Embodiment 1

[0031] A method for eliminating obstacles to continuous cropping of Salvia miltiorrhiza provided by a preferred embodiment of the present invention, the specific steps are as follows:

[0032] (1) Harvest Salvia miltiorrhiza in mid-January, dig out the root of Salvia miltiorrhiza and remove the stubble of Salvia miltiorrhiza, rid the soil, apply 15kg of urea per mu, and 25kg of compound fertilizer. The height is 15cm, the ridge distance is 25cm, and the ridge is flat;

[0033] (2) Apply basal fertilizer at the beginning of March, plant ginger, and harvest in September;

[0034] (3) In mid-September, the ginger residues in the soil were cleaned, and the corn stalk powder processed into a powder with a particle size of less than 2 mm was evenly turned into the soil with a rotary tiller. The depth of tillage was based on the plowing layer.

[0035] (4) From mid-September to mid-October, irrigate the soil with water to saturation and cover it with 0.3mm plastic film. After 15 day...

Abstract

The invention discloses a method for eliminating obstacles to continuous cropping of salvia miltiorrhiza, comprising the following steps: S1. Harvest salvia miltiorrhiza in mid-January, and then ridge and mix the soil with fertilizer; S2. Plant ginger on the fertilized soil in early March, and harvest in September; S3. From mid-September to mid-November, carry out strong soil reduction soil treatment; S4. In mid-November, ridge the soil and mix a small amount of fertilizer; S5. In early December, plant the next crop of Salvia miltiorrhiza seedlings. The present invention adopts the method of salvia-ginger crop rotation and strong reduction soil treatment, adjusts the soil micro-ecological environment while realizing rapid improvement of soil fertility, reduces the amount of fungicides and pesticides and chemical fertilizers, increases the output and quality of salvia miltiorrhiza, and is a benign development of the salvia miltiorrhiza industry. Cycle provides technical support.

Description

technical field [0001] The invention belongs to the technical field of salvia miltiorrhiza planting, and in particular relates to a method for eliminating obstacles to continuous cropping of salvia miltiorrhiza. Background technique [0002] Zhongjiang County, Sichuan is one of the main producing areas of Salvia miltiorrhiza in my country. It has a long history of cultivation. The artificial cultivation of Salvia miltiorrhiza began in Zhongjiang County, Sichuan. Deformed, with cracked roots. With the increase of the continuous cropping period of salvia miltiorrhiza, it is also accompanied by land degradation problems such as soil acidification, salinization and soil compaction. Moreover, soil-borne diseases are serious, and major diseases such as root rot, fusarium wilt, red leaf disease, and disease frequently appear in Salvia miltiorrhiza. This directly endangers the growth of the next plant, reduces the active components, deforms the appearance of the root system, causes...
