In the cold and snowy north-east heating room, a tropical dragon nut is blooming like a flower of night; on the 28th floor of beijing, by the floating window, it's like a red lantern, and it's not a science fiction scene, but a "problem of the balcony" being performed in the northern family. The dragon nuts once thought to be grown only in the south are now breaking geographic limits and becoming the new pet of urban gardeners。
The memory of tropics' survival
The dragon nuts are cactus cactus, and have drought-resistant genes in their bones. A recent study by the horticulture department of the inner mongolia university of agriculture found that, when ambient temperatures were maintained at more than 15°c, the dragon root system was able to complete its entire life cycle in the plant environment. This means that a closed balcony with heating in the north can simulate the temperature differentials of the tropical day and night, and that winter hibernation is conducive to the accumulation of flower energy。
Aunt zhang of shanxi taihara broke the question with the facts: her six flaming dragon nuts have more than 50 results a year, and the secret trick is the "stand out." "the springing of winter in an unheated building, when spring moves back to the balcony, it's better to serve than more meat!" in the video, the branch that she's wearing with her hand is taking root in the yogurt box, and it's the strength of the dragon nuts that conquer the bottom of the north。
Sowing a living "dumb" lesson
Seed to forest
It is easier to get a red-heart flamingo, which is filtered in silk stockings 24 hours after the immersion of the meat, and black seed grains laid in wet tissues. Harbin's young man measured three days on a heater, 90 per cent of the seeds white spots and a higher rate of seeding than in the south。
The earth machine
Senior players recommend a "three-formula" formulation: three pine needles + three slag particles + three coconuts, with the remaining one salooning. Experts at the beijing botanical garden cautioned against the use of fields and soil, the water quality of the north being alkaline, and the need to water rice to regulate acidity once a month。

The seed sprouts are spread evenly over the ground, covering food seal boxes to create mini-cools. Tianjin has invented the "heating sprouts": put the seeding box on the router and keep it warm at 28°c, five days to see a green carpet。
I've got three tricks for the flower machine
1. Photometric control
Ms. Chang chun liu shared the view that in summer, strong light was filtered through a sun-covered network, winter light was irradiated for six hours per day and simulated tropical light rhythms. Her fiery fruit blooms three times a year, and it's 25 cm in diameter, and it's called "the balcony flower."。
2. The catalyst recipe
As the branch grew to 50 cm, the water was suspended for 10 days in order to create drought, which was followed by water and banana fermentation. In this way, mr. Aoshima succeeded in opening up a three-year-old plant with light milk。
3. Winter rule
Shenyang professional player's move: we lost weight and water in november, keeping the main branch to trim the sides. Packed with used sweaters, with double windows to stay warm, and 20°c will also be safe outside. When the stake wakes up in april of the next year, it will erupt。
A miracle of life
The 10-year-old boy in hebei completed a scientific experiment with a flamingo plant and recorded an outbreak of 15 cm per month for branches. When coral-like green branches crawl with a network of protection against piracy, when white flowers bloom in the middle of the night, this dialogue of life across latitudes is the most moving romance of urban farming。
At this moment, the empty flowerpot on your window is waiting for a tropical storm. Take the leftover flamingo out of the fridge and maybe next spring you'll harvest your own red dragon in the north. (tips: the north proposes to select cold-resistant red crystal varieties with a stable outcome of a plant for more than three years)
