試驗証明,麦株上麦稈蝇的着卵率与为害率,以小麦孕穗以前的阶段为大,而且愈前愈大。田間冬小麦从出現第二节到抽旗叶的阶段,是危险受害期。防治与测报工作应考虑这一阶段时間。不同品种的受害程度,与品种抽旗期的迟早有关;抽旗到抽穗的生育速度是品种受害程度的重要标誌。通过品种比較試驗,看出品种被害程度与各品种抽旗期与成虫高峯期偏差日数,加上抽旗到抽穗历期的总值有高度正相关,其直线迴归为:y=0.41x-2.77,这两个指标也可作为测报与选育抗虫品种的参考。采取选用品种,調节播种期,适当施肥等农业技术措施,提早小麦生育期,可以有效地控制与減輕麦稈蝇的为害。
Experiments show that wheat stalks on the oak rate and rate of damage to wheat booting before the stage is large, and the greater the greater the more. The stage of field winter wheat emergence from the second quarter to the flag-raising stage is a dangerous period of victimization. Prevention and detection work should be considered at this stage of time. The degree of victimization of different breeds is related to the sooner or later date of the variety flagging. The birth rate of flagging to heading is an important indicator of the degree of breed damage. Through the variety comparison test, we can see that the degree of the damage of varieties is highly positively correlated with the days of deviations from the flag-staging and adult peak of each breed plus the total value from sampling to heading. The linear regression is y = 0.41x- 2.77, these two indicators can also be used as a reference to report and breeding insect-resistant varieties. Take the selection of species, adjust the sowing period, the appropriate fertilization and other agricultural technology measures to early wheat growth period, you can effectively control and reduce the harm of straw flies.
