Corm and sowing propagation of saffron

Saffron, also known as saffron (details), is a very famous precious flower, not only has a high medicinal value, its ornamental value is also very high. Generally speaking, saffron is mainly propagated by bulbs and sowing. The editor will introduce the two propagation methods of saffron in detail for you.

Saffron

1. Divide the ball to breed. It is generally carried out from August to September, the mature corm has several main and lateral buds, and after flowering, it expands from the base of the leaf clump to form a new corm. After the aboveground part withered in summer, the corm was dug out, graded, dried and stored. The early planting time is beneficial to the formation of strong seedlings. Each mature bulb has several main buds and lateral buds. When planting, big balls and small balls of more than 8 grams should be planted separately. Bulbs weighing less than 8 grams can not blossom in the same year and need to be cultivated for another year. The pot should choose the spring flower species with bulb weight of about 20 grams in October, and the flowerpots with an inner diameter of 15 centimeters can plant 5 to 6 balls in each pot. After planting, put it outside for maintenance. It takes root after about two weeks and moves to a place with sufficient indoor light and fresh and moist air. New Year's Day can blossom before and after. The residual flowers should be picked immediately after flowering to avoid nutrient consumption, and compound fertilizer solution dominated by phosphorus and potassium should be applied once or twice to promote bulb growth and sturdiness. Continue to maintain normally, until the aboveground part turns yellow in summer, take out the bulb and store it after drying. Saffron can also be water-raised and ornamental, in the same way as daffodils (details).

2. Sowing and reproduction. As saffron is not easy to seed, it needs artificial pollination to get seeds. After the seeds are ripe, the seeds will be sown in the open field seedbed or pot with harvest. The seed sowing density should not be too high, and it is better to be sparse, because the plant needs to grow balls and generally cannot be dug within 2 years. It often takes 3 to 4 years from seed sowing to plant flowering.

Distribution, sowing and propagation of saffron

Saffron is a horticultural variety of hibiscus, which has a certain ornamental value and florescence for the whole year. Due to the strong branching ability of saffron, it is resistant to pruning and has a wide range of adaptation to the soil. Friends who like to breed crocuses themselves can choose to divide balls and sow seeds to breed.

Saffron

First, separate ball reproduction

The bulbs were propagated with bulbs. In the first and middle of May, when the aboveground part of saffron had not yet fully returned to seedling, the corms were dug up, separated according to size, and stored in a ventilated and dry place. Planted in the first and middle of September. Soaking the bulb with benzoate diluent before planting and treating the soil with an 100 mu has a good effect on eliminating nematodes in the soil and preventing the spread of diseases and insect pests. Early planting bulbs germinate first and then sprout, early emergence is beneficial to plant growth and development; late sowing is first germinated and then rooted, late emergence, seedling growth is poor. The size of the bulb is closely related to whether it blooms or not. The bulb weight of less than 8 grams generally does not blossom, and the number of flowering flowers increases with the increase of corm weight. The number of leaves, the number of leaves and the size of leaves are also related to the size of the corm. Therefore, the seed stem of saffron must be selected and planted at different levels. Generally divided into more than 25 grams, 16 grams 25 grams, 8 grams 18 grams, less than 8 grams of four files to facilitate management. Soaking the seeds and stems with 5% lime water for 20 minutes before sowing can prevent the terminal bud rot; soak the seeds with 25% carbendazim and 3000 times dicofol or 40% dimethoate for 20 minutes and soak the seeds immediately to control rot and Robin root mites. Before planting, remove the lateral buds on the corms, leave 1 top piercing for the bulbs less than 16 grams, 2 shoot buds for 16 grams and 25 grams, and 3 terminal buds for those more than 25 grams, and plant them in flat beds. The yield of saffron is related to planting density and depth. If the planting is too shallow, the number of new bulbs is more, the individual is small, and the flowering bulbs are less; if the plants are too deep (such as 10 cm deep), the new corms are larger, but the number of flowering bulbs is also reduced. For this reason, the planting density and depth of saffron should be planted separately according to the size of the bulb. The bulbs of less than 8 grams should be planted with row spacing of 9 cm 12 cm, plant spacing of 3 cm and depth of 3 cm 4.5 cm; for bulbs of 8 grams or 25 grams, row spacing should be 12 cm, plant spacing 6 cm, depth 6 cm; corms above 25 grams should have row spacing of 12 cm, plant spacing of 9 cm and depth of 6 cm. When planting, trench and sow according to the above depth, put the bulb into the above density, the main bud up, gently press into the soil, cover the soil to smooth. The seed consumption per hectare is about 10500 kg.

2. Sowing and propagation

As saffron is not easy to seed, it needs artificial pollination to get seeds. After the seeds are ripe, the seeds will be sown in the open field seedbed or pot with harvest. The seed sowing density should not be too high, and it is better to be sparse, because the plant needs to grow balls and generally cannot dig within 2 years. It often takes 3-4 years from seed sowing to plant flowering.

How to reproduce, sow and divide balls of saffron

How to propagate saffron 1. Methods of sowing and propagation

Because saffron is not easy to seed, it needs artificial pollination to get the seed. After the seed is ripe, it will be sown in the open field seedbed or pot.

The seed sowing density should not be too high, and it is better to be sparse, because the plant needs to grow balls and generally cannot dig within 2 years. It often takes 3-4 years from seed sowing to plant flowering.

2. The method of ball-dividing propagation.

The method of bulblet propagation of saffron is generally carried out from August to September. The mature bulb has several main and lateral buds, and after flowering, it expands from the base of the leaf clump to form a new corm. After the aboveground part withered in summer, the corm is dug out, graded, dried and stored.

In general, each mature bulb has several main buds and lateral buds, and bulbs of more than 8 grams can be planted separately from small ones. Bulbs weighing less than 8 grams can not blossom in the same year and need to be cultivated for another year.

The pot should choose the spring flower species with bulb weight of about 20 grams in October, and the flowerpots with an inner diameter of 15 centimeters can plant 5 to 6 balls in each pot. After planting, first put outdoor maintenance, about two weeks later take root, moved into indoor light, fresh and moist place, New Year's Day can blossom before and after.
