Container seedling raising method for sand-upland plants
Technical Field
The invention relates to the technical field of plant cultivation, in particular to a container seedling method for sand upland plants.
Background
One commonly seen characteristic of psammophytes, particularly psammophytes shrubs, is the formation of divided stems. For example, the stem of an artemisia, a peganum harmala and a overlord can be split into several parts. The split forms several separate parts, some of which die due to the different conditions of the niche encountered may survive and continue to grow.
The xerophyte has a greater ratio of cortex to pericycle, the cortex in the stem is wider than that of the mesophyte, and the vascular bundle is tighter around the narrow marrow. This configuration may be an adaptive mechanism, especially before the cork layer is formed, the thick cortex may be involved in protecting vascular tissue from drought. The increase of the thickness of the cortex in the stem of the xerophyte is in sharp contrast with the decrease of the number of the cortex in the root. Some chenopodiaceae plants with nodes, such as horsetail and halaxylon, have a fleshy cortex and are capable of photosynthesis. When the summer is dry, the wood can be gradually peeled off, and a cork layer is generated in phloem parenchyma cells, so that the internal vascular tissue is protected.
Some sand plants develop parenchyma, which stores water, in addition to photosynthetic green tissue in their stems. Such stems are usually characterized as fleshy, colloidal matter and crystals within the cells. The stem and branch parts of the psammophytes are thicker and heavier due to the fleshy stem of the psammophytes, and the stem and branch parts of the psammophytes are easy to break when the cultured seedlings are taken out from the seedling culture container for cultivation; some xerophytes have sharp spines on stems and branches, so that the xerophytes cannot be transplanted and cultivated quickly easily, and the survival rate is reduced due to insufficient water supply in the cultivation process, so that improvement is urgently needed.

and sixthly, when the transplanting destination is reached, the bottom box 1 and the upper cover 2 are moved to the transplanting ground from the transfer trolley, the tray 3 is lifted up after the upper cover 2 is removed, at the moment, cultivation personnel cooperate to detach the lower barrel 4-2 in the cultivation barrel 4 in a rotating manner, the tray 3 is integrally placed into a pre-dug planting pit (because the nutrition soil 10 can be shaped into an integral body in the seedling cultivation process, and after the lower barrel 4-2 is detached, the nutrition soil 10 can still be ensured to be an integral body and not to fall off under the action of large external force), then, soil is filled to the lower edge of the upper barrel 4-1, the tray 3 is lifted up integrally to be separated from the nutrition soil 10 where the seedling roots are located, and soil filling is continued until the nutrition soil 10 is completely covered.
After adopting above-mentioned structure, this embodiment beneficial effect does:
1. the split type cultivation barrel 4 is adopted, so that the sand upland plants cultivated in the container can be transplanted and cultivated collectively and rapidly, the transplanting efficiency is improved, and meanwhile, the loss of water and nutritional ingredients in the nutritional soil 10 is avoided;
2. in the transportation process, environmental moisture and seedling moisture are supplied in time, the humidity of the environment from the nursery garden to the planting field and the moisture required by the growth of the seedlings are guaranteed, and the survival rate of the seedlings after transplantation is improved;
3. the plurality of cultivating barrels 4 are integrally formed in the tray 3, so that a plurality of seedlings can be conveniently and integrally transplanted into the transplanting pit, the direct contact of hands with the seedlings is avoided, the hands are prevented from being stabbed by thorns on seedling stems, and the transplanting safety is improved;
4. adopt split type cultivation bucket 4, can realize cultivating the cyclic utilization of bucket, practice thrift the cost, reduce its pollution to the environment.
The seedling survival rate and the transplanting survival rate (all the seedlings of the sand upland plants act on ten seedling raising containers) are tested by using the seedling raising container, the seedling raising method and the control group (the control group adopts the seedling raising container in the prior art, namely, the seedling raising container does not contain water storage cotton, and water in the environment in the transplanting process is not added in the transportation process, after the seedlings reach the destination, the seedlings are taken out of the seedling raising container one by one and then transferred to a transplanting pit), the test results are shown in fig. 5, and as can be seen from fig. 5, by adopting the seedling raising method of the embodiment, the seedling survival rate (mean value) and the transplanting survival rate (mean value) are far higher than those of the control group.
