What should I pay attention to when mixing wheat seeds?

Chemical seed dressing in wheat sowing can not only increase the yield, but also prevent diseases and insect pests, but if the seed dressing is not operated properly, it will not only not play the role of increasing production and preventing diseases and insect pests, but also slow and uneven emergence of wheat seedlings. there may even be the phenomenon of not going out. So what should we pay attention to when mixing wheat seeds? Let's take a look.

1. Determine the type of medication.

First of all, it is necessary to choose good types of drugs according to the local diseases and insect pests, if the local environment has less pests at the seedling stage, but the disease is extremely important, then seed dressing only needs fungicides without adding insecticides; on the contrary, only pesticides are added. No need to add fungicides. However, if it is the phenomenon of mixed diseases and insect pests, it is necessary to mix seeds with fungicides and fungicides at the same time. If the underground pests are more serious, seed dressing can not achieve the desired effect, so the combination of seed dressing and soil treatment can be used for comprehensive control.

2. Pay attention to the dosage

When mixing seeds, the dosage of chemicals is very serious, and some farmers use drugs based on their feelings when mixing seeds, blindly increasing the dosage, which may be counterproductive. According to the practice, if the dosage of triadimefon and octane scale is too much, it will cause drug damage to the seeds, resulting in delayed emergence and slow growth of wheat seedlings, and the phenomenon of lack of seedlings and death of seedlings will occur in serious cases. Therefore, drugs must be used strictly in accordance with drug standards, and must not be used blindly.

3. Main seed dressing methods.

In seed dressing, it should also be noted that the concentration of some chemicals is too high and the medicine is strong. If not treated reasonably, seed dressing directly may damage the seeds. When using phoxim and other medicament to mix seeds, we should first reduce dilution with water, then mix seeds, sow seeds after covering heap, and then sow seeds with pentachloronitrobenzene, strychnine and Likexiu. First of all, the seeds should be wet before sowing, and then dry sowing. If you mix seeds with insecticides and fungicides, first mix pesticides, then mix fungicides after heap stew, and then sow seeds.

4. Mix with broadcast

Generally, when mixing seeds with sowing, the time is not too long, so as not to reduce the efficacy. Generally, after mixing seeds with insecticides and stewing for 2-3 hours, the seeds can be sown after the medicine is absorbed by the seeds. After dressing seeds with fungicides, it should be understood that sowing seeds or dry seeds after sowing, if the heap stew time is too long or seed mixing for a long time, it is very easy to produce drug damage.
