Description
Technical Field
The invention relates to the technical field of dragon fruit planting, in particular to a method for planting single-column double-layer dragon fruits.
Background
Pitaya is a cultivar of a Petasites hybridus of Petasites of Cactaceae, and has fleshy shrub with aerial root. The dragon fruit not only has fragrant and sweet taste, but also has high nutritive value, and integrates the advantages of fruits, flower buds, vegetables and medicines. The fertilizer is rich in nutrition, unique in function, few in plant diseases and insect pests, and capable of growing normally almost without any pesticide. Therefore, the dragon fruit is a green and environment-friendly fruit and health-care nutrient food with definite curative effect. The pitaya is sweet and mild in nature, and the main nutritional ingredients of the pitaya include protein, dietary fiber, vitamin B2, vitamin B3, vitamin C, iron, phosphorus, calcium, magnesium, potassium and the like. It is rich in pulp fiber, carotene, vitamins B1, B2, B3, B12, C, etc., and the kernel (black sesame seed) contains rich mineral matters such as calcium, phosphorus, iron, etc., various enzymes, albumin, cellulose and high-concentration natural pigment anthocyanin (especially red meat), and the flower, stem and tender bud have various effects similar to those of the close (aloe). In recent years, the dragon fruits are deeply loved by consumers, the market demand is greatly improved, the planting area of the dragon fruits in China is enlarged, and a lot of agriculture is carried out on a large scale.
For a long time, the traditional clearing and plowing soil preparation management mode is adopted in the dragon orchard, so that the soil properties are changed, the fruit yield is reduced, and the quality is deteriorated. Local planting, most of cultivation frames of dragon orchards mainly adopt a support mode, and a traditional clear tillage soil preparation management mode is combined, so that the cultivation space utilization rate is low, tree shapes are inconsistent, branches are messy, soil characters are poor, the yield of fruits is reduced, and the quality of the fruits is poor. The single-column type dragon fruit cultivation frame is the basis of a high-quality and high-yield dragon fruit cultivation mode generally promoted in regions such as Taiwan China and the like for high-yield dragon fruits, and brings considerable ecological and economic benefits for planting the dragon fruits. In recent years, some enterprises have gradually introduced a single-column type dragon fruit cultivation shelf in taiwan, and developed many research designs in the aspect of the dragon fruit cultivation shelf, but because further research and optimization cannot be performed on the dragon fruit cultivation shelf according to local conditions, and the dragon fruit cultivation management and protection mode is improved and updated in combination with local planting conditions, the dragon fruit cultivation benefit is not obvious, and even the fruit quality is affected.
