苗前除草剂与土壤耕作方式对麦茬谷子杂草及苗期生物学性状的影响
|
摘要
为有效防除麦茬谷田杂草,降低杂草对谷子的影响及人工除草成本,采用大田随机区组方法开展了苗前除草剂与土壤耕作方式对麦茬谷田杂草及苗期生物学性状的影响研究。结果表明:晋南麦茬谷田苗后15、15～30、30～45天其新生杂草数量分别占苗后45天新生杂草数量的64.77%、26.14%、9.09%;10%单嘧磺隆施药量2100 g/hm~2土壤封闭对苗后15、15～30天新生杂草数量及全生育期杂草生物产量具有显著的抑制效果;10%单嘧磺隆施药量1500 g/hm~2、1800～2400 g/hm~2土壤封闭分别对谷子苗期生物学性状(株高、单株次生根等)有促进、抑制生长作用。可得出结论:10%单嘧磺隆施药量2100 g/hm~2对麦茬谷田土壤封闭具有显著的抑制杂草效果。
To control weeds in wheat stubble millet field, reduce weeds influence on millet and the weeding cost, the effect of different pre-emergence herbicides and soil tillage methods on weeds and biological characters of wheat stubble millet are studied with randomized block design. The results showed that: the number of new weeds after 15, 15-30, 30-45 d was 64.77%, 26.14%, 9.09% of that of 45 d in south Shanxi;2100 g/hm~2 of 10% Monosulfuron with soil sealing had dramatic suppressing effect on new weeds of 15, 15-30 d and weeds in whole growth period; 1500 and 1800-2400 g/hm~2 of 10% Monosulfuron had respectively promoting and inhibitory effect on biological characters(plant height, individual plant secondary roots) at millet seedling stage. In conclusion, 2100 g/hm~2 of 10% Monosulfuron with soil sealing can significantly inhibit weeds in wheat stubble millet field.
