橡胶小苗采用露地覆膜栽培,会引起胶苗“日烧病”,死亡率达50.3％。应用地膜覆盖栽培结合盖草培肥方法,可提高胶园盖草培肥效果,明显地改善表土的物理性状和有效养分供应,使橡胶幼树茎围生长量增加8.1～23％,开割树增产干胶5～14.1％;地膜覆盖栽培还能提高胶园土壤管理效率,增加经济效益。
Rubber seedlings planted open-field cultivation, will cause the vaccine “Japan burn disease”, the mortality rate of 50.3%. Application of plastic film mulching cultivation combined with cover grass and fertilizing methods can improve the plasticity effect of plastic grass cover grass, significantly improve the physical properties of topsoil and effective nutrient supply, so that young stem growth of rubber trees increased by 8.1 to 23%, open cut tree 5 to 14.1% increase dry glue; Mulch Mulch can also improve the rubber plantation soil management efficiency and increase economic benefits.
