The invention provides a tree wound healing protective agent, which consists of the following components in percentage by weight: 0.1-3 percent of sterilizing agent, 35-48 percent of protective agent, 0.1-8 percent of nutrient, 0.1-3 percent of pigment, 30-50 percent of adhesive, 0.1-8 percent of regulator, 1-5 percent of auxiliary agent and 10-26 percent of water. The preparation method comprises the following steps of: adding water into a reaction kettle; adding the nutrient and the regulator with stirring; heating to maintain solution at 45-65 DEG C; stirring for 30-60 minutes; stopping heating and keeping stirring; naturally cooling mixture in the kettle and adding the adhesive and the auxiliary agent; stirring for 70-90 minutes; stopping heating; adding the sterilizing agent and the pigment with stirring; stirring for 30-50 minutes and then adding the protective agent; and then stirring for 90-240 minutes and stopping. The protective agent has a special effective effect on rotten scars, canker scars, gummosis scars, and cut and saw cut of fruit trees.

The invention provides an anti-mosquito fish tank, which comprises a fish tank and a tank seat, wherein the fish tank is provided with an anti-mosquito oxygenation device, the anti-mosquito oxygenation device comprises a water curtain pump, a water curtain spray head, a small swinging boat and a controller, an output opening of the water curtain pump is connected with the water curtain spray head through a connecting pipe, a water inlet opening of the water curtain pump is positioned in water of the fish tank, the water curtain spray head is positioned besides the fish tank, and the small swinging boat is positioned on the water surface of the fish tank and is provided with a traction rope to be fixedly connected with the fish tank. The water surface of the fish tank is separated from the outside by the water curtain, the egg laying by mosquitoes on the water surface of the fish tank is prevented, meanwhile, the impact force generated when the water curtain falls down is used for impacting the small swinging boat, the water surface of the fish tank swings through the swinging of the small swinging boat, the egg laying by the mosquitoes on the water surface of the fish tank is prevented, and the mosquito breeding in the fish tank is prevented.

The invention belongs to a tree protection product in the field of agriculture and forestry planting, and specifically relates to a long-acting multifunctional tree protection agent for preventing animal bites, preventing diseases and insect pests, and preventing freezing and a processing method thereof. The purpose of the invention is to prevent cattle, sheep and other herbivores from gnawing, prevent pests from laying eggs and germs from breeding, avoid sunburn and freezing damage of trees, improve tree survival rate, promote healthy growth and development of trees, and speed up afforestation and greening. The long-acting multifunctional tree protection agent is composed of the following raw materials: lime powder, sulfur powder, latex, plant extract, fatty acid emulsion, and water. The processing method is as follows: 1) adding lime powder, sulfur powder and latex to prepare a base liquid; 2) taking plant extracts and pouring them into the base liquid and stirring them evenly; 3) slowly pouring the fatty acid emulsion into the base liquids and stirring them evenly. The invention has the following beneficial effects: rich source of raw materials, simple manufacturing process, convenient use, easy operation, no pollution, not restricted by region and environment, and has a prospect of popularization.

The invention discloses a plant wound healing protective agent, which consists of the following components in percentage by weight: 0.1 to 8 percent of bactericide, 0.1 to 11 percent of nutrient, 40 to 85 percent of protective agent, 1 to 6 percent of pigment, 2 to 20 percent of tackifier, and 8 to 20 percent of water. The invention also discloses a preparation method of the protective agent, which comprises the following steps of: firstly, adding water and stirring; secondly, adding the nutrient and tackifier with stirring, heating the solution to 30 to 60 DEG C, and stirring for 10 to 50 minutes; thirdly, adding the pigment with stirring, and after continuously stirring for 10 to 60 minutes, stopping heating; and finally, adding the bactericide, after stirring for 10 to 40 minutes, adding the protective agent, and after stirring for 60 to 240 minutes, stopping stirring. The plant wound healing protective agent has good effect on the infection caused by Cytospora, canker, gummosis and other fungus and bacteria pathogenic bacteria, and has special effect on the protection of rot scars of fruit trees, canker scars, gummosis scars and wounds and saw bites.
