specific Embodiment approach 1
[0037] Specific embodiment one: the present embodiment is a kind of cultivation method for intercropping of multi-season roses and dandelions for returning farmland to forest, specifically according to the following steps:
[0038] 1. Choose a well-drained, fertile and loose plot; the plot is loam or sandy loam;
[0039] 2. Deep plow the land in autumn, and apply 600-800kg / mu of decomposed organic fertilizer. In spring, rotary tillage is used to make ridges, with north-south ridges, flat ridges, and finely crushed soil;
[0040] 3. Select 2-3 years multi-season rose seedlings, remove diseased branches and residual branches, keep 10-12cm of underground root system, and obtain multi-season rose seedlings to be planted;
[0041] 4. Select dandelion seeds with good varieties and strong disease resistance, soak them in warm water with a temperature of 40-45°C for 5-5.5 hours, and obtain dandelion seeds to be sown;
[0042] 5. Dig a transplanting pit on the ridge made in step 2, cont...
specific Embodiment approach 2
[0048] Embodiment 2: This embodiment differs from Embodiment 1 in that: in Step 1, the organic matter content of the plot is >1.5 mg / kg. . Others are the same as in the first embodiment.
specific Embodiment approach 3
[0049] Embodiment 3: This embodiment is different from Embodiment 1 or 2 in that: in step 2, the depth of deep plowing is 22-30 cm, and the upper layer of soil is controlled to be loose, and the lower layer of soil is compacted. Others are the same as in the first or second embodiment.

Abstract
The invention relates to the field of commercial crop cultivation in farmland returned to forests, in particular to a rosa rugosa and dandelion intercropping cultivation method for returning farmlandto forests and aims to solve the technical problem of labor cost increasing due to high quantity of weeds in exposed land under rosa rugosa. The method includes land selection, land preparation in autumn, high-quality seedling and seed selection and pretreatment, timely transplanting of rosa rugosa, dandelion planting, covering with straw mats, timely watering, field management, dandelion final singling and water-fertilizer management. On the basis of spatial structural complementation of rosa rugosa and dwarf dandelions, row spacing optimization is performed for facilitating ventilation and light transmission to make full use of field light rays, and efficient utilization of natural resources such as light and heat is realized; further, by ground coverage of the dandelions, growth of weeds under rosa rugosa can be reduced, and economic benefits are increased while water and soil loss is reduced. The cultivation method is applied to the field of returning farmland to forests.
Description
technical field [0001] The invention relates to the field of economic crop cultivation methods for returning farmland to forest land. Background technique [0002] The concept of returning farmland to forests is to protect and improve the ecological environment, stop farming on sloping farmland that is prone to soil erosion in a planned way, and plant trees according to local conditions in accordance with the principle of suitable trees for the right place. Therefore, it is necessary to select appropriate tree species and planting methods for the plots of returning farmland to forests, so as to achieve economic benefits and at the same time prevent soil erosion to the greatest extent. [0003] Dandelion is a Compositae plant. It not only contains the general nutritional components of plants, but also contains high Vc, carotene and the necessary macro and trace elements K, Ca, Mg, Na, P, Fe, Ze, Mn, Cu Wait, the nutritional value is high. It has always been a wild vegetable...
