In the past, the cultivation of pineapple was used for planting. One cycle of production was about 10 years from colonization to renewal, and the annual average yield per acre was about 1000 kilograms. In order to obtain such output, it is also necessary to sparse seedlings every year, applying heavy fertilizer, large earthwork, and more flower workers, which have high costs and are not convenient for mechanized operation. In order to adapt to the new production conditions, shorten the production cycle, increase pineapple yield, I
