Embodiment 1

[0048] Step 1, under the canopy, open a fertilization ditch along the row of the tree, with a depth of 20 cm and a width of 30 cm;

[0049] Step 2, in the fruit tree stage, apply 2000kg farm manure, 20kg nitrogen fertilizer, 15kg phosphate fertilizer, 20kg potash fertilizer per mu to the fertilization ditch opened in step 1;

[0050] Step 3, irrigate biogas slurry and biogas residue in the ditch that has been fertilized in step 2, and the irrigation amount in the ditch corresponding to each fruit tree (the ditch that has been fertilized) is 25kg;

[0051] Step 4: Backfill the fertilization ditch after filling biogas slurry and biogas residue in step 3 to a point 5 cm below the ground, and then cover the backfilled fertilization ditch with black plastic film. The plastic film covers the fertilization ditch to form a low center and slightly higher sides. Concave type, when the plastic film is covered, it needs to be stretched, straightened, without wrinkles and close to the fert...

Embodiment 2

[0056] Step 1, under the crown of the tree, open a fertilization ditch along the row of the tree, with a depth of 25 cm and a width of 40 cm;

[0057] Step 2, in the fruit tree stage, apply 2500kg farm manure, 25kg nitrogen fertilizer, 18kg phosphate fertilizer, 22kg potash fertilizer per mu to the fertilization ditch opened in step 1;

[0058] Step 3, irrigate biogas slurry and biogas residue in the ditch that has been fertilized in step 2, and the irrigation amount in the ditch corresponding to each fruit tree (the ditch that has been fertilized) is 50kg;

[0059] Step 4: Backfill the fertilization ditch after filling biogas slurry and biogas residue in step 3 to 8cm below the ground, and then cover the backfilled fertilization ditch with black plastic film, and the plastic film covers the fertilization ditch to form a low center and slightly high sides The concave shape of the film must be stretched, straightened, wrinkled and close to the fertilization ditch when covering ...

Embodiment 3

[0064] Step 1, under the canopy, open a fertilization ditch along the row of the tree, with a depth of 30 cm and a width of 50 cm;

[0065] Step 2, in the fruit tree stage, apply 3000kg farm manure, 30kg nitrogen fertilizer, 20kg phosphate fertilizer, 25kg potash fertilizer per mu to the fertilization ditch opened in step 1;

[0066] Step 3, irrigate the ditch that has been fertilized in step 2, and the amount of water in the ditch corresponding to each fruit tree is 100kg;

[0067] Step 4: Backfill the fertilization ditch after watering in step 3 to 10cm below the ground, and then cover the backfilled fertilization ditch with black plastic film. The plastic film covers the fertilization ditch to form a concave shape with a low middle and slightly higher sides. It needs to be tightened, straightened, wrinkle-free and close to the fertilization ditch. The depth of the mulch film on both sides of the fertilization ditch is buried in the soil at a depth of 15cm, and it should be ...

Abstract

The invention discloses a method for improving the utilization rate of fertilizer and water in an orchard on dry land, which comprises the following steps: opening a fertilization ditch; applying fertilizer to the opened ditch; irrigating the fertilized ditch; and covering the irrigated ditch with plastic film ; Block the soil in sections on the covered plastic film; punch holes in the plastic film that blocks the soil; plant green manure between the rows of trees. In the present invention, the "fertilizer, water, and film integration" technology is adopted for the orchard to combine the film covering with the fertilization ditch, and mainly use the rainwater collected in the early stage and the later stage to pour into the fertilization ditch to realize the integration of water and fertilizer, and improve the water and fertilizer. The interaction effect realizes the local enrichment of fertilizer and water in the rhizosphere soil of fruit trees, which can improve the micro-environment of the rhizosphere of fruit trees, effectively supply nutrients and water to fruit trees, strengthen the trees, and significantly improve the yield and quality of apples.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and relates to a method for improving the utilization rate of fertilizer and water in dry land orchards. Background technique [0002] The main surface cultivation techniques of orchards are as follows: 1. Clear tillage irrigation, which is a traditional water cultivation mode suitable for orchards with irrigation conditions. However, for orchards with irrigation conditions, no mulching treatment is performed after irrigation, and the surface soil moisture evaporates. If it is too fast, the water use efficiency will be greatly reduced. 2. Orchard grass growth system, which is a soil moisture management method for the whole orchard or between rows, so that the soil surface is not exposed, and is mowed several times a year, or not mowed all the year round. Long-term grass can maintain soil Improve the basic fertility of the soil, improve the comprehensive fertility of the soil, impr...
