水稻潜根线虫广泛分布世界各水稻产区。在我国水稻产区也普遍发生,但此病尚未引起人们的注意和重视。据国外报导,由于此而引起的水稻减产为10—30％。世界很多国家对线虫发生记载为:潜根线虫适宜在潮湿的稻田生长,干燥或排水良好的土壤对其生长、繁殖和存活,都有不利。因此,犁冬田、晒冬田和旱作或水旱轮作等措施都可减少线虫的数量,达到防病的目的。
Rice rootstock nematodes widely distributed in the world’s rice producing areas. Rice production areas are also common in our country, but the disease has not attracted much attention and attention. According to foreign reports, as a result of rice yield reduction of 10-30%. In many countries of the world, the occurrence of nematodes is described as that the potential root-knot nematodes are suitable for growing in moist paddy fields, and the dry and well-drained soils are disadvantageous in their growth, reproduction and survival. Therefore, plowing in winter fields, sun-drying fields and rotation or drought and drought and other measures can reduce the number of nematodes, to achieve the purpose of disease prevention.
