The soil fertility indices in the table are classified according to the classification standard of the 2 nd general survey of soil across the country. In the standard leaf proportion data of the transplanting current year in the table: < a% means that the standard leaf average proportion is (a-1) to a%; b means that the average ratio of standard leaves is b to (b + 3)%.
As can be seen from the above table test results, the transplanted tree is affected under the condition that the soil fertility index is acceptable (can be close to the lower-middle level)The survival rate of wood is mainly determined by the presence or absence of non-metallic mineral particles and the particle size. By comparing example 2 with comparative example 1, it is apparent that the survival rate of ginkgo biloba is significantly increased as the particle size of the nonmetallic mineral particles is increased. The main reason for this phenomenon is that the particle size of the non-metallic mineral particles can have a significant influence on the air permeability of the transplanting pit, the oxygen content of the soil is significantly improved under the action of the non-metallic mineral particles with large particle size, and the harmful gas exchange rate is increased, so that the transplanting method is beneficial to the development of tree roots after transplanting with ginkgo biloba. And practical comparison shows that the area of the vertical projection plane of the ginkgo crown in the example 2 is obviously larger than that of the comparative example 1, which shows that the development of the root system of the ginkgo crown is far better than that of the comparative example 1, the ginkgo crown is widely distributed in a plane range, the ginkgo crown is favorable for absorbing nutrients with ginkgo, and the survival rate of the transplanted tree is ensured. On the other hand, comparing example 2, comparative example 1(200 mesh) and comparative example 2, it is obvious that the survival rate of the tree of comparative example 2 is the same as that of comparative example 1(200 mesh) under the condition of not adding the non-metal mineral particles, but the detection of the soil shows that the fertility index of the soil of comparative example 2 in the early and middle stages is obviously lower than that of comparative example 1(200 mesh), which indicates that the addition and the adoption of the non-metal mineral particles and the release of the nutrient components in the nutrient rod into the soil improve the fertility index of the soil in a short time, and generate obvious beneficial influence on the growth of the transplanted tree. Comparing the comparative example 3 with the example 3, it can be seen that the selection of the linen non-woven fabric can also have a significant influence on the growth and development conditions of the transplanted trees, which is mainly reflected in two aspects of soil fertility index and standard leaf proportion of the current year of transplantation. In the case of using a high gram weight hemp nonwoven fabric, as in comparative example 3(65 g/m)2) And comparative example 3(80 g/m)2) The standard leaf proportion of the transplanted hemp non-woven fabric is remarkably reduced in the current year, and the soil fertility index is reduced in the whole period, so that the high gram weight hemp non-woven fabric can be used for preventing the release of nutrient components of the nutrient bar, the soil fertility index is remarkably reduced particularly in the early middle period, but the soil fertility index is improved after the hemp non-woven fabric is gradually degraded in the later period. And comparative example 3(10 g/m)2) The test group shows thatUnder the condition of the linen non-woven fabric with low gram weight, the soil fertility index is remarkably improved at the early stage and is even better than those of the experimental groups of the embodiments 1-7, but the soil fertility index is remarkably reduced in a medium-long period, which shows that the nutrient substances are easily lost due to the excessively fast release, the soil fertility index is poor in stability, and certain adverse effects are actually generated on transplanted trees. Therefore, in conclusion, the adoption of the linen non-woven fabric with proper gram weight is also very critical for the nutrition bar to generate the effect of stable and sustained release. Similarly, examples 6 and 7 demonstrate the above findings. Examples 4 and 5 on the other hand show that the fibrilia has more remarkable advantages compared with the rest of the plant fibers, which is also based on the excellent porosity of the fibrilia and is generated by improving the gas exchange and nutrient exchange capacities of the nutrient bar and the soil.
In addition, the comparative example 4 in the table uses the existing fully degradable polyurethane packaging bag as the degradable outer package, and the data are obviously degraded in all aspects. Research shows that the main reason for the problem is that the fully degradable polyurethane packaging bag has poorer air permeability compared with a hemp non-woven fabric packaging bag, and the fully degradable polyurethane packaging bag cannot generate effective gas exchange with soil although large non-metal mineral particles are sampled, and meanwhile, nutrient exchange is influenced by the fully degradable polyurethane packaging bag until nutrient substances can be effectively released after the fully degradable polyurethane packaging bag is degraded.
2. Arranging the nutrition bars obtained in the examples 1-7 and the comparative examples 1-4 into 16 groups, arranging 10 parallel samples in each group, punching and burying the groups in street tree pits after five years of planting, placing 4 nutrition bars in each pit, connecting the top of each nutrition bar with a ventilation cap, and exposing the ventilation cap on the soil surface; the street trees are Huangshan goldenrain trees, the trees stop flowering for two years before implementation, and the flowering condition is observed after implementation for one year, which is shown in table 2.
TABLE 2
Ratio of flowering before implementation One year flowering proportion
Example 1 ＜10 % ＞50 %
Example 2 ＜10 % ＞50 %
Example 3 ＜10 % ＞60 %
Example 4 ＜10 % ＞50 %
Example 5 ＜10 % ＞60 %
Example 6 ＜10 % ＞65 %
Example 7 ＜10 % ＞60 %
COMPARATIVE EXAMPLE 1(200 mesh) ＜10 % About 18～29 %
COMPARATIVE EXAMPLE 1(120 mesh) ＜10 % About 19 to 27%
COMPARATIVE EXAMPLE 1(60 mesh) ＜10 % About 26 to 34%
COMPARATIVE EXAMPLE 1(1.0 mm) ＜10 % About 42 to 48 percent
Comparative example 2 ＜10 % About 16 to 22%
Comparative example 3(65 g/m)2) ＜10 % About 20 to 29%
Comparative example 3(80 g/m)2) ＜10 % About 19 to 26%
Comparative example 3(10 g/m)2) ＜10 % About 44 to 52%
Comparative example 4 ＜10 % ＜15 %
From the test results in the table 2, it can be seen that the flowering proportion of the tree rejuvenation is similar to that of the tree transplanting test results in the table 1, and the tree rejuvenation test results show that the nutrition bar has relatively high stability for tree transplanting and tree rejuvenation and can produce excellent effects.
Example 8
Based on the example 2, the comparative test of transplanted trees is carried out simultaneously by replacing the diatomite particles used in the example 2 with pumice, vermiculite, ceramsite, brick particles and tile particles. Because the number of transplanted trees is not enough, only 4 parallel samples are arranged in each group of the test group adopting pumice, vermiculite, pearlite, ceramsite, brick grains and tile grains.
The test results show that the standard leaf proportion data of the transplanted year are reduced by about 1-2% and the rest parts are basically equivalent in the two test groups for sampling pumice and vermiculite, while the standard leaf proportion data of the transplanted year are improved by about 2% in the test group for sampling ceramsite, but the soil fertility index of the transplanted year is reduced to the middle-upper level in the soil fertility index, which indicates that compared with diatomite particles, the ceramsite has the effect of slightly improving the release and exchange efficiency of nutrient substances, or the diatomite particles have unique superiority due to the characteristic that the diatomite particles can be used as nutrient substances. In the test groups of brick grains and tile grains, the standard leaf proportion data in the current year of transplantation are reduced by about 2-3%, and the rest parts are basically equivalent.
The test results show that even if the non-metallic mineral particles are the same, the difference in use effect exists, the use effect is relatively optimal to be the diatomite particles and the ceramsite, and the diatomite particles and the ceramsite respectively emphasize long-term stable supply and short-term efficient release of tree nutrition.
