鉴于铜素营养与小麦雄蕊育性关系密切,故有可能利用铜螯合剂使小麦缺铜,从而达到杀雄的目的。[Graham,1986]。本研究旨在明确现有几种铜螯合剂对小麦生育的影响,并分析它们作为小麦杀雄剂的可能性。 1.试验方法和主要结果试验于1987～1989年在浙江农业大学温室旁进行。第一年(1987～1981)主要目的是筛选最有效的铜螯合剂,并研究适宜的使用时期、浓度与方法。冬小麦品种浙农大105播于装有15kg小粉土的盆钵(25cm×30cm)中,播前施饼肥10g,尿素1g,氯化钾0.75g。出苗后删苗至每盆5株。供试的铜螯合剂有苯并三氮唑、鲁必胺酸、新铜铁试剂、吡喀啶二硫代氨基甲酸铵和-安息香肟。处理分4种:1)5种药剂在拔节期土施,用量50mg/kg土;2)苯并三氮唑分播前、分蘖期,拔节期和孕穗期土施,用量同上;3)苯并三氮唑在拨节期和孕穗期分土施与叶面喷施,用量
In view of copper nutrition and wheat stamen fertility are closely related, it is possible to use copper chelating agent to make copper lack of wheat, so as to achieve the purpose of killing male. [Graham, 1986]. This study aimed to clarify the effects of several existing copper chelators on wheat growth and to analyze their potential as wheat killing agents. 1. Test Methods and Main Results The experiment was carried out in the greenhouse of Zhejiang Agricultural University from 1987 to 1989. The first year (1987 ~ 1981) the main purpose is to screen the most effective copper chelator, and study the appropriate period of use, concentration and method. The winter wheat variety Zhe Nongda 105 was sown in a pot (25 cm × 30 cm) packed with 15 kg of fine silt, with 10 g of cake fertilizer, 1 g of urea and 0.75 g of potassium chloride. After emergence seedlings to 5 per pot. The tested copper chelators were benzotriazole, ruzilic acid, a new copper and iron reagent, pyridoxine dithiocarbamate and - benzoin oxime. The treatment was divided into 4 kinds: 1) 5 kinds of chemicals were applied in the jointing stage with the dosage of 50mg / kg soil; 2) Before and after the treatment of benzotriazole at the tillering stage, jointing stage and booting stage, And triazole in the dial-pitch and booting stage soil and foliar application, dosage
