What to do if corn is blown away by the wind

1. Male accommodation before and after pollination. When you board, you should start lifting it. At the same time, you need to cultivate the roots of the corn with soil. It is best if two people work together. One person grabs the top of the corn plant and gently pulls it upward, while the other person builds soil around the roots. The height from the ground should be 6 to 8 cm. Once the soil is cultivated, press it firmly with your feet. It is best to water and help on the same day, no more than 3 days. Three days later, you can't take it anymore. If you help injured roots, it will reduce the yield even more. 2. The female ear falls off after being torn off. Moderate lodging (at an angle of 30 to 60 degrees to the ground), collect it manually according to the above method, or after 3 to 5 straightened corns, tie the straw with a string at the level of the corn cobs. It is best not toas prick the corn husks. Cut off the binding rope after 3 days and let the corn grow naturally, which will have little impact on the subsequent filling and yield of the corn. 3. Assuming that the stalks and roots are not damaged, all pouring corn plants can be supported with wooden sticks under the cobs so that the corn cobs are about 30 cm above the ground to avoid rats and mold. While lifting and supporting plants, it can be combined with the destruction of lower leaves to improve ventilation and light transmission; a fast-acting nitrogen fertilizer can be applied to increase nutrition and promote maturity.

Why did the corn fall even though there was no strong wind or rain?

Corn can still survive if it is blown away by the wind.

If the plants are in the seedling stage and the soil is relatively moist and soft, they maycan be raised.

But in the middle and later stages, the straw is relatively hard. and if it falls to the ground badly, there is no way to lift it, otherwise it will break very easily. And because corn that has fallen due to wind and rain has a certain ability to stand upright on its own.

What to do if the corn is too tall and blown away by the wind

There are two common corn drop situations: root drop and stalk drop

Root fallThe corn plant does not bend or break, and it falls sideways towards the root in the wind. Root failure often occurs after corn heading, caused by wind and rain or wind after watering. If the roots fall off at the beginning of gestation, the plant will bend and “straighten up” normally, which will not cause great damage to production. The roots will fall off in the final stages of reproduction,particularly between the stage of maturity of milk and that of wax. , which is more harmful to grain injection cultivation. If the plants are too large, the yield will be limited. After the plants have fallen, the upper end of the flower spike can be bent and "stand up", and the lower part of it can be bent and "raised". the flower spike generally no longer “stands upright”.

Stem dropThe position where the roots of the corn plant are fixed in the soil will not change, but the middle and upper parts of the plant will become deformed. Stem failure often occurs in excessively dense soils or on varieties with good stem extensibility, especially varieties with taller panicles and slightly larger flower spikes. The root system of the corn plant is fixed in the soil, and the stem is broken directly without bending.

Sectional folding: The common foldingthat we use is carried out a few days before the corn panicle until the bread-making period, when there is a moment of strong wind. The corn plant is quite brittle and brittle, usually on the second to fourth node at the end of the plant. The inversion is linked to the genetics of the variety. Generally speaking, varieties with the terminal node exposed outside the petiole are prone to inversion. After folding, it has virtually disappeared.

Internode Inversion: When I was studying varieties with my friends a few days ago, I discovered that a certain variety also has an inversion. When I asked the producer about the situation, the producer stated that there have been no reversals in the last month. It was a rainy day and there was no strong wind. It is not normal for the bend to appear without strong wind and heavy rain. At first I suspected that this was due tohuman factors. Later I found out that this was happening repeatedly in the same location, and the same turn was happening in another plot. and the breakout position was at the Bit node.

After careful observation, we found that the top of the plant was brown, then we dug into the root system and found that the root system was also brown and diseased. the reversal was stem rot. This is why we must observe carefully when inspecting varieties. Only in this way can we discover the real reason.

Quick solutions: quickly promote corn lodging, prune damaged corn and strengthen soil management.

1. Quickly support lodging corn

When the corn is blown away by the wind, we must take timely measures to support the lodging corn. This can useUse wooden sticks, bamboo poles and other materials to support the lodging corn to prevent it from continuing to lodging and affecting normal growth. Meanwhile, some support rods can also be reinforced around the corn to improve its stability.

2. Prune damaged corn

Once corn is blown away, some damage will often occur, such as broken or damaged leaves and stems. parts. At this time, we must prune the damaged parts in time to avoid affecting normal growth. When pruning, be sure to retain enough leaves and stalks to ensure nutrient supply and normal corn growth.

3. Strengthen soil management

Soil is an important basis for corn growth. Therefore, strengthening land management is also one of the important measures to be taken. solve theproblem of corn blown by the wind. First of all, maintain soil moisture to avoid drought and lack of water. Second, fertilization must be strengthened to provide sufficient nutrients to corn. Finally, pay attention to loosening and weeding to keep the soil breathable and soft.

The entire growth period of corn

The life of corn from sowing to the maturity of the new grains. Generally, the number of days from sowing to maturity of corn is called the full growing period, and the number of days from emergence to maturity is called the growing period. The length of the growing period and the level of yield are related to factors such as. as varietal characteristics and environmental conditions.

The accumulated active temperature required for a certain variety during the entire growing period (the sum of daily average temperatures ≥10°C during the growth period) is basically stable. The growing period will be shortened appropriately when. Growing in higher temperature conditions, the growth period will be extended appropriately at lower temperatures. In terms of production, it is generally divided into five categories: early, medium-early, medium, medium-late and late.

The planting methods in corn dry areas are mainly corn monoculture and spring planting. The territory is vast and the ecological conditions vary greatly. The frost-free period increases from north to south. The frost-free period in major corn planting areas is 130 to 180 days. The accumulated active temperature increases from north to south, with an average of around 3,100 °C. of spring corn varies greatly, generally between 100 and 135 days.
