2.2 comparative cuttage tests on different substrates

Three different substrates, namely yellow core soil, river sand and light substrate are filled in the plastic seedling raising bag; wherein the volume ratio of the yellow core soil to the river sand is 7: 3; the volume ratio of the husk, the coconut husk, the peat soil and the organic fertilizer in the light matrix is 2:2:5: 1. And 2 sections of the cutting slips are buried in the matrix during cuttage, wherein 1 plant is planted in each bag.

2.3 comparison of seedlings grown in different seedling growing containers

The container is a non-woven fabric light matrix cup, a non-woven fabric bag, a plastic seedling raising bag and a cuttage medium-branch type cutting, the matrix is light matrix, 1 plant is contained in each bag, and 2 sections of the cutting are buried in the matrix during cuttage. Meanwhile, a large pot is used for containing light medium, and similar branches are inserted to breed bare-rooted seedlings.

2.4 comparative test of different numbers of cuttings in light medium cup

The medium-branch type cuttings are inserted into a non-woven light matrix cup and divided into a single plant (inserted into the center), two plants (the cuttings are 1cm away from the cup wall in diameter), and three plants (the cuttings are in an equilateral triangle shape and 1cm away from the cup wall).

2.5 comparative testing of different light matrix materials

3 kinds of light substrates are prepared, and the volume ratio is respectively as follows: (1) 5 parts of rice husk, 2 parts of coconut husk, 2 parts of peat soil and 1 part of organic fertilizer, (2) 3 parts of rice husk, 3 parts of coconut husk, 3 parts of peat soil and 1 part of organic fertilizer, (3) 2 parts of rice husk, 2 parts of coconut husk, 5 parts of peat soil and 1 part of organic fertilizer.

And the data processing adopts DPS v 9.5 standard version software and LSD method multiple comparison.

4 results and analysis

4.1 comparative test for the cuttage of different types of cuttings

The results of comparative cutting tests for different types of cuttings are shown in table 1. When the test is carried out, the roots grow on the branch parts buried in the matrix, a small amount of roots are grown on the nodes, a small amount of roots are grown on the internode epidermis, a large amount of roots grow on the skin part of the section, and the secondary grade of the roots growing on the section part is more. The new branches grow from the sections of the overground part (namely axillary buds), 1-2 new branches grow from one section, the majority of the new branches are 2 new branches, and the growth speeds of the two branches are not greatly different. The cuttings of the tender branch type, the middle branch type and the old branch type have higher rooting survival rate, and the production conditions of the obtained seedlings are similar.

TABLE 1 comparative cuttage test results for different types of cuttings

The letters in the table are indicated as 5% significance level, the same in the table below.

In the test process, the branches with 4 nodes and 5 nodes are cut additionally to carry out trial cuttage, and 2 nodes of the cutting are buried in the substrate during cuttage. As a result, the shoots of the 4 and 5 knots have more axillary buds because the overground part has more new shoots of new buds. However, the cuttings with 5 sections are longer, and the number of cuttings which can be cut by each stock plant can be reduced by 1, which affects the propagation efficiency. Therefore, the number of the cutting is preferably 3-4, more preferably the middle-upper part of the branch.

4.2 comparative cuttage tests on different substrates

The results of comparative cuttings tests on different media are shown in table 2. The three matrixes have higher rooting rate, but the light matrix is more loose and has more sufficient fertility, and the average number of roots and the average ratio of the longest root length plants are more than the worst performance of yellow core soil compared with yellow core soil, river sand and yellow core soil.

TABLE 2 comparative cuttage test results for different media

4.3 comparison of seedlings grown in different seedling growing containers

The results of the comparative tests of different seedling raising containers are shown in table 3, the seedling raising substrates in the tests have the same proportion, and the substrate volumes of the containers are similar. Under the same seedling raising conditions, different seedling raising containers have no obvious difference on seedling raising results. The bolete duffii is a weak herbaceous plant, and in the process of adjusting and transporting the seedlings, because of the protection of the seedling raising container, the survival rate of the container seedlings after long-distance transportation and planting is higher than that of bare-rooted seedlings. The light matrix cup seedlings and the non-woven bag seedlings are lighter and more resistant to extrusion, so that the seedlings are more convenient to frame and transport.

TABLE 3 comparative test results of different seedling raising containers

4.4 comparative test for different numbers of cuttings per container (light medium cup) for growing seedlings

The results of the comparative tests with different numbers of cuttings per container are shown in table 4. When the cuttings reach 3, the purpose of raising the whole seedlings can be achieved, the number of new branches in each container is far larger than 2 and 1, clusters can be formed quickly during planting, and when the number of plants per mu is required to be consistent, the number of planting bags can be reduced, so that the workload is reduced. However, tracking observation shows that cup seedlings of 2 or 3 cuttings need to be outplanted and planted when new branches are 10-15cm long; if the seedlings are planted in time, new branches are too crowded after growing, the seedlings are big and small, and some seedlings are weakened to die, so that the quality and the survival rate of the seedlings are influenced.

TABLE 4 comparative test results for different numbers of cutting plants per cup

4.5 comparative testing of different light matrix materials

The results of comparative tests on different light matrix materials are shown in table 5. In the experiment, the quality performances of the survival rate, the rooting number, the new branch number and the like of each type of seedling are similar under the condition of sufficient water and fertilizer. When the proportion of the chaff in the matrix is large, the matrix has poor water and fertilizer retention capacity, so that better water and fertilizer management is required, such as increasing the water spraying times, keeping the water spraying quantity wet, increasing the additional fertilization of leaf fertilizers to keep the growth speed and the like. The formulation cost is relatively high with a large peat soil ratio, but the management cost can be reduced.

TABLE 5 comparative test results for different light matrix materials

4.6 seedling management

The seedling management is mainly water and fertilizer management, and the guarantee of survival is that enough water is sprayed but no water is accumulated. After the sprouts grow, additional fertilizer is needed, the sprouts which are not subjected to additional fertilizer grow slowly, and the seedlings are easy to yellow; the growth of topdressing is good every week, the leaves are dark green, and the new branches are healthy and strong. The fertilizer is applied between two days every two weeks.

5 conclusion

The cutting propagation is an effective seedling breeding means for the dicliptera chinensis. The old, middle and tender branches of the annual plant have higher rooting rate, and 3-4 sections of each cutting are cut and cut. Rooting 5-7 days after the cutting, wherein the roots are mainly grown at the skin part of the incision. The light medium container is suitable for seedling culture, especially for the non-woven light medium cup, and is more convenient for transportation and preservation in transportation. During cuttage, 1-3 cuttings can be inserted into each container, 3 cuttings are preferably used, later planting and management are more convenient, clumps are formed quickly and are sealed, and planting management cost can be reduced. The light matrix is preferably a material with better water and fertilizer retention. In the seedling management, sufficient water and fertilizer management is a necessary measure for strengthening seedlings and shortening the seedling period, the top dressing is preferably leaf surface water and fertilizer, 0.2% monopotassium phosphate water and fertilizer can be sprayed when new buds grow and develop about 2 weeks, and the water and fertilizer is sprayed once a week until the seedlings are outplanted.
