Application of Plant growth regulators in Flower planting

Growth regulators can control the synthesis or metabolism of hormones in flowers and plants, change the distribution of assimilates, regulate the growth and development of flowers, and their effects can make flower stems thick and short, leaves dark green and leaves thicker. Due to the inhibition of stem growth, the competition for nutrients during flower bud germination is reduced, so flowers can blossom earlier. Growth inhibitors are usually applied to Huawang 3, and can be used to control shoot growth, expand fruit, strengthen roots and stems, and optimize quality in tobacco, vegetables, peppers, flowers, medicinal herbs, melons, peaches and other fruit trees. Generally, 16 tablets per bottle, 15 kg of water per grain, sprayed once every 7-10 days, and sprayed 2-3 times during the growing period, can assimilate the transmembrane signal conversion of plant cells, forcing the top tip exuberant nutrition to return a large amount, and the inertia advantage of punching tip quickly weakens to the capping situation.

Ingenious application of plant growth regulators to promote the healthy growth of flowers. The application of plant growth regulators in flower production can not only promote flower growth, control plant type, induce flowering and fruit, prevent flower disease and shedding, but also significantly improve planting efficiency. The specific usage of it is introduced as follows:

Promoting growth 1. Soaking the base of cuttings such as poinsettia and tea trees with a concentration of 5000 mg-10000 mg / L Bijiu (also known as hydrazide, B9) solution can promote rooting and improve the survival rate of cuttings. 2. Soaking seeds with gibberellin solution with a concentration of 50 mg-200 mg / L can promote seed germination and growth. 3. When cutting, the base of rose branches with a length of 6 cm-8 cm was soaked in naphthalene acetic acid solution with a concentration of 100 mg-150 mg / L, which could induce rooting. Controlling plant type 1. Spraying chrysanthemum stems and leaves with high concentration of ethephon solution of 1000 mg / L can effectively inhibit Internode elongation and flower bud development. 2. Watering the soil with 500 mg / L paclobutrazol solution can make the rhododendron plant dwarf, compact and increase the crown, and spray chrysanthemum evenly with 100-150 mg / L paclobutrazol solution to dwarf the plant. 3. In the early growth stage of rhododendron, the plant could be dwarfed by watering the soil with the concentration of 2000-10000 mg / L, and the leaves were evenly sprayed with 1000-1500 mg / L solution about 10 days after flowering, which could promote the dwarfing of the plant and make the bulb enlarged. 4. Soaking the chrysanthemum cuttings with 3000 mg / L Bijiu solution or spraying the whole chrysanthemum plant evenly twice 1-2 weeks after transplanting (7-10 days interval each time) can make the chrysanthemum plant dwarf and increase the flower size. Induced flowering and fruiting 1. Soaking the bulb of Iris bulb with ethephon solution of 500-1000 mg / L for 12-24 hours can break the dormancy of seed bulb and promote early budding and flowering. African chrysanthemum and marigold treated with ethephon can bloom ahead of time, while lilies growing in greenhouse can bloom one week earlier when treated with 10 mg / L ethephon solution. After the begonia, emerald chrysanthemum and marigold were treated with ethephon solution, the number of flower buds of begonia was inhibited and decreased, while the flowering number of emerald chrysanthemum and marigold increased significantly. The treatment of ornamental fruit flowers with 100 mg / L ethephon solution can increase the fruit setting rate and accelerate the fruit ripening. 2. Spraying paclobutrazol solution with concentration of 300-500 mg / L on flower plants can promote flower bud differentiation. The uniform spraying of paclobutrazol solution with the concentration of 400-500 mg / L on ornamental fruits and flowers can obviously increase the fruit setting rate. 3. The flowering function of chrysanthemum plants can be enhanced by uniform spraying with gibberellin solution of 1000 mg / L. Using gibberellin solution with a concentration of 1-5 mg / L to spray evenly before cyclamen flowering can promote flowering. 4. Spraying pineapple leaves with 5-10 mg / L naphthylacetic acid solution can make pineapple blossom earlier. Spraying evenly on the surface of ornamental fruits and flowers with 50-100 mg / L naphthylacetic acid solution can delay the ripening of fruits and prolong the ornamental period of flowers and fruits. Preventing flower disease and shedding 1. Spraying tulip seedlings evenly with gibberellin solution with a concentration of 300-400 mg / L can not only promote its early flowering, but also make it form anthocyanin earlier and prevent the occurrence of flower blast. 2. Spraying the flowers and leaves evenly with 50 mg / L naphthylacetic acid in the first 7 days before the flowers appear on the market can reduce the natural shedding of flowers and bracts under high temperature and low lighting conditions. 3. In the late autumn growing season, young citrus trees are sprayed evenly on the crown with a concentration of 1000-2000 mg / L of dwarfin solution mixed with 1% 2% calcium chloride solution, which can enhance the cold resistance of young citrus trees. When the flower buds of peach blossoms are blooming, the cold resistance and stress resistance of peach buds can be enhanced by uniform spraying with a solution of 100-1000 mg / L. The three major effects of plant growth regulators on flowers the application of plant growth regulators in flower production can not only promote flower growth, control plant shape, induce flowering, prevent flower disease and shedding, but also significantly improve planting efficiency. Effect 1: promote growth 1, soak the base of cuttings such as poinsettia and tea trees with a concentration of 5000-10000 mg / L Bijiu (also known as hydrazide, B9) solution, which can promote growth and improve the survival rate of cuttings. 2. Soaking seeds with gibberellin solution with a concentration of 50-200 mg / L can promote seed germination and growth. 3. When cutting, rooting can be induced by soaking the base of rose branches with a length of 6-8 cm in 100-150 mg / L NAA solution. Effect 2: control plant shape 1. Spraying chrysanthemum stems and leaves with high concentration of ethephon solution of 1000 mg / L can effectively inhibit Internode elongation and flower bud development. 2. Watering the soil with 500 mg / L paclobutrazol solution can make the rhododendron plant dwarf, compact and increase the crown, and spray chrysanthemum evenly with 100-150 mg / L paclobutrazol solution to dwarf the plant. 3. In the early growth stage of rhododendron, the plant could be dwarfed by watering the soil with the concentration of 2000-10000 mg / L, and the leaves were evenly sprayed with 1000-1500 mg / L solution about 10 days after flowering, which could promote the dwarfing of the plant and make the bulb enlarged. 4. Soaking chrysanthemum cuttings with 3000 mg / L Bijiu solution or spraying the whole chrysanthemum plant twice (7-10 days interval) 1-2 weeks after transplanting can promote the dwarfing of chrysanthemum plants and the increase of flowers. Effect 3: inducing flowering and fruiting 1. Soaking the bulb of Iris bulb with ethephon solution of 500-1000 mg / L for 12-24 hours can break the dormancy of seed bulb and promote early budding and flowering; African chrysanthemum and marigold treated with ethephon can bloom ahead of schedule; lily plants growing in greenhouse can bloom one week earlier with ethephon solution at the concentration of 10 mg / liter. After Begonia, Cuiju and marigold were treated with ethephon solution, the number of flower buds of begonia was inhibited and decreased, while the number of flowering of emerald chrysanthemum and marigold increased significantly, and the treatment of ornamental fruit flowers with 100 mg / L ethephon solution could increase the fruit setting rate and accelerate the fruit ripening. 2. Spraying flower plants with 300-500 mg / L paclobutrazol solution can promote flower bud differentiation, and spraying ornamental fruit flowers with 400-500 mg / L paclobutrazol solution can obviously increase the rate of fruit setting.
