Abstract: The briquette of the leaf leaves, the outer fruit housing, the outer fruit shell were selected, and the three pioneers, ryegrass and purple granules weresubmitted to the three pioneers, the three pioneers of the Avena sativa L,Lolium perenne L and the Medicago sativa. The growth was significantly better than the Medicago sativa and Lolium perenne L, and the root length inhibition rate was 74.47% at 0.40 mg/mL treatment, which was significantly lower than the root length inhibition rate of purple was 78.16%.

Key words: Jatropha curcas Linn, Avena sativa L, Lolium perenne L, Medicago sativa, germination growth
