Problems solved by technology

However, due to the high cost of planting Panax notoginseng and the long growth cycle, it takes at least 3 years to complete a round of evaluation. Once it is not suitable for planting, the loss will be huge

Embodiment Construction

[0061] The present invention verifies the effect of the provided evaluation method through specific examples. details as follows:

[0062] Step 1: Evaluate the effects of biotic and abiotic factors in the understory soil on the growth of Panax notoginseng

[0063] In 2016, Simao pine forest vegetation was selected in Lancang and Ning'er, Yunnan pine forest vegetation was selected in Wenshan, Diqing, Lijiang and Jianshui, miscellaneous wood forest vegetation was selected in Banna, and eucalyptus forest vegetation was selected in Lancang, as shown in the table 1. Remove impurities on the soil surface, and take 0-30cm soil layer soil. Select 10 points for sampling in each area, and the distance between each point is more than 100m. Take 6 soils from each point, remove the plant residues in the soil, mix them thoroughly and bring them back to the room and store them in a 4°C refrigerator for later use.

Abstract

The invention relates to an evaluation method for an understory environment applicable to planting of pseudo-ginseng, belonging to the field of crop cultivation. According to the invention, a forest plant generates a mutual generation or constraining effect to foreign plants mainly through root exudates, volatile matters and understory special soil microorganisms to affect the understory growth ofplant populations. Thus, the invention provides a method for rapidly evaluating whether released allelopathic substances and formed special soil by different tree species are applicable to the growthof the pseudo-ginseng or not, and for determining whether forest vegetation is applicable to planting of the pseudo-ginseng or not through rapid analysis of influence of volatile matters, leaching matters, understory special soil microorganisms and abiotic factors on the growth of the pseudo-ginseng; and the invention also provides a judgment method for influence on the growth of the pseudo-ginseng. The method provided by the invention only needs three months to complete the whole process of evaluation, so the forest vegetation applicable to planting of the pseudo-ginseng can be rapidly selected.

Description

technical field [0001] The invention belongs to the field of crop cultivation, relates to the field of notoginseng planting, and in particular relates to an evaluation method for an under-forest environment suitable for notoginseng planting. Background technique [0002] Panax notoginseng is a traditional precious Chinese medicinal material in my country, which has the effects of reducing swelling, relieving pain, promoting blood circulation and removing blood stasis. At present, Panax notoginseng is mainly planted in the farmland by means of shading cultivation. However, due to serious obstacles to continuous cropping, the area of ​​farmland that can be used for planting Panax notoginseng in authentic areas is decreasing year by year, which greatly limits the normal production of Panax notoginseng. In addition, because farmers only pay attention to the yield and ignore the quality in the production of Panax notoginseng, the use of a large amount of pesticides and chemical f...
