How to use plant growth regulator most effectively

Mention plant growth regulator must be known to farmers friends, plant growth regulator can promote the growth of crops, agricultural products increase production and income depends on it, but the use of plant growth regulator is not as simple as imagined, let's understand it together.

Proper use of plant growth regulators:

1. Select suitable varieties for timely use. Plant growth regulators have different effects due to different crop types, growth stages and action sites. The product should be selected according to the function on the product label and used strictly according to the use method on the label during the appropriate use period.

2. Master the concentration and frequency of application. Plant biofodulators are not "oily vegetables". It should be used strictly according to the label, and flexibly controlled according to the variety type and application purpose of plant growth regulator, crop growth period and performance, weather conditions and other factors, otherwise it will get the opposite effect. For example, auxin promotes root growth at low concentration, but inhibits growth at high concentration.

3. Use evenly. Some regulators, such as gibberellin, do not move in the body of the plant, just as a fruit treated with only half will cause the treated part to increase and cause malformed fruit, so attention should be paid to uniform and meticulous application.

4, can not replace fertilizer with medicine. Even a stimulant regulator can only work if there is plenty of fertilizer and water. Although some plant growth regulators add some concentrated nitrogen, phosphorus, potassium and trace elements, but the content is small, the effect is not big, do not think that crops green and strong do not lack of fertilizer.

5. Do not use in the remaining farmland. Plant growth regulators such as ethrel and gibberellin are used in vegetal, cotton, wheat and other vegetative and retained crops. Although they play the role of early maturing and increasing yield, they will cause more non-booting heads and seriously reduce the germination rate of seeds, so they cannot be used as seeds. Therefore, plant growth regulators should be used with caution in the use of seed - retaining crops.
