Rhododendron: Spray the whole plant with 1000 mg/L liquid medicine every week 1 time for about 5 times until the flower buds develop well, which can prolong the flowering period by 35 days. For rhododendrons that need low temperature to break dormancy, GA4+7 can replace low temperature to break dormancy of rhododendrons, and can maintain the quality of flowers, increase the diameter of flowers and maintain the original petal color.
Cucumber: In order to cultivate all-female cucumber hybrids, it is necessary to have enough male flowers to provide energetic pollen. When the first true leaf of all-female cucumber seedlings is fully unfolded, the seedlings are sprayed with 1 000 mg/L chemical solution for three times in1week to induce the development of male flowers, provide pollen for untreated female plants, and make parthenocarpy cucumbers cross.
After being compounded with different plant growth regulators, GA4+7 was sprayed on pears, sweet cherries, strawberries, bananas, fruits and vegetables in the greenhouse to improve the quality and increase the yield.
GA4+7 is the main effective component of apple-like protein (Plomarin) and a homologue of gibberellin GA3. It is mainly used for thinning apples, changing the shape and size of apples, increasing the weight of a single fruit and thickening the peel, thus prolonging the shelf life. Apple plasticizer can not only improve the fruit shape characteristics of Marshal apple, but also make the pentagonal protrusion at the end of calyx obvious and the fruit shape index significantly improved, thus effectively improving the quality of Red Star and Starkrimson apples, and also improving the appearance quality and fruit shape index of domestic Red Fuji.
Usage: use 3.6% apple plasticine 100 ml once per mu, directly dilute it with water by 600 ~ 1200 times, spray it for the second time in full bloom of apples, and spray it again after 10 days.
The sterile seeds of cotton and other crops treated with this product increase, so it is not suitable to use pesticides.
