Forchlorfenuron（cppu） is a new type of plant growth regulator with cytokinin activity, which can promote cell division, differentiation, organ formation, protein synthesis, and improve photosynthesis. The practical technology of Forchlorfenuron（cppu） is now introduced as follows:
Practical technology:
Melon and cucumber: 0.5-1kg per 10g of water at 10-16°C, 1-1.5kg per 10g of water at 17-25°C, 1-1.5kg per 10g at 26-30°C Stir 1.5-2kg of water into a homogeneous solution. Dip the melon fetus or spray the melon fetus evenly with a micro-sprayer. After the application, the melon rate reaches 98%-100%, and the young melon grows fast, the melon is large, and the quality is high, and it will be marketed early.
Watermelon: On the day when the female flower blooms or 1 day before and after, spray the melon fetus with a sprayer or apply 20-33 times of 0.1% soluble liquid to the fruit stalk for 1 circle, which can prevent the watermelon from growing too vigorously and without insect pollination. It can improve the fruit setting rate and yield, and increase the sugar content. This method also works for melons.
Peppers, tomatoes, eggplants, zucchini: soak young fruits with 5-15mg/kg liquid medicine after the flowering stage, which can improve the fruit set rate, expand the fruit and increase the yield.
Grape: 10-15d after blooming, dipping young fruit with 0.1% soluble liquid 10-100 times liquid can improve fruit setting rate, increase the weight of single fruit, make the fruit swell, gain weight, and increase the content of soluble solids. Using 3-5mg/kg liquid medicine to soak the ear or spray the ear with 3-5mg/kg liquid 14-18d before blooming and 10-15d after blooming can make the fruit expand and increase the yield by more than 80%.
Kyoho, rattan, etc.: 1-1.5 kg of water per 10 mL, soak (or evenly spray) the ear about 15 days after full bloom, and the fruit with seeds (20-40%) and seedless fruits (without seeds) will increase significantly. It is 1-3 times as high as nuclei white, Venus seedless, etc., with compact fruit shape and good commerciality; for varieties (such as Kyoho) with severe flower and fruit drop and sensitive to climatic conditions during the flowering period (such as Kyoho), the effect of promoting fruit setting is very significant, which greatly increases the yield.
Tobacco: Increase new buds, accelerate the formation of buds, and at the same time promote the growth function of stems, leaves, roots and fruits, make leaves hypertrophy and increase yield.
Apple, citrus, peach, pear, plum, lychee, longan: use 5-20mg/kg to soak the fruit stem 10d after full bloom and spray young fruit, which can promote coloring, improve fruit set rate, increase fruit size, and increase yield.
Navel orange: Before the physiological fruit drop, that is, 25-30 days after the flower withers away, spray the canopy and fruit stems with 50-200 times of 0.1% soluble liquid solution twice, which can significantly improve the fruit set rate, prevent fruit drop, and accelerate fruit growth.
Kiwifruit: soak the young fruit with 5-10mg/kg liquid medicine 20-25d after blooming, spray twice with 10ppm on the 21st day of falling flowers, the fruit can be puffed by 30-100%, the sugar content will increase by 1.4-2.7%, and the Vc content will increase by 16.4- 24.6%, and the weight of single fruit increased by 50%. It can enlarge the fruit and increase the weight of the single fruit without affecting the quality of the fruit.
Loquat: When the diameter of the young fruit is 1 cm, soak the young fruit with 100 times of 0.1% soluble liquid solution, and then soak the fruit again after 1 month. After the fruit is frozen, apply medicine in time to promote the expansion of the fruit.
Tangerine: Use 0.5mg/kg of liquid medicine once in full bloom, and spray the crown once at the end of fruit setting and fruit drop to improve the fruit setting rate.
Hawthorn: Spraying with 10mg/kg liquid in full bloom period can improve fruit set rate, expand fruit and increase single fruit weight.
Li: Spraying with 5mg/kg liquid 10d after flowering can increase the weight of single fruit and increase yield.
Cherries: spray with 5mg/kg liquid in full bloom to improve fruit set rate, expand fruit and increase yield.
Peanut: spraying with 1mg/kg at the pod setting stage can increase chlorophyll, increase the number of pods and fruit. Guangdong spring peanut Yueyou 116 during the pod setting period, spraying the peanut leaf surface with a concentration of 1mg/L Forchlorfenuron（cppu） solution can increase the leaf thickness, chlorophyll content and light rate, and increase the pod setting rate, full fruit rate and 100 kernel weight. , the yield per plant increased by about 12.6%.
Potato: spraying with 100mg/kg liquid medicine 70 days after planting can significantly increase the yield.
Rice: Use 15 mg/kg liquid to spray 10 days after full heading, which can keep green, promote reproductive growth, develop root system and increase yield.
Strawberry: After picking, spray or soak the fruit with 0.1% soluble liquid 100 times, dry and store it, which can prolong the storage period.
Cucumber: In order to solve the problem of "melting melon" under the conditions of insufficient low temperature and light and poor flowering and fertilization, apply 0.1% soluble liquid 20 times to the handle of the melon one day before or on the day of flowering, which can improve the fruit setting rate, promote the results, and make the cucumber more suitable. Uniform fruit size increases yield and improves quality.
Cherry radish: spray 20 times of 0.1% soluble liquid at the 6-leaf stage, which can shorten the growth period and increase the yield.
White radish with expanded fruit: Use 5mg/kg liquid medicine to spray the foliar surface of the fleshy roots at the beginning of the expansion period, spray once every 4 days, a total of 4 times, which can inhibit the chaff and bolting of the radish in the greenhouse in spring and increase the yield.
Soybean: spray 0.1% soluble liquid 10-20 times (50-100mg/L) at the beginning of flowering, which can improve photosynthesis, increase protein content, and increase yield. Spraying with 1mg/kg liquid medicine in the pod setting stage can promote reproductive growth and increase yield.
Sunflower: Spray 0.1% soluble liquid 20 times during the flowering period, which can make the grain plump and increase the grain weight and yield.
Barley and wheat: Spray flag leaves with 67 times of 0.1% soluble liquid to increase yield. Spraying with 1mg/kg liquid medicine 10d after full heading and at flowering stage can promote reproductive growth and increase yield.
