根据棉花各生长阶段水分供应充足与否对生长中心影响十分明显的特点,可将"干播湿出"膜下滴灌棉田灌水的主导作用划分为3个功能,即"长根水(苗蕾期)、健根水(始花期)和养根水(产量贡献水,花铃期)"。在苗期与蕾期,棉... 根据棉花各生长阶段水分供应充足与否对生长中心影响十分明显的特点,可将"干播湿出"膜下滴灌棉田灌水的主导作用划分为3个功能,即"长根水(苗蕾期)、健根水(始花期)和养根水(产量贡献水,花铃期)"。在苗期与蕾期,棉花的生长中心为根系,此期的水分供应充足与否直接影响到棉花群体的根系质量。因此,该阶段水分作用主要贡献于根系生长,可称之为"长根水";始花前后水分供应的主要作用在于解除由于自出苗以来土壤水分持续下降对棉花生长造成的水分胁迫,促进高产棉田应有的棉花根型结构与质量及地上部分应有营养体的建成,此期的水分供应称之为"健根水";自盛花以后到吐絮期,棉花生长重心为棉铃形成与产量密切相关的群体生殖生长,此期的水分供应目标在于保持根系较好的活力,为地上部分提供足够的水分与养分,故称之为"养根水"。在灌溉量的确定上,"长根水"即播后即灌的出苗水(450~600 m^3/hm^2)和"健根水"即始花前后棉花生长发育期的第1次灌溉(500~700 m^3/hm^2),以不造成深层渗漏为原则使根层(0~100 cm)尽可能多地持有水分。自生长阶段的第2次灌溉起即进入"养根水"管理阶段,应采取"轻勤浅"(灌水量300~400 m^3/hm^2,灌溉周期7~8 d,湿润锋深度60 cm左右)的灌溉方法 ,每次灌溉前的滴灌带下方0~60 cm土壤含水量约75%的田间持水量,使膜下滴灌棉花的产量潜力得到最大可能的挖掘。在棉花3个明显不同的生长发育阶段,水分对棉花生长发育的生理生态意义不相同,在水分管理上应有明显的区别性。 展开更多

[Objective]The study was carried out for providing good method to detect ratoon stunting disease(RSD)in virus-free seedcane of Saccharum officinarum.[Method]PCR method was used for the detection of RSD in virus-free seedcane of sugarcane.[Result]During the different growth stages of healthy virus-free seedling including proliferation stage,rooting stage,sand culture stage and temporary planting stage,the RSD detection results were negative.PCR detection sensitivity in the present study showed that PCR could detect RSD pathogen in the solution with bacterium concentration 10-3.[Conclusion]PCR method showed a good specificity and higher sensitivity,so it was suitable for the batch detection in the production of healthy virus-free seedlings of sugarcane. 展开更多

Healthcare fraud, waste, and abuse losses are estimated to be as much as $700 billion per year. These losses contribute to rapidly increasing healthcare costs for all Americans and the lack of healthcare or the malpractice of healthcare for money motivations can result in death. The purpose of this article is to describe several different types of healthcare frauds that occurred and to offer suggestions related to the prevention and/or detection of this type of fraud. With a better understanding of the frauds that can take place, auditors can help protect society from both unfair healthcare costs and medical problems. 展开更多

This paper aims to calculate Argentinean consumers' willingness to pay (WTP) for organic fresh chicken in the domestic market, by applying the Contingent Valuation approach and with a view to providing some useful insights for promoting organic chicken production and consumption in Argentina. A binomial logit model was estimated using data from a consumer survey conducted in Buenos Aires City, Argentina. Willingness to pay is explained by the consumption of organic products, health risk perceptions, concerns about production processes and also regulation issues, and label reading. The WTP calculation reveals a mean value of 21.4%/kg and a median value of 19%/kg. These results indicate that organic chicken is positively valued by consumers. In fact, it provides the nutritional and product origin information that buyers require and they consider it a safer option than conventional chicken. 展开更多

OBJECTIVE: To observe long-term functional recovery after contralateral C7 transfer. METHODS: From August 1986 to July 2000, 224 patients with brachial plexus avulsion injuries were treated with contralateral C7 transfer in our department. Thirty-two patients were followed up for over 2 years for evaluation of the following items: 1 influence on healthy limb function; 2 sensory and motor recovery of the recipient nerves in the affected limb; and 3 coordination between the healthy and affected limbs. RESULTS: There was no impairment of healthy limb function. Functional recovery of the recipient area reached > or =M3 in 8 patients (8/10, 80%) after musculocutaneous nerve neurotization, > or =M3 in 4 patients (4/6, 66%) after radial nerve neurotization, > or = M3 in 7 patients (7/14, 50%) and > or = M3 in 12 patients (85.7%) after median nerve neurotization, and > or = M3 in 1 patients (1/2, 50%) after thoracodorsal nerve neurotization. Synchronic contraction of the affected limb with the healthy limb occurred within 2-3 years in 12 patients, within 5 years in 13 patients, and over 5 years in 7 patients. CONCLUSION: Contralateral C7 transfer is an ideal procedure for the treatment of brachial plexus root avulsion injury. Selection of the whole root or the posterior division as neurotizer and a staged operation are the major factors influencing treatment outcome. 展开更多
