Problems solved by technology

However, although the germination rate of the existing container seedling cultivation method has been significantly improved compared with the traditional method, there will be blight, root rot and other phenomena during the seedling cultivation process, resulting in a low seedling survival rate

Embodiment 1

[0023] Present embodiment provides a kind of container seedling raising method of Ilex japonica, it comprises the following steps:

[0024] S1, river bed fine sand, garden soil, compound fertilizer are mixed with mass ratio 2:1:1 to make seedling-raising matrix, wherein, compound fertilizer is made up of the component of following mass ratio: decomposed farmyard manure: potassium dihydrogen phosphate=25 :1;

[0025] S2. Fill the seedling raising substrate of S1 into a seedling raising bag of 16cm×14cm, place the above seedling raising bag in a seedling raising pond of 40m×0.7m×0.2m, then pour the seedling raising substrate and the seedling raising bag with water, and let stand for 48 hours;

[0026] S3, choose ripe holly holly seeds with green seed coat, no damage and 1000-grain weight of 40g, soak them in potassium permanganate solution with a mass fraction of 0.3% for 0.75h, wash them with water, place them in warm water at 50°C for 1h, and then Rinse with water, drain and ...

Embodiment 2

[0031] The steps of this embodiment are the same as in Embodiment 1, the difference is:

[0032] In S1, the mass ratio of riverbed fine sand, nursery soil, and compound fertilizer is 2:0.9:0.9, and the mass ratio of each component of compound fertilizer is: decomposed farmyard manure: potassium dihydrogen phosphate=20:1;

[0033] Stand still in S2 for 46h;

[0034] The soaking time of potassium permanganate solution in S3 is 0.5h, soak in warm water at 55°C for 1.1h, then add water to 1.2cm above the seed plane, cover with towel and continue soaking for 10h;

[0035] Sow 3 seeds in each seedling bag in S4, and the sowing depth is 0.5cm;

[0036] In S5, the plastic film was uncovered when the seedlings broke through the soil 1 cm.

Embodiment 3

[0038] The steps of this embodiment are the same as in Embodiment 1, the difference is:

[0039] In S1, the mass ratio of riverbed fine sand, nursery soil, and compound fertilizer is 2:1.1:1.1, and the mass ratio of each component of compound fertilizer is: decomposed farmyard manure: potassium dihydrogen phosphate=30:1;

[0040] Stand still in S2 for 50h;

[0041] Soak in potassium permanganate solution in S3 for 1 hour, soak in warm water at 55°C for 1.2 hours, then add water to 1.3 cm above the seed plane, and cover with a towel to continue soaking for 48 hours;

[0042] 5 seeds were sown in each seedling bag in S4, and the sowing depth was 1 cm;

[0043] In S5, the plastic film was uncovered after the seedlings broke through the soil 1.2 cm.

Abstract

The invention belongs to the technical field of forestry seedling raising, and particularly relates to a container seedling raising method for ammopiptanthus mongolicus, which comprises the following steps that: S1, sandy soil, nursery soil and a compound fertilizer are mixed to prepare a seedling raising matrix according to a mass ratio of 2: (0.9-1.1): (0.9-1.1); S2, a seedling raising bag is filled with the seedling raising matrix, the seedling raising bag is placed in a seedling raising pond, and the seedling raising matrix and the seedling raising bag are thoroughly watered; S3, the seeds are disinfected and washed, the seeds are soaked in water for 1-1.2 h, water is added to submerge the seeds by 1-1.3 cm after washing and draining, the seeds are covered with water absorption cloth, and soaking lasts for 10-15 h; S4, sowing is performed when the temperature of the seedling raising matrix is above 15 DEG C, and the seedling raising bag is covered with a plastic film after sowing; S5, after the seedlings break through the ground by 1-1.5 cm, the plastic film is uncovered, watering is conducted once when the first pair of real leaves grow, weeds are removed at the same time, and then watering is conducted once every 15-20 days; S6, after the fourth pair of real leaves and more than three branches of the seedlings grow, and the height of the seedlings is more than 15 cm, outplanting and transplanting are performed. The container seedling raising method for ammopiptanthus mongolicus can prevent ammopiptanthus mongolicus seedlings from the disease, and meanwhile, the germination rate, the survival rate and the outplanting rate of the seedlings are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of forestry seedling cultivation, and in particular relates to a container seedling cultivation method of holly. Background technique [0002] Sand holly is a second-class national key protected plant in China and the only evergreen broad-leaved tree species in Northwest my country. It is not easy to survive transplantation and afforestation of field seedlings of Ilex japonica, so in the past, direct seeding afforestation was usually used in the rainy season. However, this method is affected by rainfall and rainfall time, and the chance is too large, and the germination rate and survival rate of seedlings are still unstable. The most effective way is to grow seedlings in containers. Compared with other traditional seedling raising methods, this method has the following advantages: the environment is stable, so the germination rate is high, and the seedlings emerge neatly, and the size of the seedlings is eve...
