Abstract
The utility model relates to a tobacco root restriction direct seeding seedling raising disk which belongs to the field of plant growing. The seedling raising disk comprises a disk body, wherein a plurality of seedling raising grooves are uniformly distributed on the disk body. The seedling raising disk is characterized in that each seedling raising groove is of an inverted cone shape, and a water control hole is arranged on a side conical surface at a middle lower part. By matching with corresponding management measures, the seedling raising disk can be used for controlling root system plunging, so that the length of a main root is prolonged, the quantity of uncertain roots is reduced, tobacco seedling damages during transplanting are reduced, the invasion opportunity of pathogenic bacteria of roots and stems is reduced, and the quality of tobacco leaves is improved.
Description
Technical field
The utility model relates to a kind of seedling-cultivating tray, belongs to the plant cultivation field, especially the limit root direct sowing and seedling dish that grows tobacco.
Background technology
In recent years, multiple tobacco tubers disease morbidities such as most of cigarette district bacterial wilt, balck shank, the black corruption of root are heavier, and on the rise; Simultaneously, the former cigarette in roasting back, part cigarette district, particularly the upper leaf nicotine content is too high, and sugared alkali is than inharmonious, and the cigarette compatibility is relatively poor, and the industrial utilization rate is lower.Research shows that group invaded between an early stage most of tubers pathogen transplanting extremely, and infection way is most of to be that wound is invaded; Nicotine mainly synthesizes the root cap in root system, and nicotine content is directly proportional with the quantity of adventive root, and adventive root quantity is many more, and nicotine is synthetic many more.
Comprise disk body like Fig. 2, common live seedling-cultivating tray, be evenly equipped with a plurality of grooves of growing seedlings on this disk body, be provided with bottom outlet in the bottom of the groove of growing seedlings.The seedling-cultivating tray of this structure can make under the most of axial root system of cigarette seedling and prick in grow seedlings furrow soil or the floating pond, and root system is less in the seedling-cultivating tray, and the outer axial root system of seedling-cultivating tray fractures during transplanting; The root system damage is serious, and cigarette seedling self disease resistance is poor after transplanting, and various tubers pathogen root systems are invaded through wound; Environmental condition is fit to back tubers disease and concentrates outburst; Simultaneously, cigarette seedling main root will produce a large amount of adventive root after cutting off, and increase the nicotine synthetic amount.
The utility model content
The purpose of the utility model is to overcome the problem that above-mentioned prior art exists and the limit root direct sowing and seedling dish that grows tobacco is provided; This seedling-cultivating tray can be controlled under the root system and prick; Increase main root length, reduce adventive root quantity, reduce cigarette seedling damage when transplanting; Reduce tubers pathogen infection chance, and improve quality of tobacco.
The technical scheme that its technical problem of the utility model solution is taked is: this tobacco limit root direct sowing and seedling dish; Comprise disk body, be evenly equipped with a plurality of grooves of growing seedlings on the described disk body, it is characterized in that; The described groove of growing seedlings is back taper, is provided with water control hole on the lower side on the sidepiece conical surface.
Described seedling-cultivating tray is that polystyrene processes, and characteristics are that quality is light, and it is corrosion-resistant to carry matrix and cigarette seedling, and certain mechanical strength is arranged.Specification is 60cm * 33cm, and the groove 100 hole/dishes of growing seedlings coil high 5cm.
Tobacco limit root direct sowing and seedling technology is according to cigarette seedling geotropism, to fertilizer property, hydrotropism's principle; Plastic film is laid on top, seedbed, the coating intelligence controlled release fertilizer that uses release profiles and time and each vegetative stage of cigarette seedling in the tobacco seedling dish and match breeding time, and only need spray clear water whole seedling stage; Need not to topdress; Adopt seedling-cultivating tray top atomizing way of supplying water, guarantee to have in the pallet prescribing adequate nutrition and moisture to supply seed germination and tobacco seedling growth, control required moisture in seedling stage through the sidepiece water control hole.
The beneficial effect of the utility model is: because the groove of growing seedlings is back taper, be provided with water control hole on the lower side on the sidepiece conical surface, through control required moisture in control seedling stage and seedling management thereof; The control root system is pricked down, increases main root length, reduces adventive root quantity; Reduce cigarette seedling damage when transplanting, reduce tubers pathogen infection chance, simultaneously; Reduce and plant back nicotine synthetic amount, improve the harmony of tobacco production and value and inherent chemical composition.
Description of drawings
Fig. 1 is the implementation result sketch map of the utility model (the single groove of growing seedlings);
Fig. 2 is the implementation result sketch map of prior art (the single groove of growing seedlings).
Among the figure: 1 disk body, 2 grooves of growing seedlings, 3 water control holes.
Embodiment
As shown in Figure 1.This tobacco limit root direct sowing and seedling dish comprises disk body 1, is evenly equipped with a plurality of grooves 2 of growing seedlings on the described disk body 1, and the described groove of growing seedlings is back taper, is provided with water control hole 3 on the lower side on the sidepiece conical surface.
Described seedling-cultivating tray is that polystyrene processes, and characteristics are that quality is light, and it is corrosion-resistant to carry matrix and cigarette seedling, and certain mechanical strength is arranged.Specification is 60cm * 33cm, the groove 100 hole/dishes of growing seedlings, the about 4.5cm of bore, high 5cm.
Except that new building, the pallet of growing seedlings need be sterilized before use.Spray drenched seedling dish with the formalin solution of 1%-2% or 15% liquor natrii hypochloritis, the stifling 24h of sealing cleans with clear water.
After the seedling dish installed matrix and controlled release fertilizer, the groove of growing seedlings of each seedling-cultivating tray was broadcast 1-2 grain seed with pressing the cave device to press 0.3-0.5 centimetre kind cave in each cave, need not to cover matrix above the seed.
On the smooth furrow face of arrangement, lay one deck mulch film or two films, the balance while laying, lay preceding ground require smooth, do not have native stone, prevent the plastic film damage.
After balance was accomplished, the special use spraying facility high with fogging degree, that water yield is big supplied water, and in the cave of growing seedlings, open fire occurs, guarantees the capsuled seed cracking, improves emergence rate.
Later stage is rationally confirmed watering time, the mode of watering and waters the water yield that according to factors such as weather, nutrition soil water content water control hole 3 can play the effect that the water yield is regulated.
Fig. 1 compares with Fig. 2.The most of root system of Fig. 1 concentrates in the cave of growing seedlings, and well developed root system, is solid netted root system.Root system is less in Fig. 2 seedling-cultivating tray, pricks the bed of growing seedlings under most of axial root system, and the outer axial root system of seedling-cultivating tray fractures during transplanting, and cutting off during transplanting increases tubers disease infection chance.
