Goji berry, scientifically known as *Lycium barbarum*, is a small deciduous shrub belonging to the Solanaceae family. It is also commonly referred to as "scorpion fruit" or "dog's root." This plant is well-known for its nutritious and medicinal fruits, which have been used in traditional Chinese medicine for centuries. The flowering period typically occurs between June and September, with fruiting taking place from September to October. All parts of the plant—leaves, roots, and fruits—can be used medicinally. Additionally, when the roots become old, they can be cultivated into ornamental root bonsai.
Goji plants are highly adaptable, tolerating drought, poor soil, salinity, and even desert-like conditions. However, they thrive best in well-drained, sandy loam soil with good air circulation. Cultivation techniques include:
First, propagation is most commonly done through cuttings. The process involves preparing the nursery bed by deeply tilling the soil and adding 1,500 to 2,000 kilograms of organic fertilizer per acre, or 100 kilograms of chemical fertilizer. Cuttings are collected in spring before pruning large seedlings, and each cutting is cut to a length of 10 to 15 cm. After soaking in rooting powder for 24 hours, the cuttings are planted in rows spaced 30 cm apart, with 5 cm between each cutting, inserted 5 to 10 cm deep into the soil.
Second, when transplanting seedlings into the garden, trenches are dug at a spacing of 1 meter by 33 cm, with a depth of 30 to 40 cm. Each acre is fertilized with 2,000 kg of base fertilizer, allowing for approximately 2,000 plants per acre.
Third, field management includes regular weeding to prevent competition from weeds, which can hinder growth and increase the risk of pests and diseases. Fertilization should be applied during the growing season, especially during sprouting, flowering, and fruiting stages. Typically, two to three applications are made to promote healthy growth, strong stems, and increased fruit production.
Pruning is essential for maintaining plant health. Goji has strong branching ability, so it’s important to remove old branches before spring budding, cut back excessive branches in summer, and prune diseased or old branches in autumn. This helps reduce disease incidence, improve air circulation, and conserve nutrients. Newly planted seedlings should be topped when the main stem reaches 60 cm, leaving 3 to 5 side branches. In the second year, selected lateral branches are pruned back to 30 cm to form the first layer of the canopy. Over time, this training creates a multi-tiered canopy that increases fruit yield. For bonsai cultivation, soft branches can be trimmed in early spring before the second growth period to encourage blooming the following year.
Moisture management is crucial. While goji plants do not require high humidity, overly dry conditions can negatively affect growth. Proper drainage and irrigation should be maintained based on local weather and soil conditions.
Disease control is an important aspect of goji cultivation. Common diseases include black fruit rot and root rot, often occurring during rainy seasons. Black fruit disease causes buds, flowers, and fruits to turn black, with visible red mucus in wet conditions. Early treatment involves spraying Bordeaux mixture (1:1:200) or 50% carbendazim diluted 1,000 times. Root rot causes blackened, rotted stems and yellowing leaves, leading to plant death. Infected plants must be removed immediately, and the surrounding soil should be disinfected using lime or 70% pentachloronitrobenzene. At the onset of root rot, applying 50% carbendazim at 1,000–1,500 times dilution can help prevent further spread.
With proper care and attention, goji plants can thrive and produce high-quality fruits, making them a valuable addition to both gardens and commercial farms.
ECG Machine
The ECG machine can be divided into single channel and multi-channels (e.g., three, six, and twelve) according to a recorded signal derivative.For 1 Channel ECG, there is only one way to channel the ECG signal, and the waveform of each guide should be recorded one by one. That is, it does not reflect the changes in the conductors at the same time. There are many channels for the large channel of the multi-channel electrocardiogram machine, such as the six-way electrocardiogram machine, which has a six-way amplifier, which can reflect the simultaneous changes of the electrocardiogram of the six conductors at a certain time.
Whether you need a mobile, 3-channel ECG machine, 6-channel ECG machine, 12-channel PC ECG, you will find the proper ECG monitor for your needs in this category.
The compatible ECG electrodes, ECG paper and Ultrasound gel also can be found in this category.
