With the drop in temperature and the arrival of rain in recent days, many farmers have begun to prepare for wheat sowing. A necessary step before sowing is to mix seeds. In addition to mixing with insecticides and fungicides, you can also mix brassinolide and potassium dihydrogen phosphate. Mixing them will make the wheat seedlings grow evenly and strong. So how to use brassinolide and potassium dihydrogen phosphate to mix wheat?
How to use potassium dihydrogen phosphate to mix wheat?
Based on the experience of the past few years, it is generally recommended that farmers use 30 grams of 99% potassium dihydrogen phosphate to mix 30 to 40 kilograms of wheat. This amount is safer! Why is it recommended to mix wheat with potassium dihydrogen phosphate? There are two main benefits!
First, mix potassium dihydrogen phosphate on the surface of wheat seeds. As the seeds absorb potassium dihydrogen phosphate, a large amount of phosphorus (root promotion) and potassium (metabolism promotion) are supplemented, which is conducive to the reproductive growth of seeds, so that they begin to germinate and take root, and also improve the resistance of seeds to adverse environments such as drought. Secondly, a large amount of phosphorus and potassium supplementation reduces the advantage of nitrogen in the plant body, indirectly plays a role in controlling seedling growth, so that more nutrients are used for rooting. With a good root system, wheat will naturally grow strong!
Pay attention to mixing potassium dihydrogen phosphate with wheat. Don’t use too much. Too much may cause a significant delay in wheat seedling emergence. If there is heavy rain again, it is very likely to cause the seeds to be suffocated!
How to use brassinolide to mix wheat?
The biggest advantage of using brassinolide to mix wheat is that it can break seed dormancy, promote wheat germination, promote rooting, and improve resistance to adverse environments such as drought. This effect is of great benefit to straw return plots.
Under normal circumstances, when we use brassinolide to mix seeds, we can choose 10g of 0.01% 24-epibrassinolide to mix seeds with 30 kilograms. If it is 14-hydroxybrassinolide, 5g can be used to mix seeds with 30 kilograms. This dosage is relatively safe based on current experience. Try not to exceed 10g. The more brassinolide is used, the better. Using too much will inhibit growth!
Precautions for mixing wheat with potassium dihydrogen phosphate and brassinolide
Some growers will ask, after mixing brassinolide and potassium dihydrogen phosphate, can I mix insecticide and fungicide seed dressing agents? The answer is of course yes. We can use brassinolide, potassium dihydrogen phosphate and insecticide and fungicide seed dressing agents together. There is no problem with safety! However, when using it, it is recommended that 30 kilograms of seeds be mixed with at least 500 ml of water (that is, one kilogram of water) so that they can be mixed evenly to avoid excessive concentration and damage to seeds!
Some growers will ask, when should brassinolide and potassium dihydrogen phosphate be mixed with wheat? As for the time of seed mixing, you can mix it a few days in advance or on the day of sowing, but after mixing, you must put it in a cool place to dry before sowing!
There are more extreme weather this year, either drought or flooding. When mixing seeds to prevent diseases and insects, adding potassium dihydrogen phosphate and brassinolide can indeed greatly increase the germination rate and improve resistance to adverse environments such as drought; and for plots where straw is returned to the field, through the effects of brassinolide and potassium dihydrogen phosphate, the roots of wheat can grow longer and stronger, which can largely solve the problem that the roots of wheat cannot enter the soil due to the lack of soil, and thus die. So if wheat is not planted this year, you can add brassinolide and potassium dihydrogen phosphate when mixing seeds!
