A method for ecologically planting Peucedanum chinensis under a walnut forest

Abstract

The invention discloses a method for ecologically planting angelica decursiva in a juglans sigillata forest, and belongs to the technical field of traditional Chinese medicine planting. The method sequentially includes the following steps of firstly, selecting a land and preparing soil, wherein the juglans sigillata forest in a cold and wet area with altitude of 2500 m to 3000 m and gradient of 3 degrees to 30 degrees is selected for planting, juglans sigillata tree age ranges from 5 years to 6 years, and the spacing in rows and spacing between rows of juglans sigillata are 6 m*8 m; secondly, sowing seeds, wherein 2-2.5 kg of angelica decursiva seeds are sown per mu, sowing in lines is adopted in the sowing process, lines are pulled and bottom channels are flattened through shoveling during sowing in lines, channel depth is 3 cm, and the line spacing ranges from 30 cm to 35 cm; thirdly, conducting field management, wherein weeding, topdressing of hole applied fertilizer, seed stack picking and topping, stamen removing, drought resisting and waterlogging preventing are conducted; fourthly, harvesting angelica decursiva. Appropriate growth conditions can be provided for angelica decursiva, land in the juglans sigillata forest can be used for plantation, weeding is achieved for juglans sigillata, juglans sigillata planting cost is reduced, and dual income increase is achieved through juglans sigillata and angelica decursiva.

Description

technical field [0001] The invention relates to the technical field of planting traditional Chinese medicines, in particular to a method for ecologically planting Peucedanum chinensis under a walnut forest. Background technique [0002] Peucedanum is the dried root of Peucedanum praeruptorum Dunn or Peucedanum decursivum Maxim. It is excavated from winter to next spring when the stems and leaves are withered or the stems are not drawn, the fibrous roots are removed, washed, and dried in the sun or at low temperature. The main constituents of Peucedanum chinensis are coumarin compounds, while the characteristic components of Peucedanum chinensis are linear dihydropyran and dihydro Furan Coumarins, Procuroside (nodakenin, NDK) is the active ingredient in Peucedanum chinensis, which has anti-platelet aggregation effect. Modern pharmacological studies have shown that many procoumarin components have varying degrees of Calcium ion Antagonist activity, has the effect of dila...

Problems solved by technology

At present, the planting of soaked walnuts in Yunnan provides a good way to solve the problem of farmers in mountainous areas getting rich, but the distance between walnut plants is large, and generally only 8-10 pickled walnut trees are planted per mu, which is a waste of valuable forest resources, and walnuts are most afraid of grass. If walnuts are planted alone in the woodland, it will be more difficult to weed, which is not good for the growth of walnuts

Moreover, walnuts need top dressing during the growth period, mainly quick-acting fertilizers, such as urea, ammonium bicarbonate, and compound fertilizers. However, due to the deep root system of walnuts, the utilization rate of fertilizers is low when fertilizing, and multiple fertilizations are required to be effective. planting cost

In recent years, intercropping under walnut trees has been adopted, such as intercropping food crops. With the adjustment of industrial structure, intercropping methods such as walnut and flue-cured tobacco, walnut and vegetables, walnut and tea, walnut and P. content, but so far there is no relevant report on the intercropping of Peucedanum chinensis under the pickled walnut forest
