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

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...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention takes water and fertilizer integrated irrigation and fertilization as the key high-quality, high-yield technology, and through the optimization of planting techniques such as variety screening, seedling cultivation, planting management, etc., a method of using water and fertilizer integrated irrigation is proposed. The high-quality and high-yield cultivation method of dragon fruit with fertilization technology, which solves the problems of large labor consumption, low fertilizer utilization rate, low yield, poor quality, and input-output failure in the conventional column cultivation method.
