Method for marking maize hybrid seed production

Abstract

A marking method for corn hybrid seed production relates to the technical field of corn hybrid seed production. The technical plan is as follows: after the pollination of corn hybrid seed production is completed, first pinch the flower stalk of the pollinated flower with the left hand, and then tear off two sepals horizontally from the root with the right hand, and the movement should be light. The present invention can be marked without tying thread, belt ring or applying ink, and has low cost and high accuracy.

Description

technical field [0001] The invention relates to the technical field of corn hybrid seed production, in particular to a marking method for corn hybrid seed production. Background technique [0002] For corn 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. Therefore, the method of hybrid seed production marking is adopted. At present, the marking methods of corn hybrid seed production commonly used by world-class companies are tie lines or belt rings, or printing oil, marking Obviously, but this method also has certain defects, mainly the following points: [0003] 1.

[0002] For corn 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. Therefore, the method of hybrid seed production marking is adopted. At present, the marking methods of corn hybrid seed production commonly used by world-class companies are tie lines or belt rings, or printing oil, marking 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 mu of corn 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 lines or belt rings, through human touch with limbs, or during the process of mature corn picking, it may fall off, and the printing oil can be passed through the field. 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
