Advantages of Plant Growth Regulators

Plant growth regulators are widely used and can be used for cutting seedlings, or for dipping or soaking roots, in addition to many other uses. So what are the advantages of specific plant growth regulators? Let’s learn more about it below.

1. Promote crop growth

Spraying plant growth regulators in the early stages of crop growth can promote crop germination, accelerate branch and leaf growth, and make the crops lush and leafy.

2. Control dormancy and budding

In order to extend the storage period or sow in advance, growth regulators are needed to adjust or control. When the potatoes are about to be harvested, in order to prevent them from sprouting during storage, you can spray the stems and leaves with cyanamide 2-3 weeks before harvest to inhibit it. You can also spray naphthaleneacetic acid on paper scraps and mix them with potatoes for storage to inhibit sprouting.

3. Prevent flowers and fruits from falling

Some fruit trees, such as tomatoes , Solanaceae vegetables , beans and melon vegetables, often experience a large number of flowers and fruits falling due to temperature discomfort and drought, which has a great impact on yield. At this time, you can spray some anti-fall agents, 2.4-D and other growth regulators to prevent flowers and fruits from falling.

4. Add sugar

For crops such as citrus, apple, pear, grape, watermelon, and sugarcane, spraying in the middle and late stages of fruit setting can promote the conversion and storage of sugar and improve the quality and yield of the fruit.

5. Improve photosynthesis capacity

Spraying plant growth regulators on crops can enhance the metabolism and photosynthesis capacity of crops, accelerate the absorption, circulation and storage of nutrients by crops, thereby achieving the goal of promoting high-quality and high-yield crops.

6. Increase production

Plant growth regulators can promote or inhibit the growth of certain organs of the plant, thereby improving yield and quality. Cultivated celery can be sprayed with gibberellin 15-30 days before harvest to increase its height, increase the number of leaves, make its texture soft and tender, and increase yield.

7. Promote maturity

During the color change period of tomatoes, apply ethephon on the fruit surface before picking. It can advance their maturity by about a week and increase early yield. It is necessary to harvest ripe red peppers. In the later stage of their fruit growth, when some peppers begin to turn red, you can spray a little ethephon to promote them to turn red and harvest them early.

8. Fresh-keeping effect

Many vegetables easily wilt, change color and age after harvesting. You can spray a little benzylaminopurine solution on them before harvesting to preserve freshness and prolong storage time.

That’s it
