Embodiment 1

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

[0017] (2) Ear picking. On a plant that grows robustly and has no pests and diseases, select a section with green mature leaves, full axillary buds, and not yet germinated as cuttings. Use pruning scissors to cut the cuttings, cut off at 2.5cm below the node, and then use a sharp knife to cut the cuttings. The mouth is cut to a smooth surface at 45 degrees, leaving 5 cm on the node and cut vertically.

[0018] (3) Root-promoting treatment. Soak the lower 1-1.5 cm part of the cut cuttings with 0.1% naphthalene acetic 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, prepared in a ratio of 1:1:1, soaked in 0.1% potassium permanganate aq...

Embodiment 2

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

[0025] (2) Ear picking. On a plant that grows robustly and is free from diseases and insect pests, select a segment with green mature leaves, full axillary buds, and not yet germinated as cuttings. Use pruning scissors to cut the cuttings, cut them off at 2.3 cm below the node, and then use a sharp knife to cut the cuttings. The mouth is cut to a smooth surface at 49 degrees, leaving 4.5cm on the node and cutting vertically.

[0026] (3) Root-promoting 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, prepared in a ratio of 1:1:1, soaked in 0.13%...

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 technique for growing seedlings of plants, in particular to a new technology for growing seedlings by cuttings of the Cucurbitaceae plant Trichosanthes. Background technique [0002] Trichosanthes is a plant of the genus Trichosanthes in the family Cucurbitaceae, also known as Trichosanthes, Latin name Trichosanthes kirilowii Maxim , is a dioecious plant, an important economic value of Trichosanthes is to use female plants to produce fruit, so the production requires more female plants and fewer male plants, and the ratio of female plants to male plants is generally required to be 10: 1 or so. [0003] At this stage, Trichosanthes seedlings use more seedling technology, but after seedlings are germinated, about 70% of the seedlings are male plants, and it is difficult to distinguish male plants from female plants before flowering. Like this, the male plant is often more than the female plant in cultivation, which wastes man...
