Tea spicy planting method

Tea spicy, also known as Evodia, is a common Chinese herbal medicine, is a bitter stomach tonic and analgesic, but also used as ascaris repellent. Planting can bring good economic benefits, so, what is the tea spicy planting method?

First, what is the spicy planting method?

1. Land selection and preparation

In general, slopes, plains, front and back houses, and roadsides can be planted. 2000-3000 kg of farm manure per mu is applied as base fertilizer, deeply turned and exposed for a few days, and the broken soil is raked flat to form a high border with a width of 1 to 13 meters.

two。 Timely transplanting

Transplanting in winter and spring, transplanting in winter is better (about December). In spring (March to April), the hole is dug according to the plant spacing of 330cm and 400cm, with a diameter of 50cm and 60cm. The depth of the hole depends on the length of the root, first apply rotten barnyard manure or river mud as base fertilizer, and plant seedlings to cover the soil and press. The initial seedlings are small and can be intercropped with peanuts, beans and sweet potatoes.

3. Field management

Timely ploughing and weeding and keeping the soil moist, apply mature human feces and urine once before spring germination, the amount of fertilizer varies with the age of the tree, 10kg of human feces and urine is applied to each tree in three years, and the soil is covered with a ring-shaped shallow trench about 48 cm away from the plant. Before blooming and fruiting in July, apply phosphorus and potassium fertilizer once, apply compost (or river mud, human feces and urine), plant ash and so on in winter to cultivate the soil to prevent freezing.

4. Pruning

The top tip of the main stem was cut off to promote the germination of the young tree with a height of 80cm and 100cm. Among the side branches growing in all directions, three or four strong branches were selected and cultivated into the main branch. In the summer of the second year, three or four fully developed branches were selected between the axils of the main branches, which were cultivated into secondary main branches, and then released lateral branches on the main branches. After several years of shaping and pruning, it has become a high-yielding tree with outer circle and inner space, open crown, ventilation and light, low stem and low crown, which can enter the full fruit period after 3-4 years.

II. Prevention and control of tea spicy diseases and insect pests

1. Coal disease

Also known as coal pollution disease, irregular black-brown coal spots are induced by aphids and scale insects on Evodia rutaecarpa. In the later stage, the leaves and technical stem are covered with thick coal seams, and the diseased trees blossom and bear less fruit.

Aphids and scale insects were sprayed with 2000 × 3000 times diluted 40% dimethoate EC, or 25% imidophos 800 × 1000 times, once every 7 days, 2 times in succession. During the onset of the disease, the patients were sprayed with Bordeaux solution for 10 days, once every 14 days and 3 times in a row.

two。 Rust disease

Rust mainly harms the leaves of Evodia rutaecarpa. At the initial stage of the disease, yellow-green dots and orange blister spots are formed on the leaves, resulting in the death of the leaves.

Spray Baume 0.3 degree stone sulfur mixture or 65% Dyson zinc wettable powder 500 times, once every 7 to 10 days.

3. Old wood worm

The larvae ate in the trunk and died in the hollow of the stem. From July to October, glial secretions, sawdust and insect droppings appeared on the trunk below 30 cm from the ground.

Scrape off eggs and newly hatched insects with a knife. If the larvae are eaten inside the wood, 50 times of wettable BHC powder can be filled outside the wormhole, or 80% dichlorvos solution can be soaked in cotton to plug the wormhole to seal the hole to kill the larvae.

Tea spicy Evodia rutaecarpa is not strict on the soil, as long as it can maintain good air permeability, late management is not difficult, farmers who want to plant can operate according to the above methods.
