Embodiment Construction

[0012] A kind of method for grafting cucumber of Yunnan black-seeded pumpkin of the present invention comprises the following steps:

[0013] (1) Remove the mucus on the surface of the sterilized cucumber seeds, soak the seeds at 48-58°C, germinate them at 25-28°C for 6-8 hours, and sow them in a nutrient pot for growth when the buds are 0.3-0.5cm long; Black seed pumpkin seeds are sterilized to remove the mucus on the surface, soak the seeds at 75-80°C for 8-12 hours, accelerate germination at 30-33°C for 10-12 hours, and sow them in the nursery when the buds are 0.8-1.0cm long. 6 days or at the same time sowing;

[0014] (2) After 7-9 days of cucumber sowing, start grafting. Use Yunnan black-seeded pumpkin as the rootstock, use a blade to remove the growth point of the rootstock and the axillary buds on both sides, and insert a special bamboo stick 0.5cm vertically in the center of the growth point. The length of the bamboo stick is 4~ 6cm, the front end of the bamboo stick...

Abstract

The invention discloses a method for grafting of a cucumber on a black-seed pumpkin in Yunnan, belonging to the field of crop breeding. According to the method, the black-seed pumpkin in Yunnan is used as a stock, a growing point and axillary buds on two sides of the stock are removed by a blade, a special bamboo stick of 0.5cm is vertically inserted into the center of the growing point and is maintained in a stem, a cucumber seedling is taken, the under-cotyledon part is removed by obliquely cutting at 0.4-0.6cm under the cotyledon of the cucumber seedling for an angle of 25-30 degrees, the bamboo stick is taken out, the cucumber seedling is inserted into a grafting hole, and the cotyledon of the cucumber and the cotyledon of the stock are arranged in a cross-shaped vertical shape; and after grafting is performed, moisture is kept for 3-5 days in an enclosed environment in a greenhouse, the temperature is maintained at 25-30 DEG C at daytime and 18-20 DEG C at night for seedling hardening, then ventilation is performed gradually, and complete ventilation is performed on the ninth or tenth day. The black-seed pumpkin in Yunnan is used as the stock in the method, diseases which can easily occur to certain cucumber seedlings can be eliminated completely, and the stress tolerance and disease resistance can be better improved. Since direct insertion is adopted for grafting, the rate of incidence of adventive roots is very low, and the survival rate of grafted seedlings can be guaranteed to be up to 98 percent.

Description

technical field [0001] The invention designs a plant breeding method, and in particular relates to a method for grafting cucumbers from Yunnan black-seeded pumpkins. Background technique [0002] Pumpkins are mainly divided into black-seeded pumpkins and white-seeded pumpkins. Compared with white-seeded pumpkins, black-seeded pumpkins are used as rootstocks to graft cucumbers mainly in spring and winter, and black-seeded pumpkins are superior to white-seeded pumpkins in certain stress resistance performances. However, at present, cucumbers grafted with black-seeded pumpkins have a high probability of developing adventitious roots. After the adventitious roots of cucumbers take root in the soil, it is easy to further cause fusarium wilt, which brings great harm to production. The current grafting methods include leaning and inserting, and inserting is divided into straight inserting and oblique inserting. Different methods have different effects on cucumber grafting. Conten...
