Of applications to clean ·马 Ruyou Caiqingchong Pieris rapae, the field of medicinal test, the test results showed : 20% of clean ·马 Ruyou Caiqingchong have good preventing and controlling effect, albeit one day after 1500 Beiye, 2000 Beiye, 2500 amounted to 96.45% Beiye-effective, 91.94%,89.45%; medicine after three days of anti-drug effect after seven days, respectively, to 99.02%,95.85%,92.94%; 98.56%,92.62,87.42% respectively.

应用20%氰·马乳油防治菜青虫Pieris rapae的田间药效试验，试验结果表明：20%氰·马乳油对菜青虫具有良好的防治效果，施药后1天1500倍液，2000倍液，2500倍液防效达96.45%，91.94%，89.45%；药后3天的防效分别达99.02%，95.85%，92.94%；药后7天分别为98.56%，92.62，87.42%。

The comparison test of this new methodwith spray inoculation method was conducted. The results showed the former method could increase the incidence ofdisease and uniformity than the latter one. Used cotyledon-brushing with conidial suspension and fungicide foliarspraying method, the EC 50 values of hexaconazole, myclobutanil, triadimefon, thiophanate-methyl and chlorotha lonil to Sphaerotheca fuliginea treated in different time after inoculation were determined; the results showed that 96 h was better time for disease severity evaluating.

比较了白粉病菌分生孢子悬浮液涂抹法和喷雾法接种黄瓜幼苗子叶的效果，结果表明，涂抹法发病率高，均匀度更好；测定了接菌后不同时间施药，白粉病菌对己唑醇、腈菌唑、三唑酮、甲基硫菌灵和百菌清等 5 种杀菌剂的敏感性，结果表明，接菌后 96h 施药较为敏感，测得的 EC 50 较小。

The respective baits were applied at dosages of 2, 3, and 2 kg/ha every 2 months.

本试验自第一次施药后两周起，每 2 个月再施药 1 次。

Laxiflora by ethanol and water on cucumber powdery mildew was best when the medicine was used 6 days later and the control and prevention effects were obviously decreased when the medicine was used 9 days later.

水柏枝的乙醇、水提取液对黄瓜白粉病的防治效果在施药6d后最好，施药9d后的治疗和预防的效果均明显下降。

Vanilla plant and soil were treated in a vanilla garden by spraying pesticide demethoate at 3 recommended levels N(625mg/L,2N,and 4N, and the residues of dimethoate in plant parts and in soil under field conditions were determined by gas chromatography.

田间试验条件下，以推荐浓度N（625 mg/L），2N（1 250 mg/L），4N（2 500 mg/L）三个施药浓度分别喷施处理植株和土壤，用气相色谱法分析乐果在香草兰植株和土壤中的残留动态。

It is 14 days and 7 days that the fipronil residue was below 0.01mg/kg in 30g/hm^2 treatment trials. Under the condition of 45g/hm^2 treatment, it is 30 days and 21 days that the residue was less than 0.01 mg/kg in Job's-tears seeds.

最终残留试验表明，在薏苡仁收获前14d或7d按30g/hm^2有效剂量施药，收获前30d或21d按45g/hm^2有效剂量施药，氟虫腈的最终残留量均低于0.01mg/kg。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
