Description

Technical Field

[0001] The invention relates to the field of wolfberry defoliants, in particular to a wolfberry defoliant and a preparation method thereof. Background Art

[0002] At present, during the growth process of wolfberry, due to the interference of leaves, pests attach to them, which is not conducive to drying. In addition, wolfberry is mainly picked by hand, which requires a lot of manpower, has low picking efficiency, and the picking process is easy to damage the wolfberry fruit, resulting in large losses.

[0003] In some areas, growers cut the branches directly from the wolfberry trees, which can directly kill the pests on the branches and cut off the "food" supply of the remaining pests. However, it is time-consuming and laborious to cut off the leaves of the wolfberry trees one by one; In some areas, growers directly apply alkaline water on wolfberry trees to remove leaves and dry them. It is difficult to remove leaves using only alkaline water, and the amount of alkaline water used needs to be increased. This method has the disadvantages of incomplete defoliation of wolfberries and uneven color of wolfberry fruits. After being picked, wolfberries are mixed with many broken leaves and need to be sorted multiple times. In addition, they are easily infected by pathogens while on the trees, resulting in many rotten fruits and a low yield. It will also cause the wolfberry trees to sprout later in the second year or even die branches.

[0004] Therefore, a wolfberry defoliant is needed, which can effectively dewax and dehydrate the leaves quickly and reduce the calcium ion content of the petiole, thereby achieving the purpose of defoliation. Summary of the invention

[0005] The purpose of the present invention is to provide a wolfberry defoliant and a preparation method thereof.

[0010] Preferably, the mixture is prepared from the following components by mass: 30 parts of potassium carbonate; 45 parts of sodium oxalate; 6 parts of ethephon; 12 parts of abscisic acid; and an appropriate amount of purified water.

[0011] A method for preparing a wolfberry defoliant comprises the following steps: mixing abscisic acid and sodium oxalate and stirring evenly to obtain a mixed solution A; Dissolving potassium carbonate powder in purified water to obtain potassium carbonate mother liquor; The mixed solution A was fully mixed with the potassium carbonate mother solution, ethephon was added, and the mixture was stirred evenly to obtain the wolfberry defoliant.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] Embodiment 1: The present embodiment provides a wolfberry defoliant, which is prepared by configuring the following components by weight: 50 parts of potassium carbonate; 40 parts of sodium oxalate; 8 parts of ethephon; 16 parts of abscisic acid; and an appropriate amount of purified water.

[0016] A method for preparing a wolfberry defoliant, the specific process is: mixing abscisic acid and sodium oxalate and stirring evenly to obtain a mixed solution A; Dissolving potassium carbonate powder in purified water to obtain potassium carbonate mother liquor; The A mixed solution is fully mixed with the potassium carbonate mother solution, ethephon is added, and the mixture is stirred evenly to obtain a wolfberry defoliant, which is used for defoliating wolfberry fruit trees.

[0017] Among them, potassium carbonate is prepared into white granular powder, with a relative density of 2.428 (19°C), a melting point of 891°C, and a pH value of about 11.6 for a 10% aqueous solution. The potassium carbonate aqueous solution is sprayed on the wolfberry leaves, which can quickly remove the wax layer on the surface of the wolfberry leaves due to its alkaline nature, thereby dewaxing and dehydrating the wolfberry leaves and accelerating the defoliation. Sodium oxalate, also known as sodium oxalate, has a molecular formula of C2O4Na2. It is a white crystalline powder with a relative density of 2.34 and a melting point of 250-270 degrees Celsius (decomposition). It is soluble in water but insoluble in ethanol. It has good biodegradability and low toxicity. It has excellent performance in removing calcium ions and detergency. Sodium oxalate combines with calcium ions in plants to destroy the composition of leaf cells, making the leaves fragile and promoting leaf shedding.

[0018] By mixing with ethephon, it becomes white needle-shaped crystals, which are easily soluble in water, methanol, acetone, ethylene glycol, propylene glycol, slightly soluble in toluene, and insoluble in petroleum ether. It is used as a growth stimulant for agricultural plants, enhancing the ability of cells to synthesize ribonucleic acid and promoting protein synthesis. For example, at the base of petioles, fruit stalks, and petals, due to the increase in protein synthesis, the decellulase in the abscission layer is resynthesized, which accelerates the formation of the abscission layer, leading to organ shedding; By mixing abscisic acid, whose chemical formula is C15H20O4, a growth-inhibiting plant hormone, it can induce leaf shedding.

[0019] The wolfberry defoliant prepared by the invention can rapidly dewax and dehydrate the leaves through the simultaneous action of potassium carbonate and calcium oxalate on the leaves of the plant, reduce the calcium ion content of the petiole, promote the increase of protein synthesis through the blending of abscisic acid and ethephon, and promote the resynthesis of cellulase in the abscission layer, so as to accelerate the formation of the abscission layer, cause the organs to fall off, and promote the leaves to fall off, thereby achieving the purpose of defoliation.
