Northwest flour ridge wheat increases by 30% per mu.

Original title: northwest flour ridge wheat has increased production.

On-site yield test and acceptance of the project "demonstration of High efficiency cultivation of Wheat Powder Ridge in Fuping County, Shaanxi Province"

In the northwest region of the summer harvest season, wheat waves are surging and farmers are enjoying harvesting wheat. On June 5, under the organization of Guangxi Academy of Agricultural Sciences, experts from the Chinese Academy of Sciences, Northwest Science and Technology University of Agriculture and Forestry, Gansu Academy of Agricultural Sciences, Shaanxi Weinan Agricultural Bureau and other units carried out by Guangxi Wufeng Machinery Co., Ltd. and Guangxi Academy of Agricultural Sciences cash crop research institute and other units of the "Shaanxi Fuping County wheat flour ridge high efficiency cultivation demonstration" project was tested and accepted on the spot.

The results of yield measurement show that Caocun Town, Fuping County, Shaanxi Province, in the northwest region, used powder ridge agricultural technology to grow wheat for the first time, with a yield of 527.26 kg per mu, an increase of 121.37 kg per mu or 29.9% more than that of traditional farming managed under the same conditions in the same piece of land.

According to reports, the project used self-propelled powder ridge machinery developed by Guangxi Wufeng Machinery Co., Ltd. in October 2015 to carry out powder ridge tillage of about 35 cm, while the control was traditional rotary tillage, with a tillage depth of about 18 cm. It was sown on October 20 of that year, and the powder ridge was consistent with the control's fertilization level and field management measures, and were managed according to the local production level.

"the machine is absolutely good. There is no need to level the ground after passing, and the machine does not press the ground." Standing in his soon-to-be-harvested wheat field, Zhai Xinshe, a villager from Daqu Village, Caocun Town, Fuping County, told the China Science Daily reporter about the scene before planting, and what made him more happy was that the growth of wheat after the flour ridge was "getting more and more beautiful."

A reporter from the "China Science News" saw at the scene that when planting wheat in powder ridges, the plants are strong and the growth is strong, and they also show green branches and wax stalks at harvest, and their appearance is obviously superior to that of conventional planting; from the soil profile, the loose soil layer of wheat planted in powder ridges is still maintained at 20 cm, while that of conventionally planted soil is only 13 cm, and the roots of wheat planted in powder ridges are well developed and have a certain number of white roots, indicating that they are strong in vitality.

"Fuping County has achieved high yield by planting wheat with powder ridges, which once again proves that powder ridge agricultural technology can make the land deeply ploughed and loosened, conserve water and fertilizer, and is an effective way to increase crop production, farmers' income and ecological gain." Song Songquan, head of the acceptance expert group and a researcher at the Institute of Botany of the Chinese Academy of Sciences, said that this new farming technology, which can increase production and income without additional investment, is a major invention and a new technology needed by this dry and rainless land in Shaanxi Province. it allows natural precipitation to be stored in loose soil, allowing a drop of water to produce more food.

When discussing the opinions of field acceptance, experts such as Zhang Baojun, professor of the School of Agriculture of Northwest Agriculture and Forestry University, Lu Peng, chief agronomist of Weinan Agricultural Bureau, spoke highly of the powder ridge technology, thinking that powder ridge can activate soil and improve its water retention performance. improve the population quality of wheat, increase the number of effective spike and root population per mu and increase the biological yield. The growth of powder ridge wheat is strong enough, the senescence is delayed and the filling period is prolonged. These factors are the key to greatly increase the per unit yield of wheat planted in powder ridge.

"for the northwest, water is particularly important for the growth of crops." After the yield measurement, the party visited Shanlun, an academician of the Chinese Academy of Engineering and a leader in the field of dryland agriculture in China. He said that the quality of a technology is judged by its current effect of increasing production and whether it is sustainable.

The application of powder ridge agricultural technology in wheat has obvious effect on increasing yield. Prior to this, the Institute of Agricultural Resources and regionalization of the Chinese Academy of Agricultural Sciences established a continuous experiment on powder ridge cultivation in Qianli Village, Caowa Township, Wuqiao County, Hebei Province. In 2011, the depth of powder ridge was 30 cm, and the mu of wheat in the second crop increased by 128.32 kg, or 34.2%. In the fourth year, the planting of wheat still increased by 141.59 kg per mu, an increase of 32.57%. In 2013, Henan Academy of Agricultural Sciences planted wheat in Wenxian County with a powder ridge (depth more than 30 cm). The average yield per mu was 565.71 kg, an increase of 131kg or 30.13% over the control mu.

At the production test and acceptance site, Wei Benhui, the main inventor of powder ridge agricultural technology and a researcher of Guangxi Academy of Agricultural Sciences, told China Science Daily that powder ridge agriculture and its technical system is a return to nature. it can increase production, improve quality and conserve water without increasing the application amount of chemical fertilizers and pesticides, irrigation water consumption and artificial input. In the past 8 years, it has the advantages of deep ploughing and deep loosening without messing up the soil layer, preserving water, increasing oxygen, increasing temperature and light salt, being free from regional restrictions, and conducive to stable crop production. It has been applied and verified in 20 provinces and more than 20 kinds of crops in China. "Powder ridge agriculture and its technical theory system can solve the problem for the current Chinese agriculture." Wei Benhui said. (our reporter Qin Zhiwei)
