How to prevent wheat lodging

After wheat planting, the problem most likely to occur in the event of rain is wheat lodging. There are many reasons for wheat lodging, but they are all related to the toughness of wheat stems and the weather. This kind of problem encountered in production shows that it must be combined with the situation. Local conditions to find specific lodging reasons, in order to improve, and, whenever you can think of reasons, you have to think of countermeasures before planting.

I. the cause of lodging +

Sudden strong wind and heavy rain weather, or other extreme natural disasters, a large area of lodging. Or the stem is long and slender, and it is easy to lodge under the influence of the outside world. Then there is a lack of fertilizer nutrition, resulting in thin and weak stems, unable to withstand the rain. There is the disease and insect damage to the base of the stem, causing lodging.

II. Preventive measures

1. Selection of species

During the planting period, we often pay attention to the weather, and we can cultivate the soil before the storm to increase the strength of the roots and resist the wind and rain. Choose a cultivated variety with a strong, tough stem, and then you can also plant it in a more leeward place. The variety selected is to be planted in practice, and the effect of rain separation is really good.

two。 Growth regulation

Growth regulators can be used to make the plant grow shorter and stronger, such as dwarf, or a certain concentration of gibberellin, which can shorten internodes, enhance root activity, make leaves wider, shorter, and more sturdy, so that they are not wrapped in the wind and are not easy to lodge. In the early use of the section, the effect is obvious, but the effect is not significant in the later stage.

3. Fertilization and irrigation

Adequate fertilization and irrigation to ensure good growth, not the time before jointing stage, control the amount of nitrogen fertilizer application, to avoid excessive stem thin and weak easy lodging. More potash fertilizer was applied at jointing stage to strengthen the stem and root system, so that the root system grew more and the stem was strong, which played an important role in fixing the plant. Do not accumulate water, if you accumulate water for too long, it is easy to rot and cause lodging.

4. Pest control

Many diseases occur from the base of the stem, and generally rot the rhizome after the disease, such as wheat blight, the rhizome blackened and rotted, and successively withered, and the disease may be extremely easy to lodge in the initial stage of wind and rain. 40% methyl isosphos EC 50ml or 50% phoxim EC 100ml spray can be used to control the disease. The main underground pest that harms the root is mole cricket. Mole cricket is good at digging soil and harms the root system. 10% imidacloprid can be used to control water irrigation root.

The above are the various causes of wheat lodging and the corresponding preventive measures, so that the problem of wheat lodging can be solved and improved. There are many reasons for wheat lodging, which have a lot to do with the specific local environment and climate, and perhaps there are reasons that have not been taken into account. Production practice has found that it can be solved by self-study.
