Embodiment 1

[0031] A kind of forsythia intensive dense planting seedling raising method, comprises the following steps:

[0032] S1. Harvest forsythia fruit after it matures in mid-September every year, expose the fruit to the sun, and save the seeds when the fruit shell cracks to remove impurities; collect the seeds and pass through a 16-mesh sieve to remove impurities. Pack the seeds in plastic bags and store them indoors.

[0033] S2. In April of the second year, when the temperature is 15-20°C, sow seeds at an appropriate time. Before sowing, put the seeds in warm water at 30-35°C and keep stirring. After the water temperature drops to room temperature, soak the seeds for 24 hours, and then use ER- CN biological agent diluted 100 times for seed dressing;

[0034] S3. Forsythia nursery plots Select plots that have not been planted with forsythia within 3 years, select plots with flat ground, sufficient light, leeward, sandy loam and good irrigation conditions for seedling cultivation,...

Embodiment 2

[0046] A method for intensively planting seedlings of forsythia, comprising the following steps:

[0047] S1. In mid-September every year, the forsythia fruit is harvested after it matures, exposed to the sun, and the seeds are left when the fruit shell cracks to remove impurities;

[0048] S2. In April of the next spring, when the temperature is 15-20°C, sow at an appropriate time. Before sowing, put the seeds into warm water at 40°C and stir continuously. After the water temperature drops to room temperature, soak the seeds for 12 hours, and then use ER-CN Seed dressing with 100 times diluted biological agent;

[0049] S3. Forsythia nursery plots Select plots that have not been planted with forsythia within 3 years, select plots with flat ground, sufficient light, leeward, sandy loam and good irrigation conditions for seedling cultivation, and perform deep plowing before sowing. The depth is 20 cm.

[0050] S4. Combining with site preparation and furrowing, every 667 m 2 ...

Embodiment 3

[0062] A kind of forsythia intensive dense planting seedling raising method, comprises the following steps:

[0063] S1. In mid-September every year, the forsythia fruit is harvested after it matures, exposed to the sun, and the seeds are left when the fruit shell cracks to remove impurities;

[0064] S2. In April of the next spring, when the temperature is 15-20°C, sow at an appropriate time. Before sowing, put the seeds in warm water at 30°C and stir continuously. After the water temperature drops to room temperature, soak the seeds for 36 hours, and then use ER-CN after taking them out. Seed dressing with 100 times diluted biological agent;

[0065] S3, forsythia nursery plots select plots that have not been planted with forsythia within 3 years, select plots with flat ground, sufficient light, leeward, sandy loam and good irrigation conditions for seedling cultivation, and perform deep plowing before sowing;

[0066] S4. Combining with site preparation and furrowing, ever...

Abstract

The invention discloses an intensive close planting seedling raising method for forsythia suspensa. The method comprises the following steps: seeds are dried in the sun, impurities are removed, and the seeds are soaked in warm water and mixed with a biological agent; fertilization, soil preparation and high ridge making are conducted, and a walkway is reserved between two ridges; ditching is performed before sowing, and ditches are watered thoroughly; the forsythia suspensa seeds are uniformly scattered in the ditches, and a small arched shed is built on the ridges; before and after the forsythia suspensa seedlings emerge, holes are punched in the small arched shed according to conditions to release air, and the small arched shed is removed when the seedlings emerge neatly; weeding is conducted in the seedling stage, watering is conducted according to weather conditions till September to October in the same year, the seedlings grow to 45-60 cm in plant height and 0.3-0.7 cm in stem thickness, and 100 thousand commercial seedlings or more are produced per 667 m<2>. The method adopts an intensive management method, and is fast in seedling emergence and high in emergence rate.

Description

technical field [0001] The invention belongs to the technical field of forsythia planting, and in particular relates to a method for intensively planting and raising seedlings of forsythia. Background technique [0002] Forsythia is one of the commonly used Chinese herbal medicines. It has the functions of clearing away heat and detoxification, dispelling stagnation and reducing swelling. As wild resources become less and less, the market demand is also increasing, and artificial cultivation of Forsythia is gradually rising. Forsythia can be planted all year round, and has strong environmental adaptability. It can be planted in wasteland and plains. It is a crop with high economic value. But the seedling raising method of forsythia is still in its infancy, and the output is far from meeting the market demand, and large-scale seedling raising cannot be realized. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art, and proposes a me...
