Embodiment

[0045] A high-quality and high-yield cultivation method of dragon fruit adopting the integrated irrigation and fertilization technology of water and fertilizer, comprising the following steps:

[0046] (1) Screening of cultivars: screen out good self-pollination dragon fruit varieties as cultivars, and said cultivars select the red-skinned red meat type variety "Big Red" introduced from Taiwan, and the self-pollination rate of this variety is as high as 90% %, the weight of a single fruit is 500-1000g, the maximum weight of a single fruit is 1200g, and the average fruit weight of more than 500g accounts for 65% of the total number, and the soluble solids are 18-20%. Indexes such as fruit rate and fruit quality are higher than the current main varieties;

[0047] (2) Nursery stock cultivation: Cut the green stems that have grown 150-380d and 15-30cm long from the selected cultivars, and use them as stems for cutting seedlings; Cut off the fleshy stem to expose the round xylem ...

Abstract

The invention discloses a pitaya high-quality and high-yield cultivation method adopting a water and fertilizer integrated fertigation technology. The method comprises the steps of screening of cultivated varieties, seedling cultivation, soil preparation, planting line and belt fabrication, bent frame building with stand columns, trickle irrigation system laying, plastic film mulching, seedling planting, irrigation, fertilization, trimming, clipping, flower thinning, fruit sorting, pest control, plastic film mulching for protection against frost and the like. According to the method, the pitaya variety of a self-pollination type is adopted as the cultivated variety, the fence planting mode and the fertigation technology are adopted, the investment in labor cost such as in pollination, weed control and fertilization is greatly saved, the lighting effect for pitaya is improved, the fertile fruit percentage is effectively raised, the fruit quality is effectively improved, the fertilizer using efficiency is raised to the maximum extent, the input-output cycle is short, the output is high, and the pitaya cultivation technology is worthy of being promoted widely.

Description

technical field [0001] The invention belongs to the technical field of dragon fruit cultivation, and in particular relates to a high-quality and high-yield cultivation method for dragon fruit by adopting the integrated water and fertilizer irrigation and fertilization technology. Background technique [0002] Pitaya is native to Brazil, Mexico and other places in Central America. It belongs to the cactus family. Its fruit is rich in water-soluble anthocyanins, vitamins, mineral elements and dietary fiber. Protein, which can remove some heavy metal ions in the human body, has high nutritional and economic value. At present, commercial cultivation has been realized in countries such as Nicaragua, Colombia, Israel, Vietnam and China. Taiwan, Vietnam, and Thailand are the main production areas in Asia. The introduction and planting of the country began in the 1990s. The red-skinned and red-flesh varieties introduced are basically varieties that require artificial pollination. S...
