Fruit safety Fruit pollution-free medication is the key. The use of highly toxic, highly toxic, and high-residue pesticides in orchards is forbidden; the use of biological pesticides and low-toxicity, low-residue pesticides in orchards is encouraged, and safe fruit products that are pollution-free are produced.
P-chlorophenoxyacetic acid, also known as anti-dropping element, protects fruit spirit, tomato spirit, P51, promotes growth.
First, the role of features
1. Anti-drugs are currently widely used in domestic absorption, broad-spectrum, high-efficiency, multi-functional plant growth regulators, which can effectively inhibit the formation of abscisic acid in crops, so that separation between layers is not easy to produce, so effectively Reduce fruit loss and increase production.
2. Baoguo Ling is a low-toxicity plant growth regulator. It is low-toxic to humans, livestock and fish. It has no accumulation and no "triple effect". It is safe for crops and fruit trees.
Second, the type of preparation
1. Anti-dropping agent 95% wettable powder.
2. Baoguo Ling 1% water agent.
3. Tomato Ling 1% EC.
Third, the role of objects: can effectively prevent the loss of flowers and fruits, accelerate the development of young fruit, the formation of seedless fruit; can promote seed germination, early delivery, increase chlorophyll content, accelerate crop growth, promote seed, fruit hypertrophy, increase weight and retention, Steady fruit, prevent falling off, mature earlier, improve quality. After applying on citrus, grape, apple and other fruit trees, the yield increase effect is significant.
Fourth, application technology
1. Orange tree.
1 After Xiehua and the first and second physiological fruit drop, use 1% anti-dropping agent 250 ~ 400 times liquid, spray each time, can increase the fruit setting rate, early maturity, increase production.
2 Before harvesting fruit, use 1% anti-dropping agent 250 ~ 400 times liquid, spray 1 ~ 2 times, can prevent pre-harvest fruit drop, reduce wind damage, salt damage, fallen leaves.
2. Litchi tree: In the full flowering period and the initial stage of physiological fruit drop, use 1% anti-dropping agent 400 times liquid and 300 times liquid, respectively, each spray 1, can increase the fruit setting rate, increase production.
3. Apple trees: In the flowering stage, growth period before fruit drop and 30 days before harvest, 100 ml of 1% anti-dropping agent, 25 to 30 kg of water, and 1 spray each can increase fruit setting rate and enhance color. Improve quality.
4. Grape vines.
1 Spraying was conducted between 5 days before flowering and 10 days after flowering with a mixture of 15 mg/kg of rhein (active ingredient) and gibberellin (active ingredient) at a concentration of 40 ml/kg. Seedless fruit can be induced to increase yield.
2 At the beginning of full bloom, with a concentration of 10-30 ml/kg of the active ingredient solution, spraying once every 15 days, spraying 3 times continuously, the growth of auxiliary shoots can be significantly inhibited, and the chlorophyll content of the leaves can be increased. It is conducive to thickening new shoots, increasing tree vigor, increasing fruit setting rate, single fruit weight, fruit sugar content, and coloring index.
5. Jujube tree: Jinsi jujube harvested 4 weeks before, with the concentration of 10 ~ 20 ml / kg of anti-dropping agent (active ingredient) solution spray, can significantly reduce the gold jujube preharvest fruit drop.
V. Precautions
1. Use strictly in accordance with the prescribed concentration, which is safe for crops and fruit trees, otherwise it is easy to produce phytotoxicity. The common symptom is the distorted growth of plant leaves.
2. When anti-dropping agent powder is dispensed, dissolve the powder with a small amount of hot water first, and then add the amount of water in accordance with the concentration of use; when adding an appropriate amount of urea and potassium dihydrogen phosphate, the effect will be better, but be ready for use.
3. Anti-dropping spray should be selected on a cloudy or sunny afternoon, in order to evenly wet the degree, do not repeat the spraying, otherwise it is easy to cause injury; if the drug within 12 hours after the rain, need to re-spray.
4. Pay attention to the application of the anti-dropping chemicals to crops. It should be promoted on a large scale based on community experiments.
5. In the dark environment, it can be stored for a long time.
