What does it mean to keep soil moisture?

The meaning of moisturizing is as follows:

Soil moisture conservation refers to maintaining the moisture content in the soil through a series of measures and technical means to avoid excessive evaporation and loss of soil moisture, thus maintaining soil moisture and providing a good growth environment for crops. The purpose of soil moisture conservation is to improve soil water use efficiency, promote plant growth and increase crop yield.

Soil moisture conservation technology mainly includes the following aspects:

1. Plant reasonable plants. Selecting plant varieties with strong adaptability and drought tolerance, such as drought-resistant crops or drought-resistant plants, can reduce the evaporation and loss of soil water.

2. Soil improvement measures. By increasing organic matter content, improving soil structure, improving soil water-holding capacity and water-holding capacity, reducing water evaporation and loss.

3. Cover and keep moisture. Use mulch (such as straw and plastic film). Covering the soil surface can reduce soil water evaporation and inhibit the growth of weeds, thus improving soil water retention capacity.

4. Rational fertilization. Apply fertilizer scientifically and reasonably to avoid soil water loss caused by excessive fertilization, provide sufficient nutrient supply and promote crop growth.

5. Reasonable irrigation. Adopt scientific and reasonable irrigation methods and irrigation amount to avoid excessive supply and waste of water and reduce soil water loss.

The benefits of soil and water conservation mainly include the following aspects:

1. Improve the yield and quality of crops. Soil moisture conservation can provide a good growth environment for crops, reduce water evaporation and loss, improve soil water use efficiency, thus promoting crop growth and increasing yield.

2. Reduce soil erosion. Soil moisture conservation can reduce the speed and intensity of rain scouring the soil, prevent the soil from being washed away and protect the soil quality.

3. Save water resources. Through reasonable soil and water conservation measures, irrigation water consumption can be reduced and water resources utilization efficiency can be improved.

4. Increase soil fertility. Soil moisture conservation can promote the accumulation of organic matter in soil, improve soil fertility and improve soil quality.

In a word, moisture conservation is an important agricultural production measure. Scientific and rational management of soil moisture can increase crop yield, reduce soil erosion, save water resources and improve soil fertility, which is of great significance to ensuring food security and sustainable agricultural development.
