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 cutting grafting method for reducing rootstock germination and tiller regeneration, which comprises the steps of rootstock seedling raising, scion seedling raising, grafting and management, and belongs to the field of crop planting. The invention can effectively inhibit the regeneration of rootstock sprouts, reduce the number and time of manual removal of sprouts after grafting, reduce labor input, and at the same time improve the grafting survival rate of watermelons, reduce nutrient competition, promote the growth of scions, and improve grafted seedlings. Quality has laid the foundation for obtaining high-yield and high-quality watermelons.

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...
