Planting method of potted saffron

Saffron, also known as saffron, saffron, and so on, many farmers do not grasp the key technical points, resulting in longer and smaller bulbs, fewer flowers, lower and lower yield per mu, and give up planting because of inefficiency. With the crocus in full bloom, the pace of spring is getting closer and closer to us. It is expected that early spring flowers such as spring, mountain peach, mountain apricot, magnolia and other early spring flowers will bloom one after another in the middle and second half of this month, and people will usher in the season of spring flowers. Here are some planting points:

Saffron 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.

Saffron likes a mild and cool climate, afraid of heat, and is more resistant to cold. Like fertile sandy loam, avoid stagnant water, and use bulbs to propagate in our country. Saffron is a shallow root plant with fibrous roots. Choose land with sufficient light, loose and fertile land, and avoid continuous cropping. The temperature in northern China is low in winter, so the soil surface can be sprayed with a new high-fat film 600 murmur800 times, which can preserve soil moisture and prevent evaporation, sun and drought, heat preservation and freezing, soil layer hardening, suffocation and isolation of diseases and insect pests.

Corm treatment saffron corms have main buds and lateral buds, main buds blossom, lateral buds do not bloom, lateral buds must be thoroughly removed. Spraying Zhuangtiling at the bud stage makes the buds strong and the petals enlarged, thus achieving high yield.

Chemical treatment can prevent diseases and insect pests. The main disease of saffron is rot disease. Using fungicide and new high lipid film to make medicine solution, soaking the bulb before planting can greatly improve the utilization rate of effective components of pesticides and fertilizer, do not fear sun exposure and evaporation, can adjust the absorption of water saving, drought and rain prevention.

PS: the original species of saffron has medicinal value, but the experts in the botanical garden especially remind you that the saffron planted in the botanical garden are artificially cultivated horticultural varieties, can only be ornamental, do not have medicinal value. I hope you can enjoy the flowers and love them more, so that more people can enjoy the beauty of saffron.
