Abstract

The invention relates to a special fertilizer for overcoming Chinese-drug pseudo-ginseng continuous cropping obstacles. The fertilizer is formed by mixing rapeseed dregs, pig manure, active carbon, bentonite and composite nutrient. The fertilizer is specially developed to solve the problems of low rate of emergence and severe disease damage of pseudo-ginseng after the continuous cropping, finally resulting in output reduction and even total crop failure. The invention can supplement nutritive elements required for the growth of the pseudo-ginseng, improve the physicochemical properties of the continuous cropping soil, effectively adsorb autotoxic substances of the pseudo-ginseng in the soil, improve the micro-ecological environment of the soil and enhance the stress resistance of pseudo-ginseng plants, promote the normal growing development of the pseudo-ginseng plants, thereby finally greatly increasing the yield of the continuous cropped pseudo-ginseng. The invention has obvious ecological effects and economic benefits.

Description

1 technical field [0001] The invention belongs to the technical field of traditional Chinese medicine fertilizers, and specifically relates to a special fertilizer for rectifying the continuous cropping obstacle of Panax notoginseng, which can effectively alleviate the phenomenon of continuous cropping obstacle of Panax notoginseng, has no pollution to the environment, and has no damage to the Panax notoginseng plant. 2 background technology [0002] 2.1 State of the art [0003] Panax notoginseng is a rare and precious Chinese medicinal material unique to my country, which has significant effects of dispelling blood stasis and stopping bleeding, reducing swelling and relieving pain. At present, wild notoginseng is very rare, and now notoginseng is cultivated artificially. Since Panax notoginseng is a perennial plant cultivated in the shade and prefers warm and humid conditions, the ecological environment of the soil deteriorates and the obstacles to continuous cropping are...
