Cultivation means planting trees at the roots of plants. Cultivation is an extremely important step in plant growth. The general cultivation height is 15~20 cm. In areas with high groundwater level, heavy rain and strong wind, the planting height can be appropriately increased.
Soil cultivation can promote the development of plant roots and expand the absorption area of water and nutrition. It is more beneficial to adapt to the new growth environment after transplanting and improve the survival rate of plants. Through cultivation, the root system is deeper, the root system of plants is more developed, and the supporting ability is increased, which greatly improves the ability of plants to resist wind and lodging.
Ridges are formed between rows after soil cultivation, which can be irrigated along the ridges in dry days to ensure smooth water flow, uniform water quantity and save water; When it rains heavily, it can drain water smoothly, which can avoid and alleviate the flood disaster.
The cultivation of soil should be sufficient, so that the soil is in close contact with the plant base, and it should be carried out when the soil is dry and wet, so as to facilitate the occurrence and growth of plant roots.
