Stevia two-section floating plate cutting seedling culture method

Abstract

The invention discloses a stevia two-section floating plate cutting seedling culture method. Floating plates are used for stevia cutting seedling culture; one floating plate seedling culture plate water pool is arranged in the tree shade, and the other floating plate seedling culture plate water pool is arranged in the sunshine; firstly, the stem sections of the stevia are cut in the floating seedling culture plate in the tree shade; after the rooting and survival, the stem sections and the floating plate are jointly transferred into a sunshine water pool for culture and seedling strengthening. The seedling culture method has the advantages that the cutting survival rate can be improved; the strengthening seedling can be cultured; meanwhile, the seedling culture management work quantity can be reduced; the work efficiency is improved.

Description

technical field [0001] The invention discloses a two-segment floating plate cutting seedling raising method of stevia, which relates to the technical field of cutting propagation of stevia rebaudiana, and more specifically relates to a stevia two-segment floating plate cutting seedling raising method. Background technique [0002] Stevia is a crop that takes cuttings as the main propagation method. The method of raising seedlings by cuttings in floating trays is to build a pool for floating seedlings in the field, add nutrient solution to the pool, and cut the stems of Stevia in polypropylene. On the culture medium in the foam seedling tray, place the seedling tray on the surface of the nutrient solution to float the seedlings, build a small bow shed above the pool, cover the small bow shed with plastic film and sunshade net, and cover the cover during the day and uncover it at night. This method of raising seedlings does not work well in summer. First of all, the nursery p...

This method of raising seedlings does not work well in summer

First of all, the nursery pool is built under the sun in the field. Although there is shade protection from the cover, due to the low bow shed, the sunlight is strong during the day and the heat radiation is high, it is easy to cause the temperature in the shed to be too high and affect the survival rate.

In addition, in order to take into account the light and shade of the seedbed, the sunshade net must be covered during the day and uncovered at night, which is cumbersome
