The present invention relates to a sparse planting method of pineapple
sugar-apple fruit in dry and hot valley areas, and belongs to the technical field of
fruit tree cultivation. The present invention comprises the following steps: S1, constructing a water platform land according to the
topography in the dry and hot valley areas; S2, mixing sheep
manure,
lime and tobacco leaves in a ratio of 15-20:1:3 to improve the soil of the water platform land; S3, using seedlings to sparsely
plant along the
contour line in the quasi-water platform land, and timely
spray irrigation; S4, in February of the second year after the survival of the seedlings, scion
grafting, sheep
manure,
lime, tobacco leaves,
calcium magnesium phosphorus, and compound
fertilizer are applied 4 times in the four seasons of each year, and the
young tree shape is arranged in combination with windproof measures, and a regular and full tree crown is cultivated; S5, when the seedlings begin to bear fruit, combined with soil reform fertilization, production period adjustment, artificial
pollination, fruit period management, fruit bagging, fruit harvesting management and
pest control are carried out in batches. The present invention greatly improves the yield and quality of pineapple
sugar-apple fruit in dry and hot valley areas, and improves the slope utilization value of dry and hot valley areas.
