Greenhouse Chayote Seedling Technology

1 melon breeding method in early November about the melon sets of plastic bags into the basket placed at room temperature, in late November into the temperature of 15 to 25 degrees Celsius at the germination. After early December, when more roots are produced on the top of the seedlings, they should be transplanted into 25 cm diameter pots, one for each pot, and sandy loam should be selected. Put the roots of the melons straight up and plant them in the pots. After the melons are covered with 5-6 cm of fine sand, do not water them for a time to prevent them from becoming rotten. Strictly controlling watering during nursery, mainly relying on nutrients and water in seed melons for seedling growth to prevent leggy and rotten melons. If rotten melon, as long as the seedling root system is normal, that is, gently hold the roots of the seedlings gently, take out the rotten melon, fill the soil and cover well, still does not affect the nursery. Nursery seedling temperature of 15 to 20 degrees Celsius, if the seedlings are long, leave 4 to 5 leaves topping, after issuing lateral buds, retain 2 to 3 vines can be. 2 The method of raising the embryo by light is to peel the seeds from the inside of the fruit and remove the seed coat as seed material for breeding, also called light embryo propagation. The advantage is that after the seed coat is removed, the seedling emergence rate is high, the volume is small, and it is easy to sow, store and communicate seeds, and the seed melon is still edible. The deficiency is due to the insecurity of wintering, and it can only be broadcast in spring. The main points for raising seedlings are: firstly germinating the seeds of the melon, until the development of the melon radicles, germ and cotyledons to a certain extent, the seeds are detached from the fetus, and the melon's suture line splits the small mouth, and the base of the cotyledon bears the fruits out of the germs. At this point the melon cut open and take out the complete seed, germinate down in the diameter of 10 cm, 18 cm long plastic bag, cover about 1.50 cm, film insulation, moisturizing, the temperature of 15 to 25 degrees Celsius is more appropriate, between the dry, Wet, strengthen water management.
