Description
Technical field
The present invention relates to technical field of aquaculture, and in particular to a kind of cultural method of lotus rhizome field intercropping cray.
Background technique
Cray is economic freshwater shrimps, because meat flavour is delicious wide welcomed by the people, but because of its omnivorousness, the speed of growth it is fast,
Adaptable and absolute competitive advantage is formed in local environment, range of ingesting includes water plant, algae, aquatic elder brother
Worm, animal carcass etc., food are also killed each other when deficient scarce.It causes it destructive very strong local species ecologic competition advantage.
Lotus rhizome is heliophile, not shade tolerant, requires illumination sufficient in breeding time, entire breeding time can not water shortage, sprout
Bud growth phase requires shallow water, as plant enters the vigorous growth stage, it is desirable that water level is gradually deepened to 30-50cm.Lotus rhizome exists
The substrate and water quality in pond can be improved when growth, while can make to generate a large amount of planktonic organism in water, and cray is miscellaneous
Feeding habits, the planktonic organism that can be preyed in water improves water quality, and the excrement of cray can provide fertilizer abundant for lotus rhizome,
The relationship that mutual reciprocity and mutual benefit can be formed between lotus rhizome and cray, effectively improves the utilization rate of soil and water resource.
Currently, the method that existing lotus rhizome cray cultivates jointly, but the method that existing lotus rhizome cray cultivates jointly is only
It can cultivate in a season, high yield is not achieved in the cultivation of cray, and needs to dig annular ditch or right-angled intersection ditch in lotus rhizome field when cultivation, right
Field is destroyed than more serious, and infrastructure cost is relatively high.And the cultural technique that this mode uses is, germinates in lotus kind and founds leaf
Phase allows cray to fall in ditch and cray is not allowed to press from both sides bad lotus bud using the water level in lotus field is lowerd, but this idea is to compare
Utopian, because cannot be below 4cm lotus Tian Liye phase water level is minimum, such cray can not complete all to fall in ditch, small
Lobster still can still will cause certain injury to lotus bud in the activity of lotus field.
Summary of the invention
The object of the present invention is to provide a kind of infrastructure is at low cost, and cray and lotus rhizome may be implemented double to produce high good harvest
A kind of lotus rhizome sugar intercropping cray cultural method.
A kind of cultural method of lotus rhizome field intercropping cray, comprising the following steps:
(1) construction lotus rhizome cray supports pond altogether；Lotus rhizome field is selected, by the padded formation ridge of the surrounding in selected lotus rhizome field soil,
And setting protective net is enclosed in ridge, open up inlet and outlet in the bottom surface of ridge, and small dragon is set in lotus rhizome field
Shrimp raises area；Selected lotus rhizome field is preferably 1 year or time longer lotus rhizome plantation field, plants the water retention property and water-quality ratio in field
Preferably, illumination is sufficient, and the pH value of soil keeps neutral meta-acid；
(2) lotus rhizome field is carried out disinfection processing, and applied fertilizer to the subsoil to the lotus rhizome field after disinfection；
(3) it launches cray shrimp seedling to cray raising area in annual 2-3 month to be raised, cray to be put
After shrimp seedling, the good chicken manure of fermentation maturity is applied into lotus rhizome cray and is supported in pond altogether, when cray it is long to 28-32g when, by small dragon
Shrimp is transferred out of cray raising area and is raised to selling, and supplements cray shrimp seedling into cray raising area, to cray
It is long to 28-32g when, cray is transferred out of cray raising area and is raised to selling, management is repeated in September part, turns
The cray in cray raising area is removed, and male and female crays parent kind is launched to cray raising area and cultivates shrimp seedling, the
Started in 2 years 2-3 months to catch cray shrimp seedling.
Further, in step (1), by the surrounding padded 60-70cm of soil in selected lotus rhizome field, the width of padded ridge
For 28-32cm.The setting of ridge ensures the splendid attire needs of lotus, lotus root, cray.
Further, in step (1), the cray raising Qu Youmi mesh sheet is made, the bottom in cray raising area
Portion is inserted into lotus rhizome field, and the top in cray raising area is lower than ridge 2-3cm.
Further, in step (1), the cross-sectional area in cray raising area is the 1/3-1/2 of lotus rhizome field area.
Cray is set and raises area, the cray that different size may be implemented separately raises, and can prevent cray from destroying lotus rhizome bud, residual
Evil is similar.Reduce the damage to soil, and cost is lower.
Further, in step (1), after choosing lotus rhizome field, calamus is planted in the border in lotus rhizome field, is placed on ridge
Solar energy lures worm desinsection instrument, and osmanthus fragrans are planted on ridge.The plantation of calamus can provide food for cray, and can reach
To the effect of expelling parasite desinsection.The plantation of osmanthus fragrans can increase fragrance for lotus seeds, and sun gear, which lures worm desinsection instrument, to be small dragon with desinsection
Shrimp provides natural bait.
Further, in step (2), 10-20 days before launching shrimp seedling, limewash is uniformly sprayed into lotus rhizome field to it
Carry out disinfection processing, and the amount of sprayed limewash is 70-80kg/ mus, after to be sterilized, applies fermentation maturity into lotus rhizome field
Cow dung.The cow dung of fermentation maturity can provide nutritional ingredient abundant for the growth of lotus rhizome, and generating a large amount of planktonic organisms is small dragon
Shrimp juvenile prawn provides bait, and lime water energy is lotus rhizome field, pool disinfection, can be cray supplement calcium, shell convenient for cray.
Further, in step (3), the injected volume of cray shrimp seedling is 23-28 pounds/acre.
Further, in step (3), when cray it is long to 28-32g when, cray is transferred to cray and is supported in pond altogether
Region in addition to cray raises area.The long cray to 28-32g is transferred to cray to support altogether in pond except cray is raised
The region other than area is supported, prevents from growing fast biggish cray and tortures the slow immature cray of growth, and by biggish cray
It is shifted, can continue to launch the realization coproduction of cray seedling in cray raising area.
Further, in step (3), the ratio of the male and female cray parent kind is 2-3:1.
Further, in step (3): the injected volume of the male and female cray parent kind is 15-20kg/ mus.
The invention has the benefit that a kind of cultural method of lotus rhizome field intercropping cray of the present invention is not necessarily in lotus rhizome
Ditching in field will not damage field, and cost is lower.And a kind of lotus rhizome field intercropping cray of the present invention
Cultural method, the cray cultivated will not damage to the lotus rhizome in pond is supported altogether, that is, be not in that cray destroys lotus rhizome
The phenomenon that bud, is to separate cultivation between cray seedling and larger cray, avoids the phenomenon that prawn tortures shrimp, adopt
It with the method for staying small removal distortion shrimp greatly is sold, allows and forms symbiosis between cray and lotus rhizome, achieve the purpose that the high good harvest of double productions, and
Quick succession planting may be implemented in cray.
