Abstract:  In order to improve the pineapple mechanized planting ability, based on the analysis of the existing fruit and vegetable transplanting technology and pineapple planting technology, a 2ZBL-90 double row pineapple planter was designed and trial produced, which can complete the fertilization, rotary tillage, ridging, film mulching, transplanting, and other operation procedures for pineapple seedlings at one time. The morphological parameters of pineapple seedlings were measured and statistically analyzed, the key components of fertilization and rotary tillages and transplant parts were optimized. The results showed that the length of pineapple seedling was 15-30 cm, the width was 10-15 cm, the conic angle of seedling type was 21°-30°, the diameter of spiral blade was 100 mm, the pitch was 60 mm, and the rotation speed was controlled at 15 r/min. The planting spacing and depth of the 2ZBL-90 pineapple seedling transplanter met the planting requirements. The qualified rate was more than 95%, and the seedlings were in a good upright state, which could meet the planting requirements.
