Fruit trees require proper care for high yields and quality fruits. Flower and fruit protection is crucial in the cultivation process, and growers can use medicines to promote fruit setting, making flower and fruit protection easier. So, what is the best medicine for flower and fruit protection? Let's find out together.
1. Gibberellins
Gibberellins are efficient, non-toxic, broad-spectrum plant growth regulators with strong permeability and rapid absorption. They promote root growth, enhance flowering and fruit setting, increase plant nutrient uptake, facilitate fertilization, and improve photosynthetic efficiency at low concentrations. Additionally, gibberellins enhance plant resistance to drought, cold, and salinity, reduce disease incidence, and alleviate phytotoxicity.
2. Sodium Naphthaleneacetate
Sodium naphthaleneacetate is a broad-spectrum, efficient, low-toxicity plant growth regulator. It rapidly promotes cell division and expansion, stimulates root formation, flowering, and budding, regulates growth, accelerates maturation, prevents flower and fruit drop, and increases yield. It also enhances plant resistance to cold, diseases, drought, heat, and salinity.
3. Gibberellin
There are numerous types of gibberellins, with at least 38 known varieties. They belong to the diterpene acid class of plant hormones and have widespread application in agriculture. Gibberellins stimulate leaf and shoot growth, effectively increasing yields.
4. Cytokinins
Cytokinins are plant hormones that regulate cell growth and development. They are isolated from maize or other plants or synthesized artificially. Cytokinins primarily function at the plant's roots, promoting the differentiation and growth of various tissues, synergizing with auxins.
5. Potassium Dihydrogen Phosphate
Potassium dihydrogen phosphate is a high-concentration, chloride-free potassium fertilizer with low salinity and high nutrient content, suitable for use on various crops. It promotes fruit expansion, ripening, and metabolic activity in crops, as well as enhances root growth and improves resistance to freezing, adverse conditions.
6. Amino Acid Esters
Amino acid esters enhance plant absorption of water and nutrients, accumulation of dry matter, regulation of water balance, delay of plant aging, promotion of early ripening, yield increase, and quality improvement. Application during the flowering period, mid-fruit drop period, and when fruits reach 3-5 cm in size can accelerate fruit enlargement, increase fruit setting rate, and enhance cold and disease resistance.
Conclusion
These are some of the best medicines for flower and fruit protection. There are many options available, and growers should choose the most suitable ones based on their crops. It's essential to understand the proper application methods and precautions when using these medicines for flower and fruit protection.
Frequently Asked Questions (FAQ)
1. How can I tell if my fruit trees need flower and fruit protection?
If your fruit trees are not setting fruit properly or if the fruit quality is poor, it may indicate a need for flower and fruit protection. Look for signs such as low fruit yield, misshapen or damaged fruits, and pest or disease infestations.
2. When is the best time to apply flower and fruit protection medicine?
The best time to apply flower and fruit protection medicine is during the flowering and fruit setting stages of the crop. This is typically in the early to mid-growing season, depending on the specific crop and local climate conditions.
3. Are there any risks associated with using flower and fruit protection medicines?
While flower and fruit protection medicines can be beneficial for crop production, there are some potential risks to be aware of. These may include phytotoxicity, environmental contamination, and residues in the harvested fruits. It's essential to follow the recommended application rates and safety guidelines provided by the manufacturer.
4. Can flower and fruit protection medicines be used in organic farming?
Some flower and fruit protection medicines may be approved for use in organic farming, while others may not meet organic certification standards. It's essential to check the specific regulations and requirements of organic certification programs in your region before using any agricultural inputs.
5. How long does it take to see results after applying flower and fruit protection medicine?
The time it takes to see results after applying flower and fruit protection medicine can vary depending on factors such as the type of medicine used, the crop species, and environmental conditions. In general, you may start to see improvements in fruit set and quality within a few weeks to months after application.
