Cultivation measures to prevent the lodging of millet

1. According to the research, the lodging of millet stalks is closely related to the plant shape. The lodging resistance varieties should exhibit the following characteristics in the plant shape: one is that the plants are not too tall, generally below 10 cm; the second is that the base stalks are shorter and thicker; the third is that the leaves are distributed from bottom to top in a tower or spindle shape and The growth is compact; the fourth is that the ear stem section is shorter, and the sagging angle is smaller when the ear is mature.

2. The purpose of seedlings during seedling stage seedlings is to promote root development, control the growth of aboveground parts, thicken the base of stems, and improve the lodging resistance of plants. The seedlings can be pressed when the millet seedlings grow 2 to 3 leaves. If the seedling stage is dry, it is necessary to properly control the surface water and try not to water.

3. In the morning seedlings to ensure the whole seedlings, the seeding rate of millet is generally much larger than the number of seedlings. Millet seedlings grow crowded, fighting each other for water, competing for fat, glory, will cause weak growth of individual plants. If it is less than time, it will affect the later development, form a weak strain, and reduce the lodging resistance. According to the research, the seedlings of millet in the 3~5 leaf stage are more suitable, and the yield increase effect is better.

4. Strengthening cultivating and cultivating soil in cultivating soil is an important measure to promote root development, make the internodes of the base thick and strengthen the lodging resistance of plants. The cultivating and cultivating soil is generally carried out at the booting stage of the millet, and it is better to combine the measures of topdressing and irrigation.

5. Reasonable topdressing and watering and topdressing is a supplementary fertilization method to solve the problem of insufficient base fertilizer. The period of topdressing and the improper quantity can also cause serious lodging of the millet. Therefore, it is necessary to rationally topdress the fertilizer according to the fertilizer demanding period of each season of millet, and the number of seedling period and heading period is generally smaller, while the jointing period is larger. During the growth period of millet, the water needs to be more than the jointing and booting stage. During this period, sufficient water supply should be ensured. In the later stage, if it is dry, it can be lightly poured without flooding to prevent the roots from loosening in the windy days.

6. The timely prevention and control of the heartworm is the ash mites, and the larvae are harmed by the stalks of the millet. The part of the stem that is smashed into a tunnel is prone to breakage when the wind is encountered, causing the plant to fall. It is necessary to prevent and control the heartworm early. Generally, in the seedling stage, it is necessary to remove the dead seedlings appearing in the field, and spray 500 times of the trichlorfon pesticide to kill the insects when the seedling height is 16 to 19 cm.
