The first successful introduction of special corn in Zhenjiang City, Jiangsu Province

Thanks to the efforts of the science and technology department of Zhenjiang City, Jiangsu Province, special corn with unique flavor, rich nutrition, and convenient and affordable introduction has achieved initial success in some rural areas of the city. The Dinggang Town of Dantu District has introduced more than 10 glutinous maize varieties one after another. This year, with the help of the science and technology department, it has successfully introduced “Nongda Chaotian No. 1”. The total planting area exceeds 1,000 acres, and the products enter the wholesale market in Wuxi and become Drive new prosperity for local farmers.
Special corn mainly refers to sweet corn, waxy corn, high lysine corn, popcorn, high oil corn, bamboo shoots and corn. These corns have their own intrinsic heredity, and they have unique characteristics such as grain structure, nutrient composition, processing quality, and food flavor, and their respective uses and processing requirements are also different.
Sweet corn has the "four-in-one" use value of vegetables, fruits, food, and feed. In the milk ripening stage, the ear of green fruit is harvested. The peel is soft and delicious. It can be used for cooking, steaming, roasting, or by steaming and quick-frozen storage. Green or fresh fruit or grains can also be processed into pasty, granular or segmented canned foods, which can be used as quick-frozen sweet corn (grain), dried sweet corn, fried sweet corn, and fast food porridge. The tender ear of the harvested female corn silk that has not yet been exposed can be processed into canned corn and it is a new high-grade vegetable. The sweet corn stems and leaves have a sugar content of 10%-12%, a carbohydrate content of more than 30%, a protein content of about 2%, a fat content of 0.5%-1.0%, a tender and juicy, soft and sweet, Rich in nutrition, it is a good feed for the development of livestock and poultry industry.
Waxy corn is rich in nutrients, its protein content is 3%-6% higher than that of normal corn, and its lysine and tryptophan content is higher. Fresh green corn kernels are soft, fragrant, thin, no residue, good palatability, and easy to digest and absorb. The mature grain processing products have unique characteristics. The grains are porridge, which resembles pearls, which are thick and sticky and rich in nutrition. Together with red dates, red beans, and longan, they can be made into eight-treasure porridge with pearls, regulate the dietary structure, and are used for unique food processing. Competitive Advantage.
Special maize is an emerging economic crop with low input and high output. The average fresh yield per sweet potato per acre is generally 750-800 kilograms. The direct economic benefit is over 1000 yuan. The net income of two years of production in a year is 2000. Yuan above. Special maize planting is one of the major high-efficiency crops and specialty industries in Guangdong, Shandong and Anhui provinces.
It is understood that in recent years special corn has been planted in cities and districts under the jurisdiction of our city, but the planting development of special corn has a considerable distance from market demand. Small scale, few varieties, short supply period, etc., coupled with deep processing and follow-up industries can not keep up, economic efficiency has not been effectively played.
Since Zhenjiang City is located in the southern hilly corn area, the hilly dry land and the sandy land in the lower reaches of the Yangtze River have good soil and climate advantages. The special corn produced has high quality and good taste, and has favorable conditions for the development of special corn. The author believes that to develop the special corn article, first of all, the agricultural departments at all levels, especially the agricultural technology promotion departments, must promote the potential and economic benefits of special maize production in the region, promote typical examples and technical points, and develop Special corn has become the conscious behavior of farmers. Second, we must investigate and study the development of local special corn production land, climate, technology, etc., find out resources, conduct scientific argumentation, and formulate development plans. Once again, we need to filter out suitable new varieties that are suitable for planting, form flagship products, and achieve a one-year-old cropping system that focuses on the summer harvest of maize production, and change to a three-matured one-year system for spring, summer and autumn harvests; Production of economical fresh pods and kernel corn transformation; from the production of ordinary hybrid corn to sweet corn, white waxy corn, black glutinous corn and other diversified development. Finally, post-harvest corn services should be improved to improve the overall economic efficiency. While doing a good job of providing technical services, supporting services such as seeds and other means of production, it is necessary to actively guide farmers to take the road of combining grain, economy, and feeding, and planting, raising, and increasing. At present, the sweet corn processing enterprises that have come into being in Guangdong Province have processed sweet corn into grainy, mushy, and bamboo-like cans and processed them into quick-frozen corn kernels and corn cobs, and some have used microwave sterilization and vacuum packaging technology to process sweet corn pods. Making sweet corn, making drinks, etc. To achieve multi-level value-added, so that farmers from various aspects improve the overall economic benefits of corn production, and increase production and income.
