Embodiment 1

[0025] Variety selection: In this example, the gourd rootstock "Jingxinzhen No. 1" was selected as the rootstock for grafting, and the watermelon variety "Zaojia 8424" was used as the scion.

[0026] Disinfection of nursery facilities: nursery sites, sheds, shed films, heat preservation quilts and the utensils and used substrates used in the entire production process are all sprayed with 40% formaldehyde 50 times solution, and the dosage is 30ml / m 2 , closed for 48 hours, and then ventilated for 5 days to start seedling cultivation after the formaldehyde is completely volatilized.

[0027] (1) Rootstock seedling cultivation: sterilize the rootstock seeds, then soak the seeds in warm soup for 8-24 hours, then wash and dry the seeds, accelerate germination at about 30°C, and sow them in plug trays when the radicle grows to 0.5cm. Graft when it grows to 1 leaf and 1 heart.

[0028] (2) Scion seedling raising: sterilize the watermelon scion seeds, then soak the seeds in warm soup...

Abstract

The invention discloses a watermelon top cuttage grafting method reducing regeneration of rootstock sprout tillers, comprising rootstock seedling culture, scion seedling culture, grafting, managementand the like, and belonging to the field of crop planting. The method can effectively inhibit regeneration of rootstock sprout tillers, reduces times and time for manual removal of sprout tillers after grafting, reduces the labor input, and meanwhile, can increase the watermelon grafting survival rate, reduce nutrient competition, promote growth of the scions, and increase the quality of the grafted seedlings, and thus laying foundation for obtaining high-yield high-quality watermelon.

Description

technical field [0001] The invention belongs to the field of crop planting, and relates to a watermelon grafting method, in particular to a watermelon top-cutting grafting method which reduces rootstock germination and regeneration. Background technique [0002] Watermelon is an important horticultural crop in my country, which plays a huge role in increasing farmers' income and meeting people's growing demand for melons and fruits. In recent years, continuous cropping obstacles in watermelon cultivation have become increasingly serious, especially under facility cultivation conditions, and soil-borne diseases such as Fusarium wilt have aggravated, affecting the normal growth of watermelon plants, resulting in reduced yield and quality, and hindered the development of the watermelon industry . Grafting is an effective measure to overcome the above problems, so it has been widely used in watermelon production. [0003] At present, the main methods of watermelon grafting are...
