Embodiment 1

[0018] The seedling raising method of Luo Han Guo comprises the following steps:

[0019] 1) Cut the grosvenor fruit cuttings with a length of 0.7 meters and keep 5 bud eyes, and then use ultraviolet light to sterilize the grosvenor fruit cuttings. The intensity of the ultraviolet light is 120μW / cm 2 , the disinfection time is 20 minutes;

[0020] 2) Put the seedling bag filled with nutrient soil on the seedbed. The nutrient soil outside the nutrient soil is made by mixing sandy loam, decomposed chicken manure and superphosphate according to the weight ratio of 60:40:0.2, and the nutrient soil is drip-irrigated and moistened. , the watering time is 2 hours. After the watering is completed, insert the Luo Han Guo cuttings in the nutrient soil, and the bud eyes of the Luo Han Guo cuttings are exposed;

[0021] 3) Use drip irrigation to water the nutrient soil in the seedling bag once every 3 days, so that the nutrient soil in the seedling bag maintains a humidity of 30%. Plant...

Embodiment 2

[0024] The seedling raising method of Luo Han Guo comprises the following steps:

[0025] 1) Cut the grosvenor fruit cuttings with a length of 0.5 meters and keep 6 bud eyes, and then use ultraviolet light to sterilize the grosvenor fruit cuttings. The intensity of the ultraviolet light is 90μW / cm 2 , the disinfection time is 30 minutes;

[0026] 2) Put the seedling bag filled with nutrient soil on the seedbed. The nutrient soil outside the nutrient soil is made by mixing sandy loam, decomposed chicken manure and superphosphate according to the weight ratio of 55:45:0.1, and the nutrient soil is drip-irrigated and moistened. , the watering time is 3 hours. After the watering is completed, insert the Luo Han Guo cuttings in the nutrient soil, and the bud eyes of the Luo Han Guo cuttings are exposed;

[0027] 3) Use drip irrigation to water the nutrient soil in the nursery stock bag once every 2 days, so that the nutrient soil in the seedling stock bag maintains a humidity of 3...

Embodiment 3

[0030] The seedling raising method of Luo Han Guo comprises the following steps:

[0031] 1) Cut the grosvenor fruit cuttings with a length of 0.8 meters and keep 3 bud eyes, and then sterilize the grosvenor fruit cuttings with an ultraviolet lamp. The intensity of the ultraviolet lamp is 180μW / cm 2 , the disinfection time is 10 minutes;

[0032] 2) Put the seedling bag filled with nutrient soil on the seedbed. The nutrient soil outside the nutrient soil is made by mixing sandy loam, decomposed chicken manure and superphosphate according to the weight ratio of 65:35:0.3, and the nutrient soil is drip-irrigated and moistened. , the watering time is 3 hours. After the watering is completed, insert the Luo Han Guo cuttings in the nutrient soil, and the bud eyes of the Luo Han Guo cuttings are exposed;

[0033] 3) Use drip irrigation to water the nutrient soil in the seedling bag once every 4 days, so that the nutrient soil in the seedling bag maintains a humidity of 25%. Plant ...

Abstract

The invention discloses a siraitia grosvenori seedling method and belongs to the technical field of seedling. The siraitia grosvenori seedling method includes the steps of 1), subjecting siraitia grosvenori cuttings to disinfection with ultraviolet rays; 2), inserting the cuttings in moist nutrient soil to have bud eyes exposed; 3), performing drop irrigation every 2-4 days, transplanting new buds to planting grooves after growing for 3-6 days and watering the new buds every 5-8 days; 4), setting a frame for the siraitia grosvenori after the cuttings grow to 1.2-1.5 meters, fixedly mounting seedling bags on the frame and reserving 3-6 holes, dipping rooting powder on the cuttings at the height corresponding to the seedling bags, allowing the cuttings to penetrate the seedling bags, filling the nutrient soil in the seedling bags, and spraying water on the nutrient soil in the seedling bags every 1-3 days till the new buds grow from the holes. With the method, problems that the survival rate of seedling propagation of the siraitia grosvenori is low resulting in the fact that seedling diseases and inset pests are serious and the yield of the siraitia grosvenori is low and the like can be effectively solved.

Description

technical field [0001] The invention relates to a method for raising seedlings, which is a method for raising seedlings of Luo Han Guo. Background technique [0002] Luo Han Guo (scientific name: siraitia grosvenorii), commonly known as "fairy fruit", is a perennial vine of Cucurbitaceae. Its leaves are heart-shaped, dioecious, flowering in summer and fruiting in autumn. Traditional Chinese medicine uses its fruit as medicine, which contains mogroside, various amino acids and vitamins and other medicinal ingredients. Luo Han Guo has very special requirements on the growing environment, and it can only grow in the north of Guangxi, China. It is one of the famous specialty products of Guilin, Guangxi, "Guilin Three Treasures". Yongfu County, Rong'an County, and Lingui County in Guangxi are the three major producing areas of Luo Han Guo, accounting for 90% of the world's output, of which Yongfu County is the origin. At present, the global average annual output of Luo Han Guo...
