Embodiment 1

[0022] A method of fertilizing dryland orchards based on ditch storage of fertilizer and water management, which integrates technologies such as ditch storage of fertilizer and water for film mulching, concentrated application of organic fertilizers, and quantitative application of chemical fertilizers, including the following steps:

[0023] Step 1. Ridging and mulching time should be selected from the time after the late-maturing varieties are harvested to before the soil is frozen, usually in mid-October to early November, combined with autumn base fertilizer application. The thickness of the mulch generally requires a black film of 0.025mm or more, and the width is 80cm~100cm. The choice of horticultural ground cloth can be covered continuously for three years, and the choice of plastic film needs to be relaid every year.

[0024] For ridges, the ridge surface takes the trunk as the center line and the tree crown as the boundary. The middle is high and the sides are low, f...

Embodiment 2

[0034] The total amount of fertilization is 0.6 kg of pure nitrogen per 100 kg of fresh fruit produced, P 2 o 5 0.3 kg, K 2 O is 1.0 kg.

[0035] The ratio of basal fertilizer to the total amount of fertilization is N 55%, P 2 o 5 65%, K 2 O 25%.

[0036] The first topdressing period was in early June, and the ratio of chemical fertilizer application to the total amount of fertilization was N 25%, P 2 o 5 35%, K 2 O25%. The second topdressing period is in early August, and the ratio of chemical fertilizer application to the total amount of fertilization is N 5%, P 2 o 5 15%, K 2 O 45%.

Embodiment 3

[0038] The total amount of fertilization is 1.0 kg of pure nitrogen per 100 kg of fresh fruit produced, P 2 o 50.6 kg, K 2 O is 0.6 kg.

[0039] The ratio of basal fertilizer to the total amount of fertilization is N 65%, P 2 o 5 55%, K 2 O 35%.

[0040] The first topdressing period was in late June, and the ratio of chemical fertilizer application to the total amount of fertilization was N 35%, P 2 o 5 25%, K 2 O35%. The second topdressing period is in mid-August, and the ratio of chemical fertilizer application to the total amount of fertilization is N 15%, P 2 o 5 5%, K 2 O 35%.

Abstract

The invention discloses a fertilizing method for managing a dry land orchard based on ditch storage of fertilizer water. The fertilizing method comprises the steps of ridging, film mulching and fertilizing for the orchard, wherein ditching is carried out on two sides of a fruit tree trunk after ridging and film mulching in the orchard for the ditch storage of fertilizer water; a fertilizing process comprises the steps of applying base fertilizers and applying additional fertilizers, wherein the base fertilizers comprise organic fertilizers and chemical fertilizers, the additional fertilizers are chemical fertilizers, the organic fertilizers are applied in a centralized manner, and the chemical fertilizers are applied in a quantitative manner; and the method is strong in operability, and isbeneficial to improving the organic matter content of the soil and improving the physicochemical properties of the soil.

Description

technical field [0001] The invention belongs to the technical field of fertilization methods for orchards, and in particular relates to a fertilization method for managing dryland orchards based on ditch storage of fertilizer and water. Background technique [0002] Water is the central molecule of life and plays an important role in many aspects of many life processes of plants. Due to the imbalance of physiological and environmental conditions in the natural state, plants will suffer from drought stress, resulting in crop yield reduction, which in turn leads to interruption of agriculture and food supply in different parts of the world, threatening human survival and development. The annual rainfall on the Loess Plateau is about 400mm, with uneven seasonal distribution and large inter-annual changes. "Nine droughts in ten years, and spring droughts every year". The fruit expansion period from May to July every year continues high temperature and drought, resulting in poor ...
