The higher the plant height, the more resistant the corn is? Not the case!
A look at the underdevelopment of the root system. The developed system has a strong ability to resist lodging. On the contrary, it has poor resistance to lodging. Second, look at the length of the base of the stem. The shorter the internodes of the stem base are, the stronger the lodging resistance is, and on the contrary, the worse the lodging resistance is. Three to see the hardness and toughness of stems. This is invisible to our naked eyes, but the method is very simple, that is, in the middle and later stages of corn growth, slowly pull the corn stalk to 45 degrees by hand, remove the hand, and the straw will spring back to prove that the stem Hardness and toughness are good, and its resistance to lodging is strong. On the contrary, it has poor lodging resistance. The fourth is to look at the height of the ear (rather than see the height of the plant). Production practice has proved that a suitable ratio between plant height and ear position is 3:1, that is, plant height is 3 meters, ear position is about 1 meter, plant resistance to lodging is usually very strong, if the ear is 1.2 meters or even High, resistance to collapse will be much worse. According to an expert from the Ministry of Agriculture, there are two high-yield standards for corn: the higher the degree of uniform growth, the higher the yield, and the greater the potential for yield increase; the higher the plant height, the higher the yield and the greater the potential for yield increase. Therefore, it is simply considered that the higher the plant height of maize is, the worse the lodging resistance is. In addition to the high planting density is the main reason for corn lodging, the severity of lodging is also affected by seven factors, namely sowing depth, tuyere, ecological environment, fertilization amount, growth potential, fertilization type, arable land depth, soil texture and so on. In addition, corn in the jointing stage of large-scale flooding attack once, it is also easy to cause corn in the late lodging. The reason is that the jointing stage of corn is the most prosperous period of corn vegetative growth, and Dashui Dafei first attack is easy to form vegetative growth and reproductive growth disorders, that is, light and long trees, the internal tassel differentiation of the internal ear is affected, and in the end, either empty trees are easy to appear, or The internodes are elongated and the plant height increases, which brings hidden dangers for later lodging.
