Earth!A feast from agricultural science from the field

Cutting straw, bud rice, and picking corn skin. If these lives are hand -made, it is enough to live until the early winter. Today, this tedious program can be resolved through new varieties of corn.

During the 29th China Yangling Agricultural High -tech Achievement Expo (referred to as the Agricultural High School) held in Shaanxi Yang Ling, at the exhibition of Yang Ling Corn Test Base of the Northwest Agriculture and Forestry University of Agriculture and Forestry Science and Technology, which was established for the first time, the precocious and mighty machine collection of corn varieties Many kinds of fields were "old -fashioned".

Zhang Xinghua, an associate researcher of the demonstration base of Yang Ling Corn Test Demonstration Base of the University of Agriculture and Forestry, introduced that the process of planting precocious and densely suitable for machine collection is a process that corn changes from traditional planting to modern planting models. To solve the problem of planting land.

Corn is the main food crop in my country, but its harvest work is a heavy physical labor for the majority of corn growers in my country. It can be seen that the selection of high -quality machines is imperative, and the timing of the variety update has arrived.

The joint harvester shuttled around the field, and the corn straw was spit out behind the machine, and the corn kernels were stored in the cabin. After a few back and forth, the harvester parked the corn kernels on the ground ... Taking the new corn variety Shaanxi Shan 650 as an example, in the past two years, in Shaanxi and Huanghuai area, the variety has been promoted in a large area.

The 650 variety of Shaanxi Shan is a new corn variety cultivated by Xue Jiquan's technical team of Northwest Agricultural and Forestry University of Agriculture and Forestry. In 2018, it passed the review of Shaanxi Province Xiawan District, passed the approval of the Spring and Summer Broadcasting Machinery Group in Shaanxi Province in 2019, passed the National Huanghuaihai Machinery Classification Group for approval in 2020, and the National Nice Breed on the Northwest Machinery Reception Group Test.

It is understood that from 2017 to 2019, the University of Northwest Agricultural and Forestry Science and Technology established the 650 corn varieties and supporting technology demonstration fields in different areas of Shaanxi. After the Agricultural and Rural Ministry, the national corn industry technology system, the national corn cultivation school group, etc. Pucheng, Xunyi, Yulin, and Dingbian Machinery on -site actual production acceptance, the highest per mu is 1122.3 kg, has the characteristics of the "three lows" with low grain moisture content, low field inversion rate, and low seed damage rate. The record of more than 750 kg and more than 1,100 kg of irrigation corn. From 2019 to 2020, the Chipai General Field of the Chinese Academy of Agricultural Sciences established a high semi -demonstration field, with a measured yield of 1465.25 kg.

From September 15th to 19th, the 29th Agricultural High School will be held in Yangling, Shaanxi. This session of the Agricultural High School will set up field exhibitions for the first time.

The field exhibition mainly focuses on the breeding of good breed, water -saving irrigation, soil improvement, smart agriculture, facility agriculture and other aspects. Through holding display observation and tasting experience, Yang Ling's high -tech integration of Yangling Agricultural High -tech integration in the development, promotion, and testing of the characteristics of modern agricultural industries and experiments in characteristic modern agricultural industry New results achieved by demonstration; comprehensively displaying the positive contributions of the new varieties of modern seed industry in ensuring food security; comprehensively demonstrating the important achievements of technology to lead the country's revitalization to promote industrial development. Fully demonstrate Yang Ling's implementation of the national mission, demonstrate the mission of driving the development of modern agriculture in the dry area, and effectively put the level of the agricultural high -ranking field exhibition, the characteristics, and the influence.

"The first -time agricultural high -ranking field exhibition established this year is very distinctive. Compared with the samples placed in the exhibition hall, the field exhibition is more three -dimensional and intuitive. Exhibitors can experience the growth and characteristics of the variety in their realm." Zhang Xinghua said, hoping to use this session of this year The new varieties of corn displayed in the fields set the "Shaanxi Model" for the mechanized production of corn in my country.
