Dispersible solid preparation for preventing fruit drop and its preparation method and use

Abstract

The invention discloses a dispersible solid preparation for preventing fruits from falling, and a preparation method and application thereof. The dispersible solid preparation is prepared from the following mass percentages of components: 1%-95% of 1-methylcyclopropene microcapsules, 1%-10% of dispersant, 1%-10% of wetting agent, 0.1%-10% of stabilizer, and the balance of solid carrier, wherein the content of 1-methylcyclopropene in the dispersible solid preparation is 0.01%-4.75%. The dispersible solid preparation obtained by the invention has low moisture content, almost neutral pH value, excellent suspension property, wettability and heat storage stability, and the fineness up to 99.6%, so the preparation will not block nozzles. The sedimentation speed of the preparation is low, so thepreparation can continue to play drug roles for a certain period after application, satisfy the requirement of uniform distribution of medicinal liquid in an open orchard environment system and guarantee the action time, and has a very good effect of preventing fruit falling during harvest, and can prolong harvest time.

Description

technical field [0001] The invention relates to a preparation for preventing fruit drop, in particular to a dispersible solid preparation for preventing fruit drop and its preparation method and application. Background technique [0002] In order to reduce the loss of the fruit industry, relevant work can be carried out from two aspects of preventing fruit drop and post-preservation. At present, the method of preventing fruit drop mainly starts from two aspects: one is the cultural method, which suppresses the balance between plant growth and reproductive growth through fertilizer and water control, thinning flower buds, flowering girdling, etc.; the other is the use of plant growth regulation to To regulate the physiological state of fruit trees, it is generally used in the current production to spray gibberellin on the orchard before and after flowering and spray NAA before harvest. However, although spraying gibberellin can prevent flower and fruit drop, it will make the...

AI Technical Summary

Problems solved by technology

If directly process citrus with 1-methylcyclopropene, because the type of preparation directly used by 1-methylcyclopropene is a fumigant, the effect of the fumigant as spraying is very unsatisfactory; if it is made into a preparation, but the patent document There is no record of what type of preparation was made, let alone what advantages or technical problems it overcomes when making this type of preparation for spraying citrus

[0006] In short, on the one hand, for 1-methylcyclopropene fumigant, the 1-methylcyclopropene fumigant is put into water, the active ingredient 1-methylcyclopropene is released in a closed environment, and the target crops are treated in a closed environment. , and when it is used as spraying, it is impossible to seal the field orchard, which will greatly reduce the effect of 1-methylcyclopropene and greatly reduce the economic value; on the other hand, 1-methylcyclopropene fumigant has no special excipient The agent cannot be applied with oil or water, and excellent suspension performance and dispersion performance cannot be obtained, resulting in uneven distribution of the agent, clogging of the nozzle, etc.
