Embodiment 1

[0073] A method for planting bellflower intercropping without pollution and reducing the obstacle of bellflower continuous cropping, the specific steps are as follows:

[0074] 1) Land preparation and transplanting

[0075] (1) The land is prepared to select the bellflower field that has been continuously cropped for 4 years; 2-3 days before Qingming, mix evenly according to the ratio of 10kg of conventional urea and 10kg of potassium sulfate per mu, spread the ground, and then deep turn it into a high border: the height of the border is 15cm, the border surface 100cm wide, 20cm furrow spacing;

[0076] (2) Planting and transplanting Horizontally ditch on the high border to plant platycodon grandiflorum and green onion. Green onions are planted in the first row, and then planted according to the row ratio of 4 rows of bellflowers and 1 row of green onions. The specific planting is as follows: after Qingming, 20 kg of controlled-release urea, 22 kg of superphosphate, 28 kg of ...

Abstract

The invention discloses a platycodon grandiflorum intercropping planting method capable of reducing continuous cropping obstacles of platycodon grandiflorum in a pollution-free mode. In the method, the platycodon grandiflorum and green Chinese onion are intercropped, part of base fertilizers are broadcasted in the soil preparation process, part of base fertilizers are combined with pesticidal and antibacterial agents and then subjected to deep placement during transplanting of the platycodon grandiflorum, and special targeted treatment is conducted in the growth period of the platycodon grandiflorum. In this way, the continuous cropping obstacles of the platycodon grandiflorum are reduced, the yield and quality of the platycodon grandiflorum are improved, and pollution-free cultivation is achieved.

Description

technical field [0001] The invention relates to the technical field of planting Chinese herbal medicines, and relates to a pollution-free method for planting platycodon grandiflorum intercropping and reducing obstacles to continuous cropping platycodon grandiflorum. Background technique [0002] Campanulaceae (plantycodon grandiflorum (Jcaq.) A.DC) is a perennial herbaceous plant of Campanulaceae. It is an important edible, medicinal, ornamental and multi-purpose economic plant in China. It is mainly produced in Shandong, Anhui, Inner Mongolia, Jilin and other places. Platycodon grandiflora has simple cultivation techniques and high planting benefits. Driven by economic benefits, the planting area of ​​Platycodon grandiflorum is expanding year by year, and continuous cropping is inevitable. The direct consequence of the continuous cropping of platycodon grandiflora is poor growth, low yield and quality decline in the continuous cropping fields. In order to overcome the obs...
