Embodiment 1
[0016] Example 1 Example of the present invention
[0017] Implementation location: In the sloping green jujube orchard in the dry-hot valley area of Yuanmou County, Yunnan Province, Taiwan green jujube is planted in the orchard, and the row spacing of Taiwan green jujube is 3m×4m.
[0018] (1) Ditching and burying grass infiltration irrigation, see figure 1 , Ditch 1 along the 3 rows of fruit trees in the orchard, as long as the length of ditch 1 is consistent with the length of each row of fruit trees, ditch 1 is 50cm deep, ditch 1 is 35cm wide, ditch 1 is parallel to the row direction of fruit trees, and ditch 1 is with fruit trees The vertical distance of the stem base is 55cm, and the two ends of the irrigation ditch are blocked by plastic film 2 to prevent leakage; after the ditch 1 is opened, the straw bale is placed in the ditch 1, and the amount of the straw bale is more than the ditch surface 2- 3cm, in the process of orchard cultivation and management, use a moisture m...
Embodiment 2
[0031] Example 2 Control (traditional orchard flood irrigation technology)
[0032] The test site is the same as in Example 1. The other measures are the same as in Example 1, except that the irrigation method is to pump water from the reservoir to flood the orchard with bare soil and cover the soil without death.
[0033] The test data of Example 1 and Example 2 are shown in Table 1 and Table 2
