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 of continuous cropping of salvia miltiorrhiza. The method includes the following steps: S1. harvesting salvia miltiorrhiza in mid-January, and then ridging soil and mixing the soil with fertilizer; S2. planting raw ginger in the soil after fertilization in early March and harvesting the raw ginger in September; S3. conducting soil strong reduction soil treatment from mid-September to mid-November; S4. ridging the soil and mixing the soil with a small amount of fertilizer in mid-November; and S5. planting the next crop of salvia miltiorrhiza seedlings in early December. The invention adopts salvia miltiorrhiza-raw ginger rotation cropping and strong reduction soil treatment methods, so that can realize the rapid improvement of soilfertility while regulating the soil micro-ecological environment, thereby reducing the application of bactericides and pesticide fertilizer, and increasing the yield and quality of salvia miltiorrhiza. Therefore, the invention provides technical guarantee for the benign circulation of salvia miltiorrhiza industry.

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...
