Unearthed fruit and vegetables are popular and have many advantages, without fear of heavy problems, and produce high-quality fruit. Some farmers say that there are many different places in which the melon fruit and vegetables are grown, and that the melon fruit is then planted without covering the membranes
Vegetables of melons are grown in large sheds of soil, some of which, after planting, cover the membranes, some of which first cover the membranes before perforating them. Soil cultivation usually occurs in winter or early spring, with increases in the temperature of the ground, protection against weeds, reduction of soil moisture, reduction of water loss, etc. When the membranes are covered, the membranes are levelled onto the planting pads, attached to the soil, and the earth is pressed around them. The membrane can also be covered when the matrix is grown or when the guacamole is grown, but the way the membranes are grown and the soil is grown varies。
Vegetables need to grow at appropriate temperatures, and the temperature within the planting tanks is the growth temperature of the root system. The non-earth-planted guacamole is also wetted and protected against weeds, but mainly in order to maintain the temperature in the planting tanks, which do not vary significantly in the event of high temperatures or cold weather, preventing damage to root systems. There is also the role of root systems, which need to grow in a light-shield environment, followed by a dark environment that prevents drying of the outside roots. As a result, fruit and vegetables are cultivated without soil, and the membranes have different effects and soils。
Earth-free membranes, commonly used silver black, double-coloured membranes, this silver face up, and black down. The unearthed guacamole is not just covered by the surface; it covers the entire planting cell and the floor on both sides of the plant, with both ends fixed. After the membranes, the membranes and the planting tanks were not attached, the planting tanks, the floors between the growing rows and the membranes formed a triangular space where the air flowed and the temperature stabilized. During the cold winter period, the temperature in the planting bag can be increased and the summer can also serve as a shade to reduce the temperature in the tank。
For example, the temperature of roots is difficult to manage with hydroponic cultivation of guacamole, and nutrients in the planting tanks are susceptible to external influences and temperature changes are significant. After covering the film, the temperature in the planting tanks is maintained, with a warmer winter, and the temperature in the summer tanks is not particularly high. After unearthed-planted coverings, root temperature management is very helpful, root systems are well developed and absorbent water is more fat, and there is a difference between the strength of the unduplicate film。
There is also an advantage in covering the membrane when the melon fruit and vegetables are planted without soil, and the membrane costs are low, and the temperature in the planting tanks can be maintained and the root temperature can be managed。
