Method of Monorchid Cucumber vine propagation
This introduction is about the propagation of Monorchid Cucumber, focusing on the method of vine propagation, with the following details:
Monorchid Cucumber is被誉为 "miracle fruit" by people. It is mainly produced in the mountainous areas of Linggui County and Yongfu County in Guilin City, and is a precious local specialty of Guilin. The fruit has high nutritional value, containing abundant Vitamin C (400-500 mg per 100g of fresh fruit) as well as glycosides, fructose, glucose, protein, lipids, etc. Monorchid Cucumber is usually propagated by pressing the vines. The specific operation methods are as follows:
1. Vine pressing time: This depends on the local climatic conditions. Generally, an average temperature of 25-28℃ for ten days, around the time of Bailu to Autumn Equinox, is considered suitable.
2. Selection and cultivation of vine materials: Choose long, vigorous, thick, internode-long, small-leaved, round-tipped, light green vines that hang down from the trellis. These vine materials have a high survival rate, quick tuber growth, and abundant fibrous roots. The vine materials can also be cultivated in a targeted manner. That is, select a strong lateral vine that sprouts from the base of the early stem, allow it to crawl on the ground to a length of 80-100 cm, then pinch the tip to promote the growth of 3-4 lateral vines as vine materials. For good-quality plants with many fruits but no excessive growth vines, which cannot be propagated by vine pressing in the same year, part of the vines should be laid on the ground early in the following spring to promote vine thickening and form good vine materials. To speed up propagation, the tubers planted in the current year can be allowed to crawl on the ground without going up the trellis, with timely tip pinching to promote lateral vine growth, cultivate vine materials, and also increase economic income.
3. Methods of vine pressing:
(1) On-site vine pressing: This means digging a pit near the vine material for pressing. Depending on the amount of vine material, determine the width of the pit. Generally, for one or 3-4 vines, dig a pit 25 cm long, 10-20 cm wide, and 10 cm deep on the ridge, lead the vines into the pit, place the top of the vine in 2/3 of the pit, space each vine 3-4 cm apart, then gently cover with fine soil 3-4 cm higher than the ridge surface, and cover with straw, water the soil, and keep it moist to promote the growth of new roots and tuber expansion.
Vines pressed from Bailu to Autumn Equinox can be harvested after 50-60 days. Cut the vines near the ground, remove the soil, and the tubers can be taken out. Exclude diseased seedlings, grade them into large, medium, and small, place them in a wooden box with sand for storage or choose a dry place for sand storage (with sand moisture content at 5-6% to maintain proper humidity), and prevent frost damage for future use.
(2) Air vine pressing: Also known as off-ground vine pressing, this uses moss as the culture medium. Take a piece of plastic film 20 cm long and 25 cm wide, cover it with a 3 cm thick layer of moss, place the selected vine material's tip in 2/3 of the moss, then roll the vine into a cylinder, tie both ends with rope, and place it in a shaded area on the trellis to avoid direct sunlight. After 50-60 days, around the time of the beginning of winter, cut from the base of the tuber, collect the rolled tubers, and store them indoors for overwintering and future use.
