Problems solved by technology

Judging from the use in the past 30 years, jujube farmers increase the number of sprays to increase fruit setting under high temperature, drought and no rain weather, resulting in a large number of jujube fruit setting in the early stage, excessive nutrition consumed by the tree body, and young fruit in the later stage.

Embodiment 1

[0018] The jujube flower preservation and fruit setting agent is made of the following raw materials: 4.5kg of sodium tetraborate decahydrate, 3.0kg of a-naphthaleneacetic acid, 350kg of water, 6.0kg of urea, 33kg of sodium nitrophenolate, and 26.5kg of fulvic acid.

[0019] Preparation method: heat the water to 70°C and keep the temperature constant, dissolve the mixed powder of a-naphthaleneacetic acid and sodium tetraborate decahydrate, stir continuously until the reaction is complete, and the crystal powder is completely dissolved, and the temperature of the liquid is cooled to 40-45°C When the temperature is high, dissolve urea into it, then let it cool to 20-25°C, dissolve sodium nitrophenolate in the solvent, stir evenly, and finally add fulvic acid in stages, stir evenly, and this jujube tree preserves flowers and sets fruit finished product.

[0020] How to use: Spray on jujube trees. In the full flowering stage, within 1 to 4 days after the jujube tree opens its nai...

Embodiment 2

[0028] The jujube flower preservation and fruit setting agent is made of the following raw materials: 3.0kg sodium tetraborate decahydrate, 4.0kg a-naphthalene acetic acid, 300kg water, 7.0kg urea, 9.0kg sodium nitrophenolate, and 15kg fulvic acid.

[0029] Preparation method: heat the water to 60°C and keep the temperature constant, dissolve the mixed powder of a-naphthaleneacetic acid and sodium tetraborate decahydrate, stir continuously until the reaction is complete, and after the crystal powder is completely dissolved, wait for the liquid to cool down to 40-45°C When the temperature is high, dissolve urea into it, then let it cool to 20-25°C, dissolve sodium nitrophenolate in the solvent, stir evenly, and finally add fulvic acid in stages, stir evenly, and this jujube tree preserves flowers and sets fruit finished product.

[0030] How to use: Spray on jujube trees. In the full flowering stage, within 1 to 4 days after the jujube tree opens its nails, take 15 ml of this ...

Embodiment 3

[0037] Jujube flower preservation and fruit setting agent is made of the following raw materials: sodium tetraborate decahydrate 5.0kg, a-naphthalene acetic acid 2.0kg, water 500kg, urea 8.0kg, sodium nitrophenolate 20kg, foliar surfactant: alkyl poly Oxyethylene ether 8.0kg.

[0038] Preparation method: heat the water to 80°C and keep the temperature constant, dissolve the mixed powder of a-naphthaleneacetic acid and sodium tetraborate decahydrate, and keep stirring until the reaction is complete, and the crystal powder is completely dissolved, and the temperature of the liquid is cooled to 40-45°C Dissolve urea in it, then let it cool to 20-25°C, dissolve sodium nitrophenolate in the solvent, stir evenly, and finally add alkyl polyoxyethylene ether, stir evenly to obtain the jujube tree protection The finished flower and fruit setting agent.

[0039] How to use: Spray on jujube trees. In the full flowering stage, within 1 to 4 days after the jujube tree opens its nails, ta...

Abstract

The invention discloses a jujube flower-retention fruit-setting agent and preparation method thereof, which is prepared by adopting the materials of the following weight portions: 3.0 to 6.0 portions of sodium borate, 2.0 to 4.0 portions of Alpha-naphthylacetic acid, 200 to 500 portions of water, 4.0 to 8.0 portoins of carbamide, 9.0 to 56.5 portions of sodium nitrophenolate as well as 8 to 45 portions of leaf-surface active agent. The jujube flower-retention fruit-setting agent has rational medicament compatibility, can greatly improve the fruit-setting rate of jujube under high temperature and drought climate, can effectively prevent flower and fruit from dropping, can improve the fruit-setting rate to 96.8%, reaches a drop-preventing rate as high as 82 percent above; the quality of the jujube growing after spraying the agent is good; moreover, the agent can obviously promote growth of young fruits. The jujube flower-retention fruit-setting agent has low production cost, and is convenient to be used.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a flower-preserving and fruit-setting agent for jujube trees and a preparation method thereof. Background technique [0002] Jujube is a multi-flowered tree species, but affected by tree nutrition and environmental conditions, the phenomenon of flower and fruit drop is very serious, and the natural fruit setting rate is only about 1%. For jujube flower pollination and pollen germination, the most suitable meteorological conditions are temperature 24°C-26°C, relative air humidity 70%-80%; humidity is too low, pollen development is poor, such as the pollen relative humidity of jujube jujube At 40%, almost no germination. Jujube trees are in the flowering and fruit-setting period, and the jujube regions in northern my country are generally in the dry season, with high temperature and low air relative humidity. This kind of weather is extremely unfavorable for jujube fruit-setting. For t...
