Microsoft co-founder Bill Gates recently called for the United States and other wealthy countries to abandon beef in a recent interview with MIT Technology Review magazine. "I really think all rich countries should switch to 100 percent synthetic beef," Gates said. ”

The British "Daily Mail" said on the 16th that in order to combat climate change and reduce greenhouse gas emissions, Gates believes that it is very important not to eat beef. Cattle and other ruminants produce large amounts of methane when they digest grass. According to the U.S. environmental agency, ruminants account for about 28% of man-made methane emissions each year.

Methane is a powerful greenhouse gas that absorbs 28 times more heat than carbon dioxide. Researchers believe that by the end of the century, global warming could lead to an increase in temperature of 4 degrees Celsius, which would lead to catastrophic consequences. But all sectors of society did not buy Gates's remarks.

There are 10,000 people in the U.S. who work in the beef cattle production industry, and not eating beef would cause mass unemployment. Some netizens think that Gates' words and deeds are inconsistent, and Gates previously said that he would still eat burgers made of real meat. Some netizens commented that Gates has enough financial resources to choose what to eat, but the high cost of artificial meat will put financial pressure on the public.

The purpose is to find out whether hydroponic radishes grow or not.

The step is to cut the carrot flat from 3 cm from the top, place it in the water without exceeding the top, and place it in a ventilated place. Wait for two or three days for the carrots to sprout, and don't bask in the sun during this time. Pay attention to changing the water during the period to avoid carrot rotting.

After a while, hydroponic carrots turn into cute little potted plants.

Hydroponic carrots can't produce turnips, the carrots we eat are actually rhizomes, and our hydroponic carrots are actually rhizomes, even if they take root, they are just rhizomes taking root, and it can't be said that they produce another carrot. Even if it is planted in the ground, it will not grow carrots, because carrots are biennial herbs, and after they have grown rhizomes, they will grow leaves, but the final result will be flowering and seeds, and they will not continue to pick up carrots.

4.Temperature and humidity management radish seeds can germinate in 2-3, and germination temperature is 20-25. The seedlings can tolerate low temperature of -2--3 and high temperature of 25, 5-25 can grow better, and the growth temperature is 15-20.

If the temperature is too high, radish seedlings are easy to rot, and if the temperature is too low, radish seedlings grow slowly or even stop growing. The goal of temperature management is to control the ambient temperature within the range of 15-20 for the growth of radish seedlings, and not beyond the range of 5-25. In winter, the temperature is raised by heating and insulation equipment, and in summer, the temperature is lowered by ventilation and shading.

Radish seedlings are prone to mildew and rot in the case of high humidity (especially in the high temperature season), so the humidity of the growing environment needs to be controlled below 70, mainly by strengthening ventilation to reduce the humidity. 5.Water management water is poured twice a day after sowing, and once in case of rain and snow, it can be watered once as appropriate.

The cotyledons immediately peel off the paper that covers the upper layer. After the plant height is 3 cm, start pouring the nutrient solution. If you use aged seeds for hydroponics, it is particularly important to water the nutrient solution in the later stage, otherwise the radish seedlings will grow slowly and will be easy to rot.

The simple recipe for the nutrient solution is: a bucket of water (15 liters) plus 5 grams of urea and 7 grams of potassium dihydrogen phosphate. 6.

The cotyledons are fully harvested, and they are harvested in time when the real leaves just emerge, and they are easy to rot when they expire. In general, hydroponic radish seedlings are on a whole plate**, and the roots are cut off when eating.
