Method for fertilizing fruit tree in dry sloping field

Abstract

The invention discloses a method for fertilizing a fruit tree in a dry sloping field. The method comprises the steps of digging a pit at a position 1.5-2.0m away from a tree trunk root under a tree crown of a fruit tree in a dry sloping field; vertically inserting a plastic tube into the pit, and ensuring that the tube orifice of the plastic tube is higher than the earth surface; irrigating a proper amount of water and applying a proper amount of compound fertilizer into the plastic tube according to the requirement of the fruit tree on water and fertilizer; and after irrigation and fertilization are completed, sealing the tube orifice by using a plastic bag. As the water and the fertilizer directly reach 1.0-1.5m below the earth surface, plant roots have fertilizer taxis and hydrotaxis, and the fruit tree is facilitated to be deeply rooted underground (with deep roots and luxuriant leaves), so that the fruit tree is lodging-resistant and water loss and soil erosion can be avoided; as the water and the fertilizer directly and deeply reach the underground, weeds on the earth surface are unlikely to compete with the fruit tree for the water and the fertilizer; in addition, after fertilization and irrigation, the tube orifice is immediately sealed, the water and the fertilizer are difficult to evaporate, and the water and fertilizer utilization rate is improved; the fertilization and irrigation modes in the method are simple and easy to operate, the labor cost can be saved, the fertilizer can be applied and water can be irrigated in time according to the law of the requirement of the fruit tree on the water and the fertilizer in different periods, and high yield and high quality of fruit can be guaranteed.

Description

technical field [0001] The invention relates to the irrigation field of agriculture and forestry, in particular to a method for fertilizing fruit trees on dry slopes. Background technique [0002] The dry slope land has thin soil layer, poor soil quality, complex geological structure, and low water and fertilizer retention capacity, which make it difficult for fruit trees to grow in good fertilizer and water conditions, making it difficult to achieve the goal of "high yield and high quality". Existing methods such as sprinkler irrigation, drip irrigation, and flood irrigation are basically impossible to implement on dry slopes due to the large water demand. At present, the method of fertilizing water in many holes is used, because the fertilizer and water are replenished from the surface, resulting in fast evaporation of fertilizer and water, and serious leakage, which is uncontrollable. How to convert farmland to forests and prevent water, fertilizer, and soil loss on dry ...

Existing methods such as sprinkler irrigation, drip irrigation, and flood irrigation are basically impossible to implement on dry slopes due to the large water demand

At present, the method of fertilizing water in holes is widely used. Because the fertilizer and water are replenished from the surface, the fertilizer and water evaporate quickly, and the leakage is serious, which is uncontrollable.
