Planting method of hylocereus undatus

Abstract

The invention relates to a planting method of hylocereus undatus, which belongs to the technical field of fruit tree planting. The planting method comprises the following steps: (1) selecting land andbuilding a garden: selecting flat ground, hillside or sandy land with loose, ventilated and well-drained soil as garden, planting in a columnar cultivation method, wherein the column spacing is 2*2m,and the column height is 2m; and when in planting, a seedling of hylocereus undatus is 10 to 12cm away from the column, and two seedlings of the hylocereus undatus are planted surrounding each column; (2) applying fertilizer: performing the fertilizer application during the sprouting period of new shoots in Spring and during the fruit expansion period, and applying 20 to 25kg of special fertilizer for the hylocereus undatus for each plant every year; (3) managing water: keeping the soil of the garden wet during the seedling growth period; watering in spring and summer for multiple times, enabling roots to keep vigorous growth state, and keeping the soil wet during the fruit expansion period; and (4) harvesting at an appropriate time: when a fruit is full and round and has glossiness, canharvest the fruits. By adopting the planting method of the invention, the yield of the hylocereus undatus is increased, and a product meets the requirements of selenium-rich and green pollution-free organic food.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit tree planting, in particular to a planting method of dragon fruit. 【Background technique】 [0002] The important physiological functions of selenium on the human body have attracted more and more attention from scientists from various countries, and all countries have formulated recommended intakes of selenium nutrition according to their own conditions. The recommended daily intake (RDI) of selenium for adult healthy men and women in the United States is 70 μg / day and 55 μg / day, respectively, while that in the United Kingdom is 75 μg / day and 60 μg / day. The adult intake recommended by the Chinese Nutrition Society is 50-250 micrograms per day. [0003] Selenium in the human body is mainly obtained from daily diet, therefore, the content of selenium in food directly affects people's daily selenium intake. The selenium content of food is greatly affected by geography, and the difference of seleniu...

Problems solved by technology

[0007] At present, there are many problems in the planting process of dragon fruit. Fertilization is usually to directly purchase chemical fertilizers on the market as the main fertilizer, coupled with animal manure, etc., instead of using natural green fertilizers as the main material, so yellow-skinned fruit trees The quality of the

[0008] Although there is also the technology of using green fertilizers in the prior art, the effect is not very satisfactory, and the fertility is often not enough to support the rapid growth of dragon fruit, so it is often necessary to apply additional inorganic fertilizers

[0009] For now, chemical fertilizers and pesticides have been used in large quantities for a long period of time, causing the soil organic matter to decompose quickly, so the content of soil organic matter gradually decreases, and the soil quality also declines. and pesticide residues, which cannot meet people's demand for green and pollution-free organic food
