The causes of corn lodging and its solutions

Reason 1: high planting density

In the case of too dense planting, the chance of lodging is much greater than that of reasonable dense planting. The planting density is large. When the corn is in the middle and late stages, the field ventilation and light transmission will be relatively weakened, and the growth of the corn will be blocked, affecting normal photosynthesis. Developed, are prone to lodging.

Solution: Reasonable dense planting is very important, but how many plants are planted per acre of land is determined by various factors such as soil fertility, variety, local climate, etc. Generally, most of 4500-5000 plants per acre of land, Of course, there are also areas where 7,000 plants are planted, as well as areas where 3500 plants are planted.

Reason two: planting management

The management of corn during its lifetime is very important. Generally, it mainly includes diseases, insects, grass pests, and control. For example, when there are too many weeds in the field, it competes with corn for water and nutrients, and it is also a parasitic place for some diseases and insect pests. Affects the normal growth of corn, which is prone to lodging; the harm of pests and diseases will be more obvious. In severe cases, the whole corn will die and it will definitely fall.

The causes of corn lodging and its solutions

Solution: For the management of corn diseases, insects and weeds, we must not ignore them. We should also deal with them in a timely manner. The best control period for weeds is the 3-5 leaf period. It is recommended to prevent diseases and insect pests in advance. If the field has already occurred, the sooner The better the prevention.

Cause three: soil problems

This point will be ignored by many farmers. If their own soil is not properly applied with fertilizers, pesticides, or other factors for many years, it will cause soil acidity and alkali imbalance, and symptoms such as compaction will occur. After the corn is grown, it will not be normal. Growing, it is prone to lodging.

Solution: Add rotten farm fertilizer, and control the use of chemical fertilizers and pesticides.

Reason four: water and fertilizer

The factors of water and fertilizer are generally put together. If the field is too rich, corn growth is prone to prosperous. If the crop is not controlled in time, the corn stalk is too high, but it is relatively thin. At the same time, the prolonged growth will lead to underdeveloped root systems. In the middle and late stages, lodging is easy to occur.

Solution: Water and fertilizer are suitable. We often say that reasonable fertilization and reasonable irrigation mean this. Excessive application of water and fertilizer will also increase costs and is not conducive to increasing income.
