Problems solved by technology

It has been reported that the fruit cracking phenomenon is very easy to occur in the late growth period of pitaya fruit (from color change to fruit maturity stage), especially about 2 days before fruit ripening or about 5 days after ripening, which seriously affects the appearance quality and commercial value of dragon fruit fruit. It not only reduces the economic benefits of its planting, but also causes pollution to the orchard
[0003] At present, a large amount of research work has been carried out on the introduction and cultivation of dragon fruit, and major breakthroughs have been made in the seedling cultivation of dragon fruit, orchard construction, and fruit processing. few

Embodiment 1

[0040] The fruit cracking prevention method of dragon fruit described in the present embodiment is as follows: combine fertilization technology and water management method.

[0041] 1. Fertilization technology improvement:

[0042] According to the soil test results of the orchard, the pitaya cracked fruit orchards were fertilized.

[0043] (1) Base fertilizer application: After the last batch of pitaya fruits are harvested, a 20cm wide and 15cm deep trench is opened at a distance of 25-30cm from the main root, and 1700kg of peanut bran organic fertilizer, 20kg of superphosphate and 8kg of potassium sulfate are applied per mu. Foot base fertilizer;

[0044] (2) Top dressing:

[0045] Topdressing management for the first two weeks of dragon fruit flowering: topdressing calcium fertilizer through drip irrigation with water and fertilizer. The frequency of drip irrigation and fertilization is 3-5 times / month, depending on the growth period of dragon fruit and the growth status...

Abstract

The invention provides a cultivation method for preventing pitayas from cracking. The cultivation method comprises a fertilization improving method and a field water management method. The fertilization improving method comprises steps of base fertilizer applying and topdressing management. The base fertilizer applying is performed after the last batch of pitayas are harvested and base fertilizersare applied in the places which are 25-30 cm away from the main roots. The topdressing management comprises steps of two-week topdressing management before flowering phases of the pitayas and topdressing management during fruit expansion phases of the pitayas. The field water management method comprises pre-water management during fruit expansion phases and water management during fruit expansionphases. In this way, by optimizing fertilization formulas of different pitaya growth phases, and combining field water management in different growth phases, yield of the pitayas is improved, fruit cracking rate of the pitayas is reduced and economic income is improved.

Description

technical field [0001] The invention belongs to the technical field of planting crops, and in particular relates to a cultivation method for preventing dragon fruit from cracking. Background technique [0002] Dragon fruit (Hylocereusundulatus Britt) is rich in nutrients such as potassium, anthocyanins, and vitamin C, and is loved by people. At present, the scale of dragon fruit planting in my country continues to expand. The total planting area in Guangzhou has reached about 13,000 hectares. The planting area in Guangxi is about 0.8 million hectares, and Guizhou is also close to 6,500 hectares. With the expansion of planting scale, the problem of soil nutrition in pitaya orchards has become increasingly prominent. Problems such as low yield per unit area, low ratio of high-quality fruit, and physiological diseases caused by unbalanced soil nutrition are also becoming more and more serious. These production problems seriously restrict my country's dragon fruit industry. healt...
