Cultivation methods and precautions for silver wood
With the rise of urban gardening, silver wood has become a new favorite in courtyards due to its ornamental characteristics of red fruits and golden flowers. This kind of shrub plant, which has both medicinal and ornamental value, often causes growers to fall into misunderstandings during the maintenance process. How to make silver wood grow healthily at home? Let us comprehensively interpret it from basic maintenance to advanced skills. The growth environment of silver wood is regulated, light and moisture scientifically proportioned, silver wood has typical drought-tolerant characteristics, and it is the most prudent to adopt the rule of "dry and irrigate the soil". A watering cycle of 7 - 10 days is maintained in spring and autumn, and the high temperature period in summer is shortened to 5 days and in winter is extended to 15 days. The leaves appear oily and shiny in a full-sun environment. It is recommended to ensure 4 hours of direct light per day for the south-facing balcony, and use it in conjunction with sunshade nets in the western sun environment. The nutrient matrix ratio plan uses garden soil as the base (accounting for 60%), and mixes humus soil (30%) and perlite (10%) to form a breathable structure. It is recommended to mix fermented sheep manure and bone meal at a ratio of 3:1 for base fertilizer. When applying alginic acid water-soluble fertilizer every quarter, it needs to be diluted to 2/3 of the standard concentration to avoid fertilizer damage. Gaberwood shape pruning techniques Seasonal pruning points. The main branches are trimmed two weeks after frost, leaving 3 - 5 main branches distributed in an umbrella-shaped manner. New branches retain 3 - 4 bud points, and a 45-degree incision is maintained when cutting cross branches. The focus of summer pruning is to remove long branches and control the plant height to within 1.8 meters. Cultivation methods and matters needing attention for cuttage propagation and practical operation of silver wood
Select semi-lignified branches, retain 2 - 3 true leaves, and soak the incision in IBA rooting powder solution (concentration 500 ppm) for 30 minutes. Using a cuttage substrate with peat: vermiculite = 1:1, maintaining a ground temperature of 25 ℃ and an air humidity of 80%, new roots can be formed in about 20 days. A biological control system for the prevention and control of silver pests and diseases is constructed to hang yellow sticky insect boards (1 per square meter) during the aphid outbreak period and spray matrine solution (1: 50). For the mulberry thorn moth, Trichogramma (5000 heads per mu) were released during the larvae stage for biological control, and Bacillus thuringiensis suspension (800 times liquid) was sprayed periodically during the adult stage. Environmental warning mechanism After continuous rainy weather, focus on checking the back of leaves, and immediately treat it with mancozeb (600 times liquid) when the initial symptoms of coal pollution disease are found. Spraying Bordeaux mixture (1: 1: 200) before the plum rainy season can effectively prevent leaf spot disease. Family maintenance special reminder that the north-facing closed balcony can be maintained by fill light (filled for 2 - 3 hours a day). It is recommended to set a bird prevention net during the fruit ripening period, which can not only protect the ornamental fruit sequence but also prevent children from eating it accidentally. Root pruning needs to be carried out every two years, removing 1/3 of the old roots and replacing new soil.
Mastering the essence of these maintenance, silver wood can show its best condition in the family environment. From light regulation to pest prevention, every link is related to plant health. Regularly observe growth changes and adjust maintenance strategies in a timely manner, so that this auspicious plant full of gold and jade can always accompany you.
