Problems solved by technology

[0003] At present, for the prevention of bayberry fruit drop, the commonly used medicament is 2,4-D sodium salt. If the dosage exceeds 20ppm, it will cause phytotoxicity such as leaf curling, so there is a certain risk to production.
There are also articles reporting that the use of thiadizuron can effectively control bayberry fruit drop, but its residual risk has not been scientifically evaluated, and its use safety still has certain risks
In addition, there are also articles reporting that using net room cultivation can effectively prevent bayberry fruit drop, but because net room cultivation requires more manpower and material resources, and the cost is relatively high, it is not easy to popularize and apply in production
The prior art does not have a more efficient method for preventing fruit drop of red bayberry

preparation example Construction

[0015] The present invention has no special limitation on the preparation method of the bayberry anti-dropping agent, and it can be prepared by adopting conventional preparation methods of different dosage forms well known to those skilled in the art.

[0016] The present invention also provides a kind of method that prevents red bayberry fruit drop, comprises the following steps:

[0017] 15 days before red bayberry harvesting, spray the red bayberry fruit drop prevention agent described in the above technical scheme to the red bayberry fruit. 30mg / kg. The above concentration is the concentration of sodium p-chlorophenoxyacetate relative to water.

[0018] In the present invention, the bayberry anti-dropping agent is dissolved in water for spraying.

Embodiment 1

[0021] experiment method

[0022] The effect of anti-dropping agent sodium p-chlorophenoxyacetate on pre-harvest fruit drop of bayberry was carried out in Huangyan, Zhejiang Province. Every bayberry tree uses 3.5kg (L) of water, and it will be used separately with the bayberry anti-dropping agent of the present invention and the contrast agent, so that the interference of the agent is controlled at a minimum, and the accurate data of the application of the record agent is recorded.

[0023] Survey, Documentation and Measurement Methods

[0024] During the test period, the data of local rainfall (rainfall type) and temperature (daily average temperature, maximum and minimum temperature, expressed in °C) were recorded. Severe climatic factors that affect the test results during the entire test period, such as severe and long-term drought, heavy rain, etc., should be recorded.

[0025] Survey method, time, frequency

[0026] Every tree in every plot should be surveyed. If the...

Abstract

The invention relates to a fruit dropping prevention agent for waxberries and a method for preventing fruit dropping of the waxberries, and belongs to the technical field of fruit dropping prevention of fruit trees. The fruit dropping prevention agent for the waxberries provided by the invention contains sodium p-chlorophenoxy acetate. The fruit dropping prevention agent for the waxberries provided by the invention has an obvious fruit dropping prevention effect, the degradation of the sodium p-chlorophenoxy acetate is quick, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of fruit drop prevention for fruit trees, in particular to a bayberry fruit drop prevention agent and a method for preventing waxberry fruit drop. Background technique [0002] Red bayberry is a characteristic economic fruit in my country. Since the mature harvesting period of bayberry coincides with the rainy season, a large number of bayberry fruit will fall due to the influence of continuous rain in the usual year, plus pests such as red bayberry fruit fly, penicillium, green mold, The harm of the white rot fungus to the red bayberry fruit, as well as the damage of the strong wind to the red bayberry fruit and many other factors have caused the current situation of "half harvested and half rotten" year after year. [0003] At present, 2,4-D sodium salt is commonly used to prevent bayberry fruit drop. If the dosage exceeds 20ppm, it will cause phytotoxicity such as leaf curling, so there is a certain risk t...
