3. The invention adopts the tending measures of overall grass splitting, massive ridging, timely topdressing, proper pruning and the like. In the 1 st year of forestation, the first half year and the second half year are respectively selected to be subjected to comprehensive grass splitting once and massive hilling once, massive hilling is carried out in 8 months, and 150 g/plant of compound fertilizer is buried; in the 2 nd year and the 3 rd year of afforestation, the first half year and the second half year are respectively used for carrying out comprehensive grass splitting once in 8 months, 150g of compound fertilizer is applied to the dalbergia odorifera, and the eucalyptus grandis is not topdressed, so that the situation that the growth of the dalbergia odorifera is too fast to inhibit the growth of the dalbergia odorifera is avoided; in the 4 th year of forestation, the grass is fully split once in 8 months in the next half year, 200g of compound fertilizer is applied to the dalbergia odorifera, and the eucalyptus grandis is not applied; in the 5 th year of afforestation, the forest stand is closed, the typhoon resistance of the plants is obviously enhanced along with the growth of the trees, and whether grass splitting and topdressing are carried out can be determined according to the growth condition of the forest stand.
4. The yellow wingceltis has strong sprouting capability, and after the yellow wingceltis is planted, the rhizosphere has a plurality of sprouting strips and the lateral branches of the trunk are thick and strong, and the yellow wingceltis should be pruned in due time to cultivate good dry type. The pruning is preferably carried out by adopting a method of pruning for a plurality of years after the pruning for light, so as to cultivate the excellent and non-saving material of the dalbergia odorifera with the trunk height of more than 5m through reasonable pruning.
5. The average tree height of the dry-supported species of the eucalyptus grandis in the current year can reach more than 3m, the average tree height of the dalbergia odorifera is about 1.5m, and the effect of supporting the upright growth of the main trunk of the dalbergia odorifera can be preliminarily achieved after one year of afforestation due to the rapid growth of the eucalyptus grandis in the early stage; at the end of 3 years of afforestation, competition between the trunk-supporting tree species and the target tree species is obvious, the effect of supporting the upright growth of the main trunk of the dalbergia odorifera is obvious, and the canopy density of the eucalyptus grandis is about 0.3; at the end of 4 years of afforestation, competition between the trunk supporting tree species and the target tree species is violent, the effect of supporting the upright growth of the main trunk of the dalbergia odorifera is good, and the canopy density of the eucalyptus grandis is about 0.4; at the end of 5 years, the canopy density of eucalyptus grandis was about 0.5. When the canopy density of the trunk tree species reaches 0.4, the growth of the target tree species is obviously inhibited, and the first adjustment is started to reduce the number of the trunk tree species.
The method for adjusting the number of the variety of the trunk-supporting tree comprises the following steps: at the end of 4 years of forestation, the number of intermediate cut trunk-supporting tree species is about 35%, and the trunk-supporting tree species is hugeThe number of retained eucalyptus urophylla plants is 180. hm -2 210 strains hm -2 The canopy density of the eucalyptus grandis after intermediate cutting is about 0.2; when the forest stand is grown for 8-9 years, the canopy density of the eucalyptus grandis tree is about 0.6, the trunk-supporting tree species can obviously inhibit the growth of the target tree species, the number of the trunk-supporting tree species is reduced by adjusting for the second time, the number of the trunk-supporting tree species is about 45% by thinning, and the number of the reserved eucalyptus grandis strains is 90 hm -2 120 strains hm -2 The canopy density of the eucalyptus grandis after thinning is about 0.2.

Experimental example 1 comparison of growth of seedlings in pure forest and cutting seedlings in mixed forest
The conventional planting method of 1-year-old seedling bag seedlings for creating pure forest and supporting the trunks (the method for supporting the trunks recorded in the background art, hereinafter referred to as method one, seedlings) is adopted for the dalbergia odorifera, and the planting effect comparison is carried out by using the planting method of 2-year-old cut-top cutting bag seedlings for creating mixed forest without supporting the trunks (the method of example 3, hereinafter referred to as method two, cutting seedlings), and the results are shown in table 1.
TABLE 1. Symphytum coronarium cuttage seedling and seedling afforestation growth condition
Forestation time: 4 months in 2017
Description of the drawings: the main straight degree of the Pterocarpus heterophyllus is divided into 4 grades: level 1-straight trunk: the number of bent trunk plants accounts for less than 10% of the total number of plants; level 2-the trunk is straight: the number of the main bent plants accounts for 11-20% of the total number of the plants; level 3 — backbone more curved: the number of the main bent plants accounts for 21-30% of the total number of the plants; 4-level-trunk bending: the number of bent trunk strains accounts for more than 31% of the total number of strains.
As can be seen from Table 1, the effect of afforestation of the cutting seedlings is better than that of the seedling seedlings. From the test result of 1 year of growth, the ground diameter and the tree height growth amount of the santalum album linn of the second method are respectively increased by 26.9 percent and 25.3 percent compared with the first method, but the main straight degree of the trunk is reduced by 1 grade, the main reason is that the upright rod of the first method plays a role in early stage, and the second method has short planting time and the associated tree species do not have the trunk supporting effect on the target tree species; from the test results of 5 years, the first method of the ratio of the diameter of the cross toe to the height of the tree of the pteroceltis tatarinowii forest by the second method is respectively increased by 27.1% and 21.2%, and the straight degree of the trunk is improved by 1 grade compared with the first method.
Experimental example 2 comparison of growth of seedlings and cutting seedlings
The method comprises the steps of adopting a traditional planting method (method I, seedling) of planting pure forest by 1-year-old seedling bags and supporting the seedlings with upright columns, and adopting a planting method (method of example 4, method III, cutting seedlings) of constructing the pure forest by cutting the seedlings with top cutting bags for 2 years without supporting the seedlings with upright columns, and carrying out afforestation comparison tests, wherein the results are shown in a table 2.
TABLE 2 growth of cutting and seedling of Dalbergia odorifera in pure forest
Forestation time: 4 months in 2017
Description of the drawings: the main straight degree of the Pterocarpus heterophyllus is divided into 4 grades: level 1-straight trunk: the number of bent trunk plants accounts for less than 10% of the total number of plants; level 2-the trunk is straight: the number of the main bent plants accounts for 11-20% of the total number of the plants; level 3 — backbone more curved: the number of the main stem bending plants accounts for 21-30% of the total number of the plants; level 4-trunk bend: the number of bent trunk strains accounts for more than 31% of the total number of strains.
As can be seen from the table 2, the afforestation test result of 1 year old shows that the growth amount of the cross toe yellow sandalwood ground diameter and the tree height of the afforestation method III is respectively increased by 25 percent and 23.5 percent compared with the method I, but the main trunk straightness is reduced by 1 grade, the main reason is that the method I plays a role in the early stage of the upright rod, and the method III has no upright rod to support the trunk and is easy to bend; from the test results of 5 years of growth, the ground diameter and tree height ratio of the cross toe yellow sandalwood obtained by the first method for three afforestation are respectively increased by 19.4% and 12.3%, and the same grades of the first method and the third method for main stem straightness are 3 grades, which shows that the straight degree of the upright column is better when the top cutting cuttage seedling afforestation is not carried out, and the grade of the upright column for seedling support can be achieved.
Comparing the forestation of the first method, the second method and the third method for 5 years, wherein the trunk straightness: in the second method, cutting and planting seedlings are carried out, and the straightness is improved by 1 grade compared with planting by other methods; growth amount: the second-cut-top cutting seedling has the largest planting growth amount, and the tree stand growth of the third-cut-top cutting seedling is better than that of the third-cut-top cutting seedling. With the increase of the forest age, the trunk supporting tree species for the second afforestation method can play a greater role, and the straightness of the trunk of the target tree species can be continuously improved.
Experimental example 3 cost measurement and calculation of different planting methods
The cost is calculated by three different planting methods of the 5-year-old young forest, and the result is shown in the table 3.
TABLE 3 cost of afforestation in the juvenile period of Dalbergia odorifera
Forestation time:4 month unit in 2017: element/hm 2
As can be seen from Table 3, the costs of forestation in the second and third methods are the same, and the costs of forestation in the second and third methods can be directly saved by 17325 yuan hm -2 Only 65.1% of method one. The method is characterized in that the first method, the second method and the third method for afforestation of the dalbergia odorifera are basically consistent in tending management measures, and the main difference is whether the trunks of the saplings need to be erected and supported. The difference of the costs of the young stage of afforestation mainly lies in the price of the planted nursery stock, the material cost and the labor cost of the vertical bamboo pole, and the investment in other aspects is basically consistent.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
