There is a balance between the root system of the plant and the soil environment where the outside grows. When the moisture content in the soil is relatively high, the moisture in the plant enters the plant through the membrane of the root system, accompanied by a large amount of inorganic nutrients in the soil. element. However, when the water content in the soil is insufficient, the concentration in the root of the plant is lower than the external environment. This makes the activity mainly rooted in the soil environment, and the elements in the soil enter the plant. It is less, it will affect the growth of plants.
Soil moisture is divided into available water and non-usable water. The index reflecting the unusable water in the soil is the permanent wilting coefficient, which refers to the percentage of the soil moisture remaining in the soil when the plant is permanently wilted. The permanent wilting coefficient varies with the soil texture. The coarse sand is about 1%, the sandy soil is about 6%, and the clay is about 15%. On the soil of the same texture, the permanent wilting coefficient of different crops has changed very little.
Field capacity is the soil moisture content when all gravity water is removed from the soil and all capillary water and irreducible water are retained. Water is usually expressed as a percentage of the dry weight of the soil. When the soil moisture content is about 70% of the field water holding capacity, the most suitable cultivation, different texture of the soil, the field of water holding capacity is different. Sandy soil, 14% to 18%; medium loam soil, 22% to 27%; clay, 41% to 47%. The stronger the soil sand, the smaller the water holding capacity in the field, and the greater the soil viscosity, the greater the amount of water in the field.
In the process of plant growth, people often use high-tech products such as the soil moisture detector MST3000 and soil moisture detector SW3000 to coordinate the plant's required moisture content.

Forklift is an industrial transport vehicle, which refers to various wheeled transport vehicles for loading and unloading, stacking and short-distance transportation. Often used for transporting large items of storage, usually using a fuel engine or battery.Low center of gravity, small turning radius, more stable and reliable.Comfortable seat for long-time operation.
