Embodiment Construction

[0012] 1. Strengthen the quarantine of seed potatoes and seedlings. In the comprehensive prevention and control, plant quarantine should be strengthened to protect disease-free areas; disease-free seed reserve bases should be established in diseased areas.

[0013] 2. Select disease-resistant varieties. No immune varieties have been found yet, but there are obvious differences in resistance among varieties. Try not to choose susceptible varieties such as Yanshu 27 and Xushu 18.

[0014] 3. Reasonable crop rotation and stubble rotation. It is forbidden to plant sweet potatoes or potatoes, peanuts, and bean crops within 4 to 5 years of the diseased field, and corn, millet, sorghum, and cotton should be planted instead.

[0015] 4. Eliminate the sick and disabled. Strictly remove diseased potato residues, diseased seedlings, and diseased vines in the three stages of spring seedling raising, summer transplanting, and sweet potato harvesting and storage, and burn or bury them in...

Abstract

A new technology for the prevention and treatment of sweet potato neck nematode disease, which is characterized by strengthening the quarantine of seed potato seedlings, selecting disease-resistant varieties, rational crop rotation, eliminating diseased residues, and chemical control. The phenomenon of neck nematode disease and so on. The per-mu yield of sweet potato has been greatly improved, which is about 40% increase per mu, and it is especially suitable for planting in mountainous areas.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a new technology for the prevention and treatment of sweet potato neck nematode disease. Background technique [0002] Stem nematode disease of sweet potato spreads and spreads quickly. Once the sweet potato is infected with the disease, not only the output will be reduced by 30%-40%, but also the infection area is relatively wide, which greatly reduces the planting area of ​​farmers. At present, the disease has become the main disease of sweet potato cultivation. Contents of the invention [0003] The invention aims to solve the technical problems existing in the traditional sweet potato planting management method, and invents a new technology for the prevention and treatment of sweet potato neck nematode disease. [0004] The present invention is for solving the problems of the technologies described above, the technical scheme that takes, a kind of prevention and treatment new t...
