5. Brassinolide

This product belongs to the sterol plant growth regulator, which can stimulate the intrinsic potential of plants, improve seed vigor, promote root development, regulate plant robust growth, improve fertilizer utilization, enhance crop resilience and increase seed setting rate. This product is compounded with other regulators or used alone, and can be used as an auxiliary drug for detoxification or disease prevention.

6.Indole 3 butyric acid IBA

This product is a plant endogenous auxin, which can enter the plant through the tender epidermis and seeds of leaves and plants. It can induce root primordium differentiation, rapid root opening and accelerate root growth with nutrient flow to the active site. And development, greatly increase the number of capillary roots and lateral root length, which is conducive to the formation of a large and strong plant root group, shortening the number of plant transplanting days, significantly improving the survival rate and stress resistance of transplanting; promoting tillering and strong seedlings; promoting root regeneration Strong plants, increase production and improve quality.

7. Gibberellic acid

This product is a plant growth regulator. Endogenous gibberellin is widely distributed in plants and is one of the important hormones that promote plant growth and development. It is an antagonist of growth inhibitors such as paclobutrazol and chlormequat. The medicine can promote cell, stem elongation, leaf enlargement, parthenocarpy, fruit growth, breaking seed dormancy, changing the ratio of female and male flowers, affecting flowering time and reducing flower and fruit falling off. Exogenous gibberellins enter the plant and have the same physiological functions as endogenous gibberellins. Gibberellins enter the plant mainly through leaves, shoots, flowers, seeds or fruits, and then conduct to active parts. It has a regulating growth and yield increase effect on cotton.

8. DA-6

This product has a regulating and promoting effect on cotton. It can increase the content of chlorophyll, protein and nucleic acid in plants; increase photosynthetic rate, increase the activity of peroxidase and nitrate reductase; increase the metabolism of carbon and nitrogen in plants, enhance the absorption of water and fertilizer, and regulate the water content of plants. Balance, thus improving the drought resistance and cold resistance of the plants.

9. Ethephon

This product is a growth regulator that promotes plant maturation. When ethephon enters the plant, it will release ethylene due to the PH size of the plant tissue, promote maturation, inhibit elongation, promote organ shedding, induce flower bud differentiation, and promote germination. Promote the occurrence of adventitious roots and so on.

It is very stable in acid medium, and above pH 4, it decomposes and releases ethylene. After entering the plant through the leaves, bark, fruit or seeds of the plant, and then transmitting it to the active part, it releases the ethylene, which can play the physiological function of endogenous hormone ethylene, such as promoting cotton maturation and Leaf detachment, dwarf plants, changing the ratio of male and female flowers, and promoting the early characteristics of cotton boll opening and bubbling.
