Problems solved by technology

It is an important tree species for landscaping. Nowadays, when raising seedlings of Ligustrum large-leaf, seeds are often used for seedling cultivation, but the survival rate of seeds is often only about 60%. Moreover, the cycle of Ligustrum large-leaf seeds from seedling cultivation to emergence is 25- 30 days, the seedling cycle is longer, resulting in increased seedling cost

Embodiment 1

[0019] A method for raising seedlings of Ligustrum large-leaf high survival rate, comprising the following steps:

[0020] (1) Choose healthy and mature Ligustrum edulis seeds, soak the privet privet seeds with 1% acetic acid solution for 5 minutes, and put the privet privet seeds soaked in the acetic acid solution at 1-3°C Insulate for 15 minutes, then heat up to 22-25°C;

[0021] (2) Soak the privet privet seeds treated in step (1) with a solution prepared by n-butanol, ethanol, and water at a weight ratio of 1:5:200 for 10-15 seconds, take out the seeds after soaking, and air-dry them naturally Until the seed skin is free of moisture, then draw a dent on the epidermis of the privet privet seed, the depth of the dent is 1 / 3-3 / 4 of the thickness of the seed skin, soak the privet privet seed with a treatment agent for 25-30min, The treatment agent is made of the following raw materials by weight: 15 parts of gentian, 8 parts of perilla, 4.5 parts of catechu, 6.8 parts of bark...

Embodiment 2

[0025] On the basis of Example 1, the seedling substrate is made of the following raw materials by weight: 300 parts of peat soil, 65 parts of diatom mud, 35 parts of pine sawdust, 5 parts of licorice, 46 parts of soybean paste, 0.8 part of zinc sulfate , 0.35 parts of magnesium sulfate, 10 parts of urea, 5 parts of potassium dihydrogen phosphate, 4.8 parts of calcium dihydrogen phosphate, 0.12 parts of ammonium molybdate, 0.36 parts of ferrous sulfate, 0.08 parts of copper sulfate, 0.007 parts of vitamin A, 0.006 parts of vitamin K , 0.1 part of compound amino acid, 0.05 part of selenium fertilizer, and 2 parts of tobacco leaves. Before use, use a solution of leek juice and water at a weight ratio of 1:60 to adjust the water content to 18-22%.

Abstract

The invention relates to a high-survival-rate seedling culturing method for ligustrum lucidum. The high-survival-rate seedling culturing method includes the following steps that (1) seeds are selected and pretreated; (2) the ligustrum-lucidum seeds treated in the step (1) are soaked for 10 s to 15 s with a solution prepared in the weight ratio of normal butanol to ethyl alcohol to water of 1:5:200, seeds after being soaked are taken out and subjected to natural air drying till the surfaces of the seeds are free of moisture, then dents are marked on the surfaces of the seeds of the ligustrum lucidum, and the seeds of the ligustrum lucidum are soaked with a treating agent; (3) the seed scratches treated in the step (2) are smeared with a mixture prepared in the weight ratio of herba schizonepetae juice to dextrin of 1:1; (4) the seeds treated in the step (3) are put into seedling culturing substrates and subjected to seedling culturing, and when the seedlings are cultured, the seeds with one sides marked with the dents are placed downwards. The survival rate of the seeds of the ligustrum lucidum prepared with the method is evenly 93.4%, the seedling emergency cycle is 15 days to 18 days, and the economic value of seedling culturing of the ligustrum lucidum is greatly improved.

Description

technical field [0001] The invention belongs to the field of privet privet planting, and in particular relates to a method for raising seedlings of privet privet with high survival rate. Background technique [0002] Large leaf privet, strong adaptability, light-loving, slightly shade-tolerant. It likes a warm and humid climate, a little cold-tolerant, not resistant to drought and barrenness, and is suitable for growing in fertile, deep, moist slightly acidic to slightly alkaline soil. The root system is well developed. Both tillering and germination are strong, resistant to pruning. Resistant to chlorine, sulfur dioxide and hydrogen fluoride. It is an important tree species for landscaping. Nowadays, when raising seedlings of Ligustrum large-leaf, seeds are often used for seedling cultivation, but the survival rate of seeds is often only about 60%. Moreover, the cycle of Ligustrum large-leaf seeds from seedling cultivation to emergence is 25- 30 days, the seedling culti...
