A kind of cultivation method of pitaya low temperature environment

Abstract

The invention provides a pitaya planting method in a low-temperature environment, and belongs to the technical field of pitaya planting. The method is as follows: (1) Divide the greenhouse into several compartments, use plastic foam or straw mats on the outer surface of the greenhouse, spread heat insulation on the ground inside the greenhouse, install incandescent lamps and heating pipes for heating, and set temperature control in the compartments. The heating device is equipped with several ventilators at the same time; (2) the dragon fruit seedlings are planted in the soil fertilizer bag, and rice bran is evenly sprinkled on the surface of the soil fertilizer bag; (3) a shower is installed directly above the soil fertilizer bag, The shower is connected to the automatic water pump to form an automatic sprinkler system; (4) Daily management. The invention uses automatic temperature control, ventilation, heat preservation and heat insulation to keep the dragon fruit at the optimum growth temperature; uses an automatic spray system to sprinkle water, spray medicine and topdress the dragon fruit, which improves the planting efficiency of the dragon fruit and saves labor costs. At the same time, the soil fertilizer bag is used for planting, which not only drains water but also concentrates the fertilizer effect, which greatly improves the planting efficiency of dragon fruit.

Description

【Technical field】 [0001] The invention relates to the technical field of dragon fruit planting, in particular to a method for planting dragon fruit in a low-temperature environment. 【Background technique】 [0002] Dragon fruit is tropical, subtropical fruit, and its cultivation technology is simple. It likes warmth and humidity, and is shade-tolerant and barren-tolerant. The optimum temperature for growth is 25-35°C, but it can be planted in the open air where the annual minimum temperature is higher than 5°C. The soil requirements are not strict. It can be cultivated on flat land, paddy field, hillside or dry land. It grows well in fertile and well-drained neutral or slightly acidic sandy red soil or loam. It has aerial roots, strong roots, and great vitality. Propagation methods mainly adopt cuttings and grafting. When planting, the row spacing is generally 6-7m, the plant spacing is 3-4m, and 24-38 holes are set per mu, with 3-4 plants per hole. Appropriately apply some...

Problems solved by technology

The current solution is: heat preservation measures mainly adopt the method of double-layer film and straw curtains. This method has problems such as large fog, no ventilation, poor light, etc., and it is easy for plants to get plant diseases.

Publication number CN101715682B "Planting method of dragon fruit in low-temperature environment" shows that heating with electric heating wire in the greenhouse, and covering the heating wire with chaff, etc., will easily cause excessive heat generation. In the case of sufficient oxygen, the burning of chaff and other substances will cause danger. , and there are both electric heating wires and high-wattage electric lamps in the greenhouse, which can easily cause the dragon fruit seedlings or trees to lose their activity and cause death. Therefore, using automatic control methods to complete temperature control has become a low temperature environment for planting dragon fruit key
