Otter flowers

Otter (Sorbus alnifolia), Rosaceae, Calyces. Deciduous trees, tree height up to 20m. This species is a moderately sunny, well-tolerated, cold-tolerant, hi-wet, well-drained soil that is often found in forests, forest margins, or shrubs, where seeds are propagated. Widely distributed. Due to the golden leaves of autumn leaves, bright red fruits, and golden leaves and red fruits, the leeks have a high ornamental value in highway greening and garden greening. In addition, the yellow and white wood sapwood, exposed to the air gradually become red, red-brown heartwood, beautiful color, detailed structure, can be used as furniture; bark can be used as a dye. Therefore, Minamata flower buds have become an important tree species for timber production and urban greening. At present, there is a great demand for seedlings of scolyapses, which is based on the practice of seedling cultivation for many years.

1 Seed collection and processing

1.1 Seed collection

The seeds of Otter sativa are mature in mid-September. The berry should be harvested in time, then the fruit should be crushed and the seeds rinsed with clean water.

1.2 Seed Treatment

First, the seeds were soaked with potassium permanganate for 3 to 5 minutes and then removed. The clean water was rinsed and then mixed in a wooden box with a 1:3 mixture of seed. The temperature inside the box is controlled at 17 to 20°C, the humidity is controlled at 60% to 70%, and it is turned every 3 to 5 days. It can germinate when it is 120 to 150 days. If it is less than 30% of the seeds when it is found in the sowing season, it should be immediately placed under the condition of 1 to 5°C to control germination.

2 Selection and site preparation

According to the biological characteristics of B. edulis, the nursery should be selected for loose texture, good drainage, low groundwater level, deep neutral or slightly acidic soil, and a relatively fertile light loam. Avoid seedlings in heavy soil. Fine preparation and bed preparation before sowing, usually at the end of April as a high bed (bed above the surface of 8 ~ 10cm), bed width 1m, bed length 10 ~ 20m, should extend north and south. Spread the fully cooked farmyard fertilizer and ammonium dihydrogen phosphate to the bed, farmyard fertilizer 5kg/m2, compound fertilizer 40g/m2, turn the bed surface, the depth is 25cm, mix the fertilizer evenly in the soil, break up the soil and block the rough surface . In order to prevent pests and diseases, we should spread quinoline nitrobenzene + zeocin 4g/m2 to the bed surface, and finally make a good bed.

3 Seeding and Seedling Management

After treatment, the mixed sand seeds should be sowed in time. When the average ground temperature reaches 8-9°C, it can be sowed. Sowing time in the Xinbin area is in late April or early May. Bed sowing, first to extend the bed every 5 meters long ditch, and the bottom of the ditch flat, and then sow the ditch evenly, while sowing side compaction, to prevent evaporation of soil moisture, in order to facilitate the protection. The seeding rate was 20g/m2, and finally the soil was covered with 1.0 to 1.5cm in the trenches. Immediately the water was sprayed onto the bed with a soaking depth of 15 to 20cm. From sowing to the seedlings before the Qi, keep the topsoil moist, moisture content of about 60% to prevent the seed buds dry, resulting in lack of seedling broken. At the end of June, due to the delicate stems of seedlings, the temperature difference on the surface was relatively large. To prevent sunburn and pests and diseases, a small amount of watering was required to adjust the temperature and humidity of the bed surface. July-August is generally a period of vigorous growth of seedlings. Sufficient water must be supplied. Every 2 to 3 days, water is poured for 1 time. In addition to the principles of “in addition to early, small, and in addition to”, weeding is often performed. After mid-August, control the watering, unless there is a special drought, usually do not water, reduce the soil temperature. In order to cultivate strong seedlings, fertilize bed seedlings at the beginning of July, apply 15-20 g/m2 compound fertilizer, apply 2 times a year, and then apply fertilization. However, the fertilization time should not be too late, prompting the seedlings to be lignified, which is beneficial to seedlings. Wintering.

4 Pest control

In order to prevent the occurrence of pests and diseases, the seedlings must be sprayed with 500-fold solution of Dixon or 500-fold solution of methyl isothiophos, and sprayed once every 7 days for 3 to 5 times.

5 Seedling density

After many years of experimentation, cultivar cultivars of leeks grow at a seedling density of 110-140 plants/m2, and nursery plants are produced one year later. The seedling height can reach 50 cm and the ground diameter 0.53 cm. In the spring, the water scape buds can be planted as green seedlings or afforested on the mountain.

Electric Over Blanket is similar to Electric Under Blanket, but a bit different.

Electric over blanket is used by covering human body to keep warm.

Normally electric over blanket is not recommended to be used during sleeping, as it might cause overheating, although it has the function of overheating protection.

Normally over blanket shuts off after 2 hours, for the sake of safety.
