The average yield of wheat is 823.2 kg!Qingdao's "ultra -ton and a half grain" high yield demonstration Tianchuang History's highest record

Qingdao Daily/Guanhai News, June 20th. Recently, the expert group of the Agricultural and Rural Affairs Department of Shandong Province organized a realistic demonstration field in the "Super C -ton Half Grain" high -yield demonstration field located in the Qingnong Seed Seed Professional Cooperative in Pingdu. For production, the average yield of wheat per mu is as high as 823.2 kg, which is the highest record of Qingdao wheat alone.

This is the fourth year of wheat alone in our city that has exceeded the 800 kg mark since 2018. The innovative and integrated technical model is further mature, becoming a replicable and promoting main promotion technology, which is of great significance to further improve the city's comprehensive production capacity of the city. The specific practice of Qingdao, which is a national strategy of "Tibetan Grain", reflects that the scientific and technological level of food production in our city has reached the leading position in China.

At the production site, expert groups consisting of experts from Shandong Agricultural Technology Center, Qingdao Agricultural University, Qingdao Agricultural and Rural Bureau and other units, in accordance with the "National Grain Creation of Grain Extraordinary Creations (Trial)" and "Shandong Province's Grain and Oil High Production Creation and Testing Test The requirements of the Examination and Acceptance Measures, the growth of wheat fields was checked on the spot, and the acceptance opinions were formed through measurement, mechanical harvesting, weighing, moisture measurement, and impurities. The total area of ​​demonstration fields is 120 acres, and the real income area is 3.9 acres. The actual average production of the demonstration field is 823.2 kg.

The high-yield demonstration field of wheat-corn "over-tonnage and half grains" has set the highest record in Qingdao, and the results are not easy. This is a successful demonstration of agricultural scientific and technological personnel in the city and planting households to cooperate with planters to turn the output of experts into grain farmers. To achieve the high yield of wheat, we must fully tap the potential for yield for production, and do everything possible to increase the number of ears, ears and thousands of grains, and thousands of grains, so as to achieve "hiding food in the ground, hiding grain in technology".

The wheat varieties planted by demonstration fields are Qingnong No. 7, which is a new high -yield variety selected by Qingfeng Seeds Co., Ltd. in our city. It was approved by Shandong Province in 2019. This variety is suitable, good resistance, strong disease resistance, high disease resistance, high weight of thousands of grains, and large output potential. It reviewed the super high yield of 812.7 kg per mu in that year, and it is suitable for the use of high -production blocks in the province. Through this year's high yield demonstration, the characteristics of Qingnong No. 7 resistance and disease resistance have been well displayed, especially the variety advantages with large grain volume and high post -grouting strength have been fully verified. The ideal variety of high yield and high yield.

Wheat creation is high, not only to have good varieties, but also to support good technology. Looking back at the development of wheat production technology in our city, each output breakthrough is inseparable from the strong support of new agricultural technology. In the 1990s, under the support of wheat pseudo -cultivation technology, the highest production of wheat in our city across 650 kg in 1999 (653 kilograms of Yulan Town in 1999); Daguan (726.1 kg of Zhangjiaqiu Village, Benglian Town in 2008), wheat nitrogen fertilizer's backward technology played a key role; in 2015, through the innovative development of wheat wide pseudo -technology technology, it successfully passed the 750 kg mark and created a number of yields 786.6.6.6 Kg -out high yield record (786.6 kg of Zhangjiaqiu Village, Nanzhang Town in 2015). At present, the core technology that breaks through the 800 kg of yield is an innovative technology model based on the whole process of drip irrigation and fertilizer.

This technology is a major technical achievement achieved by the city's agricultural technology promotion departments and colleges and universities such as Qingdao Agricultural University. Waiting for the bottleneck problem, the traditional planting method of drip irrigation technology is the core planting method, integrating water and fertilizer, composting fields, deep cultivation of deep pine, wide phenomenon, winter and spring suppression, nitrogen fertilizer back, one spray and three defense, etc. The green and high -efficiency new technology model has the characteristics of more than 30%of water saving, more than 20%of fertilizer, more than 10%of the land, more than 2 or more, and the efficiency of about 200 yuan per mu. At present, 4 local standards of Qingdao City have been formed, and 2 local standards in Shandong Province have been formed, and the national industry standards are formulated.

In order to continue to improve food production capacity, the organizational technical forces of the agricultural and rural departments of Qingdao City insist on writing the paper on the earth, implementing it in farmland, and the construction of new agricultural technology innovation and integrated demonstration bases in the city. The professional cooperatives of Pingdu Lanqingnong Gongnong Seeds of Pingdu Lanqing, which are realized, are typical representatives. In response to the production of food this year, the city's agricultural technology department actively integrates and promotes the promotion of "excellent varieties+seed coats+composting field+mechanical suppression+drip irrigation fertilizer regulation+grass pests green prevention and control+green prevention and control+green prevention and control of pests+grass pests. "Green high -quality and efficient technical model. In particular, in response to unfavorable factors such as the evening flood broadcast and drought in spring, special operations such as "technology strong seedlings" and "winning a hundred days of tackling" and other special operations were carried out. The stability of the area, the production, and the overall production have remained at a high level in recent years, and made outstanding contributions to protecting the "big country of the country" to protect the safety of food security.
