Intercropping method of caragana and Eucommia interplanting in arid desert area

A technology of caragana and desert, which is applied in the field of intercropping and intercropping of caragana and eucommia in arid desert areas, which can solve the problems of poor ecological effect of sand prevention and sand fixation, planting of a single caragana plant, and small coverage of caragana plants. Shorten the planting time, reduce the cost of afforestation, and overcome the effect of time-consuming and laborious

Problems solved by technology

However, in the afforestation process of Caragana afforestation, considering the competition between plants after forest formation under the extremely harsh conditions of the desert, only 300-500 clumps of Caragana per acre are suitable for planting. In the past 4 years, the coverage of Caragana plants was small, and the ecological effect of sand prevention and sand fixation was poor; and a single Caragana plant was planted, and the ability to resist disasters was weak, and there were potential disaster risks such as diseases and insect pests

Embodiment 1

[0032] Example 1 A method for interplanting Caragana interplanting with Eucommia in arid desert areas, comprising the following steps:

[0033] ⑴Excavation of caragana planting ditch:

[0034] 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 35 cm wide and 20 cm deep furrow in the east-west direction. The distance between the furrows is 3 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.

[0035] (2) Excavation of intercropping Eucommia planting ditch:

[0036] In the fall of the year before planting, a eucommia planting ditch with a width of 40 cm and a depth of 30 cm was opened in the area of ​​3m between the furrows of the caragana in the east-west direction, and 2000kg of mature farmyard manure was applied per mu before sowing in spring.

Embodiment 2

[0051] Example 2 A method for interplanting Caragana interplanting with Eucommia in arid desert areas, comprising the following steps:

[0052] ⑴Excavation of caragana planting ditch:

[0053] 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 40 cm wide and 22 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.

[0054] (2) Excavation of intercropping Eucommia planting ditch:

[0055] In the fall of the year before planting, a 45 cm wide and 35 cm deep eucommia planting ditch was opened in the area of ​​4 m between the furrows of Caragana japonica, and 2200 kg of mature farmyard manure was applied per mu before sowing in spring.

[0056] (3) seedling selection is the same as in Example 1.

Embodiment 3

[0066] Example 3 A method for interplanting Caragana interplanting with Eucommia in arid desert areas, comprising the following steps:

[0067] ⑴Excavation of caragana planting ditch:

[0068] 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.

[0069] (2) Excavation of intercropping Eucommia planting ditch:

[0070] In the fall of the year before the planting, a 50 cm wide and 40 cm deep eucommia planting ditch was opened in the area of ​​5 m between the furrows of the caragana, and 2500 kg of mature farmyard manure was applied per mu before sowing in spring.

[0071] (3) seedling selection is the same as in Example 1.

Abstract

The invention relates to a caragana microphylla and eucommia ulmoides intercropping method in an arid desert region. The method comprises the following steps that 1, caragana microphylla planting furrows are dug; 2, intercropping eucommia ulmoides planting furrows are dug; 3, seedlings are selected, wherein one-year-old caragana microphylla seedlings free of pest and disease damage and one-year-old eucommia ulmoides seedlings free of pest and disease damage are selected; 4, the seedlings are planted, wherein after soil is unfrozen in spring of the second year, a seedling planter is adopted for planting the caragana microphylla and eucommia ulmoides seedlings immediately after the caragana microphylla and eucommia ulmoides seedlings are dug out; 5 field management measures are taken. By means of intercropping of caragana microphylla and eucommia ulmoides, reciprocal symbiosis of caragana microphylla and eucommia ulmoides can be achieved under the arid desert condition, the problems that caragana microphylla planting has single benefit and the plant survival rate is low are solved, organic unification of desert treatment ecological, economic and social benefits is achieved, and therefore a technical support is provided for safe and efficient output of agriculture in the arid desert region.

Description

technical field [0001] The invention relates to an intercropping method in the field of forestry and desertification prevention and control, in particular to a method for intercropping caragana and eucommia intercropping in arid desert areas. 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] Eucommia is a deciduous tree with strong adaptability and wide distribution, and can be cultivated in most parts of our country. Eucommia grows best in full sun and well-drained, less demanding soils. [0004] Caragana microphylla is an important shrub species for soil and water conservation and sand-fixation afforestation in northern my country, which has important ecological value and economic significance. However, in the afforestation process of Caragana afforestation, considering the compe...
