Dragon fruit root-restricting cultivation method

Abstract

The invention discloses a dragon fruit root-restricting cultivation method. According to the dragon fruit root-restricting cultivation method, root-restricting holes are formed in land for planting in a dug mode and are round pits; non-woven fabric root-restricting bags made in advance are laid in the root-restricting holes, and small square holes are formed in the middle positions of the root-restricting bags; dragon fruit piles penetrate into small holes formed in the bottoms of the root-restricting bags; nutrient soil of the root-restricting bags is made by evenly mixing garden soil, thoroughly decomposed oriental white oak shells (or sawdust, plant ash and the like) and a farmyard manure with the water content of 30%-40% according to the volume ratio of 2 to 1 to 1 and is put into the root-restricting bags in a filled mode; seedling stems are bound on concrete columns after shallow planting, and thin soil coverage is performed after fixed planting. The dragon fruit root-restricting cultivation method is stronger in fertilization purposiveness and controllability, can effectively avoid fertilizer efficiency delaying and nutrient loss, can achieve automatic and accurate quantification of fertilizer and water supply, has an important application value in water-saving agriculture in southwest drought water-deficient areas and can effectively improve the soil organic matter content per unit area and reduce the cost required for soil improvement at the earlier stage of orchard construction.

Description

technical field

[0001] The invention relates to the technical field of fruit tree cultivation, in particular to a root-limited cultivation method for dragon fruit. Background technique

[0002] Dragon fruit is a tropical and subtropical fruit. It is drought-resistant, high-temperature-resistant, light-loving, and has low requirements on soil quality. The most suitable soil pH value is 6.0-7.5. It is best to choose land with rich organic matter and good drainage for planting. There are various planting methods for dragon fruit, which can be hedged or trellised, but column cultivation is the most common. The so-called column cultivation is a cultivation method in which a cement column or a wooden column is erected, 3~4 dragon fruit seedlings are planted around the column, and the dragon fruit plants grow upward along the column. The general planting time of dragon fruit is from March to April, and the turnaround time is from October to November. It begins to bloom and bear fr...
