【11】Features

Phenylpeptidamic acid is a biologically active plant growth regulator. It can quickly penetrate into plants through foliar spraying, promote the delivery of nutrients to the growth point of flower buds, enhance plant cell vitality, promote chlorophyll synthesis, and facilitate fertilization. Pollination has the effect of inducing flower buds into flowers and fruiting. To prevent physiological and pre-harvest fruit drop, the natural ripening period can be advanced 5 to 7 days. It has obvious effect on flower and fruit preservation, and can increase the yield of crops with low fruit setting rate.

【12】Applied technology

Soybean

Spraying 500-740mg/L panpan industry’s phenylpeptidic acid on the leaves of soybeans at the full blooming and podding stages respectively can promote their growth and development, prevent flowers and fruits from falling off, make the beans plump, increase the 100-grain weight, and advance the maturity period. .

Chili

Spraying 200mg/L panpan industry’s phenylpeptidamic acid liquid three times at the seedling stage, budding stage and early flowering stage of pepper can induce the enhancement of stress resistance of pepper, and has a certain yield increasing effect.

Dates

In the flowering stage and young fruit stage, spraying 150-200 mg/L phenylpeptidic acid liquid for 1-2 times can promote the fruit setting of jujubes, adjust the stubbleness of the fruit stalk, reduce the physiological fruit drop, and increase the number of cells. Effective expansion of fruit.

Apple

Spraying with panpan industry’s 166.7mg/L phenylpeptide solution in the blooming period of apple center can prevent frost, promote flowers and preserve fruits, and prevent mildew heart disease; use 200mg/L phenylpeptide after flowering or before bagging Amino acid combined with mancozeb or prosenzin and other fungicides spray treatment can improve fruit set rate, prevent spot disease and brown spot disease, and accumulate nutrients for fruit growth and development; after apples are bagged, spray 250mg/L phenylpeptide Amino acid liquid is conducive to the accumulation of fruit nutrients and reduces fruit drop in the late growth stage.

【13】Notes

① Pay attention to reasonable fertilizer and water measures, and it should be used with caution in thin fields and dry and water-deficient areas.

②Due to the increase in flowering and fruiting, attention should be paid to the follow-up of nutrient fertilizers.

③ Avoid spraying under the hot sun. If it rains within 3 hours after spraying, it needs to be sprayed again.
