Problems solved by technology

However, because the outer testa of Sapindus seeds is hard and waterproof, it is extremely difficult for water to penetrate the outer testa, so the natural germination power is extremely low, and its germination rate is about 8.9%.
Seriously affect the mass reproduction of Sapindus
The best method of raising seedlings in the prior art is to carry out sand storage stratification treatment to Sapindus seeds, although its germination rate can reach 80%, but the time period of seedling raising is as long as 120 days
Therefore, the main shortcoming of prior art still has two: the germination rate is on the low side and the seedling cultivation period is long

Embodiment 1

[0017] (1) Screening of Sapindus seeds: Soak the seeds in warm water to screen out diseased and empty seeds.

[0018] (2) Soak the seeds in cold water at 5°C for 30 minutes.

[0019] (3) Use an electric grinder to grind 0.1-0.2mm along the hilum of the Sapindus seed until the umbilical seam is exposed; grind the seeds intermittently, the continuous grinding time is 1-2 seconds, and put them in 5°C water to cool in the middle .

[0020] (4), soak in warm water at 20°C for 5 days, and change the water once a day during the process.

[0021] (5), place 3-5cm shallow burial in wet soft soil under 20°C-30°C environment, water once a day with fresh water, each time until the soil is drenched, the germination rate is 98% after 10 days.

Embodiment 2

[0023] (1) Screening of Sapindus seeds: Soak the seeds in warm water to screen out diseased and empty seeds.

[0024] (2) Soak the seeds in cold water at 15°C for 30 minutes.

[0025] (3) Use an electric grinder to grind 0.1-0.2mm along the hilum of the Sapindus seed until the umbilical seam is exposed; grind the seeds intermittently, the continuous grinding time is 1-2 seconds, and put them in 8°C water to cool in the middle .

[0026] (4) Soak the seeds in warm water at 30°C for 3 days, and change the water once a day during the process.

[0027] (5), placed in 3-5cm shallow burial in wet and soft soil under 20°C-30°C environment, watered once a day with fresh water, until the soil is soaked each time, the germination rate was 98.5% after 9 days.

Embodiment 3

[0029] (1) Screening of Sapindus seeds: Soak the seeds in warm water to screen out diseased and empty seeds.

[0030] (2) Soak the seeds in cold water at 10°C for 30 minutes.

[0031] (3) Use an electric grinder to grind 0.1-0.2mm along the hilum of Sapindus seeds until the umbilical seam is exposed; intermittently grind the seeds for 1-2 seconds, and put them in 13°C water to cool in the middle .

[0032] (4), Soak the seeds in warm water at 40°C for 4 days, and change the water once a day during the process.

[0033] (5) Place 3-5cm shallow burial in wet and soft soil under 30°C-40°C environment, water once a day with fresh water until the soil is drenched, and the germination rate is 97.5% after 8 days.

[0034] The sapindus of the present invention can be applied to Sapindus delavayi, Sapindus mukurossi gartn, Sapindus tomentosus Kurz, and Sapindus rarak DC. , Shiping Sapindus rarak (Sapindus rarak DC.var.velutinus C.Y.Wu) and other species of Sapindus rarak DC.var.velu...

Abstract

The invention provides a novel method for culturing sapindus seedlings. The novel method comprises the following steps that (1), sapindus seeds are soaked in cold water with the temperature ranging from 5 DEG C to 15 DEG C for half an hour; (2) an electric grinding machine is utilized for grinding the hilum portions of the sapindus seeds by 0.1-0.2mm until the hilum seams are exposed; (3) the sapindus seeds with the exposed hilum seams are soaked in the warm water with the temperature ranging from 20 DEG C to 40 DEG C for three to five days; (4) the seeds are shallowly buried, the seeds soaked in the step three are placed into the wet and soft soil for 3-5cm under the environment with the temperature ranging from 20 DEG C to 40 DEG C and shallowly buried and can sprout in seven to ten days. According to the novel method for culturing the sapindus seedlings, the seedling culturing period is short, the germination rate is high and the cost is low.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a new method for raising seedlings of Sapindus. Background technique [0002] Soapberry is an arbor of the genus Sapindus in the family Sapindaceae, and it is one of the best trees for landscape forests. Its fruit contains a large amount of saponins and can be used as raw materials for making natural detergents, so it has significant economic benefits. Propagation by seed is one of the easiest, cheapest and most effective methods of propagating arbors today. However, because the outer testa of Sapindus seeds is hard and waterproof, it is extremely difficult for water to penetrate the outer testa, so the natural germination power is extremely low, and its germination rate is about 8.9%. Seriously affect the mass reproduction of Sapindus. The best seedling raising method in the prior art is to carry out sand storage stratification treatment to Sapindus sativa seeds, although its ger...
