Problems solved by technology

Dragon fruit is heat and drought resistant, light-loving and shade-loving, fertile and barren-loving. Its growth temperature is 11°C to 38°C, the most suitable growth temperature is 25°C to 35°C, and it can withstand low temperatures of 0°C and high temperatures of 40°C. Low temperature will cause freezing damage to plants, while high temperature will inhibit its growth

Embodiment Construction

[0017] A kind of method for raising seedlings of dragon fruit cuttings fast rooting, comprises the following steps:

[0018] (1) The seedling bed should choose a field that is ventilated to the sun, fertile in soil, and convenient for drainage and irrigation. Make a furrow with a furrow of 90 cm, and put a 15 cm thick substrate 10 cm below the furrow surface. The substrate is sand, soil, A mixture of organic fertilizer, perlite and decomposed bagasse, adjust the pH value of the substrate to 6.5, if it is lower than 6.5, use plant ash to improve;

[0019] (2) Select pure, robust growth, no pests and diseases, annual fully mature dragon fruit branches as cuttings, cut the base of the cuttings into a wedge shape and expose the xylem, the length is 1cm, and insert 0.2% high manganese after drying in the sun for 24 hours Soak in potassium acid disinfectant solution for 30 minutes, remove and dry in the air;

[0020] (3) Cutting time is selected in March. When cutting, insert the c...

Abstract

The invention discloses a seedling breeding method rapid rooting of hylocereus undatus cutting. Treatment on hylocereus undatus cutting seedlings and soaking treatment by using a potassium permanganate solution exert an effect of sterilization; root rot is eradicated and hylocereus undatus rooting is promoted; the seedling breeding medium consists of sand, soil, organic fertilizer, perlite and decomposed sugarcane, can provide enough organic matters, has loose soil, does not harden easily, can provide nutrients in a seedling period, and promotes the growth of seedling roots; in the seedling period, large amount of water for watering is needed, and a phenomenon of root rot which is caused by water ponding formed by the water does not occur easily; reasonable fertilizer application is performed according to different fertilizer needed in the growing period of the cutting seedlings; the adopted water and fertilizer have rich nutrients, have slow and lasting fertilizer effects, do not harm the roots, are beneficial for the growth of the cutting seedlings, shorten the time for seedling breeding, and enable high survival rate. The seedling breeding method provided by the invention is simple, has low costs, and can greatly increase the speed of seedling breeding; the breeding speed is fast; spindling of the seedlings does not occur easily; the disease and pet resistance is good; the fruit setting rate is high; and the method has high economic benefits and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a seedling raising method for rapid rooting of dragon fruit cuttings. Background technique [0002] Pitaya is native to the desertified regions of Central and South America and is a typical subtropical and tropical plant. It is a plant of the genus Cactaceae. It is named for its soft scales that look like dragons on the surface of its flesh. It is also known as Yulong fruit, dragon pearl fruit, and fairy honey fruit. Dragon fruit is heat and drought resistant, light-loving and shade-loving, fertile and barren-loving. Its growth temperature is 11°C to 38°C, the most suitable growth temperature is 25°C to 35°C, and it can withstand low temperatures of 0°C and high temperatures of 40°C. Low temperature will cause freezing damage to plants, while high temperature will inhibit its growth. The cultivation and growth of dragon fruit do not have strict requirements on the...
