Orchard mulching

Orchard mulching

Orchard grass cover can create a good growth and development environment for the roots of fruit trees and even the entire tree body. It is an important technical measure to achieve high quality and high yield in dryland orchards.

Orchard grass cover has many advantages. First of all, it can change the groundwater, gas and thermal environment, promote the growth and development of trees, reduce the occurrence of diseases and diseases, improve the quality of fruits, and increase the economic benefits of fruit trees.

An orchard that is confined and not intercropped should be covered with grass, and young orchards should be partially covered with grass (tree or tree line). The crop stalks, leaves or orchard weeds are crushed (to facilitate coverage and rot) and evenly spread between the orchard rows and under the tree trays. The tree trays cover the grass to cover the root system (the outer edge of the canopy) and the thickness is 15~ 20 centimeters, press the soil a little bit on the grass to prevent wind blows and fire. Spring covered hay and summer pressed grass. Local grass-covered grass uses 1,000 to 1,500 kilograms of hay or 2000 to 3,000 kilograms of fresh grass, and 2500 to 4,000 kilograms of grass cover the entire park. Before mulching grass, combined with deep turning or deep watering, apply 0.2-0.5 kg of nitrogen fertilizer to meet the need of nitrogen fertilizer when microorganisms decompose organic matter, and apply fertilizer after cover. After the fall, the grass-covered garden should be shaved. In the fall, when applying the basal fertilizer, do not divert the grass to the ground. When topdressing fruit trees, they can split the grass, apply more points, and apply proper amounts of water after application. In winter and spring dry season, fire prevention should be taken care of. The thin layer of orchard can be a combination of trenching and grass cover. After 3 to 4 years of continuous ploughing, the basal fertilizer will be applied and will be replanted in the following year.
