In production, due to environmental conditions or poor operation and management, a large number of flowers and fruits often fall off, the fruit is poorly developed, the commercial quality is reduced, and the benefits are poor. Preserving flowers and fruits and promoting the transfer of nutrients to fruits are the most critical management measures to obtain high yield and quality. In production, there are many agents that preserve flowers and fruits and promote fruit enlargement, some of which are not effective and some have great side effects. Today, I would like to recommend a fruit-enlarging formula with good safety and significant effect.
1. Formula combination
The fruit-enlarging formula is chlorfenapyr · brassinolide, which is a plant growth regulator made by mixing chlorfenapyr + brassinolide in a certain proportion. This formula can not only promote the rapid enlargement of fruits, but also promote plant growth, and has a promoting effect on the lateral and longitudinal growth of fruit organs, thereby playing a role in enlarging fruits.
Chlorfenapyr is a plant growth regulator that promotes cell division. Its activity is 100 times higher than that of cytokinins. Under extremely low concentration conditions, it can accelerate cell mitosis, promote cell enlargement and differentiation, rapidly expand fruits, and prevent fruit and flower shedding. It has a significant effect and is currently the most effective and widely used plant growth regulator.
Brassinolide is also a plant growth regulator with multiple functions. At very low concentrations, it can significantly increase the growth of plant nutrients and promote fertilization. It also has the effects of promoting cell division, fruit enlargement, improving fruit quality, and improving commercial properties.
2. Formula characteristics
(1) Improve fruit setting rate: This formula can promote the rapid division of fruit cells, inhibit the synthesis of abscisic acid, transport a large amount of nutrients to the fruit, and prevent flower and fruit falling. After use, the flower and fruit preservation rate can basically reach 100%.
(2) Promote fruit enlargement: After use, this formula can accelerate cell division in the fruit and promote rapid fruit enlargement. According to experiments, the fruit enlargement rate is increased by 60-100%.
(3) Improve fruit quality: After using this agent, it can significantly improve the photosynthesis capacity of leaves, synthesize more nutrients, accelerate the delivery of nutrients to fruits, and significantly increase the solid content of sugar, protein, amino acids, vitamins and other solids in fruits. The quality of fruits is significantly improved, and the commercial value is better.
(4) Good safety: Due to the addition of brassinolide, the safety of fruits treated with this formula is greatly improved, and the occurrence of cracked fruits, hollow fruits, deformed fruits, leaf deformities and other phenomena is effectively avoided.
(5) More widely applicable: This formula can be widely used in more than 100 crops such as wheat, rice, tomatoes, peppers, eggplants, peanuts, soybeans, cucumbers, watermelons, melons, apples, pears, mangoes, litchis, longans, kiwis, cherries, walnuts, grapes, etc.
3. Applicable crops
This formula can be widely used in wheat, corn, cotton, rice, peanuts, soybeans, tomatoes, eggplants, peppers, cucumbers, watermelons, melons, tea, apples, hawthorns, pears, mangoes, litchis, longans, kiwis, grapes, walnuts, edible fungi and other crops.
4. Usage
(1) For watermelons and melons: On the day of female flower opening or 1-2 days before, use 30-40 times diluted 0.1% chlorfenapyr soluble solution + 2500-3000 times diluted 0.01% brassinolide soluble solution and evenly apply it around the melon stem to quickly promote the growth of young melons.
(2) For cucumbers: On the day of female flower opening or one day before. Use 60-100 times of 0.1% chlorfenapyr soluble solution + 2500-3000 times of 0.01% brassinolide soluble solution to dilute the solution and soak the melon embryos evenly once. After application, the fruit setting rate reaches 98%-100%, and the young melons grow fast, are large, of high quality, and are put on the market earlier.
(3) Use for grapes: About 15 days after the grapes have bloomed, use 50-100 times of 0.1% chlorfenapyr soluble solution + 3000-5000 times of 0.01% brassinolide soluble solution to dilute the solution and soak the grape bunches. The solution should immerse the entire bunch. It can promote the formation of seedless fruits, prevent the fruit from falling off, and make the fruit expand rapidly. Increase the yield by more than 80%.
(4) Use for kiwifruit: 20-25 days after flowering, use 50-200 times of 0.1% chlorfenapyr soluble solution + 3000-5000 times of 0.01% brassinolide soluble solution to dilute the solution and soak the young fruit. The fruit can swell by 30-100%, increase the sugar content by 1.4-2.7%, increase the vitamin C content by 16.4-24.6%, and increase the weight of each fruit by 50%. It can make the fruit swell and increase the weight of each fruit without affecting the quality of the fruit. Use 50-200 times of 0.1% chlorfenapyr soluble solution to soak the grape bunches, and soak the young fruit once with the diluted solution.
(5) Use for wheat: Spray the leaves once during the flowering and filling stages of wheat. Spray with a concentration of 3-5 ml/L + 2500-3000 times of 0.01% brassinolide soluble solution. Generally, the yield can be increased by about 10%.
