释放日本壁蜂授粉,是利用生物增产、取代人工和蜜蜂给果树授粉的一项成功的新技术。为掌握应用好这项技术,现提出以下技术操作要点和应注意的事项供参考。 1.药剂使用 搞壁蜂授粉的果园,必须在放蜂前10～15天打一次杀菌、杀虫剂,放蜂授粉期间,禁止打任何药剂。 2.巢管规格 释放壁蜂用的巢管(纸制管或芦苇管),必须一头封闭,一头开口;巢管长度15～17cm,口径6～7mm,其口径大或小都影 The release of Japanese wall bee pollination is a successful new technology that uses bio-stimulation to replace artificial and bee pollinating fruit trees. To master the application of this technology, the following technical operations are proposed points and should pay attention to the matter for reference. 1. The use of pesticides to engage in wall pollination of orchards, bee 10 to 15 days before the bees hit a bactericidal, insecticide, bee pollination, banning any agent. 2. Specifications of the nest pipe wall tube used to release the nest pipe (paper tube or reed pipe), must be a closed head, an opening; nest tube length 15 ~ 17cm, caliber 6 ~ 7mm, the caliber of large or small shadow
