Problems solved by technology

[0002] For watermelon hybrid seed production, in order to improve the purity of seed production and prevent mixed harvesting or artificial mixing, the method of marking after pollination is generally used, so that in the entire seed production process, the purity of seed production caused by human or other factors can be effectively controlled. Insufficient, which will bring losses to the seed farmers and producers, so the hybrid seed production marking method is adopted. At present, the watermelon hybrid seed production marking methods commonly used by world-class companies are tie lines or band rings, or use printing oil to mark Obviously, but this method also has certain defects, mainly the following points:
[0003] 1. The labor cost is high. The use of tie wires or belt rings, or printing oil will undoubtedly increase the labor cost. According to the current average of 100 labor calculations per acre of watermelon hybrid seed production, the average daily labor cost in Gansu is 150 yuan per day, and the accumulated labor cost The cost is 15,000 yuan, and the labor cost is relatively high
[0004] 2. Increased production cost, no matter it is commonly used nylon thread or plastic ring, at 0.03 yuan per piece, 20 flowers per plant pollination, 4000 plants per mu, the cost is about 2400 yuan, which is relatively high
[0005] 3. The accuracy of marking is greatly affected by human beings. In actual operation, through tying wires or belt rings, through human touch with limbs, or during the ripening and picking of watermelons, it may fall off. Spraying pesticides or raining will cause the marks to fall off slowly, making it impossible to truly judge whether pollination is true, affecting the accuracy of seed production and indirectly affecting the purity of seeds

Embodiment Construction

[0013] A watermelon hybrid seed production marking method, its specific implementation and principle are as follows:

[0014] The principle of sepal removal marking method: To understand the technical scheme of sepal removal method, first of all, we must understand the structure and function of watermelon sepals. Watermelon sepals are mainly 5-7 egg-shaped, wrapping petals, with a small amount of thorns and covered with fluff. , the sepals and petals have the function of protecting the internal structure of the flower before the flower opens. The sepals contain a variety of chemical substances, such as flavonoids, and special fluorescence can be seen under specific wavelengths such as ultraviolet light. This fluorescence can attract and guide the corresponding Insects come to suck the dense flowers to help spread pollen. The sepals of watermelon are permanent unless they are removed artificially. It will exist permanently throughout the growth and development process and is un...

Abstract

The invention provides a marking method for hybrid seed production of watermelons, and relates to the technical field of hybrid seed production of the watermelons. According to the technical scheme, the method comprises the steps that after pollination for hybrid seed production of the watermelons is completed, a flower stalk of a flower subjected to pollination is held with the left hand, and then two sepals are torn off from the root with the right hand, wherein actions need to be conducted gently. According to the marking method for hybrid seed production of the watermelons, marking can be conducted without tying a thread or putting a ring or smearing stamp ink, the cost is low, and the accuracy is high.
