Problems solved by technology

However, grafting seedlings have high requirements on grafting technology, environmental conditions and management measures. The grafting method in the current technology is not efficient and has poor repeatability. In actual production, there are still problems such as high morbidity, low survival rate and weak growth of grafted seedlings.

Embodiment 1

[0023] A kind of watermelon grafting method, comprises the following steps:

[0024] A. Rootstock breeding;

[0025] B. Seed soaking to accelerate germination: After 5 days of rootstock breeding, decontaminate the melon seeds, soak the seeds with the supernatant of lime water for 25 minutes, and then rinse with clear water. The seeds are sterilized, then rinsed and soaked; the sterilized seeds are sterilized with 450 times of carbendazim liquid for 0.5 hours. After the sterilized seeds are washed with clean water, they are placed in warm water at 42°C, stirred for 10 minutes, cooled naturally, and then soaked for 4 hours. After soaking the seeds, rub the seeds repeatedly in warm water at 25°C to remove the mucilage on the surface of the seeds to facilitate germination. After soaking the seeds, drain the water and put them into cloth bags for 38 hours at 25° C. and a humidity of 60% rh to germinate the seeds.

Embodiment 2

[0034] A kind of watermelon grafting method, comprises the following steps:

[0035] A. Rootstock breeding;

[0036] B. Seed soaking to accelerate germination: After rootstock breeding for 7 days, decontaminate the melon seeds, soak the seeds with the supernatant of lime water for 25 minutes, and then rinse with clear water. The seeds are disinfected, then rinsed and soaked; the disinfected seeds are disinfected with 500 times of carbendazim liquid for 1 hour. After the sterilized seeds are washed with clean water, they are put into warm water at 47°C, stirred for 10 minutes, cooled naturally, and then soaked for 5 hours. After soaking the seeds, rub the seeds repeatedly in warm water at 30°C to remove the mucilage on the surface of the seeds to facilitate germination. After soaking the seeds, drain the water and put them into a cloth bag for 40 hours at 30° C. and a humidity of 65% rh to germinate the seeds.

Embodiment 3

[0045] A kind of watermelon grafting method, comprises the following steps:

[0046] A. Rootstock breeding;

[0047] B. Seed soaking to accelerate germination: After rootstock breeding for 10 days, decontaminate the melon seeds, soak the seeds with the supernatant of lime water for 36 minutes, and then rinse with clear water. The seeds are disinfected, then rinsed and soaked; the disinfected seeds are disinfected with 550 times of carbendazim liquid for 1.5 hours. After the sterilized seeds are washed with clean water, they are placed in warm water at 53°C, stirred for 15 minutes, cooled naturally, and then soaked for 6 hours. After soaking the seeds, rub the seeds repeatedly in warm water at 35°C to remove the mucus on the surface of the seeds to facilitate germination. After soaking the seeds, drain the water and put them into a cloth bag for 43 hours at 32° C. and a humidity of 70% rh to germinate the seeds.

Abstract

The invention discloses a watermelon grafting method. The watermelon grafting method includes the following steps: carrying out stock breeding; soaking seeds for accelerating germination, wherein at the time five to ten days after stock breeding, the seeds are sterilized, rinsed and soaked; growing seedlings; hardening the seedlings, wherein thin films of minor arches are lifted up in the daytime to enable the seedlings to be irradiated by sunlight, and put down at night; carrying out grafting, wherein main leaves and growing points of stock are removed, then holes are slantly formed in the top ends of the stock in an inserted mode through bamboo sticks with the diameter the same as that of scions, then the proper scions are selected, the bamboo sticks on the stock are pulled out, and the scions are inserted into the holes; managing the grafted seedlings, wherein the indoor temperature is controlled to range 24 DEG C to 29 DEG C in the daytime and controlled to range 18 DEG C to 23 DEG C at night, and the humidity is controlled to range from 70%rh to 85%rh; removing sprouts of the stock, wherein the lateral sprouts germinated from the stock are removed at the time ten to fifteen days after grafting is carried out; hardening the seedlings before transplanting is carried out, wherein low-temperature hardening is carried out on the seedlings at the time seven days before transplanting is carried out; carrying out transplanting. By means of the watermelon grafting method, the watermelon grafting survival rate can be increased.

Description

technical field [0001] The invention relates to the field of grafting, in particular to a watermelon grafting method. Background technique [0002] Watermelon is cultivated in both north and south of China. Watermelon is a dicotyledonous flowering plant with a vine-like plant shape and feathery leaves. The fruit it bears is gourd, which is a kind of fleshy fruit unique to Cucurbitaceae melons. It is a false fruit developed from the lower ovary of three carpels with parietal placenta. The main edible part of watermelon is the well-developed placenta. The outer skin of the fruit is smooth, green or yellow in color, the juicy flesh is red or yellow, and white flesh is rare. Watermelon is cold in nature and sweet in taste; it has the effects of clearing heat and relieving heat, promoting body fluid to quench thirst, diuresis and relieving restlessness; Alcoholism embolism. The skin can also be used for cooking and medicine. [0003] In recent years, watermelon continuous cr...
