Problems solved by technology

[0004] In order to solve the problems that existing grafting methods have requirements on scion size, strict management requirements after grafting, and low survival rate if management measures are not in place, the present invention provides a grafting method for improving the survival rate of watermelon grafting. The grafting method adopts The grafting method without rooting and mounting has broad requirements for scions, simple post-management, survival rate ≥ 98%, and grafted seedlings grow quickly, which is very suitable for grafting watermelon and other crops

Embodiment 1

[0027] Embodiment 1: the inventive method compares with conventional grafting method (inserting)

[0028] Operation steps of the present invention:

[0029] (1) Variety selection: the present embodiment selects "Xinong No. 8" watermelon as the scion. "Syngenta Strong Roots" gourd was used as rootstock for grafting.

[0030] (2) Preparation of seedling-raising substrate: mix coir peat and vermiculite into a composite substrate in a ratio of 1:1 by volume, and then pack them in 50-hole hole trays, leaving 1.5-2cm at the top, which is convenient for covering soil and watering after sowing;

[0031] (3) Scion seedling raising: scion seedling raising selects the local main watermelon variety "Xinong No. 8", and soaks the seeds in warm soup (the seeds are poured into warm water of 50-55°C, and constantly stirred to make the water temperature drop to 25-30°C); Then soak in 500 times of potassium permanganate solution for 15 minutes for disinfection, wash the sterilized seeds with c...

Embodiment 2

[0049] Embodiment 2: the inventive method compares with conventional grafting method (inserting)

[0050] Operation steps of the present invention:

[0051] (1) Variety selection: the present embodiment selects "Jingxin series Double Star" watermelon as the scion. "Qingyan Rootstock No. 1" white-seeded pumpkin was used as grafting rootstock.

[0052] (2) Preparation of seedling-raising substrate: mix coir peat and vermiculite into a composite substrate in a ratio of 1:1 by volume, and then pack them in 50-hole hole trays, leaving 1.5-2cm at the top, which is convenient for covering soil and watering after sowing;

[0053] (3) Scion seedling raising: scion seedling raising selects the local main watermelon variety "Jingxin Series Double Star", soaking the seeds in warm soup (the seeds are poured into warm water at 50-55°C, and constantly stirred to make the water temperature drop to 25-30°C); Then soak in 500 times of potassium permanganate solution for 15 minutes for disinfe...

Abstract

The invention discloses a grafting method for increasing the watermelon grafting survival rate.The grafting method comprises the steps that scion seeds are sown at one corner of a hole disk to obtain scion seedlings; when two cotyledons of each scion seedling unfold, stock seeds are sown in the middle of the same hole disk of the scions to obtain stock seedlings; when true leaves just come out from the stock seedlings, grafting is prepared; stock growing points and a cotyledon are chopped, and stems are downwards hacked; a stem of the lower portion of each scion is obliquely cut from the root end to the leaf end; each cut scion is inserted into a stock notch, the cotyledon of each stock makes contact with the cotyledon of the corresponding scion in a cross mode, and fixation is conducted through grafting clips.A broken-root-free hitch grafting mode is adopted, requirements for the scions are inexact, final-period management is easy, the survival rate is 98% or above, grafted seedlings can become adult seedlings quickly, and the grafting method is very suitable for grafting watermelons and other crops.

Description

technical field [0001] The invention relates to a grafting method for improving the survival rate of watermelon grafting (rootless grafting method), which is mainly used for watermelon planting and cultivation, and belongs to the technical field of vegetable production. Background technique [0002] Watermelon is an important high-efficiency 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 . Watermelon grafting is an effective production technology measure to overcome the above problems, so it has been widely used in w...
