Method for intercropping rhizoma bletillae and aplotaxis auriculata

The invention relates to a method for intercropping rhizoma bletillae and aplotaxis auriculata, belonging to the technical field of Chinese medicinal crop cultivation. The method comprises the following steps: fertilizing 30000-45000kg/hm of well-rotted farmyard manure and 225-450kg/hm of compound fertilizer during soil preparation; making ridges along the south-north direction; planting aplotaxis auriculata seeds and rhizoma bletillae corms between March and April every year at the same time, planting the rhizoma bletillae corms on the ridge surface with the width of 30-50cm along the east-west direction, and then planting the aplotaxis auriculata on the rest ridge surfaces, wherein the spacing in the rows of the rhizoma bletillae corms is 8-10cm*10-15cm, and the seed dosage is 500-600kg/hm ; bunch planting the aplotaxis auriculata in a triangular form, wherein the hill spacing is 10-20cm*20-30cm, and the seeding rate is 12-15kg/hm ; and topdressing for four times in the first and second years of planting.
