How to take care of and harvest the steering wheel

Currently, in some localities, farmers or farms have known to plant large amounts of lentils because of high economic efficiency. However, how to plant trees to be highly effective is still unknown.

Clove, precious medicine

The Larch (Polyscias fruticosa) belongs to the Five-Family family, with a technique that is not too difficult to plant. This plant is a precious medicinal plant because humans can use all plants from roots, tubers, branches and leaves to make medicine to treat health and spice up dishes such as fish salad, dog meat.

Techniques for growing lentils are not too complicated

Tomb nails are small plants, about 0.8-1.5m high, often grown as ornamental plants in front of houses or pagodas. Tree with double leaves, growing staggered, leaves 3 times sawed feathers, edge of serrated teeth. Small white flowers, grows into a canopy. The fruit is flat, 3-4mm long, about 1mm thick. Clove leaves are dried and cooked with a characteristic aroma, the folk name is called "Chinese medicine" smell. Fresh leaves do not have this fragrance.

Lentils are long-lived plants, prefer moist, light, but also drought-resistant, but not tolerant to flooding . The tree has a wide ecological range, distributed throughout ecological regions, can grow on many soils but it is best to sandy soil. The tree thrives when the temperature is below 25 degrees C (from mid-autumn to late spring).

Classifying the steering wheel

This is the most commonly used species: round-leaf lentils (Polyscias balfouriana Baill), trapezoidal crowns (Silver-edged lentils), big leaf-lentils (Polished nails Polyscias filicifolia (Merr) Baill, disc-shaped studs (Polyscias scutellarius (Burm f) Merr), roasted nails (double leaf double, white gray body, another name is Polyscias serrata Balf).

According to folklore, small leaves have two main types: sticky lentils and spiky nails, techniques for planting this tree are not too difficult.

Sticky stems are small, curly, smooth, large roots, large and soft roots, thick shells for high yield and good quality, this is the type chosen for breeding. Dinh lang is a large leaf-lobed leaf, shaggy bark, light green, small root, less root and hard, thin skin, low productivity. This type of people should not plant.

Prepare to plant

Lentils are drought tolerant plants, which do not like water retention, grow well in sandy soils, porous, with medium moisture. When growing in mass, wide area, people have to plow and cultivate to make soil, up to 20cm high and 50cm wide. If in the hills, growers must pick up holes 20 cm deep, 40cm diameter pits. Lentils are grown by cuttings and can grow all four seasons but preferably in the middle of spring.

The steering wheel offers high economic efficiency

Seasonality : Farmers should plant in the spring, from January to April. In summer, the plants are planted and need to be cutted for 20-25 days to produce new roots for planting. Growers can cuttings by putting cuttings down into the sand pile in the shade, planting distance: 40 x 50 cm or 50x50 cm. Tree density is about 40,000 to 50,000 trees / ha.

Fertilizers and fertilizer techniques

Manuring

Every hectare, people should apply 10 - 15 tons of manure, 400-500 kg of NPK fertilizer, apply all of the fertilizer, avoid fertilizing and seeding.

Dressing

In the first year, in June after planting, the plant should be applied with 8kg of urea / rod by sprinkling it on the cheek and filling it. At the end of the second year, in September after the pruning, the tree should be fertilized with 6 tons / ha and 300 kg of NPK + 100 kg of potassium. In addition, growers need to apply top dressing in the fall, fertilize the fertilizer so that the plants can thrive in the next year

Cultivation techniques

Growers place seed cuttings 50cm apart, set the cuttings in the direction of the bed, between the cuttings lined with manure 4kg / rod and 20kg of NPK fertilizer (avoid removing the homogenous cuttings), then cover, leaving the top cuttings on 5cm ground. When planting is finished, people should cover straw or water hyacinth on the bed surface to keep moisture and humus to make soil loose. If the soil is dry, farmers have to pump flood water 2/3 of the bed or water to ensure soil moisture within 25 days but not to submerge water, if it rains constantly to drain the water right away to avoid rotting.

There are two ways to grow

One is the combination of making scenes and collecting medicinal herbs : People can plant them into holes or straight rows or shapes according to their preferences (rhombus, circle, chiffon ring .)

Planting each hole : Growers dig holes with a diameter of 1m, 35-40cm deep, lining the bottom of the hole with old PE or nylon pieces (so that the roots will gather in the pit, the harvest of the roots will be easily taken away) . After that, people mixed soil with decomposed animal manure (10kg), filled the hole, compressed the soil and planted seedlings, three trees per hole according to the equilateral triangle, 50cm away from the tree. Plants need to be watered and pressed tightly around the soil, the hardworking people create rainbows with drainage ditches around. If so, it is best to keep the hyacinth in the root to keep it moist.

This plant is a precious medicine

Planted in straight lines or in shape : The first step is to grow 40cm wide, 35-40cm deep, old or old nylon plastic lining to the bottom and plant the tree as above (do not put the tree in an equilateral triangle but follow straight row or shape intended to be planted).

The second is planting on a large area : Farmers need to make beds 60cm wide, 35-40cm high, and add holes into two different rows, 50cm away from the tree. The next step is to put down decomposing fertilizer, thin soil, put the seedlings into planting, water and press the soil around the root. If trees are planted on sloping land, growers have to make beds in contour lines to avoid color drift, to prevent rapid drainage after rain.

Care and prevention of pests and diseases

Dinh lang is a year-round growing tree, drought tolerant, less pestilent. Almost no use of pesticides. From the second year on, people need to trim the leaves and branches twice a year in April and September. Each root should only be 1-2 big branches.

Dinh Lang is a year-round growing tree, drought tolerant and less susceptible to pests and diseases. In the first stage of planting, the trees are often gray and cut the cotyledons and eat the stem bark, the stage of strong growth is hardly affected by pests.

All parts of the plant have medicinal uses

In the first stage, growers need to pay attention to prevent from affecting the growth and development of the plant in time. The nurse can take medicine or catch it by hand in the early morning or late afternoon. In addition, people can use some gray pesticides as follows: Single drug TP-Pentin 18EC, Basudin 50EC; Shecpain 36EC, Gottoc 250EC or combine two different drugs: Diptere 80WP + Karate 2.5EC, Sevin 40% + Sherpa 25EC, Ganoi 95SP + Abamectin 36EC, Regent 800WG + Sokupi 0.36AS . or use one of the granular insecticides such as: Basudin 10H, Vibasu 10G, Furadan 3G, Regent 3G . mixing a part of the drug with 10 parts of dry powder powder sprinkled around the stump when transplanting, it has a very good effect of preventing gray insects. .

Collection, processing and preservation

Leaves

When caring, growers need to trim the leaves too thick. When collecting root bark, stem bark, the collector should harvest the leaves first, then choose the cuttings. The leaves are brought to the wind and dried to the best (sound), finally dried to dry.

Root bark, stem bark

Farmers can harvest in the late fall of the second year (5-year crops have the highest yield of stem bark roots). The roots and stems need to be washed off the sandy soil, cut off the big roots, blow off the air for one day to drain (to help peel off easier) to separate each type of stem bark and root bark after peeling. Small roots with a diameter of less than 10mm should not be peeled, the diameter below 5mm should be kept separately. The roots should be dried, dried continuously until crispy.

Classify

Type I is the bark, the root of a tree with diameter (fresh) of 10mm or more. Type II is the stem bark and root bark with a diameter of less than 10mm (the stem bark is nearly 2mm thick). Type III is thin roots and shells less than 2mm.
