Embodiment
In order to understand the present invention further, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these describe just for further illustrating the features and advantages of the present invention, instead of limiting to the claimed invention.
The embodiment of the invention discloses the cultural method of a kind of asparagus, comprise the following steps: using the polyethylene rope of 180-360 silk as seedling rope, described seedling rope is soaked successively in water and in the urea of 0.1%; Select the marine site that trend is unimpeded, stormy waves is less, described seedling rope is set in described marine site; Asparagus seed is soaked 10-30 hour in fresh water, then in nutrient solution, soaks 0.5-2 hour, described nutrient solution comprises: carbonic hydroammonium, magnesium sulfate, boric acid, titanium sulfate, potassium chloride, cobalt nitrate, adenine, indolebutyric acid; Asparagus seed after soaking is passed seedling rope, and press from both sides cluster seedling every 8-10cm, 10-12cm is exposed at two ends, takes flat method of supporting to cultivate, the lifting rope on the seedling rope two ends clipped and the floating ridge is linked, at seedling rope two ends suspension dropstone; Gather in the crops when frond length reaches 80-100cm, selected part frond is comparatively thick, color is purple black in seed, proceed point seedling and cultivate.
Preferably, the time that seedling rope soaks in water is 5-30 hour, is more preferably 10-25 hour, is more preferably 15-20 hour; The time that seedling rope soaks in the urea of 0.1% is preferably 5-30 hour, is more preferably 10-25 hour, is more preferably 15-20 hour.
Preferably, described marine site below neap full sea line in tide band sea area and low tide band sea area.The seawater transparency in the marine site that the present invention selects is preferably 0.7-1.5m, and water temperature is 8-30 DEG C, and salinity is 26-32%, and nitrogen content is not less than 50mg/m
3.
Preferably, asparagus seed is soaked by the present invention in fresh water, can prevent the generation of damage by disease and insect on the one hand, stimulate growth of seedling simultaneously.The time that asparagus seed is soaked in fresh water is preferably 15-25 hour, is more preferably 18-22 hour, is more preferably 20 hours.
Preferably, the present invention also comprises: the asparagus seed after soaking in fresh water is soaked 1-20 hour in triacontanol, and wherein, soak time is preferably 2-15 hour, is more preferably 5-10 hour.
The triacontanol that the present invention adopts can affect growth, the Differentiation and development of asparagus, and main manifestations is: the activity that can strengthen enzyme, impels seed sprouting, improves germination rate; Strengthen photosynthetic intensity, improve chlorophyll content, increase the accumulation of dry matter; Promote Crop mineral matter element, improve protein and sugar and divide content, improve product quality etc.
Preferably, described nutrient solution is prepared as follows: carbonic hydroammonium, magnesium sulfate, boric acid, titanium sulfate, potassium chloride, cobalt nitrate, adenine and indolebutyric acid are added to the water, and stirs 20-60 minute, obtains nutrient solution after filtration.Preferred, the weight ratio of described carbonic hydroammonium, magnesium sulfate, boric acid, titanium sulfate, potassium chloride, cobalt nitrate, adenine and indolebutyric acid is 1-3:1-3:2-5:3-6:1-3:2-5:1-4:0.1-1, be more preferably 1-2:1-3:3-4:4-5:2-3:3-4:2-3:0.3-0.7, be more preferably 2:2:3:5:2:3:2:0.5.
Adenine is easy to be absorbed by plants, the decomposition of can promote cell division, improve anti-injury ability, suppress chlorophyll, nucleic acid, protein, protects green anti-old.Indolebutyric acid can be absorbed by asparagus, but mobility is very little, is not easily decomposed by indoleacetic acid oxidase, and the biologically active duration is longer, and, act synergistically with other nutrient components, promote the growth of asparagus seedling.
The present invention adopts above-mentioned nutrient solution, further suppress the generation of damage by disease and insect, the especially blue sub-natural enemy of fish, on the other hand for the growth of asparagus provides sufficient nutrition, facilitates the growth of asparagus.
The folder seedling amount that the present invention adopts preferably uses 180g asparagus with every meter of seedling rope, after rejecting assorted algae when the asparagus of seedling by about 18g be a tuftlet through seedling rope, during folder seedling, prevent exposure in sunshine and frond drying; Marine seedling of hanging should avoid direct sunlight, takes flat method of supporting to cultivate, the lifting rope on the seedling rope two ends clipped and the floating ridge is linked, hangs dropstone at seedling rope two ends.
In asparagus breeding process, regulate asparagus water layer according to transparency, cultivation water layer is consistent with sea area transparency, and the 5-6 month, transparency is greater than 200cm, and water layer should control at below 140cm; In July, transparency is between 160cm-190cm, and asparagus is suspended between water layer 80cm-100cm, and growth better; In August, transparency is between 150cm-200cm, and asparagus is suspended between water layer 70-90cm; In September, transparency is between 210cm-220cm, and asparagus is suspended on water layer 100cm.
Weight according to asparagus regulates buoyancy, and the water layer that asparagus is hung remains on 80cm-110cm; The direction of adjustment raft frame is parallel with trend or distinguished and admirable direction; Within every 2-4 days, check that seedling rope is with or without coming off with seedling rope with or without winding.
As can be seen from above scheme, the present invention is using carbonic hydroammonium, magnesium sulfate, boric acid, titanium sulfate, potassium chloride, cobalt nitrate, adenine and indolebutyric acid as nutrient solution, fresh water, triacontanol and nutrient solution is utilized to process asparagus successively, inhibit damage by disease and insect on the one hand, facilitate the growth of asparagus seedling on the other hand, and without assorted algae erosion, quality better, output is high.Therefore, the cultural method of asparagus provided by the invention improves marine ecosystem environment, other biological is multiplied and lived propagation, has larger economic worth.
