Brève description et caractéristiques techniques de la technologie

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.|
