Planting cost of Dendrobium candidum

Dendrobium candidum has the functions of nourishing intestines and stomach, clearing lungs, moisturizing the skin and, most importantly, improving human immunity. Cultivation is mainly carried out in the greenhouse. The construction of the greenhouse requires ventilation, shade and rain protection, and insect-proof nets. According to the growth habits of Dendrobium candidum, considering the natural factors such as light, temperature, humidity, ventilation and so on, let's take a look at the planting cost of Dendrobium candidum.

Planting environment of Dendrobium candidum

The growth temperature is between 8 and 32 ℃, and the growth period is about 25 ℃. In the high temperature season, it can reach about 32 ℃ under good ventilation conditions, but the time should not be too long. The winter requirement is more than 8 ℃, and the frost-free period is more than 250 Murray 300 days. Dendrobium candidum needs high air humidity for growth and development, but it is not resistant to flooding, so the root system will rot if the water content in the rhizosphere is too heavy. Generally, the water content around the rhizosphere should be about 30%. The cultivation of Dendrobium candidum should be well ventilated. Poor ventilation may lead to thin stems and serious diseases and insect pests. The selection of places with good ambient air quality, no ore production and good ventilation plays an extremely important role in the growth and development of Dendrobium candidum. The cultivation of Dendrobium candidum must meet the five factors of "warmth", "moisture", "ventilation", "ventilation" and "filtration" in order to adapt to the planting environment of Dendrobium candidum.

Planting cycle of Dendrobium candidum

Although Dendrobium candidum is perennial, like other Orchidaceae plants, vegetative growth is completed in a growing season (within one year), that is to say, the accumulation of its active components can be completed in one year. In some areas, such as Xishuangbanna in Yunnan, eastern Guangdong and other places, due to the high temperature in autumn and warm winter, there are autumn buds sprouting, these autumn buds will grow in the next year, and usually end vegetative growth from October to November next year. In short, vegetative growth is a growing season.

New buds will sprout again from February to June next year, and at the same time blossom and bear fruit, that is, reproduction and growth, and the fruit will mature from October to December. At this point, the plant has entered a period of death. Therefore, in theory, Dendrobium candidum can be planted for one year to harvest the finished product. However, due to the differences in planting level and the quality of tissue culture seedlings, in some places, one year's growth can not form a yield, but only plays a role in providing nutrition for the small buds to germinate in the coming year, so it is necessary to go through two or more growing seasons in order to form a certain yield.

Planting cost of Dendrobium candidum

1. Greenhouse construction: steel frame greenhouse construction requires materials: galvanized 50 tubes are 6 meters long and 15 centimeters thick. Greenhouse without dripping film, manual film winder, sunshade net and other greenhouse construction accessories, man-hour fees, etc., the total construction price is 40 yuan per mu, a total of 26640 yuan.

2, nursery bed construction: angle steel construction, including: 3X3 angle iron, 2% thickness, geotechnical barrier net, sunshade net, man-hour total 20 yuan per square meter, a total of 13320 yuan per mu.

3. Tissue culture seedling planting: the average number of seedlings in a bottle is 20, and now the price is 3 yuan per bottle. The row spacing of planting plants is calculated according to 10cm × 10cm, planting standard 3 species and 1 cluster, each square species, the effective seedling bed area per mu is 450sq., a total of 135000 seedlings are planted per mu, a total of 6750 bottles of seedlings are needed, each bottle is calculated at the current price of 3 yuan, a total of 20250 yuan per mu of bottle seedlings.

4. Sprinkler irrigation equipment: according to the calculation of high quality requirements, 8 yuan per square meter, a total of 5328 yuan per mu.

5. Sawdust: sawdust is needed in 360 bags per mu. Now the market price is 12 yuan per bag, a total of 4320 yuan per mu.

6. The details such as disinfectant, water and electricity cost and land rent required for planting (because of different locations, the price varies greatly and is not included in the budget) and other details are not calculated.

Total: planting Dendrobium candidum per mu requires 26640 yuan for greenhouse construction + 13320 yuan for seedling bed construction + 20250 yuan for tissue culture seedlings + 5328 yuan for sprinkler irrigation facilities + 4320 yuan for sawdust = 69858 yuan. The investment of 70,000 per mu of land can be harvested for six to seven years, 200kg in the second year, and 400kg in the third to fifth year. After the sixth year, the annual output begins to decline, and the current purchase price is about 300 per kilogram.
