Problems solved by technology

Preliminary research results show that potassium nitrate, lime nitrogen, cyanamide, gibberellic acid, etc. have certain effects on breaking dormancy and promoting maturity of fruit trees, but the difference is large, and the effect on promoting early maturity of fruit trees is not ideal

Embodiment 1

[0008] 1. The test was carried out in the northern solar greenhouse in July 2012. The test material was 2-year-old seedless white heart grapes. The row spacing was 2m×0.3m, and 1110 plants were planted per 670㎡. After the first batch of grapes were harvested, the tree body was rested for 35 days and pruned on July 28, leaving 4 to 10 buds on each fruiting mother branch. The test medicament is a sleep-destroying agent for fruit trees formulated with 50% cyanamide and 0.48% boron in parts by mass. When in use, 1500 times of must be added. Double liquid and water control, a total of 3 treatments, ready to use. Directly apply different concentrations of fruit tree sleep-destroying agents evenly on the top 2 bud eyes of the winter buds of the fruiting mother branches with a brush. The rest of the untreated winter buds were reserved for next year’s spring grape production. For each treatment, 96 plants were smeared, a total of 192 plants, 1344 buds were smeared, and water was used ...

Embodiment 2

[0014] 1. The experiment was set up in the American Zaohong No. 2 nectarine solar greenhouse in the north. The soil is sandy loam, with watering conditions and a high level of management. The solar greenhouse is 100 m long, with a span of 8.5 m and a ridge height of 3.6 m. The experimental tree variety was 6-year-old American Zaohong No. 2 nectarine, and the row spacing between plants was 1.5 m×2.0 m. A total of 250 plants were planted. The applied reagent is a sleep-destroying agent for fruit trees prepared from 50% cyanamide and 0.48% boron in parts by mass, and it is prepared by adding 1500 times of Bijia during use. Due to many previous experiments and observations, the concentration of 60 times the concentration of the fruit tree sleep breaker is obvious, so this test only sets the concentration of 60 times the concentration of the fruit tree sleep breaker aqueous solution, and sprayed water as a control. The number of treated plants is 200, the number of control plant...

Embodiment 3

[0019] 1. The experiment was set up in the sweet cherry solar greenhouse in the north. The soil is sandy loam, with watering conditions and a high level of management. The solar greenhouse is 50m long and has a span of 8m. The test tree was 8-year-old Hongdeng cherry, with a row spacing of 4 m × 4 m. The pollinating trees are Rainey and Sand Honey Bean. The applied reagent is a sleep-destroying agent for fruit trees prepared from 50% cyanamide and 0.48% boron in parts by mass, and it is prepared by adding 1500 times of Bijia during use. Two treatments were set up in the experiment: spraying 60 times of sleep-dispelling agent respectively, and spraying clear water as control. Both the main cultivar and the pollinated variety were treated, with 2 plants per treatment, repeated 3 times, and randomly arranged. On December 20, 2012, on the day when the greenhouse was opened and the temperature was raised, the whole tree was evenly sprayed once with a knapsack sprayer, and then ...

Abstract

The invention provides a dormancy breaking agent for fruit trees under protected cultivation and an application method. The dormancy breaking agent is prepared from 50% by mass of cyanamide and 0.48% by mass of boron, and when in use, Bijia with a mass being 1500 times of the amount of the agent is added. The application method comprises the following steps: smearing or spraying grapes under protected cultivation with the dormancy breaking agent with an amount being 20-25 times of the amount of the fruiting branches 1 week before the temperature increases; spraying nectarines under protected cultivation with the dormancy breaking agent with an amount being 60-80 times of the amount of the branches at the day when the temperature increases or 1-2 days before and after the temperature increases; spraying sweet cherries under protected cultivation with the dormancy breaking agent with an amount being 60 times of the amount of the branches at the day when the temperature increases or 1-2 days before and after the temperature increases; spraying plums under protected cultivation with the dormancy breaking agent with an amount being 60-100 times of the amount of the branches at the day when the temperature increases or 1-2 days before and after the temperature increases. The dormancy breaking agent of the invention is easy to prepare, low in price, and safe in use, enables fruit trees to sprout and bloom earlier and orderly, can concentrate the flowering period, increases the flower amount, enables the fruit maturity period of the treated fruit trees to be earlier and uniform, and can improve fruit quality.

Description

technical field [0001] The present invention relates to a sleeping aid for fruit trees and its use method, in particular to a sleeping aid for facility fruit trees and its use method. Background technique [0002] How to effectively break the dormancy of buds is one of the key technologies for early maturity to promote cultivation and normal growth in southern open field for deciduous fruit trees in protected cultivation in the north and open field cultivation in the south. Chemical substances such as nitrates, cyanamides, and plant growth regulators can replace part of the effect of low temperature, so that dormant buds end dormancy earlier, germinate and bloom earlier, and promote early growth. Preliminary research results show that potassium nitrate, lime nitrogen, cyanamide, gibberellic acid, etc. have certain effects on breaking dormancy and promoting maturity of fruit trees, but the difference is large, and the effect on promoting early maturity of fruit trees is not i...
