"You know Liu Xueming, too. I don't know how many times I have traveled to Huangping Town! Let him introduce the situation of the experiment to you!" After saying hello, Professor Ju waved to his students and asked him to introduce them.

"Director Ran, Master Jin, I will introduce you to the fertilizers needed at different stages of the tea planting process first." Liu Xueming didn't have to read the record book, so he opened his mouth and introduced it.

"If you want to grow good tea, nutrition must be rooted. Generally, for every 100 kilograms of fresh tea produced, you need to absorb 1.2 to 1.4 kilograms of nitrogen, 0.2 to 0.28 kilograms of phosphorus, 0.43 to 0.75 kilograms of potassium, and tea trees like ammonium, polyaluminum, low chlorine and calcium. Fertilization should be mainly organic fertilizer and supplemented by inorganic fertilizer."

"According to Professor Ju's years of research, a five-step method is proposed to promote the growth of tea trees, tea quality and yield of tea."

"The first step: apply enough winter fertilizer. From October to November, combined with the deep cultivation of tea gardens, the base fertilizer we use is mainly composed of these raw materials, 30% of organic matter, 1.5% of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, six% of amino acids, four% of humic acid, 12% of calcium, silicon, magnesium and other minerals, and finally a trace amount of beneficial bacteria."

"This kind of compound fertilizer can provide sufficient nutrients for the growth of tea trees. First, lay a solid foundation for the tea trees to reduce pests and diseases and promote growth."

"The second step: apply germination fertilizer in early spring. One month before spring tea mining, apply spring bud fertilizer in time, use our own high tower sulfur-based tea special fertilizer, and apply it in combination with the weeding and weeding of the tea garden. After use, the tea spores can grow and produce more tea."

"The third step: apply sprouting fertilizer after spring tea is picked. Apply summer sprouting fertilizer in time after spring tea is picked. Also use special fertilizer for high tower sulfur-based tea, combined with weeding and applying it in the tea garden; it is conducive to harvesting the second wave of tea!"

"Step 4: Apply bud-promoting fertilizer before picking autumn tea, which is later than spring tea and summer tea. 15-20 days before picking autumn tea, continue to apply autumn bud-promoting fertilizer, or use high tower sulfur-based tea special fertilizer, and also apply it in combination with weeding and weeding in the tea garden."

"Finally, when conditions permit, in order to improve the quality and yield of tea, reduce pests and diseases and degrade pesticide residues, microbial bacteria agents can be mixed with water to spray both sides of the leaves, and used 3-5 times in a row, mainly in the four stages of spring, summer, autumn and winter clearing of the tea tree."

"Of course, the last link is quite complicated and requires a lot of manpower and material resources. It is a bit unprofitable to use it on ordinary tea, so it is only suitable for high-end tea at the moment!"

"Three hundred and sixty professions, every profession has its own tricks. I didn't expect that growing tea is more complicated than growing crops!" Ran Jiang had seen how they planted tea, but he still felt that it was nothing. Master Jin was stunned when he heard it.

"So, judging from what Senior Liu said just now, both base fertilizer and Gaota sulfur-based tea special fertilizer seem to be able to be industrialized!" Ran Jiang said.

"Although the base fertilizer is only used once a year, it is used in large quantities, which costs hundreds of kilograms per acre of land. Although the profit is a little thin, as long as the sales volume increases, you can still make money." Tea has a relatively large demand for fertilizer. According to what Liu Xueming just said, the demand for base fertilizer per acre is about 40 to 60 kilograms.

In addition, hundreds of kilograms of farm fertilizer must be added to ensure that the tea trees have sufficient nutritional supplements; take the average, just use fifty kilograms per acre of land, and then twenty acres are one ton.

In a province in Tiannan alone, the tea planting area exceeds one million mu. Only 20% is needed, which is 10,000 tons of annual demand, which is enough for Wendong County chemical plant to eat.

Moreover, Wu's Group has tea gardens all over the country. If you directly decide to cooperate with them, you can spread the products across the country in the shortest time. After the Wu's Group's tea garden uses the base fertilizer produced by Ranjiang and others, you will definitely come to buy the tea gardens around you, so you don't have to worry about sales.

"If the amount of sprouting fertilizer is not large every time, it will be used three times a year, which is not a small amount. Moreover, the time of use is just as staggered with the base fertilizer. We can adjust the production plan according to the season and provide tea farmers with sufficient fertilizer in a timely manner!"

Ran Jiang has already planned that the autumn tea picking season in Tiannan Province will end at the end of September. If you want to reverse the autumn tea germination fertilizer, it will start to be used in early September, while the base fertilizer will start to be used in October.

In this way, the production of autumn tea germination fertilizer can be completed before July, and then the base fertilizer can be produced with all its strength. In 7, 8, 94 months, sufficient base fertilizer can be produced for tea farmers to use in October and November; the remaining time will slow down slightly to produce germination fertilizer.

In the middle, we can make time to produce fertilizers for Agaricus bisporus, so that there are business to do in the chemical factory and products to sell throughout the year.

"Is all teas possible with fertilizers you developed, or is this fertilizer specially developed for Huangping Gong Tea?" Ran Jiang asked.

"The vast majority of teas can use these two fertilizers, which has a strong scope of application; of course, we have also equipped some special fertilizers for the characteristics of Huangping Gong Tea, but these are used in small quantities and are not included in these fertilizers."

"Before this, we actually used similar fertilizers in other tea gardens, and the effect was also good!" Liu Xueming stretched out his hand and pointed, "Look, there are actually several types of tea trees in our experimental field, all of which are used in this fertilizer, and the growth and budding rate of tea trees have significantly improved."

Liu Xueming's words made Ran Jiang and Master Jin feel relieved. They followed the path and looked over the tea garden. They saw that several different types of tea trees were growing very energetic, and the budding rate seemed to be higher than that of other tea gardens.

"From the technical aspects of the laboratory, after improvement, both formulas have become more mature, but whether similar results can be achieved after industrial production depends on your own!" Professor Ju added.

My mission has been completed, and it depends on your own whether you can do it well!

After the visit, Ran Jiang and Professor Ju obtained the formula and samples of these two fertilizers as agreed in the previous contract.

Then Ran Jiang took the information to register the patent. According to the contract, Professor Ju can enjoy the right to sign the patent, while the patent owner is the Wendong County Chemical Factory where the money is paid.

This time, Ran Jiang became familiar with the story. After submitting the information, he also talked with the old acquaintance about the progress of applying for the USB flash drive international patent.

After the end, Ran Jiang did not go back, and he still wanted to register a brand trademark.
