Longliu planting technology and dried flower production process

Longliu is a deciduous tree or shrub of the genus Salix, which is naturally bent and dried. The dried flower art produced by the Shuyang Dried Flower Company is exported to Europe, America, Japan and South Korea, and earns a lot of foreign exchange.

First, planting technology

1, planting time

The average day-night temperatures in spring are suitable at 10°C, while those in Liyang region are generally from late March to mid-April.

2, site conditions

Long Liu is strong in adaptability, hi light, but also shade-tolerant, alkali-resistant, cold-resistant, water-resistant, can also grow in places with high dryness; strict requirements for the soil, but the best choice for the soil is deep, loose, fertile, sunny, irrigation Well-ventilated plots.

3, planting technology

Longliu sprouts are strong, and they are often planted using cuttings. 1 Site preparation: The plots were roughly leveled, and they were planted about 30 centimeters deep; they had enough base fertilizer to apply fertilizers ranging from 1,000 to 1,500 kilograms per acre. 2 Planting Density: In order to ensure the current year's income and subsequent high yield and stable production, the plant spacing can be selected from 15 to 2050 cm, and about 8,000 plants can be planted per acre. 3 Planting techniques: Select stems about 1 cm thick, robust, full of shoots, no pests and diseases, cut into 20 to 25 cm long branches, vertical cuttings, the upper end exposed 5 cm above the ground. Cut with the scissors. The species are generally harvested before the spring cuttings, and can also be harvested in the winter to be preserved in the winter and reused in the spring of the year.

4, tending management

Longliu is a perennial plant that can be harvested continuously for 6 to 7 years. Therefore, in order to obtain high yields year after year, it is necessary to strengthen tending management. 1 Irrigation and Drainage: Immediately after the cutting of Longliu, water should be poured once to facilitate the growth and growth of the species. During the growing season, we can keep the soil moist, and non-big droughts and floods generally do not require irrigation and drainage. 2 weeding and weeding. It can both remove weeds and cut off the soil capillary, keeping the soil moisture. 3 choose to stay in kind. In the year, 1-2 sticks of strong slivers were kept for each strain in the cutting wicker, and the remaining ones were removed. After that, 2 or 3 roots per plant per year were maintained. 4 top dressing promotion. At the beginning of April and the end of August, top-dressing quick-release fertilizers such as ammonium bicarbonate and urea can also be applied before the rain to prevent the yellowing of the wicker crops. Generally, about 20 kilograms of urea are applied.

5, harvest classification

When the wicker grows to 1.5 to 2 meters high, that is, before mid-August, the first harvest is carried out. The main branch of the wicker is cut off with a knife and then the weeding, irrigation and fertilization are performed in accordance with the requirements of the management of the field. Spraying, leaving the article, the second harvest in mid-November. It can also be harvested in time when prices are high based on market conditions. The cut wickers are graded in bundles of 0.6 to 1 meter, 1 to 1.5 meters, and 1.5 meters or more.

6. Pest control

After germination in the wicker, spray a broad-spectrum, long-acting insecticide such as cypermethrin, insecticidal double, etc. to keep the wicker buds free of pests. The pests and control methods in the growing season are as follows:

1, rust: the main damage to the leaves, severe leaf loss, occurred before and after the equinox. Before the onset of the disease, it can spray 240-360 times Bordeaux mixture. The pathogenic phase can be sprayed with 200 times more rust sodium, or 50% carbendazim 500 times, once every 10 days, and sprayed 2 or 3 times continuously.

2. Scarab: The longevity willow leaves will occur mainly before and after the rain and the beginning of summer. The use of chafer's suspended animation, sooner or later use the shake-off method to kill adult; can also be sprayed 50% kill pine oil 1000 times, or 50% phoxim emulsion 1500 to 2000 times liquid, or trichlorfon 800 to 1000 times liquid Prevention.

3, small weevil: The main harm to the wicker tender, bite off the twig, a serious impact on the quality of wicker. Can spray 400 to 500 times of carbaryl solution, 80% of dichlorvos 500 to 1500 times or 25% of fruit phosphorus 1,000 to 2000 times, once every 7 days, continuous spray 3 times, rain spray, better control effect .

Second, dried flowers production process

1. Peel the skin of dragon willow branches. There are three methods, one is freshly harvested fresh wicker directly hand peeling. This method is more laborious and suitable for small batch processing. The second is to put the bales into the river and press it into the water with a heavy object. After half-month skin rotting, remove and peel off. The third is to use a thick plastic film to seal or place in the room, pass high-temperature steam cooking for a period of time after peeling. This method is simple and convenient, suitable for large-scale processing, but the need to purchase equipment such as boilers, higher costs.

2. After the bleached wicker is peeled off, it is placed in a bleaching tank for bleaching. Bleach is a chemical such as hydrogen peroxide or 84 disinfectant.

3, dyeing According to customer requirements and their own creative ideas, the wicker dyed into a suitable color, can also be tape wrapped around other methods, in the wicker on the pattern or different colors, to become a natural stem.

4. Drying The bleached or dyed wicker is dried according to production requirements. The first is the use of sunlight to dry naturally. The second is stacking on the shelves and drying in a dry room.

5, leaves from the meat will Magnolia, clove and other leaves into the meat remover to remove the outer layer of green leaf, leaving only the mesh veins. (Leaf clarifier chemical formula is a technical patent, this is omitted)

6, dried flower production will be reticular veins dyed into the desired color, made into the shape of petals or leaves, affixed to the bleached or stained dried branches, it became dried flowers art. If you add a lantern in the petals, insert a certain container, the effect is better, and the price is higher.

7. Environmental protection measures In accordance with the requirements of environmental protection, chemical agents such as bleaching, dyeing and desorption shall be treated in a harmless manner and then discharged to prevent and control environmental pollution.
