The first domestic self-breeding hybrid, the marigold flower with 10,000 kilograms of flowers, was grown in the backyard of a farmer in Chifeng, Inner Mongolia. On July 11, the reporter rushed to the home of the Chifeng National People's Horticultural Science and Technology Development Co., Ltd. Chairman Liu Zhenting is located in the rural area near the Karasu Qiqi in Chifeng City to see his newly-selected hybrid pigment marigold. In his backyard of more than one mu of land, he planted dozens of cross combinations of marigolds, which were nearly 1 meter high, short and only knees, and varied in shades of light yellow, golden, orange and other flowers. Closely hanging on the branch. Pigment marigold is an ideal material for the extraction of natural lutein. Natural lutein is an excellent antioxidant, widely used in feed additives, food additives, pharmaceuticals, industrial dyes and other industries, currently only leaves extracted from a few plants such as kale, calendula and marigold Flavin contains only active substances that have antioxidant activity. Pigment Marigold flowers can be made into marigold granules by fermentation, pressing, drying, etc., and pigment essential oils can be prepared by solvent extraction. The marigold granules or essential oils produced in China, except for their own use, are mostly exported. Liu Zhenting picked two large honeycomb flowers and weighed them in the house. Each flower was more than 50 grams, and the diameter of flowers was more than 13 centimeters. He estimated the output to reporters: 1500 to 1600 strains per mu, each producing more than 120 flowers, according to an average of 25 grams per flower, the yield per hectare is 9,000 jins. If the management is better, the yield per hectare can exceed 10,000 yuan. jin. Liu Zhenting did not learn much about it. At first it was a brigade agricultural technician. He was promoted to a national cadre by seeking out two seed production techniques. He was elected as a model worker of the autonomous region, a scientific model of science in the country, a manager of a state-owned company, and the first time in the world to produce asters using the male sterile line. He is also a member of the International Holographic Society. Liu Zhenting told reporters, "I am about to introduce a breed that is hybridized with male sterility. The parent has been bred to the 6th generation, is not strong, the flower is a honeycomb, and it is unintentional. The color is orange and the ratio of petals to torus is 8: 2, the pigment content of 19 to 22, and the current domestic use of conventional varieties is about 16 ,, petal and tocoside ratio is 6: 4. Usually, the hybrid varieties are very resistant, flowering more than 10 times longer than conventional varieties The high yield, high quality, and disease resistance are the advantages of heterosis.†At present, the price of marigold granules with a pigment content of 17 在 is around 8,500 yuan per ton. On this basis, the pigment content increases by one thousand points, and the price increases. 500 yuan, if it can reach 20 miles, the price per ton is 10,000 yuan. It is understood that the pigmented marigold seeds currently used in China are conventional species imported from abroad or cultivated in China. The flowers are small and have the heart. The yield per mu is about 4,000 pounds, and the grower's mu yield is more than 800 yuan. Hybrids, the benefits will multiply exponentially. China is one of the main producing areas of pigmented marigolds in the world. In recent years, the planting area has increased rapidly. At present, it has passed 200,000 mu, accounting for one-third of the world's strength. Danish flower expert Dr. Nick Lai told Liu Zhenting after visiting the National Horticultural Company that how much hybrid pigment marigold seeds you produce will be collected. The market is too big. With the improvement of living standards, the chemical synthesis of pigments will surely be applied. Restricted, China's light market is incredible. Liu Zhenting told reporters that last year he supplied conventional pigmented marigold seeds to the 15,000-mu Daqing plant in Daqing. The planting area in Daqing next year will be increased to 100,000 mu, and he has decided to plant his newly-selected hybrids. "You can't be satisfied with the breed, you can only do tissue culture, and you can only provide millions of hybrid seedlings."
