What are the latest precautions for growing Schisandra chinensis?
Schisandra chinensis is a traditional Chinese medicinal herb mainly used for its fruit as medicine. Ancient books record that Schisandra chinensis has the effect of exciting the brain nerves, and many stimulants contain components of Schisandra chinensis. At the same time, it can also treat everyday problems such as colds and coughs, and can also lower blood pressure to a certain extent. Market demand for Schisandra chinensis is very large, so people are needed to grow it. So what do we need to pay attention to when growing Schisandra chinensis? Let Qinnong Web tell you below.
1. Planting time
Special attention must be paid to the planting time of Schisandra chinensis, because the temperature during its growth period cannot be too high, and at the same time the temperature cannot be too low. Therefore, we generally sow and raise seedlings in spring each year, that is, in March or April, and then transplant from early May to mid-May. Of course, there is another transplanting time at the end of September. These two times are very suitable for transplanting Schisandra chinensis. However, sowing must be chosen in spring, otherwise Schisandra chinensis cannot grow normally. Even if seedling raising succeeds at other times, various diseases will appear.
⟦NL>2. Seed treatment
The seeds of Schisandra chinensis are rather unusual, which is to say that they can only germinate in an environment with relatively low temperatures and very little rain, but the temperature of the growing environment cannot be too low. Therefore, when sowing, we soak the seeds in cold water for two to three days, then put them into a basin containing a gibberellin solution and soak them for one day. Finally, remove them and rinse them repeatedly with clean water about three times. Finally, mix them evenly with some wet river sand, wrap them in a wet towel, bury them in the soil, and after about ten days sprouting white will appear, and then they can be sown.
3. Fertilizer and water management
Because Schisandra chinensis has relatively strict requirements for its growing environment, fertilizer and water management, especially water management, requires great attention. Schisandra chinensis is very afraid of drought during its growth period, so we must always keep the soil moist. Secondly, it is also very afraid of waterlogging. Once the rainy season comes, we must drain excess water from the field. Therefore, under normal circumstances, it generally needs watering about every five to seven days. However, during the flowering and fruiting periods of Schisandra chinensis, the demand for water is greater than usual, so it is generally watered once every three to four days. Schisandra chinensis grows relatively slowly, so it needs frequent fertilization, that is, frequent light fertilization. The period when it needs the most nutrients during the entire growth period is when it grows leaves. On average, one mu requires ten to twenty kilograms of farmyard manure and five to ten grams of phosphate fertilizer. The second time is during the flowering period, requiring fifteen kilograms of potassium fertilizer and ten kilograms of phosphate fertilizer to promote fruit ripening.
4. Seedling stage management
Seedling stage management mainly requires attention to three aspects: trellising, pruning branches and leaves, and weeding. In the second year after transplanting, the seedlings of Schisandra chinensis will grow relatively quickly. Therefore, in order to maintain the most reasonable density, we generally set up a support beside each Schisandra chinensis plant, then tie it with rope and let it climb along the rope. As for pruning branches and leaves, it is actually also for field density and increasing yield, so we do it every spring and autumn. Generally, some old, weak, diseased, and pest-damaged branches and leaves are cut off so that it can grow new branches. Finally, in order to maintain soil permeability, we regularly carry out intertillage and weeding.
5. Disease control
Schisandra chinensis generally has few diseases, at most leaf blight or a small number of leaf roller insects. For leaf blight, we can usually prevent it by pruning branches and leaves. In the early stage of the disease, Bordeaux solution can be used for spraying, three to four times in a row. For leaf roller insects, we can only use trichlorfon solution or dimethoate emulsion solution for spraying, but we must pay attention that no pesticide can be sprayed half a month before fruit harvest.
