Chinese cabbage hybridization breeding marking method

Abstract

The invention discloses a Chinese cabbage hybridization breeding marking method, and relates to the technical field of Chinese cabbage hybridization breeding. According to the technical scheme, the method comprises the steps that after Chinese cabbage hybridization breeding pollinating is finished, a flower stalk of a pollinated flower is held by the left hand, and then two sepals are removed from the base with the right hand, wherein the actions need to be light. According to the method, marking can be conducted without needing line tying or ring bonding or stamp-pad ink applying, the cost is low, and the accuracy rate is high.

Description

technical field [0001] The invention relates to the technical field of Chinese cabbage hybrid seed production, in particular to a marking method for Chinese cabbage hybrid seed production. Background technique [0002] In Chinese cabbage 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 during the entire seed production process, the seed production caused by human or other factors can be effectively controlled. The purity is not enough, which will bring losses to the seed farmers and producers. Therefore, the hybrid seed production marking method is adopted. At present, the Chinese cabbage hybrid seed production marking methods commonly used by world-class companies are tie lines or rings, or use printing oil. , the mark is obvious, but this method also has certain defects, mainly the following points: [0003] 1.

Problems solved by technology

[0002] For Chinese cabbage 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 during the entire seed production process, the seed production caused by human or other factors can be effectively controlled. The purity is not enough, 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 Chinese cabbage hybrid seed production commonly used by world-class companies are tie-lines or rings, or printing oil. , the mark is obvious, 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 Chinese cabbage hybrid seed production, the average daily labor cost in Gansu is 150 yuan per day, accumulative The labor cost is 15,000 yuan, which 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 thread or belt ring, through artificial touch of limbs, or during the ripe picking process of Chinese cabbage, it may fall off. Spraying pesticides in the field 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
