Embodiment 1
[0020] A cultivation method for interplanting rhubarb under a walnut forest, comprising the steps of:
[0021] 1) Woodland selection: Choose a walnut forest at an altitude of 1200m, facing south, with good shading effect and a large canopy. The frost-free period is 160 days, the average annual precipitation of the walnut forest is 1100 milliliters, and the light transmittance is ≤45%. If the light rate is less than 35%, the light transmittance of the stand should be controlled between 35% and 45% through thinning and pruning;
[0022] 2) Rhubarb planting: clean up the dead branches and leaves in the forest, and collect them in the warehouse. Deeply plow the land twice, first vertically and then horizontally, and plow into the soil together with the nutrient base and organic fertilizer; Then the rhubarb seeds are drilled according to the row spacing of 85cm, the plant spacing of 75cm, and the depth of the sowing ditch of 5cm. 2 35 days after rhubarb sowing, interplant ryegrass...

[0032] A cultivation method for interplanting rhubarb under a walnut forest, comprising the steps of:
[0033] 1) Woodland selection: Choose a walnut forest at an altitude of 1800m, facing south, with good shading effect and a large canopy. If the light rate is less than 35%, the light transmittance of the stand should be controlled between 35% and 45% through thinning and pruning;
[0034] 2) Rhubarb planting: clean up the dead branches and leaves in the forest, and collect them in the warehouse. Deeply plow the land twice, first vertically and then horizontally, and plow into the soil together with the nutrient base and organic fertilizer; Then the rhubarb seeds are drilled according to the row spacing of 95cm, the plant spacing of 85cm, and the depth of the sowing ditch of 7cm. 2 40 days after rhubarb sowing, alfalfa was interplanted, and the area ratio of green manure crops and rhubarb was 1:5; the nutrient base A was composed of the following raw materials by weight: 68 ...
