How many Euodia trees should be planted per mu of land?

SummaryGenerally, about 100-110 Euodia trees are suitable for planting per mu of land. They can be planted in both spring and winter. It is a small-sized tree or shrub, with a basic height of about 3-5 m, and the planting spacing for each plant is about 2-3 m. Euodia has no strict requirements for soil, and can be planted in mountainous areas, hills, sunny slopes, and other places.

I. How many Euodia trees to plant per mu of land

Euodia is a small-sized tree, and the planting quantity is about 100-110 trees per mu. Euodia is a commonly used medicinal herb variety. Its fruit is used as medicine, and it has the effects of warming the middle and dispelling cold, relieving depression and pain, and descending rebellious qi and stopping vomiting. Euodia can be planted in both winter and spring. On prepared land, dig cultivation pits at a spacing of 2 m between plants and rows, with a depth of 50-60 cm and a diameter of 50 cm. Apply farmyard manure into the pits as base fertilizer, then fill the soil level, press it firmly, and water thoroughly to settle the roots.

II. Field management of Euodia

Field management of Euodia is divided into two parts: weeding and fertilizing, and shaping and pruning. In Euodia cultivation, in addition to weeding and fertilizing, the soil should be kept moist after planting.

1. Weeding and fertilizing

Before Euodia sprouts in early spring, apply one topdressing of decomposed dilute human and animal urine to promote the growth of spring shoots. Generally, a two-year-old Euodia tree should be fertilized with about 10 kg of fertilizer per plant, applied in a ring-shaped shallow trench 40 cm away from the roots, and covered with soil after fertilization.

Euodia generally blooms and bears fruit from June to July. From before flowering and fruiting to the Beginning of Autumn, quick-acting nitrogen fertilizer should be applied twice to help the Euodia tree set fruit.

After the fruit is harvested, the orchard should be cleaned promptly, and at the same time, one additional application of farmyard manure and plant ash should be added to build up the soil for overwintering.

2. Shaping and pruning

In the first year, at 80 cm above the ground, select and retain 3-4 robust branches in different directions to cultivate as the first layer of main branches, and let the central main branch grow upward freely.

In the second year, at 60 cm above the first layer of main branches, select and retain 2-3 branches to cultivate as the second layer of main branches.

In the third year, at 50 cm above the second layer of main branches, select and retain 1-2 branches to cultivate as the third layer of main branches. For each layer of main branches, after Euodia defoliates each year or before sprouting in early spring, cut off the terminal buds to promote more branching of branches and leaves and expand the crown, thereby increasing the fruiting area. At the same time, cut off overlapping branches, thin and weak branches, and other branches and leaves on the Euodia tree.

III. Pest and disease control of Euodia

Euodia has relatively few insect pests. If aphids harm branches and leaves and induce diseases, spray 40% dimethoate emulsifiable concentrate at 100 times dilution at the initial stage, once a week for 2-3 weeks. From June to August, when swallowtail butterfly larvae bite young buds and tender leaves, spray with 90% trichlorfon at 800 times dilution to kill them.

IV. Harvest time and processing methods of Euodia

Euodia is generally harvested from August to September. It can be harvested when the fruit is mature and orange in color. At harvest, pick the fruit clusters in strings, dry them in the sun, rub off the fruit stalks after drying, winnow away impurities, and store them in a dry place with ventilation. When harvesting, do not damage the fruiting branches, so as not to affect the yield of Euodia in the following year.
