- 摘要:
- 采用田间小区试验，分别设禾本科杂草、阔叶杂草、混合杂草自然生长区及无杂草危害区，形成不同的杂草群落，研究了不同杂草群落危害对春玉米生长及产量损失的影响。结果表明：杂草的生长发育受土壤等环境条件的影响，不同年份相同杂草的生长量有较大差异。不同杂草类型之间存在明显的生存竞争，在混合杂草自然生长群落中，绝大多数禾本科杂草和阔叶杂草的生长状况均明显比单一杂草群落中的生长状况差，表现为混合杂草群落中杂草的单株鲜重明显低于单一群落中相同杂草的单株鲜重。不同杂草群落危害对春玉米产量损失的影响有较大差异，影响力由强到弱（作物产量损失率由高到低）的顺序为：混合杂草自然生长群落＞禾本科杂草自然生长群落＞阔叶杂草自然生长群落。春玉米产量损失率与杂草的数量和生长量呈正相关。杂草的数量越多、生长量越大，春玉米的产量损失率越高。
- Abstract:
- Using the method of field plot test,respectively designed the grass,broadleaf weeds,mixed weeds natural growth zone and no weed damage zone,forming different weed community,the effects of different weed community disserve on spring maize growth and yield loss were studied.The results showed that soil and other environmental conditions affected the weed growth,so that the same weed growth rate was great difference in different years.Different types of weeds existed survival competitions.Most of grass and broad-leaved weed growth status were all significantly inferior in the mixture of natural growth of weed community than single weed community.The fresh weight per plant was significantly lower in the mixed weed community than in the single community.There was great difference effect on spring maize yield loss caused by different weeds community disserved.The influence from strong to weak(crop yield loss rate from high to low)of the order was:mixed weeds natural growth community>grass natural growth community>broadleaf weeds natural growth community.The relationship of spring maize yield loss rate was positively related with weed population and growth quantity.The more the number of weed and the growth amount of weeds,the higher rate of spring maize yield loss.
