Environment-friendly method for preventing corn female ear bags from falling off

Abstract

The invention discloses an environment-friendly method for preventing corn female ear bags from falling off. The method is characterized by including the following steps that when female ears expand and before filaments are exposed out of bracts, 45-degree angles are formed through bending in the horizontal direction of leaf surfaces and at the positions, 10 cm away from leaf sheaths of stalks, of corn cob position leaves, and sheep skin paper bags 18 cm in length and 11 cm in width are wholly put in the corn cob position leaves and the female ears in a sleeving mode and embedded into the bonding positions of the leaf sheaths and the stalks. According to the method, the 45-degree angles are formed through bending in the horizontal direction of the leaf surfaces and at the positions, 10 cm away from the leaf sheaths of the stalks, of the corn cob position leaves, then the sheep skin paper bags are wholly put in the corn cob position leaves and the female ears in the sleeving mode, the sheep skin paper bags are supported through the corn cob position leaves, the bags are fixed by themselves in the mode that the female ears and the bent portions of the corn cob position leaves naturally grow to form expansion resistance with the sheep skin paper bags, the problem that the bags fall off in the bagging period is solved, and the influence of reduction, caused by breaking of the corn cob position leaves, of the selfing line hundred-grain weight is avoided.

Description

Technical field: [0001] The invention relates to a bagging method for ear ears of inbred lines in the corn breeding process, and belongs to the technical field of agricultural crop genetics and breeding. Background technique: [0002] Bagging pollination is an arduous and hard work in maize breeding. Corn is a monoecious plant with different flowers. In the process of corn breeding, the method of artificial bagging and pollination is often used for each corn inbred germplasm to isolate the mixing of foreign pollen. If the bag is not tight or the bag is not tightly packed, it will be skewed and the bag will be dropped. The falling of the paper bag will cause the filament to be exposed to the air and form a runaway silk. This plant will become an invalid ear. Corn bagging and pollination technology is the most basic field operation technology in the breeding process. It runs through the whole process of corn breeding. Using correct and effective bagging operation technical re...

Problems solved by technology

This method is time-consuming and labor-intensive in actual use, and at the same time as the high cost of large-scale manual labor, there are injuries caused by the natural fall of the pins and the fall of the manual operation (including the next stubble injury caused by the residual soil of the pins), corn The flowering period is short, and the workload of self-crossing and test crossing of corn inbred lines is heavy. Therefore, it is urgent to find an environmentally friendly method to prevent corn ear bagging from falling off in order to solve the high cost of operator safety and labor-intensive corn ear bagging process. question
