Problems solved by technology

In a planting cycle, the bulbs need to be transferred back and forth between the field and the flower room many times, which costs a lot of labor costs
In addition, when the bulbs are propagated in the field, they are easily infected with viruses, resulting in a decline in yield and quality; in order to avoid the impact of natural disasters in the field on the quality of filaments, the bulbs must be transferred to the field after the indoor flowering (in mid-November). Bulb growth period (6 months) is seriously insufficient

Embodiment 1

[0024] The saffron bulb of the present embodiment comes from Shanghai Jiaotong University.

[0025] The MS culture medium described in this embodiment has the following specific components:

[0026]

[0027]

[0028] This embodiment includes the following steps:

[0029] 1. In the first ten days of May, put 350kg of saffron bulbs in a culture tray, which is placed on a metal frame, and the area of ​​the culture room is 30m 2 . The culture plate is a 50cm*200cm stainless steel plate, and the upper layer of the culture plate is equipped with a drip irrigation device and a plug-in hygrometer. There are adjustable fluorescent lamps on the training frame. The cultivation frame is divided into 4 layers, and the layer height is 50cm. The temperature of the culture room is controlled by air conditioning.

[0030] 2. The thickness of the matrix is ​​20cm, and the main components in the matrix are earthworm fertilizer, vermiculite, and perlite, mixed according to 7:2:1.

[0...

Embodiment 2

[0038] There is an air convection device in the cultivation room. The saffron bulbs are placed in the hollow tray in the middle, and the tray is fixed on the cultivation frame. The whole plant, including the root system, is exposed to the air and irrigated with nutrient solution spray; the light source is composed of indirect natural light and light. Vacuum freeze drying;

[0039] The fertilizer required for bulb growth is dissolved in water to make a nutrient solution, which is replenished with water and fertilizer by spraying. The water needed for bulb growth is dechlorinated tap water or other clean water resources. The composition of the nutrient solution is: 1 / 10 medium without sugar.

[0040] In this embodiment, the medium used is the same as that in Example 1.

[0041] In this embodiment, the cultivation room is a concrete structure with temperature control equipment inside. There are vents in the walls and no windows on all sides. The air convection device is a b...

Embodiment 3

[0047] This embodiment is substantially the same as Embodiment 2, except that indirect natural light is used during the day and ordinary fluorescent lamps are used at night.

[0048] In the present embodiment, 350kg seed bulbs produce 505 grams of filaments.

[0049] Taking Example 1 as a comparative example, the data of Examples 1 to 3 are compared, as shown in the table below:

[0050] bulb Filigree Example 1 350kg 500g Example 2 350kg 520g Example 3 350kg 505g

[0051] As can be seen from the above data, for the present invention, the solution described in Example 2 is more optimal.

Abstract

The invention discloses a facility cultivation method for saffron. The method comprises the following steps: in a culture room, saffron bulbs are placed in a tray with the middle hollowed-out, the tray is fixed to a culture rack, the entire plant including the root system is exposed to the air, and spray irrigation is carried out with a nutrient solution. A light source is composed of indirect natural light and lamp light. After a shortened dormancy period, a flower bud differentiation period, a flower bud growth period and an extended flowering period, filaments are subjected to vacuum freeze-drying. According to the facility cultivation method, the vegetative growth and reproductive growth of the bulbs are completed indoors, various cultivation conditions can be controlled artificially and accurately, and many problems existing in a traditional cultivation mode can be overcome, and the method is not restricted by geographical conditions and is conducive to large-scale and factory-based production, so that the price of saffron is substantially reduced.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a method for protected cultivation of saffron. Background technique [0002] Saffron, also known as saffron and saffron, is a precious and scarce traditional Chinese medicinal material. It has attracted much attention because of its saffron content. It is known as the most expensive medicinal plant in the world, the best dye in the world, and the most high-grade spices. The State Administration of Traditional Chinese Medicine has listed it as a key development of Chinese medicinal materials. In recent years, the value of saffron in medical treatment, health care, and chemical industry has been fully developed. Due to the huge amount of saffron, the market is in short supply and mainly depends on imports. [0003] my country's saffron adopts a two-stage cultivation model of indoor flower cultivation and field propagation. The cultivation of saffron requires both land reso...
