Problems solved by technology

However, in the afforestation process of Haloxylon afforestation, considering the competition between plants after forest formation under the extremely harsh conditions of the desert, only 300-400 Haloxylon trees are suitable for planting per mu, thus resulting in 1-400 Haloxylon trees before afforestation. In the past 4 years, the coverage of Haloxylon plants was small, and the ecological effect of sand prevention and sand fixation was poor; moreover, the ability to resist disasters was weak due to the single Haloxylon plant planting, and there were potential disaster risks such as diseases and insect pests.

Embodiment 1

[0037] Embodiment 1 A kind of intercropping method suitable for arid desert area Haloxylon and licorice, comprising the following steps:

[0038] ⑴Excavation of Haloxylon planting ditch:

[0039] At the end of autumn and early winter, the arid desert land is first leveled, and then a tractor with a plowshare is used to dig a 35 cm wide and 20 cm deep furrow in the east-west direction, and the distance between the furrows is 4 m. The wind and sand in the arid desert area are strong, and after a winter, the northwest wind will blow the fine sand and fill up the open ditch.

[0040] ⑵Land consolidation of intercropping licorice land:

[0041] In the fall of the year before planting, deep plow once in the area where the distance between furrows and furrows of Haloxylon is 4m. Before sowing in spring, apply farmyard manure and then deep plow once again, and apply 2000kg of mature farmyard manure per mu.

[0042] ⑶ Selection of seedlings:

Embodiment 2

[0060] Embodiment 2 A kind of intercropping method suitable for Haloxylon and Radix Glycyrrhizae in arid desert area, comprises the following steps:

[0061] ⑴Excavation of Haloxylon planting ditch:

[0062] At the end of autumn and early winter, the arid desert land is first leveled, and then a tractor with a plowshare is used to open a 40cm wide and 22cm deep furrow in the east-west direction. The distance between furrows is 4.5m. The wind and sand in the arid desert area are strong, and after a winter, the northwest wind will blow the fine sand and fill up the open ditch.

[0063] ⑵Land consolidation of intercropping licorice land:

[0064] In the fall of the year before planting, deep plow once in the area with a distance of 4.5m between the furrows of Haloxylon, apply farmyard manure before sowing in spring and then deep plow once again, and apply 2500kg of mature farmyard manure per mu.

[0065] (3) seedling selection is the same as in Example 1.

[0066] ⑷ planting: ...

Embodiment 3

[0080] Embodiment 3 A kind of intercropping method suitable for arid desert area Haloxylon and licorice, comprising the following steps:

[0081] ⑴Excavation of Haloxylon planting ditch:

[0082] At the end of autumn and early winter, the arid desert land is first leveled, and then a tractor with a plowshare is used to open a 45 cm wide and 25 cm deep furrow in the east-west direction, and the distance between the furrows is 5 m. The wind and sand in the arid desert area are strong, and after a winter, the northwest wind will blow the fine sand and fill up the open ditch.

[0083] ⑵Land consolidation of intercropping licorice land:

[0084] In the fall of the year before planting, deep plow once in the area with a distance of 5m between the furrows of Haloxylon, combine with farmyard manure before sowing in spring and then deep plow once again, and apply 3000kg of mature farmyard manure per mu.

[0085] (3) seedling selection is the same as in Example 1.

Abstract

The present invention relates to a kind of intercropping method suitable for Haloxylon and licorice in arid desert area, the method comprises the following steps: (1) Excavation of Haloxylon planting ditch; (2) Land arrangement of intercropping Glycyrrhiza; Haloxylon seedlings; (4) planting: after the soil thaws in the spring of the second year, use a seedling planter to pick up and plant the Haloxylon seedlings; (5) licorice seed treatment; (6) licorice seed direct seeding: on the cultivation surface between the furrows where Haloxylon is planted Sow the treated licorice seeds on the ground, flatten and suppress with a rake after sowing, and keep moisture; (7) Field management measures. The invention interplants Haloxylon and Glycyrrhiza interplanting, which can realize mutualistic symbiosis of Haloxylon and Glycyrrhiza under arid desert conditions, not only solves the problems of only planting Haloxylon and low plant survival rate, but also achieves ecological, economical and ecological benefits of desert control. The organic unity of social benefits provides technical support for safe and efficient agricultural output in arid desert areas.

Description

technical field [0001] The invention relates to an intercropping method in the fields of forestry and desertification prevention and control, in particular to an intercropping method suitable for arid desert regions such as Haloxylon and licorice. Background technique [0002] The situation of desertification in China is very severe, and it is one of the most serious desertification countries in the world. How to control desertification has become an urgent problem to be solved. [0003] Licorice is a leguminous plant, distributed in the continental climate zone. It absorbs groundwater with its deep roots to adapt to the arid environment. . It grows well in hot desert and semi-desert areas in summer; wild species are born on the calcareous soil of grasslands, and are plants with strong salt resistance. [0004] Haloxylon is a kind of drought-resistant, wind-erosion-resistant, saline-alkali-resistant plant, which has a relatively common distribution in the desert and semi-d...
