Description
Technical Field
The invention relates to a method for cultivating asparagus, in particular to a method for shortening the cultivation period of asparagus, and belongs to the technical field of seaweed cultivation.
Background
Gracilaria lemaneiformis (Gracilaria lemaneiformis) is a species of Rhodophyta, Gigartinales, Gracilaria, C and N in biomass formed by Gracilaria comprise main components, so that a large amount of C, N, P, K and other main pollutants causing eutrophication of offshore sea areas can be fixed in seawater in the production process, the water quality of a culture area is effectively purified, and meanwhile, the Gracilaria lemaneiformis is also a health-care food with wide development prospect due to high protein, low fat and rich various mineral substances, vitamins and unsaturated fatty acids, is cold in taste, has the effects of softening phlegm and hardening, clearing heat and promoting water, and is also a raw material for extracting agar, so that the Gracilaria lemaneiformis has many unique values in the aspects of nutrition, medicine, biology, aquaculture and the like.
The asparagus is generally cultivated according to the following method: selecting a bay with better wind sheltering conditions and longer illumination, laying a fixed field, piling or anchoring, and then floating a rope for clamping the seedlings by using a floater; clamping the seedlings, clamping the seedlings by using palm cables or ropes which are not easy to fall off, generally clamping 1 seedling by 200 mm, wherein the length of the seedling clamping ropes is determined according to the arrangement condition of the sea area site, the distance between the seedling clamping ropes is 400-600 mm, the two ends of the seedling clamping ropes are fixed by using bamboo bars, and the seedlings are placed in the sea area and then straightened; during the cultivation period, the seedling cables are prevented from crossing each other in time; when the vegetable grows to 500-00 mm, the vegetable is timely collected to prevent the vegetable from being broken by heavy wind waves, and 3-4 times of vegetables can be collected each time.
The asparagus contains rich nutrient substances and has wide application, the demand of the asparagus is continuously increased in recent years, the growth period of the asparagus in the traditional culture method is about 1.5-2 months, the market demand is difficult to meet, the existing solution is to enlarge the culture scale, but the contradiction between the culture area of the asparagus and the large construction environment is increasingly prominent, the traditional culture mode is influenced by sea area environment change, the asparagus is seriously influenced by pests and diseases, and the rotten phenomenon occurs, so the development of the asparagus industry is severely limited.
Disclosure of Invention
In view of the above, the present invention provides a method for shortening the cultivation cycle of asparagus, which promotes the rapid growth of asparagus in a simple and efficient manner, and shortens the growth cycle of asparagus.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for shortening the cultivation period of asparagus comprises the following steps:
1) selecting healthy immature asparagus, washing with clear water for 2-3 times, and washing with sterilized seawater until no foreign algae exists on the surface of microscopic examination;
2) clamping seedlings of the asparagus, introducing diluted seawater into a pool, and soaking the asparagus clamped with the seedlings in the pool for 7-8 hours;
3) and fishing out the soaked asparagus, and suspending the asparagus on the sea surface for continuous cultivation at a position of 20-50 cm.
Further, the diluted seawater is prepared by mixing seawater and fresh water at a volume ratio of 1:1, the water temperature of the diluted seawater is 15-22 deg.C, and the transparency is 20-30 cm.
Further, the soaking operation in the step 2) is soaking by using circulating dilution seawater, and the circulating dilution seawater controls the water flow speed through a constant flow water pump.
Further, soaking to 20-80cm below the liquid level.
Furthermore, the seedling clamping amount of the clamped seedlings is that 200g of asparagus are clamped by a rope per meter, the cluster weight is 12-15g, the cluster distance is 5-10cm, and the clamped seedlings are clamped in the middle of the seedlings.
The cultivation method of the invention utilizes the growth characteristics of the asparagus, firstly, the asparagus is soaked in the desalted seawater to adapt to the environmental change, and the asparagus is cultivated after being hung, thereby promoting the growth speed of the asparagus to the sea surface, simultaneously avoiding the attachment of other miscellaneous algae in the seawater, saving the growth time and the cost of removing the miscellaneous algae, and promoting the development of the asparagus industry.
