Process method for continuous cropping soil of Panax Notoginseng

Abstract

The invention belongs to the cultivation technology of Chinese herbal medicines, and relates to a process method for the continuous cropping soil of Panax Notoginseng. The process method specifically comprises the following steps: (1) after the collection of Panax Notoginseng in July-August (the collection of the winter Panax Notoginseng is in December), immediately clearing the plant residues, such as Notoginseng stems, leaves, hair roots and the like, in the furrows, removing the covering materials, such as mulching film, straw, cogon or pine needle, on the surface of the furrows; (2) broadcasting 9000-13500 kg of crushed rape-seed meal per hectare, intertilling the land by artificial or mechanical method, ploughing the rape-seed meal under the soil in the furrows evenly; (3) irrigating enough water to the furrows in the Notoginseng shed so that the soil in the shed reaches the saturated state of water intake; (4) covering the furrow surface in the Notoginseng shed by an unbroken plastic thin film whose peripheries are tamped down by heaping the soil to prevent contact with air; (5) recovering the thin film till November (the field of the winter Panax Notoginseng is in next December), turning over the soil, and planting the Panax Notoginseng anew in December. The invention overcomes the Panax Notoginseng continuous cropping obstacles to a certain degree, has no pollution to the environment, provides organic fertilizer for the growth of Panax Notoginseng better, and has good social, ecological and economic benefits.

Description

1 Technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, and specifically relates to a soil treatment method for continuous cropping of notoginseng. 2 background technology [0002] 2.1 State of the art [0003] Panax notoginseng is a rare and precious Chinese medicinal material unique to our country, which has significant effects of dispelling blood stasis and stopping bleeding, reducing swelling and pain. Panax notoginseng is mainly distributed in Wenshan Prefecture of Yunnan and Baise area of ​​Guangxi. At present, wild Panax notoginseng is very rare, and Panax notoginseng is cultivated artificially. Due to the large-scale single planting year after year, and the fact that Panax notoginseng is a perennial plant that is cultivated in the shade, and likes warm and humid, the soil ecological environment deteriorates and the problem of continuous cropping is serious. Investigations have shown that it takes about 8-10 years to r...

Problems solved by technology

[0008] The obstacle of continuous cropping of Panax notoginseng is quite serious. At present, the method of soil chemical sterilization is mostly used to control it, but this method has potential risks such as pesticide residues and environmental pollution.

In addition, the chemical fertilizers commonly used in the cultivation of Panax notoginseng can hardly meet the balanced and continuous demand for nutrients of Panax notoginseng
