Corn grain harvest should cross two gap

Recently, in Jinan City, Shandong Province, Zhangqiu District Zao Yuan Wo Cheng agricultural cooperatives of the corn base, held by the Shandong Provincial Agricultural Machinery Research Institute led the whole process of Huang-Huaihai corn mechanized technology demonstration and seminar. Experts believe that crack the Huang-Huai-Hai region corn grain harvest problems, speed up the development of special machinery is on the one hand, breeding fast dehydration, lodging professional varieties is another aspect.

 

“Corn water content is generally about 35%, so the grain harvesting effect is not good, grain damage rate is higher.To solve the Huang-Huaihai region corn grain harvesting problems, to speed up the development of special machinery is on the one hand, breeding fast dehydration, lodging resistance Professional varieties are another aspect. “Chinese Academy of Agricultural Sciences researcher Li Congfeng said.

 

“Because of the slow dehydration of corn, but also grab the agricultural planting wheat, it is difficult to directly harvest corn kernels, which is plagued by the Huang-Huai-Hai area corn one of the biggest problems.If you can directly harvest the grain, picking, peeling, threshing, Straw crushed into the field and other processes can be completed at one time, will be able to greatly reduce the labor intensity of farmers, and now generally used or harvest spike, need to dry two or three days before the bar to threshing, threshing but also drying, not only time-consuming Workers, it is difficult to find the drying site. “Zhangqiu City Agricultural Bureau Secretary Ming Huaiqiang said.

 

Direct harvest corn corn benefits, how to promote the situation? Shandong Province Agricultural Machinery Party Committee Secretary, chairman Fan Benrong frankly: “in the Huang-Huaihai summer corn producing areas to promote corn grain harvest is also facing real difficulties.One corn and wheat rotation, farming and other people, farmers grow corn is difficult to do 110 Day harvest grain requirements, the majority is about 100 days to close; the second is a special grain harvest varieties research and development still have to break through, the mechanical harvest grain moisture content below 25%, and the current harvest is generally more than 30%. Generally high water content, mechanical harvesting grain damage rate is relatively high.
