Abstract
The invention belongs to the technical field of crop planting, particularly relates to a preparation for effectively preventing and controlling sweet potato underground pests, and further discloses a preparation method of the preparation. According to the preparation capable of effectively preventing and controlling the sweet potato underground pests, umbelliferone serves as an effective component, the preparation capable of effectively preventing and controlling the sweet potato underground pests is obtained in the loading mode that umbelliferone is loaded on the surface of fluorite, the prevention and control preparation is applied into planting soil before sweet potatoes are sown, and by means of the inhibition effect of umbelliferone on grubs, the sweet potato underground pests can be effectively prevented and controlled. Underground pests in sweet potato planting are effectively prevented and controlled, and the yield and quality of sweet potatoes are effectively guaranteed. According to the preparation capable of effectively preventing and controlling the sweet potato underground pests, umbelliferone is used for preventing and controlling grub pests for the first time, and safe and efficient planting of sweet potatoes can be effectively guaranteed.
Description
technical field [0001] The invention belongs to the technical field of crop planting, in particular to a preparation for effectively preventing and controlling sweet potato underground pests, and further discloses a preparation method thereof. Background technique [0002] Sweet potato is an important crop product in my country. It has the advantages of super high yield and wide adaptability. As the bottom line crop of national food security and the energy crop with the greatest potential, sweet potato has been widely valued. my country is the world's largest producer of sweet potatoes. The moderate development of the sweet potato industry is in line with the central policy of storing grain on the ground, storing grain on technology, and agricultural transformation and upgrading, and is also conducive to ensuring national food security. As a pioneer crop of health food, sweet potato is the best food recommended by the World Health Organization, and fresh sweet potato is more...
