When it is warm and cold, it will be a green spring. It will also be a new cycle of the earth's recovery and blooming of flowers. Everything's growth depends on spring to get nutrition. As the saying goes, "A year's plan lies in spring." This is the truth. Although spring is not the harvest season, it determines the final harvest. In order to help users manage fields scientifically and distribute crop nutrients reasonably in this cultivation season, and finally achieve high quality and high yield, our company held a gold partner "Crazy Control + Yogurt" market start-up meeting in Gongan County on March 12, 2018, which also indicates that the company started a new journey with the baton of "serving agriculture and repaying society".
