A method for fertilizing the aerial roots of a single-column dragon fruit

Abstract

The present invention relates to the technical field of pitaya cultivation, in particular to a single-column method for fertilizing the aerial roots of pitaya. The special feature is: during the period from mid-to-late May to the end of October in the first year of planting, the aerial roots are sprayed every 10 days. Apply nutrient solution A once; during the period from the end of April to the end of October in the second year of planting, spray nutrient solution B to the aerial roots every 15 minutes; the nutrient solution A includes by weight percentage: potassium dihydrogen phosphate 0.1%-0.3 %, 0.1%-0.3% of borax, 0.2%-0.4% of urea; the nutrient solution B includes by weight percentage: 0.1%-0.3% of potassium dihydrogen phosphate, 0.1%-0.3% of borax, 0.6%-0.8% of zinc fertilizer %, molybdenum fertilizer 0.6%-0.8%, by cultivating the aerial roots on the branches of the dragon fruit, spraying the nutrient solution, allowing the aerial roots of the dragon fruit to fully absorb nutrients, making the branches of the dragon fruit strong and increasing the yield.

Description

technical field [0001] The invention relates to the technical field of pitaya cultivation, in particular to a single-column method for fertilizing pitaya aerial roots. Background technique [0002] Dragon fruit originates in Mexico and other Central American tropical rainforest areas, mainly in Central and South America and Vietnam. Its fruit is huge, the peel is bright red, the flesh is white or blood red, the flesh is smooth, sweet but not greasy, it has medicinal value and health care function. Studies have shown that vitamin C and anthocyanins in dragon fruit have anti-aging and reduce heart disease, The role of the incidence of cancer; the fruit, flowers and stems of dragon fruit are rich in high-quality plant protein, which has obvious detoxification function for heavy metal pollution in the human body; medical experts have also found that dragon fruit has the effect of lowering blood fat and blood sugar. , lower blood pressure, prevent arteriosclerosis and other heal...

AI Technical Summary

Problems solved by technology

[0003] Pitaya is a plant of the genus Pyrex in the family Cactaceae. There is no strong upright trunk. The trunk is a fleshy stem with underdeveloped xylem. Therefore, the main branch of dragon fruit needs to be attached to the support frame to grow normally. At present, the types of supports used in production are mainly Single-column and A-type rack-type; the advantages of single-column planting dragon fruit are independent cultivation, no need to consider planting direction and terrain, good ventilation and light transmission, and slow spread of diseases and insect pests, such as CN201420331276.3 and CN201420331555.X A single-column planting frame is disclosed, but the disadvantages are that the quality of the cement column is heavy, the labor cost for garden construction is high, and the output is low; the advantages of the A-type bent-type planting dragon fruit are that the garden construction cost is low, and the results of the branches are wide. High yield per unit area, such as CN201510348540.3 discloses row-type planting racks, but the disadvantage is that the cultivation density is high, its ventilation is poor, it is not conducive to the prevention of pests and diseases, and the growth of branches is difficult to control. pruning, increasing manual labor output

[0004] And the cultivation of aerial roots has not been paid attention to in the prior art, although CN201610203263.1 discloses a kind of method that pitaya aerial roots guide as main root and CN201610055311.7 discloses a kind of method that artificially induces the new aerial root germination of pitaya , but the processing operation is cumbersome, and the use of a large amount of disinfectant solution causes toxic components to remain
