Grape sleep breaker, what do you need to pay attention to when using sleep breaker to break the slee

The dormancy period of grapes refers to the normal physiological dormancy of grapes, grapes do not germinate and grow in winter, and it takes about 1000 hours of low temperature accumulation to break the dormancy, if the cooling requirements of grapes are not met, the grapes will not be able to pass the normal dormancy period, and then the next year will have uneven germination, and the flowering organs will be poorly developed, which will affect the yield and quality.

In the north, the grapes in the insulated canopy can't keep up with the cold.

In the south, where the average temperature is above 20°C, there are not enough cold hours.

How to solve the above two problems involves the use of grape sleep breakers!

What do you need to know about the use of grape sleep breakers?

The time it takes for vineyards in an area to go dormant can be extrapolated to the desired bud break time. Premature application requires a large number of ineffective concentrations of dormant busters, and late application can easily lead to injury.

2.Irrigation: Whether drip or flood irrigation, it should be done before dormant germination to increase space and soil moisture within the facility, and strong germination fertilizers should be used to promote winter bud germination.

3.Choose to apply on sunny days: the ambient temperature of 10-20 °C is more suitable, it is not easy to treat below 6 °C, and the air humidity in the facility should be kept above 80% and not less than 60% after being applied to hibernation. Apply the dormant period promptly after watering.

4.The dormant can be sprayed directly on the dormant branches (spraying should be comprehensive and even); Do not mix dormant agents with other agrochemicals; The 1-2 buds at the top of the branch should not be coated with buds, and only the bud eyes in the middle and lower parts of the branches should be coated with buds to prevent the apical dominance from causing the germination and growth of the top buds after coating, which will inhibit and affect the lower buds.

5.Wear protective clothing, gas masks, etc. when applying sleep breakers. Do not drink alcohol or smoke for 1 day before and after breaking sleep**, be careful not to inhale or drip on **, and wash your hands and face after the operation.

It should be noted that the germination time of early cultivation is generally selected about 20 to 50 days after the grapes are dormant; Before the sleep is induced, irrigation should be irrigated, drip irrigation or manchu champion, which can increase the facility space and soil moisture, and use it at the same time, and the tooth fertilizer is conducive to the germination of winter buds; Choose sunny weather for use, the ambient temperature is 10 to 20 degrees Celsius is more appropriate, below 6 degrees Celsius should not be treated, after the use of sleep breaker air humidity in the facility should be maintained at more than 80%, preferably not less than 60%.

It should be noted that it is necessary to choose a more appropriate time, and the use of sleep breakers must also be carried out in the spring, which may be better, of course, it can also be appropriately extended, according to the time of each region, and then you can make a different adjustment, and then you also need to pay attention to the amount of dosage must not be too much.

It is necessary to pay attention to the method of germination, the technique of germination, the damage to the grapes, and some diseases of the grapes, and continue to observe the state of the grapes.

Be sure to pay attention to the dosage used, pay attention to the time of use, choose the right temperature for use, be sure to pay attention to the time of hypnosis, and pay attention to the technique.

Be sure to water before germination, control the moisture of the soil, and keep the ambient temperature between 10 and 20.

<> "Concentration: per 500 grams of lime nitrogen (a grape sleep breaker), dissolve into 5 times the liquid with 40-50 kilograms of warm water in a plastic basin or bucket, stirring continuously during the period, and make it uniform into a paste after about 1-2 hours. How to apply:

Apply it with a sponge, cotton ball, etc., dip it in the liquid medicine, start to apply it upwards from the main stem of 40 centimeters of rice, and then put the grape branches down and stick to the ground with plastic film to balance the difference and moisturize.

<> grape monocyanamide sleep breaker is used at the end of grape dormancy, most of the monocyanamide content on the market is 50%, 250 ml of water is needed when used, and the slag celery can be sprayed directly or smeared on the bud eye, and the specific time of use also needs to be decided according to the annual average temperature.
