Description
Technical Field
The invention belongs to the technical field of water retention and fertilizer conservation in tea gardens, and particularly relates to a tea tree under-root green manure and application thereof.
Background
The unique geographical and climatic advantages of the Qinba mountain area make the area become the key production area of high-quality tea.
Therefore, the tea industry is used as the dominant agricultural dominant industry in southern Shaanxi, the tea garden has large area and wide distribution range, but the tea quality is different due to large environmental difference. The soil for growing the tea trees is weakly acidic, and has good water permeability or water storage performance. On the hillside, the terrain is higher than that of the flat ground due to the terrain, and the tea trees can be easily illuminated by the sun in the process from rising to falling, but the tea trees are not convenient to irrigate, so that drought and fertilizer shortage are caused, and the yield and the quality of the tea trees are influenced.
The tea tree is different from the production of farmland crops such as corn, soybean and the like, and needs to grow some weeds around the roots, so that the weeds are needed to contain moisture and provide nutrients for the growth of the tea roots. If the weeds are removed completely, the water in the soil under the roots of the tea trees can be evaporated quickly, and the growth of the tea trees is not facilitated. Meanwhile, organic nutrients around the tea tree roots can be removed, so that the tea tree is lack of nutrition and the quality of tea is influenced. However, the excessive growth of weeds can seriously compete with tea trees for water and fertilizer, affect the growth of the tea trees and seriously affect the yield of tea leaves. If the weeds are completely compacted by an iron flat plate and cannot grow, the tea tree roots are rotted or soil moisture is seriously insufficient and oxygen demand is seriously insufficient due to the fact that the growing environment around the tea tree roots is changed sharply, so that the growth of the tea trees is inhibited, and the quality of the tea leaves is also seriously affected. The straw is used for pressing grass, although the effect is better than that of an iron flat plate, the straw can attract mice and cause loss to a tea garden. Therefore, the growth of grass cannot be well controlled when grass is planted in a tea garden, and the growth environment of tea trees cannot be well controlled.
