基于后茬作物安全性的小麦除草专用肥研究

Study on Formula and Follow Crops Safety of Special Weeding Fertilizer for Wheat Field

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%。

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 Cl 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%.
