Specifications

Section 1. Context of the best practice: frame conditions (natural and human environment)

Short description of the best practice

Use plastic film mulching and under-film drip irrigation to the plantation of dates, apricot and other cash crop species to overcome sandlot water leakage and for the purpose of water conservation, increase forestation survival rate, prevention of wind harm, sand fixation in areas near Taklimakan Desert. Application of Mulched Drip Irrigation can increase forest survival rate.|

Outline specific land degradation problems addressed by the best practice

The drifting sand and wind erosion was addressed.

Specify the objectives of the best practice

1. Increase forest survival rate.
2. Save water resource.
3. Improve labor productivity and increase income.

Section 3. Activities

Brief description of main activities, by objective

1. Constructed water conservancy facilities.
2. The inbedded tubing was designed.
3. Gravity drip irrigation was adopted.
1. Site preparation.
2. Install the drip irrigation equipment and establish the mulch.
3. Grasses were planted under the forest and intercropping is maximized to add vegetation coverage for wind prevention, desert fixation, control of soil erosion, soil fertility improvement and fodder production.
No answer provided.
1. Strengthen orchard tree pruning, water and fertilizer management. Maintain irrigation system regularly.
2. Make full use of outstanding light and thermal resources at the project site to select good suitable horticulture species.
3. Ancillary technical measures were adopted including date dwarfing dense plantation technique, pollution-free cultivation technology, etc. to increase production.|

Short description and technical specifications of the technology

In the outskirt of ecological demonstrative district, shelterbelt forest is lined up against the prevailing wind direction (westward and northward) at the width of 116m and in parallel with the prevailing wind at the width of 50m. Inside the shelterbelts, “narrow belt and small grid’ strip croplands are configured with standard strip land shelter forest established. The orchard grid may be configured per 250m×125m pattern and the main shelterbelt is arranged in 15-20 m width in 7-10 rows perpendicular to the prevailing wind. The belts in parallel to the prevailing wind are configured in 10-15m width in 5-8 rows. Drip irrigation for orchard trees is set in 0.5m drip hole spacing, with the 16mm inner diameter drip tubes, and a nozzle rated flow at 2.8L/h (10m pumping head as rated pressure), and working head ranges from 8 to 20m. The rated irrigation for young fruit trees is 4.73 cubic meters/ mu and irrigation cycle is 3 days. During full fruiting season the rate is adjusted to 18.31 cubic meters/ mu and the cycle is 3.5 days.|
