Description
Technical field
The invention belongs to agriculture field, particularly, relate to a kind of fish-cultivating method in conjunction with plant setting.
Background technology
South China, has in certain water source and water quality is better and irrigation condition is good pool or paddy field and all can put fish in a suitable place to breed.Through carefully feeding, every mu of paddy field can produce paddy rice 400kg, and river crab fish can produce about 200kg, reaches the effect of paddy rice and fish bumper harvests.
The water surface is planted without soil and plants the agrotechnique that thing is fast development in recent years.For the natural environment of the many surface water of south China, more should develop the planting technique of the water surface, to improve income and environmental quality.Soilless culture paddy rice on the water, the off line housing-case of Bound moisture is supported, and is the pattern of still not attempting in prior art.
Artificial floating bed uses water plants as main body, used the principle of soilless culture, realized the technology of water surface planting.Plant cultivation waterborne, because utilize the very large root system of plant of surface area to form dense net in water, has adsorbed the suspension be suspended in water, has formed biomembrane gradually, be absorbed by plants the nutriment becoming self, be conducive to plant growth.On the other hand, artificial floating bed effectively can utilize water surface area, reaches the object of landscape design and water remediation combination.Because this feature of artificial floating bed, artificial floating bed is used for greatly planting of flowers.Utilize artificial floating bed and net cage cover to support to combine, realizing various plants and cultivate and take into account and breed fish, is the technology obtaining better economic benefit, promising greatly.
Summary of the invention
For the weak point that this area exists, the object of the invention is to propose a kind ofly to overlap the foster device combined for vegetables, paddy rice, flower planting and net cage.
Another object of the present invention proposes a kind of vegetables, paddy rice, flower planting and net cage to overlap the method for supporting and combining.
The technical scheme realizing above-mentioned purpose of the present invention is:
Overlap the device of supporting and combining for vegetables, paddy rice, flower planting and net cage, comprising: buoyant block, net cage, cultivating container and securing member;
Described net cage is circle that nylon wire surrounds, that do not go up end face or square container,
Buoyant block is placed at the top of net cage, and buoyant block is placed at the top of net cage, buoyant block is placed in net cage, then couples together with waterproof rope and floating plate net cage, woodbox, place cultivating container with in waterproof rope buoyant block.
Buoyant block places cultivating container.
Wherein, the end of net cage is the same net with side.The end of net cage and side adopt silk screen to make.
Wherein, described buoyant block is cystosepiment, thickness of slab 8-15cm, every square metre of cystosepiment is opened 5-15 hole, places cultivating container in hole.
Wherein, described cultivating container is flowerpot and/or pot for growing seedlings; Kind is spent, the container of the rice that plants vegetables, plants is different.As: the flowerpot of planting India canna is perforate 20-30 cm diameter, because its root system is very flourishing, what water spinach adopted is small perforations, and such as drift net and floating plate, eyelet are suitable at 2-3 centimetre, too little easily falling down is blown away by stormy waves, and planting seedling also needs to fix with mud or sponge.The pot for growing seedlings diameter of rice cultivation is proper at 8-12 centimetre, because the general Mei Wan of its growth and maturity is in 10 cm one strains.
Described flowerpot is plastic material, has porous barrier in flowerpot, and cultivation matrix placed by porous barrier, and described cultivation matrix is the mixture of water-bed mud and fermentation farmyard manure;
Described pot for growing seedlings is plastic material, pot for growing seedlings bottom opening.
Vegetables, paddy rice, flower planting and net cage overlap the method for supporting and combining, and use device of the present invention, the method comprising the steps of:
1) net cage is set in lake or river, 10-30 bar fish supported by the every cubic metre of net cage that breeds fish fry in net cage, inlet specification is 80-120 gram, ecological fish does not need feeding, eat the microorganism of flowing in aquatic vegetable, flowering marsh plants root and drinking water, if that feeds is fixed on cover 60*50 centimetre of automatic feed throw-in machine in the middle of water plants, every day, start was fed 2-3 time, and the available machine time is 5-10 minute.The ratio of fish and plant is that a cubic meter net cage puts 15 tail, 80 grams of small fish.The kind of fish: silver carp, bighead, grass carp, carp, crucian, yellow eel, loach, snakeheaded fish, megalobrama amblycephala and non-crucian carp etc.
2) when vegetables grow to 15-20 centimetre in soil, rise with hand-lifting and plant pot for growing seedlings/flowerpot? if fish culture in net pen generally places a certain proportion of fertilizer at the 1st flowerpot, do not advise increasing fertilizer, because the excretion of fish food has fertilizer, play breeding balanced growth, the strain of every basin one;
Rice seedling grows to 10 centimetres and is transplanted in pot for growing seedlings, or having bud rice paddy seed point in alms bowl, water depth controls all to immerse in the special basin of paddy rice and water at the root of 1 centimetre of paddy rice.
