Problems solved by technology

[0004] According to the current saffron workshop-style cultivation mode, in addition to the high cost of long-term investment in bulbs and cultivation houses, there are still many problems in the saffron industry, such as high requirements for saffron planting technology, fertilizer and water management, temperature control, etc. Many factors, such as humidity control, climate influence, and differences in farmers' knowledge and technical capabilities, have resulted in low corm yields when saffron is cultivated in the open field, and the light, temperature, and humidity of indoor flowering are greatly affected by the external weather, and the flower development is poor. The stamens are small, and a large number of dead flowers are affected by the low temperature before and after the full flowering period, resulting in reduced production. The yield and quality of saffron cannot be effectively guaranteed; Taking pistils and cutting buds is still a whole process of manual operation, the production efficiency is extremely low, and the amount of labor is very large. In addition, seasonal labor conflicts are prominent, and labor wages are rising year by year. The price of safflower is more than 2 times, which seriously restricts the healthy development of my country's saffron industry

Embodiment 1

[0034] Example 1 Mechanization of planting bulbs in the open field

[0035] In 2010, saffron was planted in Chongming County, Shanghai. The fertile land without crushed stones and bricks was selected as the planting site. The soil quality was yellow and sandy, and the depth of the soil layer was more than 30cm. At the beginning of October, tractors were used for deep plowing of the land, with a depth of more than 20cm. In mid-October, use a tractor to drive a fertilizer applicator to apply base fertilizer. If the bulb size is 25g or less, apply 5 tons of decomposed organic fertilizer per mu, 20kg of nitrogen fertilizer element nitrogen, 30kg of superphosphate, and 15kg of potassium fertilizer element potassium as base fertilizer; the bulb size is Apply 8 tons of decomposed organic fertilizer per acre above 25g, 40kg of nitrogen fertilizer element nitrogen, 50 kg of superphosphate, and 30kg of potassium fertilizer element potassium as base fertilizer. The rotary tillage ridge ...

Embodiment 2

[0038] Example 2 Cultivation of stamens in industrialized interiors

[0039] The saffron bulbs harvested in Example 1 were classified by a vibrating sieve type bulb classifier into four grades of less than 10g, 10-25g, 25-40g and greater than 40g. Soak and wash to remove the soil attached to the saffron bulbs, and use 70% thiophanate-methyl wettable powder 600 times to sterilize the seeds by soaking for 20 minutes. The sterilized saffron bulbs are placed in trays, graded according to different specifications, and placed on indoor cultivation racks with a floor height of 8-15cm. An automatic control system is used to control the air relative humidity, temperature and light in the saffron cultivation room, in which the air relative humidity is controlled between 80±5%, and the temperature control adopts the process control method of first rising and then falling. The temperature in the late dormancy period is 20-28°C; the temperature in the assimilative bud differentiation peri...

Embodiment 3

[0040] Example 3 Mechanized open-field planting of corms

[0041] In 2011, saffron was planted in Chongming County, Shanghai. The fertile land without crushed stones and bricks was selected as the planting site. The soil quality was yellow and sandy, and the depth of the soil layer was more than 30cm. In mid-October, tractors were used for deep plowing of the land, with a depth of more than 20cm. Use a tractor to drive a fertilizer applicator to apply base fertilizer, apply 5 tons of decomposed organic fertilizer per mu if the size of the bulb is 25g or less, 20kg of nitrogen fertilizer element nitrogen, 30kg of superphosphate, and 15kg of potassium fertilizer element potassium as the base fertilizer; Apply 8 tons of decomposed organic fertilizer per mu, 40kg of nitrogen fertilizer element nitrogen, 50kg of superphosphate, and 30kg of potassium fertilizer element potassium as base fertilizer. In the middle and late October, the rotary tillage ridge machine was used to complet...

Abstract

The invention belongs to the technical field of planting the traditional Chinese medicinal materials. The invention discloses an efficient cultivation method of saffron, and in particular relates a standardized saffron planting method including mechanized field corm planting and industrialized indoor stamen culture. The efficient cultivation method of saffron improves the per unit yield of the saffron, and also greatly improves the mechanized operation level, saves the labor, and realizes standardized, mechanized and large-scale production of the saffron; the shortcomings of small-area scattered cultivation, lack of labor for seasonable sudden work and high labor cost of the current manual workshop type cultivation method of the saffron in China are solved.

Description

technical field [0001] The invention belongs to the field of planting Chinese medicinal materials, and in particular relates to a high-efficiency cultivation method of famous and precious medicinal material saffron. Background technique [0002] Saffron (Stigma Croci), also known as saffron, is also called saffron because it was first introduced to the mainland from Tibet. The English name of saffron: Saffron, Japanese name: サフラン, is the style and stigma of the pistil of Crocus sativus L., a plant of the family Iridaceae, and its native place is on the coast of the Mediterranean Sea. According to the "Compendium of Materia Medica", saffron can "promote blood circulation, control depression, and treat palpitations". Therefore, Chinese medicine is used to treat cardiovascular diseases. At present, the main producing areas of saffron are Iran, Greece, Spain and other countries, and only a small amount is cultivated in my country. Due to its extremely low yield and time-consu...
