The control of is critical to ensuring food security. This study investigated a range of different aspects of the biology of , including its emergence characteristics, population development dynamics, and its impact on wheat yield. Moreover, the efficacy of different herbicides and cultural control measures for managing was explored. Through laboratory cultivation and statistical analysis of the emergence rate of , it was found that its emergence rate significantly increased when temperatures ranged from 10 °C to 20 °C and the environmental osmotic potential fell between -0.1 MPa and -0.5 MPa-conditions similar to those found in wheat fields. Additionally, by recording the emergence rates at different depths, emergence was found to occur optimally at a sowing depth of 1-5 cm, which aligns with the shallow rotary tillage currently employed in wheat production. The weed was also found to be tolerant to weakly acidic and alkaline environments, while also presenting with moderate salt tolerance. Through field experiments, it was found that, upon spreading to new areas, rapidly expanded its population size. While its impact on wheat yield was relatively mild during the early stages of growth, it escalated to severe outbreaks with the passage of time. Field experiments were conducted to test the efficacy of five herbicides on weed control. The analysis indicated that Mesosulfuron-methyl was the only effective herbicide in controlling . Adopting three two-year-three-crop rotation patterns reduced the density of from 186 stems/m to 11-15 stems/m. Watering-induced emergence also proved effective. The most effective watering was performed 15 days before sowing. Deep plowing was another effective measure. The deeper the plowing, the lower the emergence of . Delayed sowing time resulted in the additional suppression of the emergence of .
对[某种杂草名称]的防治对于确保粮食安全至关重要。本研究调查了[某种杂草名称]生物学的一系列不同方面，包括其出苗特性、种群发展动态及其对小麦产量的影响。此外，还探索了用于防治[某种杂草名称]的不同除草剂和栽培控制措施的效果。通过实验室培养和对[某种杂草名称]出苗率的统计分析发现，当温度在10℃至20℃之间且环境渗透势在-0.1MPa至-0.5MPa之间时，其出苗率显著增加，这与麦田中的条件相似。此外，通过记录不同深度的出苗率，发现[某种杂草名称]在1-5厘米的播种深度下出苗最佳，这与目前小麦生产中采用的浅旋耕方式一致。还发现这种杂草对弱酸性和碱性环境具有耐受性，同时也具有中度耐盐性。通过田间试验发现，[某种杂草名称]传播到新地区后，其种群规模迅速扩大。虽然在生长初期对小麦产量的影响相对较小，但随着时间的推移，其影响升级为严重爆发。进行田间试验以测试五种除草剂对杂草防治的效果。分析表明，甲基二磺隆是防治[某种杂草名称]的唯一有效除草剂。采用三种两年三熟的轮作模式可将[某种杂草名称]的密度从186株/平方米降低到11-15株/平方米。浇水诱导出苗也被证明是有效的。最有效的浇水是在播种前15天进行。深耕是另一项有效措施。深耕越深，[某种杂草名称]的出苗率越低。推迟播种时间也会进一步抑制[某种杂草名称]的出苗。
