A powerful country in scientific research

Hearing this, Jiang Hongmei pushed the door and entered the office. Since there were only her and Yang Qingshan in the room, Jiang Hongmei did not close the door.

Looking at Yang Qingshan who was sitting at his desk, Jiang Hongmei smiled and said, "Director Yang, it worked. It's been ten days and there's nothing wrong with the mushroom sauce."

Yang Qingshan smiled when he heard this, "Bring it here for me to see."

Jiang Hongmei quickly handed over the things in her hand, "Director Yang, it's been ten days and the mushroom sauce hasn't changed at all. It seems that the shelf life in a vacuum state is indeed very long. Our factory can try to produce this small portion of mushroom sauce."

When Jiang Hongmei just returned to Haishi, she sent the drawings of the plastic vacuum packaging machine to Engineer Wang of the machinery factory. A few days after she sent it, the machinery factory finished the machine and sent it to Director Yang. Jiang Hongmei took the machine to find Director Yang and talked about the advantages of vacuum packaging and the benefits of producing small portions of mushroom sauce. Director Yang was very excited. With small portions of mushroom sauce, families with poor conditions could also afford it. However, he was excited, but he still wanted to see with his own eyes whether vacuum packaging was really that good. So Jiang Hongmei got a few packs of vacuum-packed mushroom sauce to see how long the mushroom sauce could be stored.

Yang Qingshan looked excitedly at the mushroom sauce in the transparent packaging bag in front of him, which looked exactly the same as it had just been produced. He tore open the bag, and the aroma of the mushrooms immediately wafted out, still that familiar scent.

Yang Qingshan raised his head excitedly, "As expected of Su Ran, everything she researches is good!"

Hearing this, Jiang Hongmei's face was full of smiles. She also thought that her daughter was very outstanding.

Yang Qingshan: "Su Ran has been in the countryside for half a year, right? When will she come back? Any news?"

"Well, he just called me yesterday and said he would be back in a while."

Yang Qingshan would laugh out loud, "Okay, okay, when that girl comes back, maybe she can bring some good things to our factory."

Jiang Hongmei's smile got bigger. "Maybe. No matter if she can bring new things or not, as long as she can come back, I'll be happy."

Yang Qingshan suppressed his excitement and said, "Yes, as parents, we feel more at ease when our children are around. Director Jiang, please sit here for a while. I will ask Secretary Liu to call Deputy Director Wang and a few others over. We will have a small meeting. Then you can tell us in detail the cost and related expenses of this plastic vacuum packaging machine. If it is feasible, we will produce a batch first."

Jiang Hongmei nodded, "Okay."

......

The atmosphere in the meeting room was tense, and several factory managers had serious faces and frowns.

Jiang Hongmei stood on the podium and said confidently: "I think if we can produce small packages of mushroom sauce, we will definitely be able to increase sales. Now more and more people like convenient and fast food, and we can't fall behind."

Jiang Hongmei's words made several factory managers feel moved, but they did not make a decision immediately. They still thought rationally about the feasibility of this matter.

Deputy Factory Director Wang questioned, "The product is good, but the cost is still a bit high. Considering our factory's shipment volume, we need at least 20 machines. The machines alone cost a lot of money, and the plastic is also a cost. If no one buys it after it's made, won't it be a waste of money?"

Jiang Hongmei patiently explained: "Deputy Director Wang, we can try selling it for a while. We can use this machine to produce some and put them in the department store. If the effect is good, we can continue to purchase more machines. If not, then we can just end it here. We won't lose much. But having said that, I am still quite confident about this. With this vacuum packaging machine, not only mushroom sauce, but also our previous canned meat can actually be packaged with this machine. The cost can be much lower. With a lower cost, our selling price can also be lower."

Deputy Factory Director Liu frowned. "The sales volume is very good at this price now. Why do you have to lower the price?"

Jiang Hongmei: "Deputy Director Liu, we are not really reducing the price. We are producing two products. The price of glass jars remains the same. We will also produce some plastic vacuum packaging, which is smaller in weight and cheaper in price. This is aimed at families with poorer conditions or people who travel frequently. Plastic packaging is easier to carry than glass bottles."

After hearing her words, several factory managers were silent for a while, and then began to discuss. After a heated debate, the factory managers were finally convinced by Jiang Hongmei's point of view, reached a consensus, and agreed to start producing small packages of mushroom sauce.

After the meeting, several deputy factory directors left one after another. Jiang Hongmei sat in her seat and took a deep breath. Fortunately, she did not disappoint her daughter's expectations of her.

Since the factory has decided to use the plastic vacuum packaging machine, can she develop some other products... Just like the roast duck that He Cheng brought over during the Chinese New Year, she can also make some of this kind of things. With a plastic vacuum packaging machine, the shelf life of the product can be extended. When it is ready, it can be packaged with a vacuum packaging machine, and the roast duck can be stored for a longer time... Isn't this a perfect business opportunity!

After coming up with the idea, Jiang Hongmei changed her previous dejected look, stood up excitedly and walked towards the office.

So, Jiang Hongmei, who had a new idea, became busy again.

Su Ran from Qinghe Brigade has been very busy these days. In the morning, she trained Zhang Xue and Li Yun on greenhouse-related knowledge and skills, and answered their questions. In the afternoon and evening, she devoted herself to drawing the blueprints of the color TV, carefully outlining every component and detail, and constantly modifying and adjusting until the final result was perfect.

Although the work is busy, he enjoys it.

For example, at this moment, looking at Zhang Xue's excited expression, Su Ran couldn't help but raise the corners of his lips.

"Ranran, I feel like I've almost mastered it. Can you test me?" Zhang Xue said excitedly.

Li Yun standing beside him was also eager to try.

Su Ran's smile widened, and she nodded, "Okay. Then I'll test you, starting with Sister Zhang Xue~ Sister Zhang Xue, if the leaves of the green leafy vegetables in the greenhouse turn yellow, why is that?"

Zhang Xue: "Nitrogen deficiency, iron deficiency, magnesium deficiency, and zinc deficiency may all cause the leaves to turn yellow. Inappropriate soil pH or pests and diseases may also cause the leaves to turn yellow and develop disease."

Su Ran continued to ask: "Then how do we determine the specific reason?"

"Nitrogen-deficient leaves usually appear yellow-green, and the lower part of the leaf is more obvious than the upper part. The leaf is smaller and the petiole is slender. Magnesium-deficient leaves will appear yellow or faded green, but usually in the middle of the leaf, and older leaves are more likely to have this situation. Iron-deficient leaves usually appear yellow-green or light yellow, but the veins and petioles remain green. Based on the characteristics of leaf color, position and shape, we can preliminarily judge which nutrient the plant lacks."

Su Ran curved his lips and continued to ask, "When it rains heavily in the summer, the rainwater on the shed collects at the 'front' of the shed and has nowhere to flow. For several days in a row, no one can go in. There is even a phenomenon that the front edge of the shed is washed away. Why is this? How can it be solved?"
