Problems solved by technology

[0003] Most of the horned melons are raised by conventional seedlings. The long propagation time, irregular emergence, underdeveloped root system, and slow growth after transplanting and afforestation are all problems faced by conventional seedlings, which limit the high-quality, high-efficiency, and large-scale rapid development of the horned melon.

Embodiment 1

[0025] In mid-July, 2016, select naturally mature, plump, and mildew-free ox horn melon seeds harvested that year, immerse the seeds in lime water with a mass concentration of 1% for 30 minutes to prevent and control seed-borne diseases, and then rinse the seeds repeatedly with clean water. Then soak the washed seeds in warm water at 30°C for 12 hours to make them fully imbibed, and finally wrap them in a high-temperature sterilized wet towel for germination.

[0026] Topsoil, peat soil, coconut peat, and perlite are selected as the matrix raw materials. In order to disinfect more thoroughly and avoid contamination of the matrix, the matrix raw materials are exposed to the sun for 3 days before preparation, and then press the surface soil, peat soil, and coconut peat. , The volume ratio of perlite is measured in the ratio of 2:1:1:0.5, and it is fully mixed after adding the slow and controlled release fertilizer with a mass percentage of 3% at the same time, wherein N:P:K=8 in ...

Embodiment 2

[0030] In the first ten days of April 2017, select naturally mature, plump, and mildew-free seeds of the horn melon harvested in the previous year, and immerse the seeds in lime water with a mass concentration of 1% for 30 minutes to prevent and control seed-borne diseases; Rinse the seeds, then soak the washed seeds in warm water at 32°C for 12 hours to make them fully imbibed, and finally wrap them in a high-temperature sterilized wet towel for germination.

[0031] Topsoil, peat soil, coconut peat, and perlite are selected as the matrix raw materials. In order to disinfect more thoroughly and avoid the infection of bacteria in the matrix, the matrix raw materials are first exposed to sunlight for 4 days before preparation, and then press the topsoil, peat soil, and coconut peat. , the volume ratio of perlite is measured in the ratio of 2:1:1:0.5, and the slow and controlled release fertilizer that is 4% is added by mass percentage is fully mixed at the same time, wherein N:P...

Embodiment 3

[0035] In mid-July, 2017, select the naturally mature, plump, and mildew-free seeds of the horn melon harvested in the previous year, and immerse the seeds in lime water with a mass concentration of 1% for 30 minutes to prevent and control seed-borne diseases; Rinse the seeds, then soak the washed seeds in warm water at 35°C for 12 hours to make them fully imbibed, and finally wrap them in a high-temperature sterilized wet towel for germination.

[0036] Topsoil, peat soil, coconut peat, and perlite are selected as the matrix raw materials. In order to disinfect more thoroughly and avoid the infection of bacteria in the matrix, the matrix raw materials are first exposed to sunlight for 4 days before preparation, and then press the topsoil, peat soil, and coconut peat. , The volume ratio of perlite is measured in the ratio of 2:1:1:0.5, and the slow and controlled release fertilizer is added at 5% by mass percentage and fully mixed, wherein N:P:K=8 in the slow and controlled relea...

Abstract

The invention discloses a method of calotropis gigantea L. mycorrhization container seedling breeding. The method comprises the following processes: treating seeds, preparing a substrate, carrying outmatrix inoculation, sowing the seeds, carrying out management in a seedling stage and taking seedlings out of a nursery. Qualified seeds are selected for disinfection treatment; then carrying out germination acceleration; after white is exposed on the seeds, the seeds are sowed into the pre-prepared matrix inoculated with a strain; and high-quality calotropis gigantea L. container seedlings are obtained through management and nursing in the seedling stage. According to the method provided by the invention, in order to solve the characteristics of slow growth, less developed root system, and easy infection of root rot and stem rot of the calotropis gigantea L. in a young seedling stage, the effects of root enrichment, growth promotion, seedling strengthening, and disease prevention of mycorrhiza are fully utilized, the quality of the calotropis gigantea L. seedlings is improved, the resistance of the seedlings is enhanced, the survival rate of the seedlings is improved and reaches 90%or above, the mycorrhiza has the capacity of self-fertilization, and the supplement of external fertilizers can be reduced in the seedling stage, so that the seedling breeding cost is reduced.

Description

technical field [0001] The invention relates to a method for raising plant seedlings, in particular to a method for raising seedlings in mycorrhizal containers. Background technique [0002] Croissant melon ( Calotropis gigantea L.) is an upright shrub belonging to the family Ascariaceae, which is an upright shrub. It is a positive plant, drought-resistant, and saline-alkali-resistant. Under the can grow well, can play a role in preventing soil erosion or windbreak and sand fixation. The whole plant of oxhorn melon has high commodity development value. Foreign scholars have isolated and identified more than 20 kinds of cardiac glycosides with strong anti-tumor activity, as well as C21 steroids, triterpenes, flavonoids and other components by using oxhorn melon and white flower oxhorn melon; Its comprehensive cellulose is also considered to be the wild fiber with better quality found at present; the white milk extracted from the stems and leaves of the horned melon has a h...
