Caragana breeding method: can Caragana be eaten? the role of flowers? The efficacy and function of Caragana

Maintenance and management

1. Water and fertilizer management

Caragana likes light and is resistant to drought, so it should be placed in a place with plenty of sunshine and smooth air. It is also hardy in winter.

The area south of the Yellow River can overwinter outdoors, and it is best to bury it in the soil with a basin. Watering should master the principle of "no dry, no watering, watering thoroughly", especially during the period, the basin soil should be kept moist and the flowering period can be prolonged. Liquid fertilizer can be applied once in dormant period in winter; liquid fertilizer can be applied once before flowering in spring to prolong flowering period; after flowering, topdressing is applied again to promote the growth of branches and leaves, and a proper amount of thin fertilizer is usually applied.

2. Pruning

After falling leaves in winter, all kinds of branches that affect the shape of the tree can be cut off; after blooming in spring, the branches that have bloomed will be cut short to promote the growth of new branches; in the period of vigorous growth, pruning of long branches can be carried out at any time, and appropriate coring can be carried out to maintain the graceful posture of the tree.

3. Turn the basin

Turn the basin every 2-3 years, the appropriate time is early spring. When turning the basin, we can remove the old soil of 1 stroke 2 or so, replace the fresh cultivated soil, trim the root system, replant, put it in a place of astigmatism, pour water through it, and often spray atomized water to the pile head, and return to normal management after rejuvenation.

Utilization of technology

1. Grazing utilization

Caragana is a high-quality legume forage. Caragana has luxuriant branches and leaves, high grass yield, rich nutrition and strong palatability. it is an excellent forage shrub for livestock. Caragana in a large area can increase forage yield and greatly improve livestock diet quality. Caragana grassland can be used for grazing all the year round, especially in winter and spring and dry years, its feeding value can be improved. When the grass is withered in winter or when the land is covered with snow, livestock eat the young twigs and dead leaves of Caragana Caragana, which is not weak, which is beneficial to pregnant lambs; when the forage grass is green and yellow in early spring, it blossoms in the early stage, and the mother livestock feeds on its twigs, leaves and flowers, which can quickly recover and ensure lambing. When there is a drought in summer, the shallow-rooted forage grasses on the pasture are withered and yellow, and some of them even die, while Caragana Caragana can still grow well with its strong root system and drought resistance, and become a "life-saving grass" for livestock in summer drought.

2. Grass powder or grass granule processing

The coarse old branches of Caragana are crushed and processed into grass powder or grass granules, and sheep and goats are fed in winter and early spring, and the palatability is also good. At present, the utilization of Caragana in our flag is limited to natural feeding of cattle and sheep, and the utilization rate is less than 1%, resulting in the aging or even death of a large number of Caragana branches, resulting in a waste of resources. The branches of Caragana korshinskii were crushed and processed into grass powder or grass particles by manual or mechanical mowing, and supplementary feeding of livestock in winter and early spring can effectively develop and utilize Caragana resources and provide high quality protein feed for animal husbandry production. at the same time, remarkable economic benefits will be obtained.

3. Silage utilization

Caragana silage is one of the best utilization methods. The best utilization period of silage is flowering and vegetative period. the experiment shows that Caragana can be silaged after crushing at flowering stage, opening cellar for 20 days, turquoise color, slightly sour smell, clear structure, PH value 4.6, crude protein 14.59%, crude fat 3.38%, crude fiber 34.41%, crude ash 8.58%, calcium 1.11, phosphorus 0.58%, can be fed, and the cellar opening time is too long. It will reduce the dominant position of lactic acid bacteria, so according to the amount of storage, the quantity should not be too large, and its utilization time can be prolonged at low temperature. You can also add multi-bacterial solid starter bagging or cellar microstorage.

The corn straw and Caragana were crushed at the ratio of 2:1 and evenly mixed, and the cellar was opened for 30 days. The mixed storage color was turquoise, the smell was slightly sour, the structure was clear, the PH value was 3.1,10.02% of crude protein, 3.34% of crude fat, 34.05% of crude fiber, 5.37% of crude ash, 0.60% of calcium and 0.39% of phosphorus. Therefore, the mixed storage of Caragana and corn can improve the palatability of Caragana.

4. Other uses

Caragana has strong adaptability, drought tolerance, barren, not afraid of sand pressure, has a good wind prevention and sand fixation, soil and water conservation, improve the ecological environment. Caragana is a leguminous plant with well-developed root system, which contains a lot of nitrogen and minerals. The root system has many nodules, which can fix nitrogen in the air, increase soil organic matter, and improve soil fertility and structure. The branches and leaves of Caragana are rich in nitrogen, phosphorus, potassium and other elements, which are excellent green manure. In addition, it is also a good nectar plant. The pods and seeds of Caragana are also good fodder. According to analysis, their seeds contain 27.4% crude protein and 31.6% starch. After the seeds are processed and fed to sheep, the fattening effect on sheep is no less than that of soybean. The roots, flowers and seeds of Caragana can be used as medicine, which has the effects of nourishing yin and nourishing blood, menstruation, sedation, relieving itching and so on.

The breeding method of Caragana can be propagated by sowing, cutting, ramet, striping and so on.

It is best to sow seeds along with picking, such as dry storage, soaking seeds to promote germination before sowing in the next spring.

Caragana cuttage can be used for hardwood cuttage from February to March or tender wood cuttage in the rainy season. The cuttings are cut into 8 cm and 12 cm, and the cutting depth is 1 inch 2. Shade is built after cutting, proper watering, shade shed is removed after rooting, light is fully accepted, robust growth is carried out, and the survival rate is high. Ramet propagation is carried out in February and March of spring.

The Culture method of Caragana making Caragana bonsai

Caragana has beautiful branches and leaves, beautiful flowers and colors, such as sparrows and golden flowers, so it is also called broom, which is suitable for bonsai production. Then Xiaoqi shared the breeding methods of Caragana and the production of bonsai.

I. the culture method of Caragana

1. Display: Caragana basin is light-tolerant and drought-resistant, and should be placed in a place with plenty of sunshine and smooth air. Winter is also relatively hardy, the area south of the Yellow River can overwinter outdoors, it is best to be buried in the soil even in the basin.

2. Watering: Caragana basin watering should master the principle of "no dry, no watering, watering thoroughly", especially during the period, the soil should be kept moist and the flowering period can be prolonged.

3. Fertilization: Caragana pot can apply liquid fertilizer once during dormant period in winter; watering liquid fertilizer once before flowering in spring can prolong flowering period; after flowering, apply topdressing again to promote the growth of branches and leaves, usually apply appropriate amount of thin fertilizer.

4. Pruning: after defoliation in winter, Caragana can cut off all kinds of branches that affect the shape of the tree; after flowering in spring, the branches that have bloomed will be cut short to promote the growth of new branches; in the period of vigorous growth, pruning of long branches can be carried out at any time, and appropriate heart-picking can be carried out to maintain the graceful posture of the tree.

5. Turn the basin: Caragana turns the basin every 2-3 years, and the time is suitable for early spring. When turning the basin, we can remove the old soil of 1 stroke 2 or so, replace the fresh cultivated soil, trim the root system, replant, put it in a place of astigmatism, pour water through it, and often spray atomized water to the pile head, and return to normal management after rejuvenation.

Second, Caragana bonsai production

1. Materials: in addition to the cultivation of small seedlings, the piles for bonsai can also be excavated in the mountains for many years, and those with good appearance can be selected to achieve the effect of rapid prototyping. The mining time can be carried out throughout the dormant period and the rainy season. The method of mining is to cut off most of the aboveground stems, then remove the topsoil, find out the growth direction of the main root, and dig patiently and meticulously along the trend of the main root, which is beneficial to the protection of the root system and reduce the damage.

2. Upper basin: Caragana bonsai basin should be a round or square purple sand pottery basin, in order to fully show the roots of Caragana can choose a shallower basin, basin soil to choose neutral or slightly acidic loam or light clay, should not use alkaline soil, ordinary culture soil or pastoral soil can also be used, the basin should be selected in early spring.

3, modeling: for the main branches can be appropriate bending shape, but to pay attention to the effect of each side, not only in the same plane bending; for twigs are mainly pruning, do not cut the same length, in order to appear uneven. When changing soil and basin, the twisted and changeable root system of Caragana should be used to arrange the root system, wrap it around each other, or properly climb it with brown silk to make it show the beauty of the root.

The above is the introduction of Caragana breeding methods and Caragana bonsai production. I hope it will be helpful to everyone and better breed Caragana.

Culture methods of Caragana

Temperature

Caragana is resistant to high temperature and likes light, so we'd better keep it in a place with plenty of sunshine and good air. In the hot summer, it is best to give Caragana proper shade, which can be moved indoors for maintenance. In winter, the outdoor temperature is relatively low, we should put Caragana in a higher temperature indoor for maintenance, and the light is bright, there is sufficient light.

Watering

Daily watering must not be too much watering, to follow the "do not dry do not water, watering thoroughly" principle, if there is stagnant water at the bottom, it is easy to lead to root rot, so we should not only ensure that the basin soil is moist, but also do not water too much. Watering can prolong the florescence of Caragana.

Fertilizer application

Caragana has a great demand for nutrients in its growing season, so we should follow the principle of "thin application of work fertilizer" when applying fertilizer. However, Caragana can also be fertilized properly during winter dormancy, liquid fertilizer can also be applied to blossom in spring, and topdressing can be applied after flowering.

Change the basin

Caragana usually changes the basin every 2-3 years, and the time to change the basin is in spring. When changing the basin, you can remove the old soil and trim the roots, and replant it.
