Shijiazhuang, 31 Aug (Zhongxin.com) -- On the morning of 31 August, in a corn field in Kanshang Village, Zhugezhuang Town, Changli County, Qinhuangdao City, Hebei Province, a large self-propelled green storage feed harvester and six transport trucks were engaged in mechanical operations.
With the roar of the machine, corn stalks that are more than one person tall are automatically harvested, crushed and loaded into the car under the rotation of the gears.
Grower Lu Weidong said that this self-propelled green storage feed harvester can harvest one acre of land in two minutes, producing more than three tons of green storage feed, which not only saves labor, but also can turn the remaining straw deep into the soil to achieve straw return, not only improving land utilization, but also avoiding polluting the environment. These green reserves of corn will be transported directly to the pasture, and by packaging and fermenting to become high-quality feed for the cattle and sheep on the pasture, the yield per acre of farmers will be increased.
Wang Haifeng, chairman of changli county Defa agricultural machinery service professional cooperative, said that corn straw green storage feed technology is to chop fresh whole corn straw, use microorganisms for anaerobic fermentation, a technology to make feed under closed conditions, the crude fiber and protein contained in the processed straw is one of the necessities of dairy cows' daily feed, which helps dairy cows grow and produce milk, and unlike the traditional harvest of green storage corn, they use the most advanced international "kneading silk grain crushing technology". It can increase the utilization rate and conversion rate of green storage feed by about 5%.
Wang Haifeng said that since 2018, with the help of Changli County Supply and Marketing Cooperative, the cooperative has invested more than 20 million yuan to purchase more than 30 sets of large-scale agricultural machinery and straw treatment machinery such as green storage harvesters, and on the basis of providing 30,000 mu of land for county farmers to deeply turn over and soil remediation, it has also gone to Shandong, Ningxia, Inner Mongolia and other places to carry out cross-regional green storage harvesting operations, and in 2020, it has completed 370,000 tons of silage operation orders, and the land custody area has reached 130,000 mu.
The reporter learned from the Propaganda Department of the Changli County CPC Committee that in recent years, Changli County has explored and innovated the "Green Storage Feed" agricultural machinery socialization service mechanism with the goal of increasing agricultural efficiency and increasing farmers' income, and created a new agricultural service operation system with Changli characteristics while developing and strengthening various agricultural machinery cooperative service organizations.
At present, under the guidance of the agricultural department of Changli County, the county has set up more than 20 agricultural machinery service cooperative organizations, which can harvest more than 700,000 tons of green storage feed across regions from mid-August to November every year, and recover more than 600,000 tons of corn, rice, wheat and other straw, which has greatly improved the socialization service level of changli agricultural machinery.
