Wheat lodging has seriously reduced production. How to prevent wheat lodging?

"The wheat pours a handful of grass, and the grain pours a handful of chaff." Too much sowing amount and improper fertilization in the growing period of wheat will lead to excessive stalk lodging after jointing, which will affect the later yield. How to prevent it is better?

First of all, we should determine the appropriate sowing time and amount according to our actual situation. For example, for sowing in mid-October, the sowing amount is generally 1-12 kg; It is suggested that the sowing amount per mu planted in late October is 12-15 kg. Reasonable sowing amount is beneficial to cultivate strong seedlings and improve the lodging resistance of wheat.

Secondly, before winter, if the wheat seedlings are too dense and grow vigorously, it can't be fertilized again, so it is necessary to choose the control chemicals and cooperate with the measures of suppressing soil moisture to improve the frost resistance of wheat. Pre-winter repression is generally carried out in the middle and late November to promote strong wheat seedlings to survive the winter; The way of repression can be crushed with small stones or hollow iron.

The third turning green period is the period when wheat needs water and fertilizer, but how to use water and fertilizer depends on the growth of seedlings. For large and well-growing wheat seedlings, fertilization should be delayed, and for prosperous wheat, topdressing should not be done for the time being, and products such as paclobutrazol, calcium cyclamate and uniconazole should be used to control the growth, and the dosage should be used according to the instructions. For example, 4 grams of 15% paclobutrazol per mu is sprayed with 3 kilograms of water. It is also possible to enhance the strength of stem fibers and improve the lodging resistance by spraying potassium dihydrogen phosphate on the leaves for many times.

The measures to reduce the loss should be selected according to the lodging period of wheat, and the management of the early lodging field should be strengthened, and the lodging from the late filling stage to the mature stage only needs to be drained and harvested.

Summary

In the field management of wheat planting, if wheat lodging occurs, it is suggested to take scientific and reliable rescue measures in time, which is conducive to minimizing the losses caused by wheat lodging.
