The latest course of cultivation techniques and methods of Vitex mandshurica

The bark of negundo is the dry root bark and bark near the root of Chinese larch pine. It has the function of sterilization and antibacterial. It is also a kind of medicinal material. At present, the main producing areas of negundo bark are Jiangsu, Anhui, Zhejiang, Hunan, Hubei and other places in China. Do you know how the tree grows? How do you plant the bark of the earth wattle? How to manage the field? The following is a small series of content to share with you today is the cultivation technology of soil wattle skin, let's learn together.

1. Land selection and preparation

Vitex negundo has the characteristics of warm, shady, humid, cold tolerance and strong light, so we need to decide according to its growth habits when choosing the planting place of Vitex negundo. Under normal circumstances, we will choose semi-shady, fertile soil, rich humus content, good water conditions, fertilizer and water conservation, good soil permeability, good drainage sandy loam to plant. Soil preparation should be combined with base fertilizer, which is mainly organic fertilizer, and the dosage per mu is generally controlled at about 1,500 kg. Finally, the soil will be fine, the ground level, and then ditch for the ridge, waiting for planting.

2. Reproductive methods

Although the seed propagation method can also be used, the growth and development speed is very slow, so we are basically using the cutting propagation method in the usual planting. Cuttage propagation is generally carried out in the spring or summer of each year, first of all to choose healthy, no pests, good quality of the rootstock or stem; then cut the cuttage stem into five centimeters of small sections, to ensure that each small section with two to three bud points; finally according to the row spacing of fifteen centimeters, plant spacing of two centimeters for cuttage, watering again can be.

3. Transplanting seedlings

After cutting, it usually takes two to three months to grow several new roots. When the seedlings grow to about ten to fifteen centimeters, we can transplant them. When transplanting, it is generally necessary to plant according to reasonable density, so as to ensure the later growth of soil wattle bark. The row spacing should be controlled at 25 to 30 cm and the plant spacing should be controlled at about 20 to 25 cm.

4. Field management

After planting and survival, we should ensure that there are at least three to four times of intertillage and weeding every day. The time of intertillage is generally based on the growth of soil wattle bark, the growth of weeds in the field, the change of soil permeability caused by rain and watering, etc. Topdressing should be done at least two or three times a year. According to the growth period of soil wattle bark, it is generally mainly nitrogen fertilizer, combined with appropriate amount of phosphorus and potassium fertilizer. Then pay attention to moisturizing, irregular watering. There is also a need for moderate light control in the process of growth of soil wattle bark. Scattered light is used for illumination, and the intensity is generally about 20% to 30%. Finally, it is to control diseases and insect pests. Generally, the most important one is leaf spot disease, which can be sprayed with anti-bacteria.

The planting of soil wattle bark is actually very simple, because its adaptability to the environment is still relatively strong, but we also need to pay attention to some problems in the process of planting, so as to ensure that soil wattle bark grows better.
