"That's it, it's all right. ”

Xu Yi breathed a sigh of relief, this is okay, it doesn't seem to be much, and the structure is simple, even if it doesn't, the principle of looking at this thing is very simple, presumably if you find some information, you can make it yourself. Like that gauze, I cut it with a window screen and sewed it on a straw hat, and then for example, the knife, it is estimated that it is the same when I take a fruit knife and scald it with hot water.

Zhu Zhiwen looked at Xu Yi with some disapproval, and couldn't help laughing: "It's so simple, hehe, those are general equipment, these are specialized equipment, and different things need to be used according to different purposes." ”

Xu Yi looked at it, too, there were still a lot of things to say, so he humbly asked: "Then I have to trouble Mr. Zhu to help me introduce it, okay?"

"For example, our black bee originally had the blood of European bees. ”

"Could it be that this 'Northeast Black Bee' refers to the bees of Northeast Europe, I thought it was the bees of the Northeast region of our country. ”

Zhu Zhiwen laughed when he heard this, and said: "I really don't know, I'll give you a simple science popularization, Xiao Xu, do you know where the Caucasus is?"

Xu Yi replied according to his impression: "The Caucasus Mountains seem to be the dividing line between southern Europe and West Asia, but I forgot whether it is between Russia and Georgia." ”

"That's right, that's it, the Caucasian bee is native to the high valleys of the central Caucasus, mainly in the mountainous areas of Georgia, Azerbaijan and Armenia, where the winter is not too cold, the summer is hotter, the frost-free period is long, the annual rainfall is more, and gradually breeds a variety of bees adapted to the local living conditions, this black bee is just one of them. ”

"At the beginning of the last century, someone introduced dozens of boxes of Caucasian black bees from the east bank of the Ussuri River, stocked them in the area of the HLJ Rao River, and gradually multiplied and developed into more than ten apiaries and more than 1,000 boxes of bees of the black bee group, and in the long-term breeding process, the black bee also gradually changed, becoming adaptable to the climate characteristics of the cold and frost-free period in Northeast China, as well as local plant species and traits, and became a genetically stable Caucasian black bee variety, which is the origin of the Northeast black bee. ”

"Nearly 100 years of natural selection and artificial breeding, the Northeast black bee is a local bee species with typical morphological characteristics and biological characteristics formed in the specific ecological environment of the Raohe area, through natural selection and artificial cultivation, which has been very different from the original Caucasian black bee, so it was officially named 'Northeast Black Bee', which is also the only local excellent bee species in China. ”

"In ninety-seven years, the State Council issued an order to establish a national Northeast Black Bee Nature Reserve in Raohe, Northeast China. To date, this reserve is still the only national nature reserve established in the whole of Asia to protect bee species, and it is not an exaggeration to say that the black bee is the giant panda of the bee world. ”

"So that's the case, it sounds like it...... "Xu Yi seems to understand whether he understands or not, but he only makes up his mind to find books to study by himself in the future, and he is embarrassed to ask more, after all, this Teacher Zhu is specialized in academic research, and it is really embarrassing to let people popularize science for themselves.

"The Northeast black bee likes to pick gum to make propolis, which is a characteristic of European bees, for example, the Chinese bees in our country do not collect gum at all. ”

"It seems that there are a lot of propolis products in the pharmacy. Xu Yi said that every time he goes to the pharmacy, he can see various brands of propolis products on the health care product counter, and it seems that the sales are also very good.

"It can be said that most of the propolis sold on the market is fake, especially the products sold online, and there is a flood of fakes. ”

"Why?"

"These bees don't normally collect gums, their main business is to collect honey, otherwise they wouldn't be called bees, they should be renamed rubber bees, this propolis is just used to repair and strengthen the nest. Xiao Xu, do you know how much honey a box of bees can collect in a year, and how much propolis can be collected?"

Xu Yi shook his head, "I don't know." ”

"If you don't rush to the field and don't harvest immature honey, a box of bees can pick 30 catties a year, and if you don't have propolis, a box of bees will generally produce no more than two taels a year!"

"So little?"

"Yes, the world's propolis production is only four or five hundred tons a year. ”

Speaking of this, Zhu Zhiwen asked Xu Yi: "Xiao Xu, do you know how much propolis our country sells in a year?"

"I don't know. ”

"Last year alone, the sales volume was almost 1,000 tons, if it is not adulterated, where does the extra propolis come from?"

"Could it be ......" Xu Yi suddenly understood, in recent years, even things such as peppercorns and chili noodles have been frequently exposed and faked, how can there be no counterfeiting of health care products with such a high price!

Zhu Zhiwen said indignantly: "Yes, this can only be achieved by counterfeiting, and those so-called pure propolis are often fakes doped with gum." ”

"Ironically, when this propolis is purified, it is necessary to remove the impurities of the gum and beeswax, and when the finished product is processed, it is necessary to add those gums that are not beneficial at all, and even add propolis to the gum or not add it at all, just call this propolis. Originally, I ate this for health care, but now, it's okay not to eat any problems!"

"Of course, if you have a patriotic slogan and say that your product is the propolis of the Chinese bee, it is an outright fake, and the Chinese bee does not even collect the gum, where can you get the real propolis! You can ask those who claim to raise native bees on the Internet whether there is any propolis at home, and if the answer is, then I can tell you with certainty that his family is definitely not soil honey! Because the Chinese bee does not collect propolis, where can I get you propolis!"

"Scrapers like this scraper, as well as these gel collectors that are placed in different parts of the beehive, are specifically used to scrape or induce bees to brew propolis in order to collect propolis. ”

Zhu Zhiwen pointed to a drawer-like wooden frame next to him and said with a glass plate inlaid under it: "This is the electric shock extractor used to extract bee venom, and when you use it, you can pull a layer of taut nylon cloth suspended above this glass plate, and then pull a metal electric shock wire on top of the nylon cloth, and put this thing at the door of the honeycomb, which can shock the worker bees, so that they will come and sting on the nylon net, and then discharge the bee poison on the glass plate." ”

"Doesn't the bee sting die all at once, and leave the bee sting in the flesh, doesn't that make the bee lose?"

Zhu Zhiwen took a roll of nylon cloth and said: "Don't worry, it won't cause too much loss to the bees, the worker bee tail needle will not be hung by this nylon net, wait for the detoxification, and you can pull out the tail needle, as long as the poison is taken, it will be fine if you feed it carefully for a few days, but it is best not to shock the new bee, the anti-electric shock ability is too poor, and it will be electrocuted." ”

"Like these little things, some are used to take pollen, some are used to produce royal jelly, and then there is a large number of relay boxes specially used to increase the honeycomb during the nectar period, and we really don't have a chance to use them here. Zhu Zhiwen said the same, and then explained the purpose to Xu Yi in detail.

"It's okay, it doesn't seem like a lot of money. Xu Yi saw that most of them were mainly wooden, so he didn't have to spend much money.

"Well, that's a good thing to say, and that's going to get to the big head. ”

Xu Yi pointed to the unexplained platform with a motor next to him and asked, "Are these?"

Zhu Zhiwen nodded, "Yes, the earliest beekeeping was made by bees themselves, and then beekeepers destroyed the spleen of the hive and collected honey. However, it is too time-consuming for bees to build a spleen, and sometimes they will transform a half-built nest into a male beehive. Nowadays, artificial nests are used, which can speed up the nesting speed of bees, and the built nest workers can build a very beautiful hive with a little modification, and can also control the number of drones that do not work without eating. ”

"Teacher Zhu, is this machine the foundation of the nest?"

"Yes, if it is a bee or a bee, it is good to say, there are many domestic breeding, the nest base is not expensive, buy a large number of them on the Internet, or even as long as a piece of anise can buy one, a small amount of breeding, there is no need to buy their own nest foundation machine, directly buy the nest foundation made by others, so that you can save money, of course, buy the nest foundation, beware of some bad businessmen will be mixed with too much paraffin wax, it looks bright and straight, but the bee does not like the nest at all, but does not build a nest. ”

"Can't you buy the nest foundation of the black bee, it's really not good, can't you buy the nest foundation of the seed bee or the nest of the Italian bee?"

"Really no, all kinds of bees are different in size, this black bee is larger than other species, so this nest can not be mixed, the black bee nest base is because of the small amount of feeding, so the ready-made nest base is difficult to buy, like the nest foundation of the bee is best to buy, even the aluminum nest base has, this is very durable, the bee's nest base also has a nylon nest foundation for sale, but the black bee is difficult to buy even the nest foundation, and we are a scientific research unit, sometimes need a special nest foundation, so we simply designed and customized this set of nest equipment, if you don't do your own nest foundation, then the bee spleen is broken, there is no way to repair and replace, you can only rely on worker bees to repair, it will be very slow。 ”

Zhu Zhiwen pointed to the machine and explained to Xu Yi: "This is a one-time forming nest foundation machine, which is suitable for use at an ambient temperature of 15 to 30 degrees. The front half is the tablet press, add the filtered liquid beeswax to it, and then set the automatic heating and heat preservation according to the ambient temperature, and the circulating water is cooled in the tablet roller, so that the wax liquid is cooled and condensed in the middle of the tablet roller, and the wax sheet can be continuously produced with a standard thickness。 ”

Zhu Zhiwen took out two sets of wrapped rollers from the drawer under the table and said: "The pressing rollers of this nest foundation machine can be replaced, and replacing this set of rollers with longer teeth can produce a deep nest base suitable for manufacturing insect spleen. This tablet press and nest machine are both aluminum alloy, and the specifications are calculated, which is the most suitable for Northeast Black Bee. ”

"Oh, that's expensive, isn't it?"
