Embodiment 1

[0051] Present embodiment relates to the method for interplanting Jerusalem artichoke under forest, comprises the following steps:

[0052] (1) Seed selection and seed potato treatment

[0053] a, seed selection: select forage type Jerusalem artichoke (No. 21 Langyu) as interplanting species, select tubers with a single block size of 3 cm as Jerusalem artichoke seed potatoes, wherein half of them retain 1 bud eye and half of them retain 2 bud eyes;

[0054] b. Seed potato treatment: Soak the seed potato pieces with 1% potassium permanganate for 2 minutes, then remove and dress with plant ash;

[0055] (2) Pre-broadcast preparation

[0056] The present embodiment selects the fast-growing forest land of 3-5 years of poplar species in Pingshan County, Shijiazhuang, Hebei Province as the plantation forest land, and its row spacing is 2m*6m.

[0057] a. Soil preparation: deeply plow the soil of the planted woodland to a depth of 25 cm;

[0058] b. Fertilization: 4000kg of decomp...

Embodiment 2

[0071] (1) Seed selection and seed potato treatment

[0072] a, seed selection: select processing type Jerusalem artichoke (No. 2) as the interplanting variety, and select tubers with a single block size of 4 cm as Jerusalem artichoke seed potatoes, wherein half of them retains 1 bud eye and half retains 2 bud eyes;

[0073] b. Seed potato treatment: Soak the seed potato pieces with 1% potassium permanganate for 3 minutes, then remove them and dress them with plant ash;

[0074] (2) Pre-broadcast preparation

[0075] In this embodiment, the fast-growing poplar species of Populus tomentosa in Zuogezhuang, Wuqing County, Tianjin City is selected as the plantation forest land, and the row spacing between plants is 2m*6m.

[0076] a. Soil preparation: deeply plow the soil of the planted woodland to a depth of 27 cm;

[0077] b. Fertilization: 3500kg of decomposed farmyard manure, 8kg of pure nitrogen, 15kg of pure phosphorus, and 5kg of pure potassium are applied to the forest l...

Embodiment 3

[0090] (1) Seed selection and seed potato treatment

[0091] a, seed selection: select the fresh-eating type Jerusalem artichoke (No. 1) as the interplanting variety, and select the tuber with a single tuber size of 4 cm as the Jerusalem artichoke seed potato, wherein half of it retains 1 bud eye, and half of it retains 2 bud eyes;

[0092] b. Seed potato treatment: Soak the seed potato pieces with 1% potassium permanganate for 3 minutes, then remove them and dress them with plant ash;

[0093] (2) Pre-broadcast preparation

[0094] In this embodiment, the poplar economic forest land in Cuizhuang Town, Jiuzhou Town, Guangyang District, Hebei Province is selected as the plantation forest land, and the row spacing is 3m*5m.

[0095] a. Soil preparation: deeply plow the soil of the planted woodland to a depth of 27 cm;

[0096] b. Fertilization: 3200kg of decomposed farmyard manure, 6kg of pure nitrogen, 12kg of pure phosphorus, and 8kg of pure potassium are applied to the fore...

Abstract

The invention provides a method for interplanting jerusalem artichokes under tree crowns. The method comprises the following steps that 1, jerusalem artichoke tubers with the size of 3-5 cm are selected as jerusalem artichoke potato seeds, 1-2 bud eyes are retained, and the sterilization and seed mixing are performed; 2, soil of planting forest land is deeply ploughed and harrowed, and then fertilizers are applied; 3, in spring or autumn, the jerusalem artichoke potato seeds are sowed in the planting forest land by adopting the sowing way of burying the tubers, the spacing of the rows of the jerusalem artichoke potato seeds is 30-50 cm * 60-100 cm, and the distance between the jerusalem artichoke potato seeds and woods is 160-200 cm; 4, soil loosening and weeding are performed after jerusalem artichokes emerge, the soil is kept watered thoroughly after thorough drying; 5, harvesting is performed. The problems of high weeding cost and environment pollution caused by herbicides of the forest land are solved, high-yield and stable-yield jerusalem artichokes are obtained by reasonably selecting the interplanting way under tree crowns and optimizing a planting method, the economic benefit of forest land is improved, and development of forestry economy is promoted.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for interplanting Jerusalem artichoke under a forest. Background technique [0002] With the gradual implementation of ecological construction, forest resources are gradually enriched, providing an environmental and material basis for the development of the forest economy. However, the open space in the current forest land has not been well developed and utilized, and even barren and overgrown with weeds, the herbicides used to remove weeds pollute the soil greatly, and the cost of manual or mechanical weeding is high. Therefore, the planting mode of understory interplanting crops or Chinese herbal medicine can be adopted, which can not only avoid the waste of understory space, but also promote the interaction between the two. At present, interplanting crops in forest land are mainly some low-growing crops, such as: peanut, soybean, rapeseed, licorice, Panax noto...
