The Latest Methods for Pre-Sowing Treatment of Wheat Seeds
Wheat is one of the main food crops in our country, and it is planted across a wide area in our country. Our country now consumes as much as several hundred thousand tons of wheat every year, and the yield and quality of wheat are closely related to the quality of the seeds. Therefore, before sowing, we all need to do a good job of disinfecting the seeds and hastening germination. So how should wheat seeds be treated before sowing? Now let the editor introduce it to everyone below!
1. Seed selection
The selection of seeds is very important. After we have chosen high-quality seeds, we then need to screen the seeds once more, picking out insect-damaged, diseased, shriveled seeds and impurities. Pay special attention to whether there are wild wheat grass seeds or degenerated seeds. This can ensure that the seedlings grown are high-yielding and uniform, and it can also reduce the cost of weeding. When selecting seeds, if the quantity of seeds is not large, just screen them out with a sieve. If the quantity of seeds is large, then it is best to prepare a seed selection machine, which is both simple and able to guarantee seed quality.
2. Sunning the seeds
Wheat seeds need a certain amount of time to germinate and emerge, usually about one week. When sowing, we should hasten the seed emergence rate as early as possible, because the earlier the emergence, not only can the nutrients inside the seed be fully utilized, enabling the seedlings to quickly unfold three true leaves, but it can also allow photosynthesis to begin as early as possible and improve the growth capacity of the seedlings. Therefore, in order to advance the emergence time, we should break the seed dormancy period as early as possible. So before sowing, choose a sunny day and put the seeds under the sun to sun them, which can effectively bring the seed dormancy period to an end.

Seed dressing can reduce pathogens on the seeds or pest pathogens in the soil. That is, mix water with the chemical agent and then stir it together with the seeds. When dressing seeds, we should proceed with a clear purpose according to common pests and diseases and soil-borne diseases. Therefore, it is generally mainly systemic fungicides and insecticides. Some farmers are used to using micro-fertilizers for seed dressing; this kind of seed dressing method can only improve the seed germination and emergence time and has no sterilizing effect. We should use agents such as triadimefon for seed dressing about 2-3 weeks before sowing, which can inhibit the occurrence of diseases such as rust and powdery mildew. We should stir it fully, then seal it and leave it for about 2 days.
4. Seed soaking
The main purpose of soaking seeds is to improve the germination capacity of wheat seeds. First, we need to soak the seeds in warm water at about 53 degrees for about 12 minutes, then take them out and immediately put them into cold water to soak for 5-6 minutes. Then put them into warm water at 55 degrees, and repeat this cycle 7-8 times. This can effectively improve the germination capacity of the seeds and also have a sterilizing effect. Then you can also use quicklime mixed with water to soak them for 1 day, then take them out and air-dry them ready for sowing; the effect is about the same.
When using quicklime to soak seeds, we should note that it is best to use new lime, and do not use lime that has been opened and stored for too long. During the soaking process, the seeds must not be stirred, to prevent losing the seed soaking effect. That is all for today's introduction.
