Problems solved by technology

Wherein leaning on the grafting method retains the root system of scion earlier when grafting, and it is excised after surviving, and management is convenient, and survival rate is higher, but operation is loaded down with trivial details, cuts off the hypocotyl of stock and scion easily during operation, and work efficiency is lower; And , the position of the incision is low, and it is prone to soil pollution and adventitious roots after planting, which reduces the effect of grafting and disease prevention; in addition, the grafting method is only suitable for rootstock species with thinner hypocotyls, which restricts the popularization and application of this grafting method

Embodiment 1

[0030] (1) Variety selection: In this example, 'Zaojia (84-24)' watermelon was selected as the scion, and 'Jiuzhen No. 1' pumpkin was used as the rootstock.

[0031] (2) Preparation of seedling-raising substrate: take peat and vermiculite in a ratio of 2:1 by volume, add 2 kg of nitrogen, phosphorus and potassium ternary compound fertilizer per cubic meter of substrate, mix well as seedling-raising substrate, and pack in 10cm×10cm plastic bowls middle.

[0032] (3) Seed germination and sowing: select full scion watermelon seeds, first use a volume fraction of 1% formalin solution to disinfect for 1 hour, then rinse with clear water for 3 to 4 times, and then place them in clear water to soak the seeds for 6 hours. Germinate in a 30°C incubator. After the seeds are white, they are sown in nutrient bowls, 1 seed per bowl. After most of the watermelon seedlings are unearthed, disinfect and accelerate the rootstock seeds in the same way as the scion. After the rootstock seeds a...

Embodiment 2

[0039] (1) Variety selection: In this example, 'Zaojia (84-24)' watermelon was selected as the scion, and 'Jingxinzhen No. 1' gourd was used as the rootstock.

[0040] (2) Preparation of seedling-raising substrate: Take peat and vermiculite in a ratio of 2:1 by volume, add 1.5 kg of nitrogen, phosphorus and potassium ternary compound fertilizer per cubic meter of substrate, mix well as seedling-raising substrate, and pack in 10cm×10cm plastic in the bowl.

[0041](3) Seed germination and sowing: select plump scion watermelon seeds, first sterilize with 1% formalin solution for 1 hour, then rinse with clean water for 3 to 4 times, then soak the seeds in clean water for 6 hours, and finally put them at 28°C Germination in an incubator. After the seeds are white, they are sown in nutrient bowls, 1 seed per bowl. After most of the watermelon seedlings are unearthed, disinfect and accelerate the rootstock seeds in the same way as the scion. After the rootstock seeds are white, i...

Embodiment 3

[0045] (1) Variety selection: In this embodiment, 'Zaojia (84-24)' watermelon was selected as the scion, and 'Cedar' pumpkin was used as the rootstock.

[0046] (2) Preparation of seedling-raising substrate: Take peat and vermiculite in a ratio of 2:1 by volume, add 2.5 kg of nitrogen, phosphorus and potassium ternary compound fertilizer per cubic meter of substrate, mix well as seedling-raising substrate, and pack in 10cm×10cm plastic in the bowl.

[0047] (3) Seed germination and sowing: select full scion watermelon seeds, first use a volume fraction of 1% formalin solution to disinfect for 1 hour, then rinse with clear water for 3 to 4 times, and then place them in clear water to soak the seeds for 6 hours. Put them in a 32°C incubator to accelerate germination. After the seeds are white, they are sown in nutrient bowls, 1 seed per bowl. After most of the watermelon seedlings are unearthed, disinfect and accelerate the rootstock seeds in the same way as the scion. After ...

Abstract

The invention provides a watermelon grafting method, comprising the steps of: first removing growing points and true leaves of a rootstock seedling, vertically downwardly cutting the center of a hypocotyl between two cotyledons by a blade to form a cut; cutting a hypocotyls below a cotyledonary node of a scion watermelon seedling to form a crescent-shaped cut; obliquely laying the watermelon seedling cut to the rootstock seedling cut to enable the crescent-shaped cut to fit one cut of the rootstock seedling, and conducting fixing by a grafting clamp. According to the invention, the root systemof the scion seedling is firstly kept during grafting, and the cut is close to a growing point, so that the survival rate is high; meanwhile, the grafting cut is relatively high and is not easily incontact with and contaminated by soil, thereby facilitating disease-prevention effect of grafting cultivation; and the method is easy to master compared with an inarching method, and the grafting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of watermelon seedling cultivation, and in particular relates to a watermelon grafting method. Background technique [0002] Watermelon (Citrullus lanatus (Thunb.) Matsum.et Nakai) is an important horticultural crop widely cultivated in Cucurbitaceae (Cucurbitaceae) melons. Its fruit is rich in water and sugar, and also rich in minerals and vitamins. It has the effects of cooling heat, quenching thirst and relieving restlessness, and diuresis. It is a good product for cooling down in midsummer. my country's watermelon planting area is large, but continuous cropping obstacles are becoming more and more serious, especially the occurrence of soil-borne diseases, which seriously damage the normal growth of watermelon plants, resulting in reduced yield and quality, and hindering the development of watermelon industry. Watermelon grafting can effectively prevent and control the damage of soil-borne diseases, and ...
