茶苗根结线虫病是国内外茶树种植区苗床茶苗毁灭性病害。本文主要探索利用氨水防治茶苗根结线虫病的可能性。试验表明,防治效果与施药(氨水)穴距和施剂量有密切的关系,穴距10×10cm、剂量20ml 的防治效果可达62.6—92.5%,对照区只有12.1 Tea root-knot nematode disease is a devastating disease of seedling tea seedlings in tea growing areas at home and abroad. This article mainly explores the possibility of using ammonia water to prevent and cure the root-knot nematode disease in tea plants. The results showed that the control effect was closely related to the hole distance and the dosage of pesticide (ammonia), the control effect of hole distance 10 × 10cm and dose 20ml could reach 62.6-92.5%, and the control area only 12.1
