How to Deal with Rainy Weather During the Wheat Harvest Period

Wheat is grown across a wide range in our country, and because the growing regions span a large area, its harvest time also varies widely. In some areas, wheat harvesting is inevitably affected by rainy weather. So what should be done when the wheat harvest encounters rainy weather? And how should it be remedied after harvest? Let's find out together.

1. What to do when the wheat harvest encounters rainy weather

If the wheat harvest encounters continuous rainy weather, you should seize the clear spells and hurry with mechanical harvesting, so as to avoid sprouting of the ears in the field, which would not only cause huge losses in yield, but also make the sprouted wheat basically unsellable, resulting in relatively large losses. After harvest, the shattered wheat should be dried in time; if it is not dried and aired promptly, it is very likely to sprout and rot.

2. Remedial measures

In the absence of drying equipment, the following three methods can be used as an emergency: (1) The natural oxygen deprivation method: this method is to improve sealing so as to create temporary oxygen deprivation in the wheat pile, thereby inhibiting the life activities of the wheat and achieving the purpose of preventing the wheat from heating up, sprouting and rotting. (2) The chemical grain preservation method: this method is to use chemicals to stir the wet wheat, so that the enzymes in the wheat are kept in an inactive state and it will not sprout. (3) The poplar branch storage method: it is to consume the moisture, temperature and oxygen needed for seed germination, so that the seed will not sprout; the transported branches with leaves have vigorous respiration, and when placed in the wheat pile they can consume the oxygen in the pile within a short time, keeping the wheat in a dormant state so that it will not heat up or sprout.

3. Points to note

Harvest at the right time. If harvested too early, the grains are not plump, the yield and quality are lower, and it is also not suitable for storage; if harvested too late, the grains are very likely to drop and the straw may lodge, which increases the difficulty of harvesting and causes relatively large losses. It is best to harvest on sunny days, which is good for drying and airing, and at the same time pay attention to severe weather such as thunderstorms and strong winds, so as to avoid wheat lodging and large-scale yield reduction. Do a good job of grain storage: newly harvested wheat should be placed in a warehouse with good ventilation, and at the same time it should be ventilated and aired regularly to avoid mold and affect wheat quality..
