Description

A kind of waters floating bed and cultivation method

Technical field

The present invention relates to a kind of agriculture cultivation technology, refer in particular to a kind of waters floating bed and cultivation method that adopts dual-layer polystyrene foaming to make.

Background technology

China has just had the application of similar floating bed planting technology in history, as far back as three states " frame field " is just arranged the epoch, and its method is organized in together as the cultivation carrier for utilizing the withered bar of plant.Applied widely, can under environment such as fish pond, reservoir, river, take and make.Though simple in structure, be easy to build.But little, the undercapacity of its supporting power is easy to destroy under abominable natural conditions.

It is domestic that what carry out the earliest that the natural water area plant cultivation attempts is units such as lake, Chinese Academy of Sciences Nanjing and geological research institute, academy of agricultural sciences, Fujian Province.Its floating bed structure is that foamed polystyrene board is done float carrier, plants behind the earth of upper berth, utilizes plant residue to make buoyancy aid before having overcome and to the pollution again that water body causes, helps scale.The Song Xiang of China Paddy Rice Inst just waited the people to invent the method for the artificial floating bed hydroponics of natural water area terrestrial plant in 1993.But the shortcoming that said method exists is: 1) to cultivate plant seedlings in advance, transplant, and the plant death after inevitably occurring in its process transplanting, and increased managerial difficulty.2) plant is fixing firm inadequately, causes the disengaging between matrix, plant, floating bed easily.3) need irregular labor management.

Summary of the invention

The purpose of this invention is to provide a kind of waters floating bed and cultivation method, it is with cheap materials such as polystyrene, gauze, mao bamboon, iron wire, the floating bed that structural strength and pliability are all good.It is with low cost and intensity is high, have enough pliabilities, supporting power is big, sound construction.

The device of realizing the object of the invention is made of materials such as dual-layer polystyrene foaming, gauze, mao bamboons, gauze is placed in the middle of two foamed polystyrene boards, two-layer up and down foaming plate is beaten the culture hole in different apertures respectively, wherein the lower floor aperture is less than the upper strata, and whether the standard in aperture, upper strata is by using the stem thickness of matrix and plant to be the main reference index.Pitch-row is as the criterion with the best planting density of plantation plant.At last with mao bamboon as peripheral fixture, make last fixing of iron wire.

The inventive method is specially: the difference temperature required according to different seed germinations, the sowing time of selection floating bed plant.The seed that choicest quality is good is positioned on the gauze of special floating bed, uses before the floating bed and floating bed to be placed in the water 2-3 days, behind the seed germination, continues to be allowed to condition on the floating bed and grows, until finishing the growth and development of plant process.

The invention has the advantages that:

1) with low cost and intensity is high, have enough pliabilities, supporting power big, sound construction, even not fragile under the abominable natural conditions yet.In the bad weather that summer in 2005, typhoon landed, adopt between paddy rice that the lamina floating bed device transplants plantation and floating bed to occur separating, a large amount of rice plants are poured on the floating bed, and floating bed device itself also suffers to a certain degree to damage, and occurs damaged; Novel live doubling plate floating bed then degree of safety is crossed bad weather, and device does not occur damaged, is fixed well between rice plant and floating bed.

2) Du Te double-layer foamed plate holder gauze structure had both guaranteed the demand of plant to water, had also satisfied gas permeability, had guaranteed the demand of root system to oxygen.So the developmental process from seed germination to the plant later stage, needn't worry to occur anoxic or lack of water.

3) mao bamboon is corrosion-resistant, distortion or rotten can not appear in long-term the placement yet in the water, and after fully absorbing water, weight and buoyancy of water at itself are following mutually, make floating bed sinking degree that gauze is contacted with the water surface, seed can fully be absorbed water in the early stage, and be the suction of the later stage root system of plant condition that facilitates.Removed former floating bed from and will regulate draft by hanging weight.

4) device can reuse.After the plant full maturity, floating bed can be pulled out water and plant is separated with it, after the separation floating bed be dried, can reuse, save cost, increase operation rate.

5) adopt this cultivation method to save the labour, when for example paddy rice is as cultivated plant, adopt the method for transplanting, need wash root, rice transplanting is to the floating bed plant fixing hole, at last floating bed is put into water, if this process one man operation needs 4-5 hour time at least for the wide floating bed of 2.5m*1.2m; Exempt from support method and adopt, then need only be in culture hole on demand amount sowing, just floating bed can be put into water after mixing the back covering with reed foam and 1: 1 ratio of husk, whole process need only dozens of minutes can be finished.Especially when floating bed quantity is many, transplanting will be put into water after keeping plant vigor need transplant one, many continuous operation easier strengthen, if adopt the new support method of exempting from, and can all sowing be good and finish connection on land and put into water again in all floating beds.

Embodiment

This method is an example to cultivate paddy rice in the man-made lake in the school in Jiangsu University.

Select for use foamed polystyrene board to do carrier, upper strata foamed polystyrene board (6) is 5cm, and lower floor's foamed polystyrene board (5) is 3cm.With the overlapping placement of two-layer foaming plate, beat culture hole (3) by pitch-row 20cm*22cm on it, the aperture is 3cm.Lay gauze (1) between two-layer foaming plate, gauze is the normal domestic screen window, uses mao bamboon (2) and iron wire to fix on every side.The floating bed cellar area is 2m*1m, plants 32 clumps.

The difference temperature required according to different plant seed germinations, the sowing time of selection floating bed plant.Earlier floating bed was placed before using in the man-made lake 3 days, peripheral fixture mao bamboon is fully absorbed water.Weight of suction back mao bamboon self and buoyancy interact like this, will make floating bed sinking to a certain degree, and the foamed polystyrene board of lower floor is immersed in the water, and the water surface just contacts gauze or covers gauze slightly.
