There are two rows, three rows and four rows of pineapple cultivation methods. Two-line type, commonly used sulcus and ditch 150cm wide, double row single plant arrangement. Its advantages are that the wider fibrous roots of the sulcus can expand outwards, the spacing of the pods on the rake is relatively uniform, the stem bases are pressed against each other, and the leaves expand into hemispheres, which can make full use of sunlight, and can easily form the “self-shadowed†environment between the rows. Reduce sewerage weeds and facilitate management. Planting pineapple in this way generally has a groove width of 100-110cm and a small row spacing of 40-50cm. The plant spacing varies with the density. If 3500-4000 strains are planted per 667m2, plant spacing is 20cm, 4500 strains are planted per 667m2, and plant spacing is about 15cm. The three rows of single plants arranged in a total of 170cm in width and width, in which the surface width of 120cm, small spacing 35-40cm, plant spacing with density, usually between 20-25cm, in this way, individual plant nutrient area is uniform. Four-line type, generally 200cm wide, narrow and wide rows of planting, width 100cm (including groove width 50cm), narrow row 50cm (including groove width 20cm), the formation of the small plant surface is planted with 25cm spacing, every 667m2 planting 4500-5000 strains. Its advantages are: there is a ditch on the raft, and after the plants are sealed, the ditch is both drained and water-retaining, which favors the growth of the root system; the large row spacing is wider to facilitate the pedestrians' operation, and the narrow rows of blades on both sides are subject to less human damage, and the leaf blades are more vulnerable to frost. In order to alleviate, the big fruit is obtained in the middle of these two lines.
After the end of the process, such as basal fertilization and picking and digging trenches, it is better to lay a layer of grass on the surface when conditions permit, to enhance the ability to retain water and fertility, and also to suppress weeds. The selected seedlings are then placed on the plant surface and colonized at a predetermined density. Seedlings must be kept shallow. Depth of planting: top buds, shoots buds 2-3cm, 3-5cm buds, seedlings growing point exposed to the ground, too shallow to be easily blown by the wind, not easy to grow roots; seedlings too deep affect rooting Ye, even years are hard to come to fruition. Each plant should be as flat as possible without skewing.
For mechanized farms, a series of implements such as tractors for hauling, fertilizing, picking, picking, filming, and pressing holes are used before the planting to complete standby; before planting, the seedlings that have been divided into good grades are manually inserted into the holes. Can be within.
