摘  要:
研究表明,狗尾草种子在5~30cm土层中经一年时间存活率为2%~18%,反枝苋为21%~59%。反枝苋种子埋藏三年半时间基本失去发芽能力,狗尾草埋藏五年后仍有10%的种子具有发芽能力。狗尾草出苗最适深度为1~3cm,反枝苋为2cm。杂草种子出苗最适宜的土壤相对湿度为40%。

摘  要:
In order to control weeds through cultivation, the soil germination conditions of green bristlegrass(Setaria viride L.)and redroot amaranth(Amaranthus retroflexus L.)were discussed in this paper. Results showed that the weed seed survivel rate in one year was 2%~18% for green bristlegrass, and 21%~59%for redroot amaranth in the soil depth of 5~30 cm. Within three years, 10% of the green bristlegrass seeds in the soil still had the ability of germination while no seeds of the redroot amaranth survived. The most suitable depth in soil for easy germination was 1~3 cm for the green bristlegrass, and 2 cm for the redroot amaranth. The optimum relative of soil for was 40% for the weed seeds germination.
