Chen Xingzong / Sister Fang's tea garden miracle, using less fertilizer and no pesticide, the topsoil organic matter jumped to 5% after 5 years.

Agriculture is a high-tech industry, but it is a pity that universal recognition makes its output value not high, so it falls into a vicious circle, and everyone also bears the bitter consequences. I have written this article to share with you the power of nature I have seen and the beauty of pragmatic agricultural science and technology.

This is a tea garden at the southwest end of the Pingdingpu platform in Zhushan, covering an area of 0.45 hectares and only more than 150 meters above sea level. In recent days of heavy rain, crops in almost most of Taiwan's farmland and tea gardens have suffered badly, but the more Rain Water is dumped, the healthier the tea garden will become.

Abnormal sudden rain continues to accumulate, but the lower the rain, the better the tea. Low maintenance with no medicine and less fertilizer, thick tea buds and amazing quality

The altitude here is not high, but the quality of tea is quite amazing. Green tea, oolong tea and black tea are made of green tea, oolong tea and black tea. Only the relatives and friends of Sister Fang have a taste of green tea, oolong tea and black tea.

Due to the difficulty of the former owner's management and dissatisfaction with the profit, Fang Jie and her husband accepted the purchase of the tea garden by chance. At that time, I also knew Sister Fang and her family because of the management consulting needs of this land.

In the first two years after taking over, the output and quality of the tea garden were not very ideal, but Sister Fang persisted in managing the tea garden with correct management.

The so-called "correct management as" is also guilty. At the beginning, according to the principle that Sister Fang's family expected to use less medicine and less fertilizer, I put forward a low-level maintenance and management act in line with the principle. Because the host also continues to have confidence in me, full and honest cooperation. In the third year, the tea garden began to make a positive improvement, and the local neighbors also witnessed the change of the tea garden.

At the initial stage of system recovery after 103 years, there was almost no harvest. Winter tea dry tea 17 jin in 103. 104 ─ has been harvested once or twice a year since 106 years. In 107, it has reached three harvests a year, and the output is close to 50% of the tea garden used to be nearby.

The more it rains, the more beautiful the tea becomes. Weeds and organisms are diverse, but tea trees are healthier to manage easily.

The most interesting thing is that Mr. Wu (who used to be a veteran tea farmer in the neighboring greenhouse) will tell me every time he sees me. He always said, "I really don't understand what this tea garden is doing." I didn't see her fertilize and spray, how can the tea tree be so healthy? Is it easier than his previous management experience? What on earth happened? " . And often ask me what elixir I gave her.

This tea garden often surprises me. I like to observe and learn from this tea garden, to see how it has changed under the low degree of interference and meticulous management of Sister Fang's family.

Sister Fang seldom fertilizes and even saves the symptomatic foliar fertilization that I usually use. Because even without fertilization, they grow very energetically and do not show any symptoms of element deficiency, only because in order to increase the content of theanine, I agree to apply some soybean powder before the sprouting of winter tea every year, each part of the land is less than 100 kilograms.

No medicine at all, insects are active, but the harm to tea trees is limited.

Although there is a sprinkler irrigation system in the park, ants often build nests and plug pipes, and sprinkler irrigation has become a nightmare, and it is still plugged several times, so Fang Jie simply does not spray irrigation has become the norm, only to see that rain is the main force of irrigation.

Weeds in the park are relatively often managed, and I suggest that we do not have to be too active, but we should try our best to eradicate them. Now the weeds in the park are diversified, as long as they are no higher than 70% of the height of the tea tree.

Sister Fang does not apply medicine at all, but she has never complained about diseases and insect pests. Without pesticide application, only the tea buds near the edge of the bamboo forest were seriously disturbed, and the damage of small green leafhopper and leaf anthracnose was tolerable in the rest of the region. What is interesting is that there are flower spiders, military planthoppers, brown moth wax cicadas, green moth wax cicadas, fly tigers, dragonflies, ladybugs and lacewings in the region. There are more unknown insects that are very active, which I rarely see in other tea gardens.

The biological soil of diversified active tea garden was greatly improved, and the content of organic matter in topsoil increased significantly to 5%.

There are more magical things going on in the underground soil of this tea garden. At the first diagnosis in 103, the organic matter in the tea garden was concentrated in the range of 0: 15 cm in the topsoil, with a content of 1: 2%. The soil below 15 centimeters is rigid and unstructured.

Now, at least 40 centimeters of well-structured soil, ventilation and drainage is not a problem.

In the spring of 108, the topsoil of the tea garden contained 5% organic matter in the range of 0: 15 cm. The following 15 centimeters and 60 centimeters are also 21 percent. In conventional calculation, the topsoil at a depth of 15 centimeters per centimeter weighs 200000 kilograms. Suppose you want to increase organic matter by 1%, you need to put in at least 2000 kilograms of organic matter. On the other hand, the soil of 060 centimeters in a plot of land increased by 16000 kilograms of organic matter in five years.

In fact, only 2500 kilograms of rotten compost was lost in 103. The difference of organic matter content at two time points is 13500 kg. What's going on here?

Now, at least 40 centimeters of well-structured soil, ventilation and drainage is not a problem.
