Honeysuckle underwater photography

Honeysuckle has the characteristics of fast growth, long life, developed rhizome, drought resistance, barren resistance and strong cold resistance. Both plain areas and mountainous areas can be planted, and the regulations on soil layers are not tight. Therefore, honeysuckle is widely planted in all provinces of China. The main producing areas are Shandong, Henan, Hunan and other provinces, and the quality produced in Shandong is the best.

The development trend of barren land resources in mountainous areas is honeysuckle production, which can not only obtain obvious economic benefits, but also control soil erosion. Honeysuckle can be dried immediately without production and processing, which belongs to export type. The annual profit of importing and exporting honeysuckle in China reaches tens of millions of dollars.

The breeding techniques of honeysuckle are summarized as follows:

The fruit of honeysuckle. August is perfect ~ 65438+1October, and June harvest165438+1October. After harvesting, the seeds are kneaded in cold water to remove exocarp, chaff and residue, and the round seeds submerged in water are picked up and dried for preservation.

Sand storage method: choose the area with loose soil layer and high and dry terrain, and dig ditches with a depth of 80 cm and a width of 80 cm, depending on the number of seeds. The drainage ditch should be paved with 1 layer 10cm thick wet sand, and 1 straw should be inserted in the middle for ventilation. If there are too many seeds, insert two more straws. Then, the seeds and sand are mixed and stacked in the ditch according to the ratio of 1∶3, and the environmental humidity of the sand is suitable for holding in your hand without water.

When the pile is 20 cm away from the road surface, it will be covered with 1 layer of fine sand, and then a small amount of soil will be paved. Finally, the ditch surface will be sealed with blockboards and bamboo mats. After a period of time, the seeds can be mixed with sand, packed in wooden boxes or bamboo baskets and buried in ditches. Small round holes should be drilled around the wooden case to facilitate ventilation. Check on time during storage to prevent the seeds from becoming moldy. When the seeds are white, you can sow them.

Dry storage method: put the dried seeds into a packaging bag and put them in an ultra-low-temperature, dry and naturally ventilated room. Before sowing in the next spring, soak the seeds in warm water at 30 ~ 50℃ for 24 hours. After fishing, mix with wet sand to promote teeth, and sow when 1/3 seeds turn white. Before sowing, plough and fertilize, and then water.

The suitable row spacing is 65,438+0.5 cm, and the seed dosage of 65,438+0 ~ 65,438+0.5 kg for 65,438+0 mu. After sowing, cover 3cm thick soil or cover 65,438+0.5 cm thick fine sand or sawdust, tamp and germinate for 65,438+00 ~ half a month. Cultivation techniques should be improved when seedlings emerge, and when the height of seedlings reaches 15 cm, the top should be removed to make them sprout branches. At the beginning, the height of seedlings can reach 40 ~ 60 cm, and they can be transplanted and planted in autumn and winter or rainy days in the next year. This method is selected in the specific production and manufacture of cutting seedlings. Cutting can be carried out in the growth and development season of honeysuckle vine (spring, summer and autumn), and it is best to have more rain.

Spring cutting: winter selection 1 ~ 2-year-old rough branch cutting. The specified ear length is 12 ~ 15cm, and there are more than three pairs of axillary buds. After cutting into cuttings, bundle them into 100 ~ 200 cuttings, store them in a wet sand kiln (in the same way as seed storage), and turn the furrow, with the depth of 1 5 ~ 20 cm and the row spacing of 15 ~ 20 cm. Then, the stored cuttings should be taken down and discharged into the furrow, buried in the soil, tamped with water and germinated after 20 days. Proper shading before germination, weeding and fertilization immediately after germination, and proper watering according to drought. When the seedling height is 1.5 ~ 20 cm, the top is removed. At first, the height of seedlings can reach 60 ~ 80 cm. Cutting in summer and autumn: after the first flower harvest (June) or the second flower harvest (July-August), select branches with vigorous growth, cut cuttings with the length of 10 ~ 15 cm, and remove the lower branches, leaving only the upper 1 pair of leaves. Then every 100 cuttings are tied into 1 bundle, and soaked in clear water for 12 hours. If there is no water flow, you can soak the lower half with cold water, and change the fish tank 2-3 times during this period. Just like the planting technology of Poria cocos, it can germinate in half a month after soaking, inserting it into the prepared seedling stage, and then cutting it to shade 50%. When cutting seedlings, pay attention to antifreeze in winter and transplant them in the spring rain next year. Decorative strips can be pre-planted in spring, summer and autumn. The method is to deliberately leave annual branches with tips during maintenance, dig a pit with a depth of 10cm under the branches, then bend the branches into rows and bury them in the soil. If the branches are long and sustainable, the tips of the branches can be exposed on the road. After the roots are regenerated, they are cut off from the pregnant mother for planting.
