果树套种春小麦,如春小麦苗期除草剂使用不当,会对果树或下茬双子叶作物产生药害,严重影响果树的生长,可导致下茬双子叶作物减产甚至绝收。一、套种前化除技术一般不在果树行间使用草甘膦或克无踪等灭生性的除草剂。实践证明,在果树行间长期使用草甘膦 Fruit tree intercropping Spring wheat, such as the improper use of spring wheat seedling herbicide, will produce phytotoxicity to the fruit tree or the diced monocotyledonous crops, seriously affecting the growth of the fruit tree, which may lead to the reduction or even the absolute yield of the diced monocotyledonous crops. First, in addition to intercropping before the technology is generally not used in the fruit trees between glyphosate or no trace of such a destructive herbicide. Practice has proved that long-term use of glyphosate between fruit trees
