As the largest grain planting area in China, corn is the main economic source for farmers in many areas in China. Therefore, strengthening corn breeding, constantly developing high-quality special varieties, and promoting structural adjustment of corn varieties have become effective means for creating new economic growth points for farmers. In order to better carry out the breeding work and improve the efficiency and effectiveness of breeding, the breeding experts will use the plant lodging meter and other instruments to carry out the work during the breeding process, and use more professional instruments to do professional things.
In general, corn breeding is to maximize the advantages of corn varieties, improve the defects of corn varieties, breed new corn varieties with stronger production performance and disaster-resistance, and promote corn planting to increase production and income. We know that corn is a stalked plant. Although some maize has high yields, the plants are taller, and the stalks are softer, the stalk strength is low, and its lodging resistance is weak. Once it encounters severe natural weather, it is very It is prone to a large area of ​​lodging or inflection, which not only causes serious production cuts, but also causes great difficulties for machine harvesting. It is not conducive to large-scale corn planting. Therefore, an important direction of corn breeding is to improve the resistance of corn. Lodging ability. In order to effectively solve the problem of poor lodging resistance of maize, the maize varieties with strong lodging resistance can be screened by plant lodging counting and improved.
The application of plant lodging counting in maize breeding provides an important basis for selection of high quality, high yield, good resistance, moderate growth period, and high grain yield corn varieties. The toughness of corn stems has been greatly improved. The new varieties cultivated have quite strong anti-volt ability, which effectively improves the ability of the corn crops to cope with natural disasters. In the process of large-scale corn planting and production, the benefits of production are more assured, and it is easier to obtain mechanized harvesting conditions. The high yield meets the production needs of modern high-quality corn cultivation.
