Talking about the Benefits of Lime Powder on Wheat Planting
Lime powder is very common in rural areas. Many farmers use lime powder. Lime powder can not only be used for building houses, but it also has many functions in agricultural production. The role of lime powder in agriculture is mainly manifested in three aspects. One is to prevent soil-borne bacteria, the other is to kill underground pests, and the third is to regulate soil acidity and alkalinity. These three aspects of lime powder can be used in wheat cultivation. Above, we will briefly understand the role of lime powder in wheat!
We can know that lime powder generally has three functions, so what is the specific effect of each effect? ​​And what are the benefits for wheat planting? The following will be introduced!
Prevention of soil-borne bacteria
Soil-borne bacteria show a typical heavy flood and cause serious yield losses for agricultural production. Therefore, how to avoid the spread of soil-borne bacteria and eliminate soil-borne bacteria in agricultural production is a major problem that needs to be solved. There are still many soil-borne diseases, such as root rot, sheath blight, and total eclipse. If left untreated, the bacteria will overwinter in the soil and increase the harm in the coming year.
The quicklime is strongly alkaline, and when it encounters the moisture in the soil, it will heat up the bacteria in the soil, and will also turn the soil into an alkaline environment, breaking the growth environment of the bacteria.
Kill underground pests
Underground pests cause serious damage to the roots of wheat. Many of the insect pests of the underground pests overwinter in the soil. After the damage, the crops, such as peanuts, will have more ascaris eggs. If no measures are taken, the damage will not be wheat but the coming year. The crops planted after the crop.
When lime powder is applied during wheat planting, it can solve underground pests and eggs and reduce the harm of underground pests.
Adjust soil acidity and alkalinity
In the north of China, the soil is relatively alkaline. However, the soil in many parts of the south of China shows acidity. For this type of soil, if the soil acidity and alkalinity cannot be adjusted in time, the plant will be more difficult to absorb mineral ions. At the same time, the root system is destroyed, resulting in poor plant growth. If it is wheat, it will affect the survival rate of wheat or the growth and development of plants.
Quicklime is alkaline, capable of neutralizing acidic soils, increasing soil pH, improving soil environment, and balancing soil.
Regarding the amount of quicklime, Xiaobian recommends 100-200 kg. Don't blindly pursue large quantities. After applying, you can take pH test paper to determine the acid-base environment of the soil. If the soil pH is too high (>8), don't Increase the amount of quicklime. Otherwise, it is also difficult to absorb and utilize some mineral elements. In other words, this amount must not be blind, and everything must be chosen according to the actual situation.
Green and functional cosmetics are more and more favored by people. As plant extracts are more and more widely used in cosmetics, more and more varieties are used. Compared with traditional cosmetics, cosmetics prepared with plant extracts as active ingredients have many advantages, such as overcoming the shortcoming of traditional cosmetics relying on chemical composite products, and making the safety of products higher; Natural components are more easily absorbed by the skin, making the effect of the product more significant; Functional more prominent, etc. Therefore, the application of plant extracts in cosmetics is the inevitable trend of market development. In addition, plant extracts have many obvious advantages, such as wide source and targeted mechanism of action. Especially with the progress of modern extraction technology and analysis technology, its effective ingredients and related mechanisms of action have been gradually discovered and confirmed by people, in the sunscreen, whitening, anti-aging, sterilization and other aspects of significant efficacy, can be widely used in various cosmetics. Therefore, the application prospect of plant extracts in cosmetics is very broad.
