Planting method of bee sugar plums in karst areas

Abstract

The invention discloses a planting method of bee sugar plums in karst areas. The planting method includes the steps: deeply plowing a land before planting, and applying fermented rotten organic fertilizers; selecting bee sugar plum seedlings with strong tree vigor; planting the seedlings according the density of 5m row spacing and 3m plant spacing in spring; additionally applying fermented rotten organic fertilizers once after the autumn in October of each year; pruning according to an open-center shape when the distance between the bee sugar plum and the ground is 70-90cm, cutting and determining a trunk, selecting 3-4 branches to serve as main branches from newly-growing branches from the same year determining the trunk in spring of the second year, angles among the branches are 45-60 degrees, respectively selecting 1-2 angles from each main branch to open in spring of the third year, cutting one-third-one half of complete strong grown branches, and taking the cut branches as secondary long branches of the main branches; configuring April plums according to the proportion of 6:1. The proportion of the bee sugar plums to the April plums is 6:1, the flowering period of the April plums is basically consistent with that of the bee sugar plums, and pollen affinity of the April plums is high. The planting method is simple to operate, the bee sugar plums are high in survival rate and suitable for popularization and application in the karst areas, and yield is improved by 20-30%.

Description

technical field [0001] The invention relates to a method for planting bee sugar plums in karst areas. Background technique [0002] Fengtang plum is a variety of Fengtang plum that has been planted and bred for many years in the karst area of ​​Guizhou. Its saplings are stronger and upright, and the adult trees are more open. , long internodes; annual branches brown sun, shade green, perennial branches taupe. The leaves are narrowly lanceolate, 7.9 cm long, 2.25 cm wide, dark green, with acute tip, narrow cuneate base, finely serrated leaf margin; petiole 0.8 cm long, petiole and main vein light pink. Corolla diameter 1.4 cm, petals 5, white, filaments white, style light green, calyx light brown green. [0003] At present, in the karst mountainous area, the planting method of bee sugar plum is mainly to prune the branches according to the natural happy shape according to the row spacing of 4m×3m; [0004] Although the above planting methods have achieved certain results i...
