我司苗圃位于武汉市蔡甸区洪北乡,2022 年春季引进了一批丛生紫薇及红梅作容器苗,肥水管理及病虫害防治对容器苗的健康、快速生长起着至关重要的作用,该文从容器苗移栽到我司苗圃开始讨论,重点讨论施肥的种类、数量、时间对苗木生长的影响,发现容器苗在不同季节需要氮磷钾含量.在病虫害防治方面,发现甲维×高氯氟水乳剂和啶虫脒乳油混剂对紫薇上叶甲和食叶性害虫等的危害具有明显的抑制作用.尽可能遵循"预防为主,综合防治"的植物保护方针,以最小的成本,最优的生态效益,实现容器苗的高产出率.
Our nursery is located in Hongbei Township,Caidian District,Wuhan City.A number of tufted crape myrtle and red plum were introduced as container seedlings in the spring of 2022.Fertilizer and water management and pest control play an important role in the health and rapid growth of container seedlings.This paper starts the discussion from container seedlings transplanting to our nurser-y,focusing on the effects of types,quantity and time of fertilization on seedling growth.It is found that container seedlings need nitro-gen,phosphorus and potassium content in different seasons.In the aspect of pest control,it was found that the mixture of methylvitamin and acetamiprid EC could obviously inhibit the damage of leaf beetles and leaf-eating pests of Lagerstroemia indica.Follow the plant protection policy of"prevention first and comprehensive control"as far as possible,and realize the high yield of container seedlings with minimum cost and optimal ecological benefit.
