China or the introduction of "biodynamic law" to see the moon "face" grape species

Jellyfish Net July 6 (YMG reporter Yu Yang) buried the horns stuffed with cow dung in the soil, and then took out the following year for fertilization, acupuncture for the soil, looking after grapes with the moon... you must think this is incredible. In fact, the growth of a vine has to undergo such a bizarre process. This method of using the "biodynamic method" to grow grapes has become popular in Europe and the United States. Yesterday, at a forum on grape planting technology, Zhan Jixi, an associate professor and doctoral tutor of China Agricultural University, said that his team is preparing to introduce such a planting method into China for experimental research.

Fertilizers are sophisticated. Novel formula grape

"Biological dynamic method", it is hard to understand the mysticism by listening to the name, but if you say "organic cultivation", you may understand. "The two have the same place, but they are not the same." According to Zhan Jixi, similar to organic cultivation, the biodynamic method also advocates the use of no synthetic chemical fertilizers, pesticides, growth regulators, etc. Natural respect, to the greatest extent possible to maintain the sustainability of the planting environment. "The difference is that the biodynamic law more emphasis on coordination with the astrology, according to the relationship between the earth and the moon to determine the time of planting, fertilizing and harvesting, which also Religion, art and other aspects are related.

It's no surprise that cow dung is used as a fertilizer to grow plants. But it's strange to put it in horns and then bury it in the soil and fertilize it. "Put the organic cow dung into the horns, bury it in the vineyard soil in the fall, wait until the spring, and then take out the fermented fertilizer from the horns, mix it, dilute it with rain, and spray it on the vineyard." This is a legend in Burgundy. Winery Le Huan is a winery that uses the biodynamic method to grow grapes.

Zhan Jiyi explained that this method of fertilization can be understood as the production of organic matter, minerals, etc., after the fermentation of the crops, so that the soil is more nutritious. However, there is no clear basis for the use of horns. However, Rudolph, the founder of the Biodynamics Law, has proposed using only a single horn to produce fertilizer. There are not many real estates that are used in this way.

A moon cultivates plants and determines drinking time

In biological control and livestock use, the manor uses ladybugs to remove locusts, sheep and cattle to remove weeds, and chickens and ducks to defend against pests. The animal's excrement can be used just as fertilizer. In intercropping, the biodynamic method of the estate will plant spicy or firey plants to balance the water-based grapes, "will also plant special grasses to control the growth of grapes."

In the process of grape growth, the relationship between the moon and the earth is considered as an important planting basis. Europeans believe that the growth of the vine is affected by the constellation, and therefore the wine will be affected by the universe.

Some researchers believe that this is similar to the Chinese lunar calendar and the Chinese calendar. Just like the older generation of fruit growers will also do farming based on the phases of the moon, such as avoiding pruning at the full moon to avoid damaging the vigor of the grapes; and the farmers will find that the wine is rather turbid at the full moon and is not suitable for bottling. Change barrels at this time; during the period between the new moon and the full moon, it is considered the best period for grape growth, suitable for grafting or planting.

Not only is planting, even drinking is stipulated. At present, some supermarkets in the United Kingdom have formulated drinking schedules based on this "biological dynamic calendar."

The scientific community questioned the planting method, but the taster actually stood up

Zhan Jixi tells that as early as 1996, in a vineyard in California, scientists began an experiment on soil fertility. However, in six years, no change in the quality of the soil was detected. Even leaf tissue, grapevines and berries were analyzed and there was no difference. Since then, the scientific research community has continuously questioned the effectiveness of biodynamics.

Some researchers even directly questioned that “those who bury their horns at the moon are just gimmicks. The possible explanation is that the biodynamic method is forcing growers to spend more time and energy in the vineyard, which of course will affect the grape fields. "It helps." Zeng Ji, who has been to Europe for the investigation of biodynamics, said that in Europe, wines produced using biodynamic methods are still recognized in the wine industry, which is in stark contrast to scientific experiments.

In spite of this, according to the statistics of the Biodynamic Sports League, more than 5,000 manufacturers and 150,000 hectares of wine parks have adopted biodynamic methods in 45 countries.

"We are ready to conduct experiments in China and find a site to study whether the biodynamic method has an effect," said Zhan Jixi.
