When interviewed in Hualong Township and Taitou Township, Shouguang City, the reporter saw a lot of vegetable farmers making heavy use of the yam loosening machine at the time of planing the shaanxigou. Why does the yam groat machine be welcomed by vegetable farmers? What are its advantages?
First of all, the use of loose trench planers ensures that the depth of the yam ditch is consistent and that it saves time and labor. When digging yam trenches with yam pods, as long as loosening the sprocket into the ground, the sprocket can be loosened from one end of the furrow to the other end of the furrow. Because of the use of small excavators to dig trenches, there have been different trenches.
Second, it is conducive to the growth of yams. After using the pine channel ditch, the looseness of the soil in the ditch is the same, which is more conducive to the root system under the yam colonization and promotes the growth of the yam root group. At the same time, the yam tuber grows downwards due to external resistance. The chance of bending is reduced. However, the small excavators often used by vegetable farmers in the digging of yam and ditch backfill soil cannot completely smash the soil blocks, resulting in inconsistent soil looseness and easily causing bending of yam tubers. Therefore, the small excavators commonly used for digging yam trenches were gradually replaced by yam sloping trenchers.
