Miss Fan, who was looking for beans in America a few days ago, shared photos of palm trees and big-billed bird estates. This is one of them, which we call compost from a planting point of view, which means that some unwanted biological waste in the manor, including coffee peel, waste branches, leaves, soil or some animal manure, is fermented over a period of time to form black soil. From the picture, we can see that there are earthworms in the soil.

It should be this time last year, a well-known coffee grower in Yunnan also posted a moments saying that he would no longer adhere to organic cultivation.

Organic farming is a production process certification with many requirements, including the non-use of fertilizers, pesticides and growth hormone. Why is it more difficult in coffee? For example, weeding, when the rainy season comes in May, coffee is growing, grass is also growing, glyphosate is used in one day, and the grass dies in a few days, while artificial weeding is expensive and slow, except that the grass is removed in half a month. Looking back, the grass in front grows again, and the grass in Yunnan grows two or three centimeters a day in the rainy season. For example, fertilizing, do you use compound fertilizer? When you put in the things used for coffee growth and put in the compound fertilizer, the tree will have all the nutrients it needs. Weeding and chemical fertilizer alone have determined whether there will be a harvest this year, and farmers are really waiting for this season's harvest.

Black soil, insects, earthworms or birds are seen in a growing environment. As long as the use of drugs, this series of ecology will be broken to varying degrees, so that the next link can not be supplemented.

Simple points, there are four ways of agricultural planting: 1, born to nurture, what is on the ground to collect what, 2. Planting, what fertilizer the crop needs; 3. Organic cultivation, the use of organic fertilizers, no pesticides; 4. Natural planting, Japan seems to be called friendly planting, all pesticides come from nature, such as insecticidal chili water, fertilizer from the compost of biological waste in a small environment, from nature and back to nature.

Coffee is slightly different, which is explained in several producing areas:

1. Ethiopian coffee, for example, is the result of a mixture of the first, second and third ways, and everything is a natural primitive agriculture.

two。 Artificial growing areas, such as Kenya, have selected SL28,SL32 from more than 40 types of coffee, which happens to be a bourbon and a tin pickup.

3. The American manor mentioned at the beginning is adjusted to a good planting environment.

Some estates in South America are in transition to the fourth way. Why should we make the transition to the fourth way? Flavor, things grown in the local soil have a local flavor, not just piled up with artificial chemical fertilizers, but by changing the way they are planted and making use of the limited natural resources available to form a system for the growth and prevention of boutique coffee. achieve the effect of a forest that can take decades or hundreds of years, but this forest is dominated by coffee trees.

Yunnan has a good growing environment, which is the opening words of many regrets for Yunnan coffee. But most of them don't know what is good about Yunnan. Its good refers to the environment suitable for coffee growth; it has altitude, slow growth and large temperature difference, which is conducive to the accumulation of coffee beans, which Hainan does not have; there are mountains in the north, the cold current in Siberia can not come down, and there is no frost, which is not available in Guangdong, Guangxi and Fujian. When the cold current comes in these provinces, the basic coffee will die; there are many mountains, so it is easy to form a small regional climate. These factors are the biggest reasons why Yunnan can still try to grow coffee outside the gold belt.

Now that you have the basics, let's talk about planting. There are three important time points for coffee to be planted in Yunnan. the first is to enter Yunnan with missionaries in 1902 after the opening of the Yunnan-Vietnam railway, and the second is to grow coffee for the Soviet Union's eldest brother. Cuba has been arranged to grow sugar, and there will be no more news if the relationship is not good. The third is to provide Nestl é with raw materials for foreign exchange in the context of rust. Knowing this period of history, we can see why Katim is the main variety. Although Yunnan, like Kenya, has a variety breeding process that is different from primitive agriculture, Kenya's breeding direction is to higher quality. Yunnan's breeding direction is disease resistance and high yield. Compared with Katim 7963, the old varieties Tippika and Bourbon are less resistant and high-yielding.

Katim is the main planting area in Yunnan, so when it comes to people in Yunnan's boutique coffee industry, it seems hard to talk about it. After all, no one dares to let farmers spend a few more years replanting varieties. Who should be held responsible if the consequences are bad? They have already mobilized farmers to plant Katim at a time when coffee raw materials are expensive. As for the performance of different varieties in Yunnan, Liu Minghui, who supplies beans to Starbucks at the Tropical crop Research Institute, seems to be trying. When Yunnan coffee is far from talking about varieties.

But it can't stop the take-off of Yunnan coffee beans. In the past two years, a new world has been discovered, that is, the method of treatment. If there are no good beans, you can use the method of treatment to form a flavor. Why didn't you think of it before? In this way, there is no need to talk about varieties, elevations, or new kinds of coffee. Treatment is a priority. In fact, the raw bean brand 90 + in the beginning of the treatment method, is based on the variety, altitude two conditions have been formed on the basis of the attempt. The priority treatment of Yunnan beans is the problem of beans with a score of 60 to 70, while paying attention to the altitude and variety, as well as the treatment method after the improvement of the planting method, is the problem of 80 to higher score.

Many of us come from the countryside, but in fact, most of us have no idea of fertile soil. We always use pesticides and chemical fertilizers to solve problems quickly. For farmers, it is really the best policy to bombard it with a gun barrel for half a year.

It is precisely for this reason that the soil in most areas has lost its vitality due to overdraft, resulting in the dilemma of hardening, lack of fertilizer, no growth without fertilization, and loss of fertilizer money as soon as fertilizer is applied. Yunnan fresh fruit coffee, the purchase price is about 1.2-1.5 a kilogram, only to pick labor, it is necessary to remove 1 yuan a kilogram. Even normal production can not be maintained, let alone ask them to invest more resources in variety selection, planting management, and adjustment of treatment methods. This is the endless cycle of Yunnan coffee.

Yunnan has always produced tea. There is a place called Iceland. The entrance of Icelandic tea smells like orchids. A tea tree can sell for almost 200000 at auction. Not far from the growth of the king of tea, there is also a tree of coffee. Depending on the year, it should have been planted at a high price and then cut down. The leaves are green and green. The soil there is a little black, and good things are inseparable from good soil.

Good Yunnan coffee beans, there will be. But we need to go back to the basic issues of land, variety and altitude, which is, of course, step by step. French red wine is also a flavor product, and they use a planting method called reasonable planting, which is the limited use of pesticides or fertilizers without excessive damage to the flavor, which seems to be more practical.

As for why there are still Yunnan beans with high scores after many varieties are separated from the soil above sea level, this should be a good question.
