In the orchard – Picking flowers
Male kiwifruit flowers are picked by hand. One picker can collect 30–40 kg of flowers a day, and up to 800 pickers work at the busiest time. PollenPlus? gets about 80 tonnes of flowers from its orchards in the western Bay of Plenty. One picker fills up to four of these 10 kg bags a day.
成績單
在果園里——采花
雄獼猴桃花是手工采摘的。一名采摘者每天可以采摘30-40公斤的鮮花，最繁忙的時候多達(dá)800名采摘者在工作。PollenPlus?從其位于豐盛灣西部的果園中收獲了約80噸鮮花。一個撿拾器每天可以裝滿四個10公斤的袋子。

At the mill – Collecting anthers
Each bag of flowers is fed into a machine that lightly chops them up. A spinning drum separates the small anthers, which contain the pollen, from the rest of the flower parts. The anthers fall into a tray beneath the drum. The flowers pass through three drums to make sure all the anthers are collected.
在磨坊里——收集花藥
每袋花都被送入一臺機器，機器會輕輕地將它們切碎。一個旋轉(zhuǎn)的鼓將含有花粉的小花藥與花的其他部分分開。花藥落入鼓下的托盤中?；ù┻^三個鼓，以確保所有的花藥都被收集起來。

Drying anthers
The anthers from beneath the separating drums are spread evenly onto trays for drying. About 1 kg of anthers goes on each tray. The trays are then put in racks, where they are dried at 30 °C for 20 hours.
干燥花藥
將分離桶下方的花藥均勻地鋪在托盤上晾干。每個托盤上大約有1公斤花藥。然后將托盤放在架子上，在30°C下干燥20小時。

Purifying pollen
Dried anthers and pollen are vacuumed up into a cyclone separator. A spinning stream of air separates the fine pollen from the larger particles of the anthers. Pollen from the cyclone separator is filtered to remove the last of the impurities.
凈化花粉
干燥的花藥和花粉被真空吸入旋風(fēng)分離器。旋轉(zhuǎn)的氣流將細(xì)小的花粉與花藥中較大的顆粒分開。旋風(fēng)分離器中的花粉經(jīng)過過濾，去除最后的雜質(zhì)。

Packaging
Pollen is packed into 250 g jars – this amount of pollen comes from about 25 kg of flowers. Just 1 gram of pollen contains about 5 million pollen grains. The pollen is frozen for storage. It will later be sent to kiwifruit growers in New Zealand and other countries.
包裝
花粉裝在250克的罐子里——這個數(shù)量的花粉來自大約25公斤的花朵。僅僅1克花粉就含有大約500萬個花粉粒?；ǚ郾焕鋬霰４?。隨后，它將被送往新西蘭和其他國家的獼猴桃種植者手中。

Testing
Every 2 kg of pollen is sampled to check that the pollen is viable (still able to pollinate female flowers). Samples of pollen are put in sugar solution for 2 hours, then examined under a microscope to see how many pollen tubes have grown. A viability of at least 80%, which is 80 pollen tubes per 100 pollen grains, is needed for the pollen to pass the test.
測試
每2公斤花粉取樣，檢查花粉是否存活（仍然能夠為雌花授粉）。將花粉樣本放入糖溶液中2小時，然后在顯微鏡下檢查有多少花粉管生長?；ǚ坌枰辽?0%的存活率，即每100個花粉粒有80個花粉管，才能通過測試。
