Planting techniques of saffron: a detailed explanation of high-yield planting

Saffron is an important medicine for national key development, but growing saffron is a technical activity, because saffron has strict requirements on the environment, and it is difficult for beginners to raise it well. Let's take a look at the planting techniques of saffron.

I. growth environment

Saffron is a subtropical plant, like a warm and humid climate, can withstand cold, semi-shade, but afraid of extreme heat, stagnant water, need plenty of sunlight. The most suitable growth temperature is 15 degrees, and the flowering temperature is about 16 to 20 degrees. The planted soil should be loose, fertile and well drained. If the sticky weight of the soil will affect the growth and development of saffron.

II. Methods of reproduction

There are two main methods of saffron: bulb propagation and sowing propagation.

1. Bulb propagation: it is usually carried out from August to September every year. After the saffron is ripe, there are multiple main and lateral buds in the bulb. The bottom of the foliage expands and a new bulb is formed. After the saffron withered in summer, the dried bulbs dug out were stored and planted with larger bulbs in October, which could take root and sprout in about half a month.

two。 Sowing and reproduction: it takes a long time for saffron to sow and reproduce, and it is not easy to seed. Artificial pollination is needed to get seeds, and it takes 3 to 4 years from sowing to flowering, so the method of sowing propagation is generally not used.

III. Planting management

1. Fertilizer and water management: about 20 days after planting, saffron should be watered with 2000 kilograms of human and animal manure per mu. If you encounter drought, you can mix more water appropriately. The saffron turns green in the middle of February next year, and each mu of land needs to be applied with 3000 kilograms of human and animal manure. Since March, it has entered an exuberant stage, spraying 0.2% potassium dihydrogen phosphate every 10 days, and spraying 2Mel 3 times in a row.

two。 Moisture: saffron should maintain sufficient soil moisture after sowing. If it is in the north, it should be treated with anti-freezing irrigation before winter, and then irrigated again in April of the following year to meet the growth needs.

3. Anti-freezing: although saffron can withstand cold, it will freeze to death if the temperature is too low, so it needs to be covered with hay and plastic film to build wind barriers.

4. Remove lateral buds: saffron will have lateral buds in the process of growth, so it is necessary to remove lateral buds in time and insert a knife into the soil to remove the leaves.

5. Pest control: saffron growth when the disease and insect pests are relatively few, generally in the spring time to prevent, if you encounter rot, it is necessary to use 5% bacillus 800 times liquid pouring. And prevent rats and rabbits from eating saffron leaves.

Saffron is relatively delicate, if you are careless in planting, it is likely to affect the yield, and there will be fewer and fewer flowers. When planting saffron, it is best to consult and learn with an open mind, so as to ensure the yield.
