渭北旱塬油菜茎象甲药剂防治方法与效果

油菜茎象甲田间防治试验表明：５０％氧化乐果乳剂１０００倍液和２．５％溴氢菊酯乳剂４０００倍液喷雾对成虫的防治效果较好。春季始盛期喷药优于秋季。氧化乐果羊毛脂、久效磷羊毛脂和氧化乐果聚乙烯醇涂茎剂防治幼虫的效果较好。化学防治应以春季成虫出土始盛期药剂喷雾为主，辅以幼虫初期涂茎剂防治。     

国外松芽流脂病发生与防治

近年来,浙江省局部地区国外松纯林受芽流脂病危害较为严重.通过定点现察、分离培养、光镜检查、电镜现察、微量元素测定和用硼砂防治罹病松树等方法,基本查清国外松芽流脂病在浙江省的发生情况,明确了国外松芽流脂病的3种症状顶芽枯死型、丛枝型和枯梢型.国外松芽流脂病是由于松树自身和土壤中的微量元素--有效硼含量不足引起的生理性病害.用喷洒3.0g@kg-1或5.0g@kg-1硼砂溶液防治该病效果显著,防治区病情指数与对照相比平均下降38.5,松树的年平均高生长量也比对照大14.8cm.表4参4

SONOGRAPHY OF THE MUSCULOSKELETAL SYSTEM IN DOGS AND CATS

Sonography of the musculoskeletal system in dogs and cats was undertaken to evaluate the application of this imaging procedure in orthopedics. In most of the patients a 7,5 MHz linear transducer was used because of its flat application surface and its resolving power. The evaluation of bone by sonography is limited, but sonography can provide addition information regarding the bone surface and surrounding soft tissue. Ultrasound is valuable for assessing joint disease. Joint effusion, thickening of the joint capsule and cartilage defects can be identified sonographically. It is also possible to detect bone destruction. Instabilities are often identified with the help of a dynamic examination. Soft tissue abnormalities of the musculoskeletal system lend themselves to sonographic evaluation. Partial or complete muscles or tendon tears are able to be differentiated and the healing process can be monitored. Most of the diseases that are in the area of the biceps or the achilles tendon, such as dislocation of the tendon, old injuries with scarification, free dissecates in the tendonsheath, tendinitis and/or tendosynovitis can be differentiated by sonography. In addition, with clinical and laboratory findings, it is often possible to make a correct diagnosis with ultrasound in patients with abscesses, foreign bodies, hematomas, soft tissue tumors and lipomas.
