Problems solved by technology

[0003] The cultivation of dragon fruit has high requirements on temperature, and absolute temperature needs to be guaranteed. Because the temperature in tropical regions is high all year round, the fruiting period of dragon fruit lasts for a long time. The latitude continues to increase, but the average annual temperature is gradually decreasing. At this time, the flowering and fruiting period of dragon fruit will be shortened. Under normal circumstances, the normal daily average temperature of dragon fruit flowering and fruiting period is higher than 21°C. It will prolong the time for fruit development and maturity. Dragon fruit usually takes 30-45 days from flowering to fruit ripening, and the temperature needs to be maintained at 25-35°C to make the fruit rapidly expand, and it can be picked after 30-35 days. 15-25℃, it will prolong the fruit ripening time to 35-45d, affecting the fruit quality

Embodiment 1

[0025] The invention provides a kind of planting method of dragon fruit low temperature environment, specifically comprises following operation steps:

[0026] Step 1: Soil selection and modification: select neutral or slightly alkaline soil with a pH value between 7.0-7.8, and then add modifiers to the soil;

[0027] Step 2: Establishment of the greenhouse planting system: build the greenhouse skeleton structure, divide the greenhouse into 150m2 planting sections, pre-embed organic fertilizers in each planting section, and finally establish a covering system, automatic heating system and irrigation system inside and outside the greenhouse

[0028] Step 3: field planting: the pitaya plants are planted in various planting intervals by the horizontal bar sagging method, the row spacing is 50cm, the plant spacing is 35cm, and the implantation depth is 3cm. In each planting interval, the root of the pitaya is used as the center of the circle to establish a thermal insulation layer;...

Embodiment 2

[0039] A planting method of pitaya low temperature environment, specifically comprises the following steps:

[0040] Step 1: Soil selection and modification: select neutral or slightly alkaline soil with a pH value between 7.0-7.8, and then add modifiers to the soil;

[0041] Step 2: Establishment of the greenhouse planting system: build the greenhouse skeleton structure, divide the greenhouse into 150m2 planting sections, pre-embed organic fertilizers in each planting section, and finally establish a covering system, automatic heating system and irrigation system inside and outside the greenhouse

Abstract

The invention discloses a method for planting hylocereus undatus in a low-temperature environment, and specifically relates to the technical field of hylocereus undatus planting. The method specifically comprises the following operation steps: step 1, soil selection and modification; step 2, establishment of a greenhouse planting system; step 3, field planting; and step 4, daily planting management. The method for planting hylocereus undatus in a low-temperature environment determined by the invention can promote plant growth and metabolism, and has the advantages of promoting flower bud differentiation, suppressing certain diseases and insect pests, increasing yield, and improving a commercial fruit rate. At the same time, an organic liquid fertilizer is pre-buried in each planting area,and the fermentation of various saprophyte and microorganisms helps to keep the soil temperature warm, and helps to improve thermal insulation of plant plants. At the same time, the greenhouse planting system is established, so that heat preservation and cooling operations can be effectively carried out according to the internal environment of the greenhouse in time to ensure the growth and development of hylocereus undatus plants in the environment of 25-35 DEG C.

Description

technical field [0001] The invention relates to the technical field of pitaya planting, more specifically, the present invention relates to a planting method of pitaya in a low-temperature environment. Background technique [0002] Dragon fruit is also known as red dragon fruit, dragon fruit, fairy honey fruit. It is an oval fruit with a diameter of 10-12cm. The nutritional value of dragon fruit is very high. It contains plant protein, anthocyanins, vitamins, Water-soluble dietary fiber has a great effect on human body function. [0003] The cultivation of dragon fruit has high temperature requirements, and absolute temperature needs to be guaranteed. Because the temperature in tropical areas is high all year round, the fruiting period of dragon fruit lasts for a long time, and the latitude continues to increase, but the average annual temperature is gradually decreasing. At this time, the flowering and fruiting period of dragon fruit will be shortened. Under normal circums...
