Introduction to sparse planting methods and cultivation management techniques of Carpinus sibirica

The small flower is a deciduous shrub of Saxifragaceae, which is distributed in Northeast and North China, as well as in Russia and Korea. Most of them are born on the edge of broad-leaved forest or in bushes. Small flowers are sparse and elegant in color, small but dense, and bloom at the time of less flowers in summer. It is a good material for landscaping. Now the cultivation and management techniques are introduced as follows to provide dinner for readers.

Morphological characteristics and ecological habits

The sparse plant height of small flower is 1 m to 2 m. Bark grayish brown, peeling; branchlets brown, scattered stellate hairs, old branches gray, lobed. Buds ovate-conical, with brown scales, densely stellate hairs. Leaves opposite, petiole 3 mm to 5 mm long; leaf blade ovate, narrowly ovate or Obovate, 3.5 cm to 8 cm long and 2 cm to 5 cm wide. Inflorescences corymbose, 2 cm to 5 cm in diam., pedicels and calyx densely stellate hairy, calyx campanulate, calyx lobes 5, broadly ovate; petals 5, white, rounded-Obovate. Capsule oblate, seeds numerous, minute. The florescence is June and the fruiting period is from August to September.

Small flowers like light, slightly tolerant to shade, strong cold tolerance, drought tolerance, not resistant to stagnant water, lax requirements on the soil, like deep and fertile sandy loam, can also grow normally in light clay, but grow poorly in saline-alkali soil. Strong sprouting ability, resistant to pruning.

Planting methods and Water and Fertilizer Management

Sparse planting should be carried out before late March and mid-November in early spring. Seedlings should be planted with soil balls as far as possible to ensure their survival rate. Base fertilizer should be applied before planting. The base fertilizer can use cow, horse manure or chicken manure that has been rotten and fermented, and the base fertilizer should be fully mixed with the planting soil. When planting, the backfill should be layered and solid, and then irrigated with head water, two water after a week, and three water after a week.

In addition to applying base fertilizer in planting, topdressing should also be applied in cultivation. Generally speaking, the chemical fertilizer with faster effect is suitable for topdressing, and it should be applied according to the principle of less quantity and more times. Urea can be applied in early summer to promote its branches and leaves, and phosphorus and potassium compound fertilizer should be applied in early autumn to promote the Lignification of its new branches. Apply sesame sauce residue or rotten leaf fertilizer in combination with frozen water at the end of autumn. The application method can be either ring application or acupoint application. It is worth mentioning that if the tree grows weakly after transplanting, foliar spraying can be used to promote its growth and improve its growth.

Small flowers like the moist environment, in addition to watering the first three water when planting, it is necessary to keep the soil moist throughout the growing period. Generally speaking, it can be watered once or twice a month in April, May and June. July and August are the periods of abundant precipitation. If it is not too dry, it can not be watered. It can be watered once in September, October and early November. Frozen water was poured in early December. Defrost water was poured in early spring of the following year. The sparse root system of small flower is shallower, although it is more drought-tolerant, but sufficient water can make it flourish, so watering in the growing period can not be ignored.

Pest control

The pests harmful to Tetranychus parvum are cinnabar spider mite and double-spotted whitefly. If cinnabar spider mites occur, 1.8% Efotin EC 3000 times can be sprayed to kill them, and pomegranate mixture can also be sprayed before germination in early spring to eliminate overwintering mites. If double-spotted whitefly occurs, it can be killed by spraying 1000 times of 25% buprofezin wettable particles or 2000 times of imidacloprid wettable particles in its young larvae.

The common disease is coal fouling disease, which often occurs in the period of high temperature and humidity in summer. in cultivation and management, tree pruning should be strengthened to make the plant ventilated and transparent. We should also pay attention to the prevention and control of insect pests in peacetime management. If it happens, it can be sprayed with 1000 times of methyl topiramate wettable granules, and the disease can be effectively controlled by spraying 3 to 4 times in a row.

Reproduction method

The sparse propagation of floret can be carried out by means of sowing, cutting, ramet and so on. Because of its small and bran-shaped seeds, sowing and reproduction are greatly affected by nature, and grow slowly and blossom late. Although ramet has the characteristics of fast growth and high survival rate, the operation is complex and the number is small. Therefore, cuttage propagation is often used in the propagation of floret.

The cutting substrate can be plain sandy soil or coarse river sand, and 0.2% potassium permanganate solution should be sprayed for disinfection before application. In early July, one-and-a-half-lignified branches were selected and cut into cuttings about 12 cm in length, with a flat cut on the upper cut and a horseshoe shape on the lower cut, and a bundle of 20 cuttings, soaked in 500mg / L ABT rooting agent solution for 12 hours, then cuttings were cut with a row spacing of 5cm × 5cm, and then sprayed with water immediately after cutting, then set up a plastic arch shed and a shade net on the arch shed. It is only allowed to see the sun before 8 o'clock in the morning and after 18:00 in the afternoon, and shade the rest of the time. Spray fog on the cuttings twice a day to keep the humidity in the shed not less than 80% for about 15 days. After half a month of rooting, the mixed solution of 0.2% potassium dihydrogen phosphate and 0.5% urea was sprayed every 10 days to fertilize, which was beneficial to cuttings to grow roots and leaves. Cold prevention measures should be taken in winter, and transplanting can be carried out at the end of March of the following year to cultivate large seedlings.

Pruning method

The common plant shape is tufted round head. After the seedlings are planted, the selected main branches are heavily truncated to promote their branching. When pruning in winter, thin and weak branches and roots and tillers sprouting from the rhizome should be removed. For the weak thin and curved branches, the full length of 1x5 can be truncated, only the full flower buds in the branches can be retained, 3 to 4 erect long flower branches with stronger growth and heavier top can be selected for slow release, and the rest of the over-long flower branches can be treated by retraction method; for long branches, they can be truncated to promote more branches, increase flowering branches, and can also be reserved as regeneration branches.

Garden application

Small flowers sparse and elegant, in landscaping can be used as a natural flower hedge, can also be planted in the lawn, forest edge, can also be planted, can also be used to decorate rockery. The flower branches can be used for vase and ornamental.
