented a large-scale grain yield improvement action in the city, established 15 high-yield and high-efficiency demonstration areas in the main grain-producing areas in the suburbs of beijing, and built a thousand-acre "two highs and one smart" demonstration area in tongzhou and shunyi districts, promoting large-scale grain yield improvement and balanced production increase from point to surface. at the same time, 38 leading varieties and 25 key technologies were released for each crop, and technical personnel were organized to go down to the front line to carry out fixed-point technical services in the area, so that experts can directly enter households, technology can directly reach people, and good methods can directly reach fields, improve the rate of key links. technology in place and coverage, do everything possible to transform scientific and technological potential into actual output, expert output into farmer output, and typical output into field output.
"according to preliminary forecasts, this year's grain yield per unit area will increase significantly compared to last year," said wang tiantian.
