<正>笔者介绍内蒙古土默特左旗蜜粉源情况,以正常年份花期为准,依据开花顺序讲述。一、春季蜜粉源1.榆树、杨树为全年最早粉源植物,3月底扬粉,花期8～10天,虽无蜜,但粉源对春繁作用很大。2.山桃4月8日始花,花期8～10天,有蜜有粉,蜜蜂采集兴奋,对春繁有促进作用。3.杏树4月13日始花,花期8～10天,为主要辅助蜜粉源植物。群强 相似文献

前几年我地没有主要蜜粉源植物在秋季开花,一些零星开花的蜜粉源植物也是寥寥无几。最近几年,不知什么原因有一种“拉巴蔓”的野生植物在我地开花结果,它藤上长着刺,无蜜但花粉丰富,如利用得当,一般年份可收5～6框越冬蜂。可是怎样利用好这一粉源呢?众说不同:有蜂友利用它吐粉丰富的优势在秋繁时脱粉,以备翌年春繁;有的蜂友在花期结束时用巢内贮粉繁蜂一段时间等等。我认为这些做法有点不妥,下面谈谈我利用它秋繁的做法。刚开始的时候,我也掌握不住它开花的迟早、花期的长短,弯路走得不少。后来通过三四年的繁蜂实践与探讨,摸索出了用“拉巴… 相似文献

蜜粉源植物是发展养蜂的物质基础。如果蜜粉源植物丰富,就可以把蜂养好。即使养蜂经验再丰富,如果缺乏蜜粉源,也不能把蜂养好,更谈不上高产。到一个新的地区养蜂,对于蜂场周围3.5—4公里地以内的各种蜜粉源植物,开花期和泌蜜规律要有所了解。除了观察返巢的蜜蜂后足携带的花粉团大小之外,还可以开箱看一下,巢脾产卵圈外围新粉多少,也可以跟踪蜜蜂的飞翔方向,观察它们在花间的采集动作,是采蜜还是采粉。有条件的可以把蜜蜂所采的花摘几朵,把花朵上的花粉粒和密蜂后足上的花粉 相似文献

在闽中莆田的平原地区,小暑过后,骄阳似火,气候炎热,外界很少有蜜粉源植物开花,蜂群一般处于断粉断子状态,群势下降到全年最低点,这就是养蜂人常称的“苦七绝八”的艰难时期(但有些地方有小叶桉,约在小暑前后开花泌蜜,还有粉,对繁蜂有利,中蜂还可采到商品蜜。)。可喜的是,闽中沿海地区绿肥作物田菁约在立秋前数天开花,虽蜜歉但粉足,仍不失为蜂群度夏难得的一种大面积粉源。田菁,当地群众俗称为“海松柏”,一年生草本植物,一般用作绿肥,株高可达2￣3m;叶片呈椭圆形,对生,白天舒展,晚上闭合,有似“怕羞”样子;遍株皆绿,花黄色,开花时节万绿丛… 相似文献

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection. 相似文献

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded. Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario. Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously. 相似文献

In late November 1991, 1883 clinics in Canada were sent a questionnaire to assess the status of Dirofilaria immitis in dogs in 1991 and there was a 60.0% response. There were 344,031 dogs tested for heart-worm (HW), 627 were found infected and the prevalence of HW infection was 0.18%. There were 417 dogs with HW in Ontario, 116 in Manitoba, 38 in Quebec, 53 in British Columbia, three in Alberta, and one in Nova Scotia. In British Columbia, all of the infected dogs but one were from the Okanagan valley which, as from 1991, is a new focus of infection in Canada. Most dogs with HW had not been on preventive medication in 1990, and the prevalence among dogs tested and unprotected was 0.59%. That prevalence was considerably higher in endemic areas. Companion dogs, over three years of age and maintained primarily outdoors in rural areas, were most frequently infected. One cat was diagnosed with D. immitis and 33 dogs had Dipetalonema reconditium. 相似文献

Heartworm was reported from all provinces except Prince Edward Island, Newfoundland and Saskatchewan but most (1126) of the cases were in Ontario. Southwestern Ontario continued to be the primary focus of the infection in Canada. From Quebec, 91 cases were reported mostly from and around Montreal. From Manitoba, 19 cases were reported from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 28% of the cases were observed with clinical signs of heartworm disease and 78% had a history of not having left Canada. 相似文献

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded. Of 247,716 dogs tested, 394 had D. immitis microfilariae and 51 were amicrofilaremic for a total of 445 cases and heartworm prevalence of 0.17%. Most (408) of these dogs had no preventive medication and the prevalence among dogs tested and unprotected was 1.01%. That prevalence was considerably higher in endemic areas. Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas. About 75% of the cases had never left Canada, 26% had clinical signs and 125 were not treated. Heartworm was reported from British Columbia, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland, but 383 cases were in Ontario. South-western Ontario was the primary focus of infection. There were 33 cases in Quebec and 24 in Manitoba, mainly found in and around Metropolitan Montreal and Winnipeg respectively. 相似文献
