Embodiment 1

[0020] 1. Select Jinchun No. 5 dense thorn cucumber variety with strong plant growth, high disease resistance and high yield as scion, and white-seed pumpkin as rootstock. The rootstock should be sown 3-5 days earlier than the scion. When the first true leaf of the rootstock is the same size as a five-cent coin, and the two cotyledons of the scion have just unfolded, the grafting begins.

[0021] 2. First, align the rootstock with the cotyledon as the benchmark, 20-30 seedlings in a bundle, tied with a rubber band; cut off 5cm below the cotyledon with a sterilized sharp knife, discard the rhizome and the root below, and dip the wound within 5 minutes Sterilize the root-promoting solution for 10 seconds, with a dipping depth of 5 cm; then stand it in the activated carbon powder that has been pulverized to 180 mesh and heated to 40-50° C. for 30 to 40 minutes.

[0022] 3. Then remove the growth point of the rootstock, and use a special grafting stick to insert it obliquely downw...

Embodiment 2

[0026] 1. Choose the cucumber varieties with crispy and tender taste and marketable Dutch Dedoxing fruit as the scion, and choose the Japanese new Tosa F1 as the rootstock. The rootstock should be sown 3-5 days earlier than the scion. When the first true leaf of the rootstock is the same size as a five-cent coin, and the two cotyledons of the scion have just unfolded, the grafting begins.

[0027] 2. First, align the rootstock with the cotyledon as the benchmark, 20-30 seedlings in a bundle, tied with a rubber band; cut off 5cm below the cotyledon with a sterilized sharp knife, discard the rhizome and the root below, and dip the wound within 5 minutes Sterilize the root-promoting solution for 10 seconds, with a dipping depth of 5 cm; then stand it in the activated carbon powder that has been pulverized to 180 mesh and heated to 40-50° C. for 30 to 40 minutes.

Abstract

The grafting cultivation of cucumbers has the advantages of improving the soil-borne disease resistant capacity of plants, enhancing the cold resistance of the plants, overcoming continuous cropping obstacles, improving yield and the like, and has a great significance for the cultivation of protected areas of cucumber facilities. The invention provides a method for cultivating strong root systems of grafted cucumbers. In the method, field planting is performed after roots of rootstocks of the grafted cucumbers are cut off, and the rootstocks are induced to generate new strong root systems while grafting union, so in the production, rejuvenation is quick after the field planting, the low-temperature resistance performance and early-stage growth potential of seedlings are high obviously, the seedlings are resistant to premature senescence in the later stage, the rate of fruit setting is greater than that of the conventional seedlings, and the weight of a single cucumber is heavy. Contrast tests indicate that compared with the conventional graft seedlings, the fruit bearing peak period of the grafted cucumber seedlings subjected to root-cut cultivation is prolonged by 3 to 5 days, so the yield is improved by over 5 percent.

Description

technical field [0001] The invention belongs to the technical field of cucumber cultivation, in particular to a cultivation method for cultivating a strong root system by cutting off the root of a grafted cucumber rootstock and then transplanting it. Background technique [0002] Cucumber is an important global popular vegetable, and its cultivated area ranks fourth after tomato, cabbage and onion. Among them, about 241,000 hectares of cucumbers are cultivated in China, accounting for 28% of the world's cultivated area, ranking first in the world. In the protected cultivation of facilities in northern my country, cucumber is among the best because of its high yield, remarkable economic benefits and stable market price. "If you want to get rid of poverty, build a greenhouse, and if you want to have money to spend, quickly grow cucumbers" This folk saying reflects the status of cucumbers in the cultivation of facility vegetables. [0003] Cucumber grafting cultivation has th...
