A kind of method of cuttage propagation of Prunus alba

Abstract

The invention relates to a cutting propagation method for cerasus humilis sok, and belongs to the technical field of agricultural and forestal seedling growing. The cutting propagation method mainly comprises the following steps of: taking subterraneous stems of cerasus humilis sok as cutting shoots, and cutting the subterraneous stems into 10-20 cm stem sections, and preserving in the sand after cutting; before cutting, performing soaking for 5 minutes by use of a potassium permanganate solution with concentration being 1%, and soaking morphological lower ends of the subterraneous stems for 3 seconds in an alpha-naphthylacetic acid solution with concentration being 800 mg / L, and drying in the sun, wherein soaking depth is 1 / 3-1 / 2 the length of the subterraneous stems; after applying a fertilizer through a slotting machine, ploughing under great depth to form flat field intervals, horizontally putting the subterraneous stems on a soil surface, performing earthing, performing watering, adding coverings, and keeping soil wet; removing the coverings when seedlings emerge, applying urea when the seedlings are 18-25 cm high, performing watering after applying the fertilizer, and performing normal management. The cutting propagation method is adopted to propagate cerasus humilis sok, requirements on environment conditions are not strict, special temperature-control humidity-control and light-shielding facilities are not needed, and a seedling rate can be as 98% or higher.

Description

technical field [0001] The invention belongs to the technical field of raising seedlings in agriculture and forestry, and in particular relates to a method for cutting and propagating underground stems of Prunus aurantium. Background technique [0002] Ole ( Cerasus humilis Sok) is a kind of wild fruit tree belonging to the subgenus Dwarf Cherry in Rosaceae. It contains many types of nutrients and high content, which is better than walnut fruits such as cherries, plums, apricots, and peaches. vitamin A, vitamin B 2 , Vitamin B 12 , vitamin C, vitamin E, and trace elements potassium, nitrogen, calcium, phosphorus, iron, manganese, zinc, magnesium, selenium, etc. are rich in content, most of which are several to dozens of times higher than the above-mentioned fruits, and contain lysine 18 kinds of amino acids, the sugar content of mature fruit is as high as 14%-19%. The content of calcium and iron per 100 grams of fresh fruit is 7-10 times and 6-10 times that of apples, r...

Problems solved by technology

Cutting propagation is an effective way to speed up the breeding rate of fine varieties of Prunus aurantium and reduce costs. At present, the cutting propagation of Prunus auricula is mainly the seedling cultivation of twig cuttings. Strong growth and other characteristics, but strict requirements on cutting conditions, especially on environmental temperature, humidity, and light, requiring special temperature control, humidity control, and shading facilities. If the temperature, humidity, and light are not well controlled, the survival rate of cuttings very low

In addition to twig cutting seedlings, burying root seedlings is also a common method of cutting propagation of Plum. After the leaves fall and before germination, dig the roots, store them in the sand, and bury the roots when the conditions are suitable. This method is simple and easy, but the emergence of The rate is difficult to control, the highest maintained at 70-85%
