Embodiment 1

[0022] The method for the dwarfing pumpkin seedling of the present embodiment, comprises the steps:

[0023] (1) Take the pumpkin rootstock, soak it in water at 50°C for 40 minutes, remove it, soak it in water at room temperature at 20°C for 6 hours, then wash off the mucus produced by the seed coat, wash it with water at room temperature, take it out, and use 70% thiophanate-methyl to remove it. Sterilize with 500 times of wet powder for 40 minutes, take it out, wash it with room temperature water, dry the surface of the seed coat, cover it with a plastic film and put it in a germination box for germination. The temperature is controlled at 26°C. When the seeds are white and the radicle grows to When 1.5cm, take out seed from the germination box, obtain the good pumpkin rootstock seed of germination;

[0024] (2) the good pumpkin rootstock seed that the germination that step (1) obtains is packed with mesh bag, is immersed in the aqueous solution of the paclobutrazol wettable...

Embodiment 2

[0028] The method for the dwarfing pumpkin seedling of the present embodiment, comprises the steps:

[0029] (1) Take the pumpkin rootstock, soak it in water at 52°C for 35 minutes, remove it, soak it in water at room temperature at 25°C for 7 hours, then wash off the mucus produced by the seed coat, wash it with water at room temperature, take it out, and use 70% thiophanate-methyl to remove it. Wet powder 600 times liquid disinfection for 35min, remove it and clean it with room temperature water, dry the surface of the seed coat, cover it with plastic film and put it into the germination box for germination, the temperature is controlled at 27°C, when the seeds are white and the radicle grows to When 2cm, take out seed from the germination box, obtain the good pumpkin rootstock seed of germination;

[0030] (2) the good pumpkin rootstock seed that the germination that step (1) obtains is packed with net bag, is immersed in the aqueous solution of the paclobutrazol wettable p...

Embodiment 3

[0034] The method for the dwarfing pumpkin seedling of the present embodiment, comprises the steps:

[0035] (1) Take the pumpkin rootstock, soak it in water at 55°C for 30 minutes, remove it, soak it in water at room temperature at 30°C for 8 hours, then wash off the mucus produced by the seed coat, wash it with water at room temperature, take it out, and use 70% thiophanate-methyl to remove it. Wet powder 800 times liquid disinfection for 30 minutes, remove it and clean it with room temperature water, dry the surface of the seed coat, cover it with a plastic film and put it in a germination box for germination. The temperature is controlled at 28°C. When the seeds are white and the radicle grows to When 2.5cm, take out seed from accelerating germination case, obtain the good pumpkin rootstock seed of accelerating germination;

[0036] (2) the good pumpkin rootstock seed that the germination that step (1) is obtained is packed with mesh bag, is immersed in the aqueous solutio...

Abstract

The invention discloses a method for dwarfing pumpkin seedlings, and belongs to the technical field of plant cultivation. The method includes the steps: (1) taking pumpkin rootstocks, soaking the taken pumpkin rootstocks, fishing out the soaked pumpkin rootstocks, soaking the fished out pumpkin rootstocks, rubbing off mucilage of the rootstocks, cleaning the rootstocks by the aid of room-temperature water, taking out the cleaned rootstocks, performing disinfection on the rootstocks by the aid of 500-800-time solution of 70% of thiophanate methyl wettable powder, fishing out the disinfected rootstocks, cleaning the rootstocks by the aid of room-temperature water, wiping seed coat surfaces, and accelerating germination; (2) soaking the rootstocks into water solution of paclobutrazol wettable powder, taking out the soaked rootstocks, and draining moisture; (3) sowing in a seedling-raising disk, and covering the seedling-raising disk with a plastic film until pumpkin rootstock seedlings with regular germination is acquired; (4) grafting scions onto the pumpkin rootstock seedlings when cotyledons of the pumpkin rootstock seedlings grow one leaf and one core. According to the method, germinant pumpkin seeds are soaked by the aid of the water solution of the paclobutrazol wettable powder to restrain growth of the pumpkin seedlings, dwarfing function is achieved, the method solves the problems that hypocotyls of the pumpkin seedlings are elongated, easily lodged and cannot stand upright, and quality of grafted seedlings is improved.

Description

technical field [0001] The invention relates to a method for dwarfing pumpkin seedlings, belonging to the technical field of plant cultivation. Background technique [0002] Pumpkins are widely used as rootstocks for grafting melons such as watermelons, bitter gourds, and cucumbers. Generally, white-seeded pumpkins are commonly used, and they are divided into multi-purpose types and single types. Among them, the multi-purpose rootstock can be used for grafting rootstocks such as watermelon, bitter gourd and cucumber, and the single-type rootstock is generally only suitable for one kind of melon grafting, such as special rootstocks for cucumber grafting, watermelon grafting and balsam pear grafting. The above two types of pumpkin rootstocks have the characteristics of strong germination potential, well-developed root system, strong disease resistance and regeneration ability, vigorous plant growth, strong cold resistance, heat resistance and stress resistance, strong grafting...
