Pitaya high-quality and high-yield cultivation method adopting water and fertilizer integrated fertigation technology

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.
