Cutting seedling raising method of olive light substrate

Abstract

The invention relates to a cutting seedling raising method for olive light matrix. The cutting seedling raising method for the olive light matrix comprises the steps that an electric-heating slotting machine is arranged in a solar greenhouse, and mixed light matrix composed of 30 % of perlite, 30 % of vermiculite and 40 % of peat soil or 50 % of the perlite and 50 % of the peat soil is selected as the matrix for seedling raising; branches are selected as cuttings, the ages of the branches are over 6 months, the lengths of the branches are over 60 cm, the diameters of the branches are 3 to 8 mm, the lengths of the cuttings are cut to 10 to 15 cm, 4 to 6 knots are reserved of each branch, and two pairs of buds and 4 leaves are reserved at the top end of each branch; the cuttings are cleaned by clear water, the cuttings are divided into different groups according to the thickness of the branches, each 50 branches are bundled into a bundle, the branches are quickly dipped in the indolebutyric acid solutions with the concentrations ranging from 2000 mg / kg to 5000 mg / kg according to the thickness of the branches from slender to thick, and the dipping depths are 5 cm; the planting distances of the cuttings is 5 to 6 cm, the row spacing of the cuttings is 3 to 4 cm, the temperature of the solar greenhouse is 18 to 25 DEG C, the humidity is over 85 %, the temperature, ranging from 20 to 25 DEG C, of slotting machine soil is maintained constantly for the primary 20 days, the temperature of the solar greenhouse is maintained in a certain range, and the water content is 60 to 70 %; the cutting seedling raising method for the olive light matrix has the advantages that the root striking rate of the cutting seedling raising method is over 90 %, roots can be struck after cutting is conducted for 40 to 45 days, lower bed seedlings are interweaved with the light matrix, elastic root rolls are easy to generate, the roots are not damaged during transplanting, the survival rate of transplanting is high, the weight is light, the water-retaining property is good, and long-distance transportation is facilitated.

Description

technical field [0001] The invention belongs to a method for raising seedlings in the field of forestry, and in particular relates to a method for raising seedlings by cutting olive light substrates. Background technique [0002] Olive (Olea europaea L.), also known as olean, belongs to Oleaceae (Oleaceae) Oleaceae (Olea), an evergreen tree, is a world-renowned high-quality woody oil and fruit tree species, and is also the earliest known, domesticated, and used by humans. One of the oil crops grown. my country's introduction of olives began in 1964. Longnan, located in the Qinba Mountains, is one of the best suitable areas for olives in my country. By the end of 2014, the olive planting area in Longnan City reached 23,700 hm 2 , In 2014, the output of fresh fruit was 15,000 tons, and oil extraction was 2,325 tons, realizing an output value of 850 million yuan. Olive has ranked first in the country in terms of planting area, output and processed product types. Olive has be...
