Brassinolide, sodium nitrophenolate, and diethyl aminoethyl hexanoate are all good plant growth regulators on the market, and their mechanism of action and function are similar, so what are the differences between them? Many farmers and friends don't know how to choose better results. Today, I will share with you the relevant knowledge about brassinolide, sodium nitrophenolate, and diethyl aminoethyl hexanoate. Let's find out together!
1. The mechanism of action of brassinolide, sodium nitrophenolate and diethyl aminoethyl hexanoate is different
Brassinolide is one of the endogenous hormones of plants, that is, it is inherent in plants and can directly act on crops. Sodium nitrophenolate is a cell activator, which can increase the fluidity of cell fluid. Its mechanism of action is to promote the delivery of nutrients from leaves to fruits, as well as to seeds, balance endogenous hormones, and promote seed development, but it is not. The plant itself, so it also plays an indirect role. And diethyl aminoethyl hexanoate itself is not a hormone that comes with plants, that is to say, the plant itself does not have it, and we supplement it later. Its mechanism of action is indirectly by regulating the balance of endogenous hormones in crops. It can improve the activity of peroxidase and nitrase, and can synthesize the nutrients made by leaves. The more molds produce more nutrients, it can adjust the balance of water in the plant and enhance the cold resistance, drought resistance and stress resistance of crops. The senescence of plants, from this point of view, we can see that these three diethyl aminoethyl hexanoate have the best effect on improving crop quality and yield.
2. Brassinolide, sodium nitrophenolate, diethyl aminoethyl hexanoate, different requirements for ambient temperature
Brassinolide is the endogenous hormone of the plant itself. As long as the plant has a certain temperature, it can work, so its starting temperature is 20 degrees. The higher the temperature, the faster it will work. The effect of using it is not so obvious. When the temperature is higher than 30 degrees, the effect of its own brassinolide is greater, so we should pay attention to the concentration when supplementing the brassinolide. If the concentration is high, it will be poisoned.
Let's look at sodium nitrate again. Its minimum temperature is 15 degrees, and the effect is enhanced when the temperature reaches 25 degrees or more, and it can take effect within two days. When the temperature reaches 30 degrees, the effect is more obvious, and it can take effect within 24 hours. Therefore, through the above analysis, sodium nitrate is as the temperature increases, the greater the activity, the better the effect.
The familiar point of aminoethyl hexanoate is that it works as long as the plant is alive, as long as there is temperature. Therefore, it can be used at low temperature, and it can synthesize enzymes and hormones. Therefore, diethyl aminoethyl hexanoate is widely used in greenhouse winter crops and some crops grown in early spring, such as watermelon, strawberry, etc., which can be used at very low temperatures.
3. Brassinolide, sodium nitrophenolate, diethyl aminoethyl hexanoate have different durations
Brassinolide acts directly on crops, and the effect is the fastest, but the duration of effect is relatively short, that is, 10 to 15 days. Let's take a look at sodium nitrophenolate. Its onset period is the slowest. It can only work after 2~3 days of use on crops, and the lasting period can reach about 25 days. And diethyl aminoethyl hexanoate is different from them. It can be used in part, and part of it can also be stored by crops, which can be released slowly and the water will flow for a long time. Therefore, its effect adjustment time will be longer, and the general duration can reach about 30 days.
4. Brassinolide, sodium nitrophenolate and diethyl aminoethyl hexanoate have different photosynthesis enhancement abilities
Diethyl aminoethyl hexanoate and sodium dinitrate have the strongest ability to enhance photosynthesis, and brassinolide has the weakest ability among them. Therefore, for use in greenhouses, we prefer to use diethyl aminoethyl hexanoate and sodium dinitrate, because they are better than brassinolide in low light conditions.
5. Brassinolide, sodium nitrophenolate and diethyl aminoethyl hexanoate have different stress resistance in crops
It is undeniable that aminoethyl hexanoate is the best, followed by sodium dinitrate, but sodium dinitrate has a better fertilizer utilization rate and efficacy than those two. Brassinolide is slightly worse in stress resistance.
So when we choose these three regulators, we should choose according to different crops, different temperatures, and different concentrations.
