Embodiment 1

[0049] 1. Selection of orchards: Choose mature orchards in arid agricultural areas, with plant-to-row spacing of 300cm×400cm, uniform growth, and relatively standardized management.

[0050] 2. Excavation of seepage pit 4: dig a long 200 cm, deep 50 cm, and wide 40 cm under the canopy of two fruit trees 1 each 50 cm apart.

[0051] 3. Preparation of micro-permeable plastic cloth 6: Fold a piece of plastic film with a length of 120*300 cm and slightly thicker (thickness above 0.02) in half horizontally, and then do not perforate the area within 15 cm from the fold line upwards as the anti-leakage area. Holes should be drilled for the leakage area beyond 15cm. The hole distance is about 10*10cm, and the hole diameter is 0.5cm.

[0052] 4. Building of seepage root micro-irrigation tunnel: Lay seepage bricks on the bottom and side walls of the seepage pit to form a tunnel 2. The underground passage is a mud brick or dry brick structure: lay a layer of bricks on the bottom of the ...

Embodiment 2

[0059] 1. Orchard selection: select the agricultural area in the arid area, with a plant-row spacing of 300cm×400cm, uniform growth, and mature orchards with relatively standardized management;

[0060] 2. Excavation of the seepage pit: Dig a circular soil pit with a diameter of 35-40 cm and a depth of 50 cm under the canopy of the fruit tree with a row spacing of 100 cm and a distance of 150 cm. The walls are required to be basically vertical.

[0061] 3. Production of plastic inner film for irrigation pit seepage: Find an inner film bag with a diameter greater than 20 cm and a height greater than 50 cm (chemical fertilizer inner film bag is also acceptable), and punch holes. The hole distance is required to be about 10*10cm, and the hole diameter is 0.5cm.

[0062] 4. The seepage pit is built with mud brick or dry brick structure: the bottom is covered with Panax notoginseng bricks, and the vertical bricks are round. Namely: Lay 4.5 bricks with Panax notoginseng sandwich at t...

Abstract

The invention relates to a dry farming area fruit tree rainwater collection infiltrating irrigation method, and belongs to the technical field of agricultural irrigation. The method specifically comprises the following steps of, digging a seepage pit, building a channel, laying micro-seepage cloth, building a cover body above the channel, reserving a water inlet and a water outlet in the cover body, arranging rain collecting slopes below two tree crowns, and laying a black film on the slopes from the tree crowns to the channel. According to the method, growth environment of fruit tree roots isimproved, and the air permeability of soil is enhanced; manual passive irrigation of fruit trees is changed into active water absorption, root system diseases of the fruit trees are effectively prevented and treated, meanwhile, the growth environment of the fruit trees is improved, and collected rainwater can be used in winter, spring and dry seasons in a cross-seasonal mode; and the problem thatcross-seasonal water supply in the whole growth period and the water demand critical period of the fruit trees in the dry farming area is prone to interruption and shortage is solved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a rain-collecting and infiltrating irrigation method for fruit trees in dry farming areas. Background technique [0002] In the prior art of agricultural irrigation, there are methods such as tree tray digging pits for corn stalks to store water for seepage irrigation, or burying plastic seepage barrels for seepage irrigation, and using mulch to cover tree trays to collect rain. Its disadvantages are: [0003] 1. The ineffective leakage of the tree tray digging is too large, the water storage time is short, and the water resources are wasted. [0004] 2. Waterlogging in the rainy season is easy to cause damage to the root system: suffocate the root system, induce soil-borne diseases, and even cause root rot and death. [0005] 3. Soaking in accumulated water for a long time can lead to the collapse of the seepage pit and cause unnecessary losses. [0006] 4. Th...
