In the early winter season, the minimum temperature in Beijing has dropped to freezing point. Even the anti-freeze radish and cabbage have been harvested, but it is still green in the vegetable fields of the Yongshengyuan vegetable growing base in Xijia Village, Xijia Village, Tongzhou District. This year, Apollo Green, a new cold-tolerant lettuce variety introduced from Europe by the city's leafy vegetable innovation team, was first planted in the city, enriching the “food basket†of the citizens of the capital. It is understood that in the past five years, the team has focused on five kinds of leafy vegetables such as lettuce, celery, fast food, rapeseed and spinach, and has developed key technologies for breeding and breeding of vegetables, cultivation and facilities, pest control, and safety and processing of agricultural products. , Internet + vegetable industry key technology research and application promotion demonstration work. Among them, 34 new varieties of leaf vegetables were selected, including 7 fast-growing varieties, 10 rapeseed varieties, 8 loose-leaved lettuce varieties, 4 headed lettuce varieties, 2 celery varieties and 3 spinach varieties. It is worth mentioning that the selected rapeseed, lettuce and fast food are at the leading level in China, especially the “Jingyan Purple Fast Food†is the first purple fast food variety in the country; the three spinach varieties selected have solved the spinach The problem of convulsions, cold tolerance and poor adaptability greatly shortens the growth cycle, and the product tastes lighter, delicate and refreshing, and has good commercial properties; the selected celery varieties break through the summer cultivation difficulties and fill the market gap of summer celery supply. According to Cao Zhifu, a team expert in Yecao Innovation Team, the cold-tolerant vegetable varieties selected by the team include 25 varieties including Beisheng No. 4, Nongda Spinach No. 1, Jinglu No. 2, Pink Lotus No. 1, and New Purple Crown. Among them, the harvesting period of Apollo green lettuce in Beijing for the first time “settle down†can be delayed by half a month compared with ordinary open field vegetables, and the yield per acre can reach 2 tons, which is about 30% higher than that of ordinary loose leaf lettuce. The leafy vegetables that have been selected and promoted have also carried out four water-saving cultivation techniques. The average water saving per mu is 52 cubic meters and the fertilizer is 4.8 kilograms, which is a good driving effect on achieving zero growth of fertilizer. At the same time, the team explored 5 kinds of main planting leafy vegetables to develop more than 10 high-efficiency planting mouthwash combinations, established 7 sets of high-yield and high-quality cultivation technology models, developed 11 new cultivation techniques, integrated technology integration, and promoted and applied in 6 districts. The mu income reached 32,000 yuan, and the mu income increased by 35%. Disclaimer: Some articles on this website are transferred from the Internet.
