Method for cultivating Dragon fruit in greenhouses in North China

Abstract

The invention provides a systematic and standard method for cultivating Dragon fruit in greenhouses in North China. The method comprises the steps of selection of sunlight greenhouses with good thermal insulation performance, fielding planting, field management and the like. The method provided by the invention is appropriate to standardized dragon fruit cultivation in greenhouses in North China,and has the benefit that the existing greenhouse conditions of North China are utilized to cultivate tropical and subtropical fruit trees so as to enrich the variety of crops cultivatable to facilities in North China. Dragon fruit grown according to the method provided by the invention has plump branches and smooth and juicy flesh, and has the advantages of elegant shape, excellent color, sweet flavor, good taste and high output.

Description

technical field

[0001] The invention relates to a method for cultivating tropical fruit trees in a northern greenhouse, in particular to a method for cultivating dragon fruit in a northern greenhouse. Background technique

[0002] Pitaya is a plant of the genus Trigonidae in the family Cactaceae. It is native to the tropical desert areas of Central America such as Mexico and Brazil. It is a typical tropical plant. At present, in some countries in Central America and South America, and Vietnam in Asia, there are relatively large-scale plantations. The cultivation history of dragon fruit in my country is relatively short. At present, it has only emerged in some provinces and regions such as Taiwan, Hainan, Guangxi, Guangdong, and Fujian. The cultivation area is still very limited. The current cultivation area is about 5,000 mu, forming a huge gap between supply and demand. The development prospect of dragon fruit is very broad.

[0036] 1. Plan the plantation of dragon fruit

[0037] Choose a solar greenhouse with good thermal insulation performance. Dragon fruit has wide adaptability to soil, and can be planted in general soil, but it grows fast, has high yield and good quality in loam soil that is loose and air-permeable, well-drained, strong in water and fertility, and rich in organic matter. Use 5% wood vinegar solution or 0.3% ferrous sulfate solution to adjust the soil pH to 7.0. Generally, it is necessary to replace the soil in planting rows, and the nutrient soil can be prepared according to the weight ratio of pe...
