Performance test
The kelp seedlings were cultivated by the methods of cultivation for growing and winding the seedlings according to examples 1 to 4, and the density and length of the seedlings when the drum grower was taken out of the warehouse are shown in table 1. (in calculating the seedling density at the time of ex-warehouse, not only the number of the surface kelp seedlings but also the unraveling of the seedling raising ropes 2 to form 3 rope threads, counting the bottom seedlings therein.)
TABLE 1 seedling Density and seedling size at delivery of the Drum seedling feeder
As can be seen from Table 1, when the roller seedling raising device is taken out of the warehouse, the density of the kelp seedlings on the vinylon and polyethylene blended rope is the highest, and the densities of the kelp seedlings on the polyethylene rope, the vinylon rope and the nylon rope are relatively lower.
Example 1 the space utilization of the roller seedling raising device and the white curtain used in the conventional seedling raising is shown in table 2.
TABLE 2 comparison of space utilization of white curtains for the drum type nursery sock growing machine and the conventional nursery sock growing in example 1
As can be seen from Table 2, the space used by the roller seedling raising device in example 1 of the present application is 2.62 times that of the white-shade seedling raising device in the same seedling raising space.
According to the method, the cultivation method of raising the seedlings and winding the seedlings by cultivating the kelp by using the 'roller seedling raising device' is optimized, and on one hand, the number and the yield of the seedlings in unit area are improved by increasing the length of the kelp cultivation seedling rope 3 in unit area and performing rotary cultivation operation; on the other hand, the seedling raising rope 2 attached with the kelp seedlings is conveniently and quickly wound on the kelp breeding seedling rope 3, so that the long-dragon type breeding is realized, the operation step that the kelp seedlings are separated and then are taken down one by one and then are transferred into the breeding seedling rope 3 in the traditional method is omitted, and the seedling separating cost is saved.
Setting 3 parameters of the roller seedling raising device, wherein the diameters of the roller seedling raising device are respectively 5 cm, 6.3 cm and 7.5 cm, and the roller seedling raising device adopts PVC pipes; meanwhile, the diameters of the seedling raising ropes 2 are respectively set to be 0.5 mm, 0.8 mm, 1 mm and 1.5 mm, the seedling raising ropes 2 are all made of nylon wires, the winding operation of the roller is realized by using winding equipment, and a plurality of roller seedling raising devices with different specifications are obtained in total.
As can be seen from FIGS. 6 and 7, the density of the seedlings wound around the roller with the diameter of 7.5 cm and the nylon rope of 1-1.5 mm is high. The length of the kelp seedling on the roller seedling raising device is within the range of 0.2-1 mm, and the length of the kelp seedling on a roller with the diameter of 5 cm is relatively large. In fig. 6 and 7, the letters a, b, c, d, e, f, g, h, i are defined as: the same letters exist, and no significant difference exists; different letters exist, and the difference is remarkable. The results of the anova showed that the drum diameter had no significant effect on the seedling density, while the nylon cord diameter had a significant effect on the seedling density.
Comprehensively judges the uniformity of received light, the simplicity of operation, the final rate of emergence and the length, when the diameter of the roller seedling raising device is 5 cm, the density of the roller seedling raising device is lower than that of the roller seedling raising device with a large diameter, but the attachment time can be controlled by prolonging the attachment time before seedling picking. The seedling raising device adopting the roller has the advantages of good light receiving effect and large kelp seedling length, and the diameter of the seedling raising device is 5 cm. However, when the diameter of the seedling raising rope 2 is too small, the artificial root attachment space is small, the attachment is not firm, and as can be seen from table 1, the diameter range of the seedling raising rope 2 is controlled to be best between 3 and 4 millimeters, and the effect of raising seedlings by using the vinylon and polyethylene blended rope in the embodiment 1 of the application is best.
Aiming at the production indexes of the length and the density of the kelp seedlings when the kelp seedlings are taken out of the warehouse, the parameters of the material of the breeding seedling rope 3, the diameter of the roller seedling raising device, the diameter of the breeding seedling rope 3 and the like are optimized, and the methods and the parameters of seedling picking density control and light intensity control in the seedling raising process are optimized. Aiming at the seedling density index of the roller seedling raising device in the seedling winding process of the breeding seedling rope 3, the moving speed of the hollow circular tube 1 and the rotating frequency of the hollow circular tube 1 during seedling winding are optimized.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
