Problems solved by technology

[0005] In order to solve the technical problem that the ratio of male to female plants cannot be controlled or the ratio of male plants is too high in the process of raising seedlings of Trichosanthes chinensis, the inventor finally invented a new technology for cutting seedlings of Trichosanthes chinensis through a large number of experiments, which can effectively solve the problem of In the process of building seedlings, the ratio of male to female plants cannot be controlled or the ratio of male to female plants is too high

Embodiment 1

[0016] (1) Preparation of ear-picking plants. 5 days and 10 days before ear picking, the ear picking plants were sprayed with DuPont Ebao diluted 1200 times + 0.25% potassium dihydrogen phosphate solution respectively.

[0017] (2) Picking ears. Select the segments with green mature leaves, full axillary buds, and not yet germinated segments on the plants that are growing sturdy and disease-free. Use pruning shears to cut the cuttings, cut at 2.5cm below the nodes, and then cut them with a sharp knife. The cut is a 45-degree smooth surface, leaving 5cm on the knot to cut vertically.

[0018] (3) Accelerating root treatment. Soak the 1-1.5 cm lower part of the cut cuttings with 0.1% naphthaleneacetic acid + 0.015% 6-BA for 8 seconds.

[0019] (4) Preparation of cutting substrate. The substrate for cuttings is made of perlite, river sand and loam in a ratio of 1:1:1, and is soaked in a potassium permanganate aqueous solution with a mass fraction of 0.1% for 24 hours, then drained a...

Embodiment 2

[0024] (1) Preparation of ear-picking plants. 5 days and 10 days before ear picking, the ear picking plants were sprayed with DuPont Ebao diluted 1800 times and 0.28% potassium dihydrogen phosphate solution respectively.

[0025] (2) Picking ears. Select the segments with green mature leaves, full axillary buds, and not yet germinated segments on the plants that are growing vigorously and without diseases and insect pests. Cut the cuttings with pruning shears, cut them at 2.3cm below the nodes, and then cut them with a sharp knife. The cut is a 49-degree smooth surface, and 4.5cm is left on the knot to cut vertically.

[0026] (3) Accelerating root treatment. Soak the lower 1-1.5 cm part of the cut cuttings with 0.08% naphthalene acetic acid + 0.012% 6-BA for 6 seconds.

[0027] (4) Preparation of cutting substrate. The substrate for cuttings is made of perlite, river sand and loam in a ratio of 1:1:1, and is soaked in a potassium permanganate aqueous solution with a mass fractio...

Abstract

The invention discloses a cuttage seedling-culture technology for Chinese trichosanthes. The method comprises preparation of scion-picking plants, scion picking, root promoting processing, preparation of a cutting medium, cuttage and cuttage management. Gender of Chinese trichosanthes seedlings cultured by the cuttage seedling-culture technology and gender of the scion-picking plants are identical, the cuttage survival rate is 85-95% and is high, and gender-controlled type seedling culture of the Chinese trichosanthes is achieved. The scion-picking time is between the last ten-day period of October and the first ten-day period of November, the cuttage survival rate of the Chinese trichosanthes seedlings is improved, and production of the scion-picking plants is not influenced.

Description

Technical field [0001] The invention relates to a plant seedling raising technique, in particular to a new cutting seedling raising technique of the Cucurbitaceae plant Trichosanthes. Background technique [0002] Trichosanthes is a plant belonging to the genus Trichosanthes of the family Cucurbitaceae, alias Trichosanthes, Latin name Trichosanthes kirilowii Maxim It is a dioecious plant. An important economic value of Gualou lies in the use of female plants to produce fruit. Therefore, more female plants are required for production, and fewer male plants. The ratio of female plants to male plants is generally required to be 10: 1 or so. [0003] At this stage, the seedling technology of Jialou seedlings is mostly used, but after the seeds germinate, about 70% of the seedlings produced are male plants, and it is difficult to distinguish between male plants and female plants before flowering. In this way, there are often more male plants than female plants in cultivation, which wa...
