Embodiment 1

[0013] Embodiment 1 adopts conventional technology cutting seedling raising method as contrast, and concrete steps are as follows:

[0014] (1) Greenhouses and nurseries

[0015] Set up two nursery greenhouses, build seedbeds with length, width and height (16m×1.2m×0.45m), fill the seedbeds with half and half of the thickness and fine sand, and fill the height of 0.3m. Disinfect with 0.3% potassium permanganate solution. Leave drainage ditches around the cutting bed to avoid water accumulation in rainy season. 3 days before the cutting, the cutting soil was fully sprayed with 0.3% potassium permanganate solution again for disinfection and leveled. Flat 0.67hm 2 Sunny, convenient drainage and irrigation, and flat plots are used as nursery sites.

[0016] (2) Spikes and processing methods

[0017] The cuttings of regional improved varieties of olives from the cutting test site were selected. Collect healthy 1-2a branches growing around the canopy of adult trees with good p...

Embodiment 2

[0025] Embodiment 2 uses the embodiment of the method of the present invention.

[0026] Except that the following methods are different, the rest of the methods are the same as in Example 1 and will not be repeated here.

[0027] First use a rake to clean the uncorrupted leaves and branches in the forest humus, and then sieve it with a coarse sieve; spray 1000 times of Lesben liquid on the sifted forest humus, and let it stand for 2 days. Then mix 80% forest humus + 20% yellow sandy loam, spray carbendazim 800 times solution, the dosage is 10kg / ㎡, cover with plastic film for 24 hours and put it into the seedbed, then cutting can be carried out. The cutting depth of the cuttings is 5-8cm; the humidity of the seedbed is controlled at 75%-85%, and the soil moisture is measured by mass fraction; the temperature of the greenhouse is controlled at 25°C-28°C; the cuttings are treated with 200ppm of No. 1 ABT rooting powder and soaked for 4h.

[0028] Embodiment 1 (contrast) adopts ...

Abstract

The invention discloses a preparation method for a cutting substrate of olea europaea, belonging to the technical field of seedling raising of plant seeds. The method comprises the following steps: cleaning objects like undecomposed leaves and branches in forest humus soil with a rake, and carrying out sieving with a coarse sieve; and spraying Lorsban diluted by 1000 times into the sieved forest humus soil, carrying out standing for 2 days, then uniformly blending 80% of the forest humus soil and 20% of yellow sandy loam, spraying carbendazim diluted by 800 times and with a usage amount of 10kg / m<2>, covering an obtained mixture with a plastic film for 24 hours, and placing the mixture into a seedling bed so as to be able to perform cutting. According to the invention, the cutting depth of cuttings is 5 to 6 cm; the humidity of the seedling bed is controlled in a range of 75% to 80% in terms of percentages by mass; the temperature of a greenhouse is controlled in a range of 22 DEG C to 25 DEG C; and the cuttings are treated by soaking with rooting powder ABT No. 1 with a concentration of 200 ppm for 4 h. By adoption of the substrate prepared by using the preparation method provided by the invention, the survival rate and rooting rate of seedlings are effectively improved; the incidence rate of a seedling period is reduced; the seedling emergence rate and the transplanting survival rate are improved; the cutting substrate provided by the invention reaches a rooting rate increased by 17% to 25% and a survival rate of transplanting improved by 10% to 23% compared with a control cutting substrate; and cultivation of improved Olea europaea seedlings is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of plant cutting and seedling cultivation, and in particular relates to a preparation method of an olive cutting substrate. Background technique [0002] Olive (Olea europaea), also known as olean fruit and Alebu, belongs to Oleaceae (Oleaceae), Olea genus (Olea), native to Asia Minor, is a famous woody oil tree species in the world, with a cultivation history of more than 6,000 years. (Li Juframe, my country's olive industry development overview and prospect[J]. Grain, Oil and Food Science and Technology, 2006, 14(4): 8-10.) The oil squeezed from the olive fruit is called olive oil, which is extremely nutritious and has antioxidant properties. It is strong and has comprehensive health care functions. It has the reputation of "Queen of Vegetable Oil" and "Liquid Gold". Olive fresh fruit processing canned and candied fruit, flavonoids and picrosides that can be extracted from olive leaves, used in the process...
