The farmer said that he began planting cabbage in autumn. After the autumn season, just after the village of Guozhuang, Yangsong Town, Huairou District, the young cabbage seedlings in the fields have already emerged. These are not ordinary cabbages. They are four kinds of old Chinese cabbages that the city has tried to plant this year: Xiaoqingkou, Daqingkou walnut pattern, Baotouqing and Yuyuantan walnut pattern. After the successful trial, the old taste cabbage will return to the citizen's table.
When I walked into the experimental site, I looked ahead and looked at a large area of ​​new ridges. On the top of the ridges, a small green shoot emerged from the top of the earth. The staff of the seed management station of the Agriculture Bureau of Huairou District introduced a total of 8 acres of land in this large area and planted 6 varieties of cabbage. In addition to the old taste cabbages of four trial species, there are two control varieties: Beijing New 3 and Jingqiu 4. Old taste Chinese cabbage can not return to the people's table, but also have to look at the taste, disease resistance and other aspects can overcome these two widely cultivated varieties.
The four old varieties that were planted in this experiment were all sourced from the Variety Department of the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences. They are all local varieties in the Beijing suburbs and have a long history of planting. They have long been the masters of the table in Beijing. dish.
Why should we try these old Chinese cabbages? Originally, old-style Chinese cabbage had the disadvantages of low yield, poor disease resistance, and large field management workload. Since the 1960s and 70s of last century, in order to increase the output of vegetables, the city has successively improved and improved the local dishes, resulting in a large number of new varieties. . However, after the output has been raised, cabbage no longer tastes the same. In recent years, Beijing's suburb agriculture has embarked on a development path of quality development. It is no longer simply pursuing production but also pursuing quality. As a result, the authentic old cabbage variety will return to people's perspective.
“The four kinds of old taste cabbages that were planted this year were selected after several trials. At first we found a total of 12 resources, including 6 varieties, some of which were from the Academy of Agricultural Sciences and some from Fengtai. After several rounds of planting, the old vegetable farmers found out that some of the well-behaved plants were eliminated and some of them performed well. "said Chi Xiulong, head of the seed division of the Beijing Seed Management Station. This year, the city is in Changping, The three bases of Shunyi and Huairou have been expanded to try to plant 4 old varieties, which is to continue to “purify and rejuvenate†these well-performed varieties so that they can be promoted in the suburbs in the later period.
The varieties are still those varieties, but it is not easy to grow 40 years ago under today's natural conditions. The staff of Huairou District Agricultural Bureau Seed Management Station introduced that it must be planted under the most suitable season and the most suitable environmental conditions. Soil, light, temperature and other conditions must not be sloppy; when planting, high quality, decomposed organic fertilizer should be used. Coupled with balanced fertilization and application of biological bacterial fertilizers, biological pesticides are used to prevent and control pests and diseases; scientific management methods are used during the growth period to finely pulverize the fine tubes; finally, they are harvested during the best harvesting period. "We are more concerned about the characteristics of this species can not be fully displayed, Xiaoqingkou looked like Xiaoqingkou, the output fell to the next." Staff said.
Because it is a test field, scientific observations and records must be made throughout the entire period. In particular, when harvesting, the height, radius, leaf color, etc. must be measured, and cabbages of different varieties must be cut in half to observe the color and radius of the cabbage. Plant height, compactness and other indicators. Through the comprehensive comparison of the observed data, it will be concluded that the old varieties of Chinese cabbage and new varieties of Chinese cabbage are superior to inferior, and ultimately determine which old varieties can be promoted in the suburbs of Beijing. “These varieties of Chinese cabbage are about 15,000 pounds per mu. By the fall of this year, some citizens will be able to take early tastes,†the staff told reporters.
It is understood that, in addition to Chinese cabbage, the city's agricultural department is still on the tomatoes, radishes and other common people on the table for the old varieties of species, try to get more old taste back to the people on the table.
