为掌握650 g·L－1夜蛾利它素饵剂对棉铃虫等夜蛾科害虫的诱集效果，在新疆生产建设兵团第四师和第八师的4个团场开展了示范试验。结果表明，650 g·L－1夜蛾利它素饵剂在棉铃虫羽化高峰期使用，对棉铃虫、三叶草夜蛾等夜蛾科害虫诱集效果明显，在药后2～5 d诱集数量达到最高，药效期超过7 d，且能降低棉田内棉铃虫落卵量、幼虫虫口数量及蕾铃被害率。650 g·L－1夜蛾利它素饵剂诱虫可作为棉铃虫监测手段、绿色防控和农药减量控害技术在新疆棉花生产中推广应用。 相似文献

棉叶螨是东疆垦区棉花主要害虫之一。随着植棉年限的增加,棉叶螨危害呈不断加重的趋势。在防治上一般以化学防治为主,不但农药品种多,而且用药量也在不断增加。该方法投资大,且对环境造成污染,而采用生物防治的方法,可避免上述现象发生,形成“以益控害”的良性循环。本试验示范的目的主要是明确捕食螨防治棉田害螨的效果及其使用技术,加快该技术在本地的推广应用。 相似文献

Sorghum is a good source of phenolic compounds with a variety of genetically dependent types and levels including phenolic acids, flavonoids, and condensed tannins. Most sorghums do not contain condensed tannins, but all contain phenolic acids. Pigmented sorghums contain unique anthocyanins that could be potential food colorants. Some sorghums have a prominent pigmented testa that contains condensed tannins composed of flavan-3-ols with variable length. Flavan-3-ols of up to 8–10 units have been separated and quantitatively analyzed. These tannin sorghums are excellent antioxidants, which slow hydrolysis in foods, produce naturally dark-colored products and increase the dietary fiber levels of food products. Sorghums have high concentration of 3-deoxyanthocyanins (i.e. luteolinidin and apigenidin) that give stable pigments at high pH. Pigmented and tannin sorghum varieties have high antioxidant levels that are comparable to fruits and vegetables. Finger millet has tannins in some varieties that contain a red testa. There are limited data on the phenolic compounds in millets; only phenolic acids and flavones have been identified. 相似文献

种子加工、检验理论与技术现状及思考 总被引：3，自引：0，他引：3
种子加工及检验是种子向市场流通的关键，是商业化育种中赋予种子商品属性不可或缺的环节。种子加工、检验理论与技术的研究是完善种业产业链、实现规模化商业育种、夯实“育繁推一体化”种业科学的重要一环。中国的种业科学技术体系正在形成与完善之中，受制于行业发展水平，种子加工及检验理论与技术相对薄弱。本文回顾了种子加工及检验理论与技术研究发展历程，提出了完善中国种业科学发展的策略与建议。围绕种业发展的需要，在做好品种优质化繁育的基础上，分析种子加工及检验理论与技术的新方向和新需求，加强种业应用性研究，建立先进的种子质量检验体系，研制适合现代种业发展需求的种子加工设备，打造种子加工产业标准化生产体系，完善种业科学技术学科建设，促进种业产业持续健康发展。 相似文献

Summary Between 1993 and 1998 205 different potato cultivars and 1220 accessions/genotypes of wild and cultivated potato species from
the IPK Genebank Gatersleben were evaluated. Parameters interesting for starch isolation and especially for the use of starch
were determined. Altogether, there was a higher variability in wild potato species than in cultivated potatoes for all characteristics
investigated: dry matter content, starch content, protein content, amylose content and mean particle diameter of starch granules. 相似文献

Seed processing and testing hold the key to the market circulation of seeds, and are an indispensable link in commercial breeding to endow seeds with commodity attributes. The research of seed processing and testing theory and technology is an important link in improving the seed industry chain, realizing large-scale commercial breeding and consolidating the seed industry science of ‘integration of breeding, propagation and promotion’. The scientific and technological system of seed industry in China is being formed and perfected, which is subject to the development level of the industry. The theory and technology of seed processing and testing are relatively weak. We reviewed the development of seed processing and testing theory and technology, and put forward strategies and suggestions to improve the sound development of China’s seed industry. In order to meet the needs of seed industry development and on the basis of high quality breeding of varieties, the new directions and demands of seed processing and testing theory and technology were analyzed. We will work to strengthen the applied research of seed industry, establish advanced seed quality inspection system, improve seed processing equipment suitable for the development needs of modern seed industry, establish standardized production system of seed processing industry, develop the scientific and technological disciplines of seed industry, and promote the sustainable and healthy development of seed industry. 相似文献
