Background technique

Lime is an air-hardening inorganic gelling material mainly composed of calcium oxide. Lime is made of products with high calcium carbonate content such as limestone, dolomite, chalk, and shells, which are calcined at 900-1100°C. The use of lime in agricultural production mainly has the following five aspects:

1. Lime fertilizer: Applying lime to acidic soil can neutralize the acidity of the soil, eliminate the poison of aluminum ions to crops, improve the activity conditions of beneficial microorganisms in the soil, and promote the effectiveness of soil nutrients, especially phosphorus; improve the physical properties of the soil plow layer. traits, improve soil absorption and soil fertility.

2. Using quicklime and other raw materials to prepare lime sulfur mixture and Bordeaux mixture can prevent and control various diseases.

3. Brush fruit trees and other trees with lime to prevent overwintering pests and diseases on the trunks and protect them from pests.

4. Use lime milk to protect and prevent diseases. For fruit tree plaster disease, you can use a knife to scrape off the mycelium film and then spray 20% lime milk. In winter, pruning branches with wounds larger than 2 cm can be smeared with 30% lime water to protect the wound.

5. It is used for environmental disinfection. It is often used for disinfection of livestock and poultry breeding sites and environments, as well as clear ponds and water bodies for aquaculture.

Lime is divided into quicklime and slaked lime, and slaked lime [Ca(OH)2] has the property of alkali. It is weaker in alkalinity or corrosion than soda lime, and it can be said to be a medium-strong alkali. These properties determine that slaked lime [Ca(OH)2] has a wide range of applications.

When lime is applied in farmland, slaked lime is usually used. In the past, it was spread manually. However, manual spreading is labor-intensive and easy to cause harm to the human body. With the advancement of technology, some mechanized lime spraying has also appeared. However, it is mainly used for engineering defense lines, and there are only some simple devices for agriculture, which cannot be used for farmland operations, and the mechanical lime spreading currently used is directly through a screen with holes or grooves. If the lime is scattered, because the slaked lime is very viscous, if these holes or grooves are too small, they will easily be blocked. , so how to improve the lime spreading of farmland operations is still a difficult problem to be solved.

No patent literature report directly related to the technology of the present invention has been found through searching, but there are some similar patent literature, and the patents that are mainly related to the present invention are as follows:
