林业化学除草技术的研究

从1974～1990年,在苗圃、幼林、造林地及防火线上筛选适用的除草剂,结果表明:松、杉苗圃以除草醚、果尔作土壤处理,防效达90％以上,高于1m的松、杉、阔叶树、果树以草甘膦作叶面喷洒,防效达85％以上;造林地以草甘膦、2,4-D丁酯、草甘膦+调节膦及威尔柏+草甘膦作叶面喷洒,防杂草、灌木效果达95％,防火线上以草甘膦与调节膦或威尔柏混用为好。在室内生测表明:草甘膦+调节膦有增效作用,草甘膦具有解偶联剂作用,抑制膜上ATP酶活性。

Study on the Technology for Eliminating Weeds in Forest by Chemical Herbicides

Screenings of chemical herbicides to eliminate weeds in forests have been conducted in the nurseries, young stands, planting sites and fire preventing lines. In the Pine and Fir nurseries, Goal or Nitrophen was used to kill the weeds with an effect of over 90 %; Pines, Firs,broa-dleaf trees and fruit tr-ees, which are high than 1 m, were treated with leaf or needle spray of Glyphosate with an effect of over 85 %; on the planting sites, leaf surface sprays of Glyphosate, 2,4-DA, Glyphosate + Fosamine or Velpar + Glyphosate were treated to kill weeds and shrubs with an effect of 95 %; on fire preventing lines, Glyphosate + Forsamine or Glyphosate + Velpar would achieve good results.
