10. Functional characteristics: Butyryl hydrazide can inhibit the growth of plants, promote short stature or control the growth of branches and leaves, improve the stem height and shape of the plants, make the leaves green, small and thick, compact and thick, with developed roots and increased root dry weight. Reduce the proportion of crown roots and increase the ability to withstand cold and cold. Prevent falling flowers and fruit, promote the increase of results, improve fruit quality, hardness and fruit setting rate, and promote fruit ripening.
11. Using technology
(1) Promote rooting and increase survival rate
The sweet potato seedlings are immersed in 2 500 mg/L liquid for 5-8 minutes before transplanting, which can promote rooting and increase survival rate.
Dahlia, geranium, chrysanthemum, poinsettia, Dianthus, tea tree, etc. soaking the base of the cuttings with 1 000~5 000 mg/L liquid for 30 s can promote rooting and increase the survival rate of cuttings.
(2) Suppressing the length of the child and promoting the crop
After 7~14 days of transplanting the chrysanthemum, spray 3~3 times with 3 000mg/L liquid, which can promote dwarf and promote flower growth.
21 days after the flowering of the apple, the whole plant was sprayed once with a concentration of 1 000 to 2 000 mg/L. 45~60d before harvesting, the whole plant can be sprayed once with the concentration of 2 000~4 000mg/L, which can inhibit the growth of new shoots.
When the grape shoots are 6~7 leaves, the whole plant can be sprayed once with the concentration of 1 000~2 000mg/L, which can inhibit the new shoots.
At the beginning of the peanut needle, the whole plant is sprayed once with 3 000mg/L of liquid medicine, which can dwarf the plant shape and increase production.
When the tomato 1 leaf and 4 leaves are sprayed once with 2 500 mg/L of the drug solution, the growth of the stem and leaf can be inhibited.
In the initial stage of flowering, the whole plant is sprayed once with 3 000mg/L of liquid medicine, which can inhibit the length of the stem and increase the tuber.
During the panicle differentiation stage of rice, the concentration of 4 000~7 000 mg / L liquid leaf spray can promote dwarfing, lodging resistance and increase cold tolerance.
(3) Promote the development of roots and promote the growth of underground parts
Ginseng is sprayed once with 2 000~3 000mg/L of the drug solution to promote the growth of the underground part.
After the carrot is planted, it can be sprayed with a concentration of 500~1 000mg/L to promote the growth of fleshy roots or underground stems.
(4) Promote fruit setting, fall prevention, increase production
When the grape shoots are 6~7 leaves, the whole plant can be sprayed once with the concentration of 1 000~2 000mg/L to promote fruit setting.
After strawberry transplantation, spray 1~3 times with 1 000mg/L liquid to promote fruit setting and increase yield.
When the tomato 1 leaf and 4 leaves are sprayed once with 2 500 mg/L of the drug solution, the fruit setting can be promoted.
The pear trees were sprayed once every 1 day after the flowering and 21 days before the harvest, to prevent the young fruit from falling off and the fruit before harvest.
(5) Promote coloring and precocity
Before the peach fruit is matured, the fruit is sprayed once with the concentration of 1 000~2 000mg/L to promote coloration and promote early maturity.
After the cherry blossoms, spray once with 2 000~4 000mg/L of liquid medicine to promote coloration, early maturity and even fruit.
(6) Extended storage period
After harvesting, the grapes are immersed in the concentration of 1 000~2 000mg/L for 3~5min, which can prolong the storage period.
21d after the flowering of the apple, spray the whole plant with the concentration of 1 000~2 000mg/L once, or 45~60d before the harvest, and spray the whole plant with the concentration of 2 000~4 000mg/L for another time. The shelf life can be extended.
12. Notes
(1) The better the water and fertilizer conditions are, the more obvious the effect is. If the water and fertilizer conditions are seriously insufficient, the use will be severely reduced.
(2) The preparation may be used as needed, and if it is browned, it cannot be used.
(3) It can be mixed with a variety of pesticides but not with alkaline substances, oils and copper preparations. (Requires water soluble fertilizer formula can contact 13203809264)
