The special weed-killer fertilizer for wheat is a pesticide-fertilizer which has the weed control function.The results of many years separate study for the formula of nutriment and weeding showed that there were two formulas of the special weed-killer fertilizer.One is mz4-C6 for base fertilize,the other was mz4-C1 for dressing fertilizer.It was effective for controlling weeds in wheat field and safety for rape of follow crops.The mz4-C6 of base fertilizer was suitable for drought area.The result showed that the control effect of individual plant and fresh weight of weeding were 73.3%,83.4%.The increase rate of wheat and rape of follow crops were 23.16%,4%;The mz4-C6 of dressing fertilizer was suitable for irrigable land.The result showed that the control effect of individual plant was 71.24%.The increase rate of wheat and rape of follow crops were 13.45%,27.52%.%小麦除草专用肥是具有除草功能的药肥,经过几年的小麦除草专用肥营养配方和除草配方分步研究,优选出除草效果好、对后茬油菜安全的mz4-C6(基肥)和mz4-C1(追肥)两个小麦除草专用肥配方,其中mz4-C6(基肥)适合旱地施用,株防效达73.3%,鲜重防效达83.4%,小麦增产23.16%,后茬油菜增产4%;mz4-C1(追肥) 适合水浇地施用,总株防效71.24%,小麦增产13.45%,后茬油菜增产27.25%.
