It is said that the current US president and his wife and the Queen have this hobby, often in person at the White House, Buckingham Palace garden spade dancing yet. In the Netherlands, Germany, USA, Japan, Taiwan and other places, the city's agricultural production has been quite widespread and well developed. Meng Yi City, Jiangsu Agricultural Development Co., Ltd. for your roof vegetables breakdown of benefits: reducing the burden for the country. China has over a billion people, China's grain supply and reserve must get their own, this is a strategic issue involving national security. In recent years, with increasing urbanization, arable land and declining agricultural population, food security has attracted the attention of the government and people of insight. At present, China is using only 10% of the world's arable land to feed 20 percent of the world's population. In order to increase food production, China's annual consumption accounts for 40 percent of world fertilizer and pesticides. High fertilizer to compensate for cropland - population ratio is low is really good problem-solving approach it? Clearly not. I am afraid that scientific cultivation is benevolent. Also, if you can spare the city residents, scattered indoor and outdoor space components utilized, in his spare time yourself growing vegetables, fruits, grain production is bound to reduce the burden of making no small contribution.

Tests showed that green leafy vegetables stored for 24 hours in a closed environment of 30 ℃, the vitamin C almost wiped out, and the nitrite content of harmful substances has increased several times. Nitrate in vegetables contain a chemical reaction with the enzymes and bacteria will produce nitrite, which in the human body and protein substances combine to generate strong carcinogenic nitrites substances. Nitrates in vegetables, mainly from fertilizers. Farmers in order to improve the yield and growth rate, often excessive, solely nitrogen fertilizer, or pick still need to pay before fertilization, too late to plant them all for the synthesis of nutrients, it will remain in the form of nitrates in vegetables and become a threat to health risks. Nutrient-rich green leafy vegetables nitrate content than the root class, higher solanaceous vegetables. If the vegetables in their own balcony, a cash eat, both fresh and nutritious, and health and hygiene. Sunlight, ultraviolet rays, reducing air conditioning load, energy conservation, the protection of the roof. Summer vegetables roof room much cooler than the room did not grow vegetables, winter vegetables roof of the room not much warmer than the room to grow vegetables, natural air conditioning load much lower, can be described as cool. Roof vegetable absorption, distribution of heat, which reduces the temperature difference between the surface of the roof and down to prevent floor cracks due to thermal expansion and contraction, but also block UV rays, protect the roof, extend roof life. Reduce pollution and improve the living environment.
