Embodiment 1

[0014] The main summer cultivar "Shangnong Yuqin" in Shanghai was taken as the research object. First, the celery seeds are wrapped into seed packets with two layers of medical gauze, and the volume of each seed packet is 120 cubic centimeters. Then immerse the celery seed pack in hot water at about 55°C for 20 minutes to sterilize the seeds. During this period, the seed pack needs to be turned continuously to make the seeds evenly heated. Then put the above-mentioned sterilized seed pack in water at about 18°C, and soak the seeds for 12 hours. Then carry out sleep-destroying treatment, after soaking the seed packs to drain the water, put them into the freezer at -18°C for 12 hours, then put the above-mentioned frozen seed packs into the fresh-keeping compartment of the refrigerator, and store them at 8°C. Under germination. Open the seed pack once a day during the germination period, in order to carry out exposure treatment while checking the moldy seeds. After 4 consecutiv...

Embodiment 2

[0016] The main summer cultivar "Italian Xiaqin" in Shanghai was taken as the research object. First, the celery seeds are wrapped into seed packets with two layers of medical gauze, and the volume of each seed packet is 120 cubic centimeters. Then immerse the celery seed pack in hot water at about 60°C for 15 minutes to sterilize the seeds. During this period, the seed pack needs to be turned constantly to make the seeds evenly heated. Then put the above-mentioned sterilized seed pack in water at about 20°C, and soak the seeds for 11 hours. Then carry out sleep-destroying treatment, drain the soaked seed packs and freeze them in a freezer at -14°C for 12 hours. Under germination. Open the seed pack once a day during the germination period, in order to carry out exposure treatment while checking the moldy seeds. After 4 consecutive days, the seeds will start to germinate. After 5 days, the germination rate of the seeds will reach more than 95%, that is, sowing, and the yield...

Embodiment 3

[0018] The Shanghai local variety "Huangxinqin" was taken as the research object. First, the celery seeds are wrapped into seed packets with two layers of medical gauze, and the volume of each seed packet is 120 cubic centimeters. Then soak the celery seed packs in hot water at about 58°C for 18 minutes to sterilize the seeds. During this period, the seed packs need to be turned continuously to make the seeds evenly heated. Then put the above-mentioned sterilized seed pack in water at about 25°C, and soak the seeds for 10 hours. Then carry out sleep-destroying treatment, drain the soaked seed packs, put them into the freezer at -16°C for 12 hours, then put the above-mentioned frozen seed packs into the fresh-keeping compartment of the refrigerator, and store them at 9°C. Under germination. Open the seed pack once a day during the germination period, in order to carry out exposure treatment while checking the moldy seeds. After 4 consecutive days, the seeds will start to germ...

Abstract

The present invention relates to a rapid dormancy-breaking method for the celery seed, which belongs to the technical field of the crop cultivation. The celery seed is wrapped by a medical tiny gauze, and is immerged into the hot water at the temperature of 55 to 60 DEG C for disinfection, and then is immerged in the water at a room temperature for ten to twelve hours, and the seed is put into the refrigeration chamber of the refrigerator for dormancy-breaking treatment, and then is put into the freshness-keeping chamber of the refrigerator for pregermination. During the pregermination, the seed shall be undertaken the exposure processing while undertaking the mould examination; five days later, when the germination rate of the seed reaches to more than 90 percent, the seed can be planted. Compared with the traditional temperature-changing treatment and chemical substance treatment, the present invention is more simple and practical, which can greatly shorten the germination time of the seed, improve the germination rate and the germination quality of the seed, thereby resolving the problems such as seed retting, mass plantation, low germination rate and non-seedling.

Description

technical field [0001] The invention relates to a method for rapidly breaking sleep of celery seeds, which is used for off-season cultivation of green leafy vegetables such as celery and lettuce in summer, and belongs to the technical field of crop cultivation. technical background [0002] With the vigorous adjustment of my country's vegetable planting structure, the degree of vegetable industrialization has been continuously improved, and the planting area of ​​summer off-season vegetables has expanded year by year, which has played an important role in increasing farmers' income and ensuring a balanced market supply. Celery is rich in vitamins, minerals and volatile aromatic oils. It has a spicy taste and has the functions of lowering blood pressure and strengthening the brain. It is a vegetable with dual functions of nutrition and medicine. Celery is a cool vegetable and likes cold weather. It is difficult to cultivate in summer, especially difficult for seeds to germina...
