Problems solved by technology

[0003] Vetiver's propagation technology has been using traditional tiller propagation and seed propagation technology. Seed propagation technology is termed sexual reproduction, and the possibility of progeny differentiation is very high. It cannot guarantee the excellent characteristics of asexual strains, and the germination rate is less than 10%. The problem of germination rate has not been solved so far
But its existing problem is: this invention belongs to tissue culture, requires aseptic operation, the condition required by this breeding method is relatively high, and its cost is also high, it is difficult to obtain large-scale promotion, still can not meet the needs of the market

Embodiment 1

[0026] Embodiment 1, the method for propagating vetiver seedlings of a kind of sand burying stalk mentioned in the present invention, comprises the following steps:

[0027] 1. Use vetiver stems with a plant height of 50 cm or more, and use the part of the stalks between 2 cm from the rhizome and 30 cm below the tip of the vetiver to cut into 5 cm long segments;

[0028] 2. Use a scalpel to cut the stem section touching the sand surface, and cut about 4-6 pieces for each stem section;

[0029] 3. Put the sand bed in the high-temperature sun for 5 days, and disinfect the sand bed with 500 times carbendazim solution;

[0030] 4. Spray the sand bed to keep the water content of the sand bed at about 70%;

[0031] 5. Soak the stem section in 50mg / L indole acetic acid for 10 minutes;

[0032] 6. Dry the cut stems in the sun for 0.5 days;

[0033] 7. Insert the stem section into the sand bed and bury it half as deep;

[0034] 8. Spray once every two days until calluses are produc...

Embodiment 2

[0045] Embodiment 2, a method for propagating vetiver seedlings with sand-buried stalks mentioned in the present invention comprises the following steps:

[0046] 1. Use vetiver stems with a plant height of 50 cm or more, and use the part of the stalks between 2 cm from the rhizome and 30 cm below the tip of the vetiver to cut into 5 cm long segments;

[0047] 2. Use a scalpel to cut the stem section touching the sand surface, and cut about 4-6 pieces for each stem section;

[0048] 3. Put the sand bed in the high-temperature sun for 5 days, and disinfect the sand bed with 500 times carbendazim solution;

[0049] 4. Spray the sand bed to keep the water content of the sand bed at 70%;

[0050] 5. Soak the stem section in 40mg / L naphthaleneacetic acid for 10 minutes;

[0051] 6. Dry the cut stems in the sun for 0.5 days;

[0052] 7. Insert the stem section into the sand bed and bury it half as deep;

[0053] 8. Spray once every two days until calluses are produced at the inc...

Embodiment 3

[0057] Embodiment 3, a method for propagating vetiver seedlings with sand-buried stalks mentioned in the present invention comprises the following steps:

[0058] 1. Use vetiver stems with a plant height of 50 cm or more, and use the part of the stalks between 2 cm from the rhizome and 30 cm below the tip of the vetiver to cut into 5 cm long segments;

[0059] 2. Use a scalpel to cut the stem section touching the sand surface, and cut about 4-6 pieces for each stem section;

[0060] 3. Put the sand bed in the high-temperature sun for 5 days, and disinfect the sand bed with 500 times carbendazim solution;

[0061] 4. Spray the sand bed to keep the water content of the sand bed at 70%;

[0062] 5. Soak the stem section in 60mg / L indole butyric acid for 10 minutes;

[0063] 6. Dry the cut stems in the sun for 0.5 days;

[0064] 7. Insert the stem section into the sand bed and bury it half as deep;

Abstract

The invention relates to a method for breeding vetiveria zizanioides seedlings by burying stems in sand. The technical scheme includes the following steps: 1, a step of preparing a sand bed; 2, a stepof selecting and preparing stem segments; 3, a step of preparing a soaking solution; 4, a step of burying the stem segments in sand to perform rooting; and 5, a step of transplanting the stem segments. The beneficial effects of the method are that compared with traditional breeding ways, the method has high breeding coefficient which can reach 1 : 25-30, the breeding time is short, 40 days beinga breeding period, seedlings have good quality, and the excellent properties of salt-tolerant strains can be preserved; the traditional breeding ways are carried out in fields, which is restricted byseasons; and the method can be carried out indoors, continuous breeding can be yearly performed by combining with greenhouses, seedling supply for surrounding areas can be realized, costs on transporting seedlings can be saved, seedling survival rates can be enhanced, and the huge gap of market on vetiveria zizanioides seedlings can be rapidly filled up.

Description

technical field [0001] The invention relates to a method for propagating vetiver grass, in particular to a method for propagating vetiver grass seedlings by burying stems in sand. Background technique [0002] Vetiver ( Vetiveria zizanioides ) belongs to the Poaceae Vetiver genus and is a perennial herb. It is a forage grass for herbivores such as poultry, beef cattle, and sheep. It has a high protein content. Because of its well-developed root system and deep underground development, it has been favored by countries all over the world since the 1980s and has become a well-known soil and water conservation plant. and slope fixed plants. Vetiver is mainly used for engineering protection and soil erosion control of farmland, slopes, roads, railways, embankments and industrial and mining sites, and has a purifying effect on heavy metal pollution and eutrophication of water bodies. It can also be used as forage, fuel, cultivation of edible fungi, papermaking and weaving handi...
