Problems solved by technology

[0003] Through research, people have found materials that are resistant to root-knot nematodes in Cucurbitaceae crops. Fig leaf melon is a wild-type Cucurbitaceae plant. The genetic relationship of cucumber is far away, and resistance cannot be utilized through conventional breeding. At the same time, due to the difference in growth rate between the two when grafting, the difficulty of matching and compatibility during grafting limits the application of fig leaf melon as a rootstock material in production.

Embodiment 1

[0026] A kind of cultivation method of cucumber grafted seedling comprises the following steps:

[0027] (1) The fig leaf melon and cucumber seeds (Zhongnong No. 6) were sterilized by immersion in warm soup respectively, and germination was accelerated with sterile water. Fig leaf melon and cucumber were sown in stages, and the sowing period of cucumber was 3 days later than that of fig leaf melon. Fig leaf melon and cucumber were sown in different seedling pots respectively, with sterilized peat: vermiculite (2:1) as Cultivate the substrate, the relative humidity is 70%, and the seedlings are managed under the condition of temperature 25°C.

[0028] (2) When the fig leaf melon is sown for 13 days, the fig leaf melon and cucumber seedling leaves are flattened, and the first true leaf appears. At this time, the fig leaf melon and cucumber have similar stem thickness, the stem thickness is 0.25cm, which is grafted at this time. best time. Choose fig leaf melon as the rootstock...

Embodiment 2

[0031] A kind of cultivation method of cucumber grafted seedling comprises the following steps:

[0032] (1) The fig leaf melon and cucumber seeds (Zhongnong No. 6) were sterilized by immersion in warm soup respectively, and germination was accelerated with sterile water. Fig leaf melon and cucumber were sown in stages, and the sowing period of cucumber was 3 days later than that of fig leaf melon. Fig leaf melon and cucumber were sown in different seedling pots respectively, with sterilized peat: vermiculite (2:1) as Culture substrate, the relative humidity is 75%, and the seedlings are managed under the condition of temperature 26°C.

[0033] (2) When the fig leaf melon is sown for 14 days, the fig leaf melon and the cucumber seedling leaves are flattened, and the first true leaf appears. At this time, the fig leaf melon and the cucumber have similar stalk thickness, and the stem thickness is 0.25cm. At this time, it is grafted. best time. Choose fig leaf melon as the root...

Embodiment 3

[0036] A kind of cultivation method of cucumber grafted seedling comprises the following steps:

[0037] (1) The fig leaf melon and cucumber seeds (Zhongnong No. 6) were sterilized by immersion in warm soup respectively, and germination was accelerated with sterile water. Fig leaf melon and cucumber were sown in stages, and the sowing period of cucumber was 3 days later than that of fig leaf melon. Fig leaf melon and cucumber were sown in different seedling pots respectively, with sterilized peat: vermiculite (2:1) as Cultivate the substrate, the relative humidity is 80%, and the seedlings are managed under the condition of temperature 28°C.

[0038] (2) When fig leaf melon was sown for 15 days, the cotyledon leaves of fig leaf melon and cucumber seedlings were flattened, and the first true leaf appeared. At this time, the stalks of fig leaf melon and cucumber were similar in thickness, which was the best time for grafting. Choose fig leaf melon as the rootstock, and cultivat...

Abstract

The invention provides cucumber grafting seedlings as well as a cultivation method and application thereof. The cultivation method comprises the steps of taking a melabergourd as a rootstock, taking acucumber as a scion, and cultivating the cucumber grafting seedlings resistant to threadworms by utilizing a simple, convenient and fast grafting method. The control effect of the cucumber grafting seedlings on root-knot nematode is up to 76.7%, and the cucumber grafting seedlings can be used for control over root-knot nematode diseases in the production of cucumbers. The cultivation method of the cucumber grafting seedlings effectively solves the problems of direct matching performance and affinity between the rootstock and the scion and has relatively good affinity, a grafted cucumber has aroot-knot nematode controlling effect in production, the grafting seedlings have a remarkable yield increasing effect, and the method can solve the problem that the control over the root-knot nematode is difficult in the production of the cucumbers, has a huge application prospect in the production, and is conducive to realizing high-yield, safe and pollution-free production of the cucumbers.

Description

technical field [0001] The invention belongs to the technical field of vegetable seedling cultivation, and in particular relates to a cucumber grafted seedling and a cultivation method and application thereof. Background technique [0002] Cucumber root-knot nematode disease mainly harms the root system of cucumbers, forming root knots of different sizes. When the disease is severe, the plants are obviously dwarfed, the melons are few and small, the leaves turn green and turn yellow, and finally the plants die, which affects the quality and yield of cucumbers. Cause serious impact, cause 20-30% reduction of production every year, when severe, fail to harvest. Currently, chemical pesticides and disease-resistant breeding are commonly used in production to prevent and control root-knot nematodes. However, excessive use of pesticides will cause serious harm to the human body and the environment. The use of resistance breeding is the most economical and efficient way to control ...
