【11】Applied technology

1. Promote fruit setting and puffing, increase production and quality

Kiwi

20 to 25 days after blooming, dipping fruit with 5-20 mg L liquid medicine or evenly spraying fruit once can increase the weight of single fruit, enlarge fruit and increase yield.

Loquat

When the diameter of young loquat fruit is 1-1.5cm in diameter, the fruit is soaked once, and the concentration of use is 10-20mg/L; according to the situation, the fruit can be soaked again 30-45d after the first treatment, which can effectively promote the later growth of the fruit. Swelling, so that the quality of the fruit improves, early ripening market.

Grape

About 15d after blooming (the diameter of the fruit is 10-12mm), dipping the ear of the fruit once with 5-20mg/L liquid medicine can expand the fruit and increase the content of soluble solids.

watermelon

Spraying the melon fetus with 7.55-10mg/L liquid medicine on the day of female flowering or 1 day before flowering can significantly improve the fruit setting rate of watermelon, increase the sugar content of watermelon, improve quality and increase yield.

Melon

On the day of female flowering or 2 to 3 days before flowering, applying Panpan Industry’s 10-20 mg/L of medicinal solution to melon stems or spraying melon embryos can significantly improve the fruit setting rate of melons, increase the sugar content of melons, improve quality and increase yield.

cucumber

Under the conditions of poor flowering and fertilization such as low temperature, rain, and insufficient light during the flowering period, applying 5-20 mg/L of liquid medicine on the stalk or spraying the melon fetus on the day of flowering or 1 day before can improve the fruit setting rate and increase the yield.

Loofah

On the loofah varieties “Qiangfeng”, “Yucui” and “Thai loofah”, spraying 10 mg/L liquid on the ovary of the female flower on the day of flowering can significantly improve the loofah fruit setting rate, up to 97%; Improve loofah yield, and increase vitamin C and soluble sugar content.

navel orange

In the fruit expansion stage, apply 10-15mg/L liquid medicine to the honey dish of young fruit stalk once, which can promote the expansion of navel orange fruit and increase the yield.

strawberry

From 6 to 11 days after flowering, dipping fruit once with Panpan Industry’s 20mg/L liquid medicine can promote fruit enlargement and increase yield.

At the young fruit stage of bayberry, spraying with 10 mg/L liquid medicine once can increase the weight of single fruit, increase the content of total sugar and vitamin C, promote fruit expansion, and improve quality.

Peach

30d after flowering, spray young fruit with 10 ~ ~20 mg/L liquid medicine, which can expand fruit, increase yield and improve quality.

plum

In the flowering period or after flowering, spraying once with 5-10mg/L liquid medicine can improve the fruit setting rate.

Shatian pomelo

5d after full bloom, spray the young fruit evenly with 5-10mg/L liquid medicine, which can improve the fruit set rate, enlarge the fruit, increase the yield, and improve the quality.

Longan

20 ~ 30d after flowering, spray the young fruit with 20mg/L liquid medicine, which can enlarge the fruit, increase the yield and improve the quality.

mango

7~10d after flowering (the size of young fruit and peanut), spray the whole plant with 1~3mg/L liquid medicine or spray young fruit with 10~20mg/L liquid medicine, it is forbidden to use it within 1 month before harvest. It can be used 3 to 4 times during the whole growth period, with an interval of more than 10 days. Chlorfenuron treatment can promote fruit enlargement and increase the weight of a single fruit, but when the concentration is too high, the ratio of sugar to acid will decrease significantly, which will affect the quality.

Cherry

15d after the flowering period, evenly spraying with 5mg/L liquid can make the fruit increase, the single fruit weight increase, and promote the coloring.

Taiwan Green Dates

In the blooming period, 5mg/L of the liquid medicine is sprayed evenly on the flower ears, which can make the leaves turn green and thicken, promote fruit enlargement, and increase yield.

Tangerine

At 3-7 days after flowering and 25-35 days after flowering, 5mg/L chlorfenuron solution combined with 25-50mg/L gibberellic acid for key fruit spraying treatment can improve the fruit setting rate and avoid physiological fruit drop.

rice

Spraying with a concentration of 5-10mg/L at the heading stage can improve the rice milling rate, increase the 1000-grain weight and increase the yield.

wheat, barley

At the booting stage, foliar spraying with a concentration of 5-10 mg/L of the liquid can promote full grain and increase yield.

soybeans, beans

From the first flowering stage to the full flowering stage, the concentration of 1/L liquid spray can be used for foliar spraying, which can reduce the pods, increase the number of 3 fruits, promote the plumpness of soybean seeds, and increase the yield.

peanut

From the next needle stage to the pod setting stage, use the concentration of 1-5mg/L to spray on the leaves, which can improve the full fruit rate and increase the yield.

radish

When the fleshy roots swelled, the whole plant was sprayed 4 times with Panpan Industry’s 4 mg/L liquid medicine, with an interval of 10 days, which could prevent bolting and bran heart and increase the yield.

2. Preservation

Leafy vegetables

Spraying the whole plant with 1-2 mg L of medicinal liquid before picking can prevent the degradation of chlorophyll and prolong the fresh-keeping period of fresh products.

litchi

The green or reddish litchi small fruit (25-30mm in diameter) treated with 5-10mg/L chlorfenuron at the young fruit stage can delay the harvesting period by 14-21 days; and the color of the pericarp treated with chlorfenuron after harvesting is better than that of the litchi fruit. Red, the ratio of total soluble solids to titratable acid is greater than the control. At the same time, chlorfenuron treatment can reduce browning, slow down fruit decay and fading, and increase storage period.

mango

The senescence of postharvest mangoes can be effectively delayed after being soaked with 25mg/L chlorfenuron solution for 5 minutes and then stored at 25℃.

【12】Notes

①If the concentration is too high, it is easy to reduce the content of soluble solids, increase the acidity, slow down the coloring, and delay the ripening.

②Used on old, weak, diseased plants or weak branches without fruit thinning, the fruit expansion is not significant; to ensure the nutrients required for fruit expansion, the fruit should be properly thinned, and the amount of fruit should not be too much.

③Chlorfenapyr is used for fruit setting, mainly for flower and fruit treatment. The variety is very different, and the effect is affected by temperature and humidity. If you have no experience in using drugs for the first time, use this product for different purposes and new varieties, be sure to use this product before use. Consultation and small-area trial are successful before expanding use.

④The effect of mixed use of chlorimuron with gibberellic acid or auxin is better than that of single-use, but it must be tested before use under the guidance of professionals, and should not be used arbitrarily.

⑤ Re-spray in case of rain within 12 hours after treatment.
