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 ...
