Drainage method for orchard by raising high ridges

Abstract

The invention discloses a drainage method for an orchard by raising high ridges, which relates to the technical field of fruit farming. The technical scheme of the invention comprises the following steps: raising high ridges in the orchard, fix planting fruit trees on the ridges, digging drainage ditches between the lines of fruit trees by a certain gradient (slope) slightly according to the terrain and water flow direction, and laying trickle irrigation in the lines of fruit trees. The method of the invention adopts raising of high ridges and setting up of drainage ditches between the lines of fruit trees and the other measures to realize the effective drainage in rainy season for the orchard, and avoids the unbalance of water supply for fruit trees caused by permeation of untimely rainfall into orchard soil in rainy season; and trickle irrigation devices are laid in the lines of fruit trees to perform irrigation at the critical period of water requirements of fruit trees, so as to realize manual control of water supply for the orchard. According to above measures, the manual control of water supply for the orchard can be realized, the content of soluble solids of fruits is increased remarkably and the fruit quality is improved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation. Background technique [0002] The water supply of fruit trees is one of the key measures in orchard management. Timely and appropriate water supply can ensure high-yield and high-quality fruit. However, the current open-field cultivation of fruit trees has not fully realized the artificial control of water management of fruit trees: the existing irrigation technology can water according to the soil moisture when the orchard needs water; and the orchard drainage measures are only for preventing the rainy season Excessive precipitation leads to waterlogging, dig drainage ditches, and drain water when waterlogging or flooding occurs; author Qin Lizhe published an article titled how to manage waterlogged apple trees ("Hebei Agricultural Science and Technology" 2007, No. 11, P29 ) introduced that after the orchard is flooded, production and self-rescue should be carried out in time. The...

Untimely precipitation infiltrates into the orchard soil, resulting in an imbalance in the water sup
