兰氏布伦螨Brennandania lambi(Krczal)是江、浙、沪、川等省市蘑菇上毁灭性的害螨。由于该螨体形微小,菌种带螨不易发现,一旦带螨菌种播入菇床将会绝收,为了减少损失,我们做了菇床上兰氏布伦螨的防治适期试验,现将结果报告如下。 一、材料与方法 (一)供试材料 ①害螨:经过人工纯化后,在蘑菇栽培种上饲养的兰氏布伦螨(各螨态均有)。②药剂:保菇粉,上海市农科院植保所提供。 (二)试验方法 以箱式栽培模拟床式栽培,面积为0.144m~2的长方形有孔塑料箱,9月11日每箱装培养料3kg。分播种期、覆土期用药两种处理。①播种期用药:装料当天(9月11日)每箱撒药粉5g(折35g/m~2),并抖入料中5cm,然后每箱播蘑菇1906号棉子壳栽培种150g(无螨菌种),再接螨17663头/箱(折122660头/m~2),其中95.77％为螨卵。②覆土期用药:
Brennandania lambi (Krczal) is a devastating pest of mushrooms in the provinces of Jiangsu, Zhejiang, Shanghai and Sichuan. Because of the small body shape of the mite, fungi with mites is not easy to find, once the mites species will penetrate into the mushroom bed will be closed, in order to reduce losses, we have done Mushroom bed brucellosis prevention and control of appropriate tests, report the results as follows. Materials and methods (a) the test material ① pest mites: After artificial purification, cultivated in mushrooms on the Bruker mites (all mites state). ② Pharmacy: Paul mushroom powder, provided by the Shanghai Academy of Agricultural Sciences plant protection. (B) test methods to box-type cultivation of simulated bed-type cultivation, an area of 0.144m ~ 2 rectangular perforated plastic box, September 11 each box of culture material 3kg. Seed planting period, covering the period of two kinds of medication. ① sowing period of medication: the day of loading (September 11) each box sprinkling powder 5g (folded 35g / m ~ 2), and shaking into the material 5cm, and then boxed sowing mushroom No. 1906 cotton seedling 150g Mites species), then pick mites 17663 head / box (fold 122660 / m ~ 2), of which 95.77% mite eggs. ② Covering medication:
