- 摘要:
- 研究表明, 狗尾草种子在5 ～ 30 cm 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 ～ 3 cm , 反枝苋为2 cm 。杂草种子出苗最适宜的土壤相对湿度为40 %。
- Abstract:
- In order to cont rol weeds through cultivation , the soil germination condi tions of g reenbristlegrass(Setaria vi ride L .)and redroot amaranth(Amaranthus ret rof lexus L .)were discussed inthis paper .Results showed that the weed seed survivel rate in one year w as 2 %～ 18 % for g reenbristlegrass , and 21 %～ 59 %for redroot amaranth in the soil depth of 5 ～ 30 cm .Within three years,10 % of the g reen bristleg rass seeds in the soil still had the ability of germinat ion w hile no seeds of theredroo t amaranth survived .The most sui table depth in soil for easy germinat ion w as 1 ～ 3 cm for theg reen bristleg rass , and 2 cm for the redroot amaranth .The optimum relative of soil for w as 40 % forthe w eed seeds germination
