Embodiment 1

[0022] First prepare raw materials: quicklime 10kg, sulfur 20kg, mountain spring water 100kg; then prepare auxiliary materials: washing powder 1kg, pebbles 5kg, the diameter of the pebbles is 0.5-1cm.

[0023] Add 100kg of mountain spring water into a large earthenware pot and heat it with fire. At the same time, add enough mountain spring water into a large earthenware pot and heat it to boil; put 20kg of sulfur powder in a plastic bucket and stir it with a small amount of 40℃ water to make a paste. shaped sulfur slurry.

[0024] When the water temperature in the large clay pot reaches 40 degrees, put 1 part of quicklime into the large clay pot to let it dissolve naturally. When the water temperature reaches 55°C, add 1kg of washing powder and stir evenly. When the water temperature reaches 100°C, slowly pour the adjusted sulfur slurry into the pot from the side of the pot, stir while pouring, and then pour in pebbles. Water level line; when the big clay pot boils again, sta...

Abstract

The invention relates to a method for producing lime sulfur. The method which relates to raw materials, auxiliary materials and technological steps is characterized in that the raw materials are quicklime, sulfur and spring water, the auxiliary materials are washing powder and cobblestone, and a large earthen pot is adopted to boil during boiling. The method has the following beneficial effects: the purity of the lime sulfur can be maintained through boiling by the earthen pot; the lime sulfur can be well adapted to sterilization, pest killing and acarid killing needs of fruit trees by using the spring water; quicklime and sulfur are firstly and respectively size-mixed into a slurry in the production to accelerate the reaction speed and make the reaction be fully carried out; a small amount of the washing powder is added during pouring the sulfur slurry makes sulfur be fully dissolved in water; and cobblestone is added to the pot to make cobblestone automatically stir in boiling water, so manpower can be reduced, full stirring can be realized, generations of bubble splashing and pot overflowing phenomena are reduced, and dangers of workers are reduced.

Description

technical field [0001] The invention relates to a production method of fruit tree pesticide products, in particular to a production method of lime sulfur mixture. Background technique [0002] Lime sulfur is a plant protection agent commonly used in agricultural production, and it has remarkable effects in controlling rust, powdery mildew, aphids, scale insects and other diseases and insect pests. [0003] Lime sulfur mixture is an inorganic sulfur preparation, which is strongly alkaline and corrosive, and its active ingredient is calcium polysulfide (CaS.Sx). Lime sulfur has a strong smell of rotten eggs, is unstable, is easily decomposed by oxygen and carbon dioxide in the air, and is not resistant to long-term storage. Lime sulfur mixture has insecticidal, acaricidal and bactericidal effects, and can prevent red spiders, scale insects, rust, powdery mildew, rot and canker on trees and flowers; in addition, the sulfur fine particles produced by decomposition after applica...
