Cultivation methods and matters needing attention for Sinophora japonica
Due to its unique golden vein patterns, Sinophora japonica has become a popular leaf-viewing plant in recent years. Although this plant native to the tropical rainforest has exquisite appearance, as long as you master the key points of environmental control, you can cultivate plants in excellent condition at home. Let us start from four key dimensions and comprehensively analyze the practical skills of family care. The mixture of humus soil and soil uses a gold ratio of humus soil: garden soil: river sand =5:3:2 to ensure that the substrate has both water retention and air permeability. 5% pine scales can be added to enhance drainage in spring and autumn, and bamboo charcoal particles can be added to prevent root rot in summer. It is recommended to change the pot soil every 12-16 months, and retain 1/3 of the core soil when changing pots to help slow down seedlings. Water supply cycle regulation The principle of alternating dry-wet irrigation adopts the irrigation strategy of "seeing dry and wet". Water is poured every 48 hours in spring and autumn, and water is replenished every morning in summer. Special attention should be paid to that when the environmental humidity is lower than 60%, it is necessary to coordinate with morning and evening leaf atomization to replenish water, and using standing water at 25-30 ° C can avoid leaf spots. When the semi-dormant period enters in winter, the watering cycle needs to be extended to 5-7 days. Scientific plan for nutrient supply dual-track fertilization system During the growth period (April to September), a special liquid fertilizer for leaf-viewing plants diluted 1200 times is applied every 14 days, combined with organic fertilizer decomposed sheep manure once a month. Adding potassium dihydrogen phosphate (1500 times solution) during the germination period of new leaves can enhance the color development of veins. During the winter fertilizer cessation period, seaweed essence can be watered every 30 days to maintain root activity. The light intensity gradient manages the scattered light environment to create a gauze curtain with adjustable light blocking rate to maintain the light intensity of 15,000 - 25,000 Lux. It is recommended to place it towards the window sill southeast and receive direct morning light for 3-4 hours every day. Use 75% sunshade net protection from 11:00 to 15:00 in summer, and moderate full sunshine can be received in winter. Rotating the flowerpot 180° regularly allows balanced development of plant types.
Through systematic environmental control, the golden thread grass can not only show charming golden lines, but also maintain its strong vitality. It is recommended to cooperate with real-time monitoring by thermohygrometer to stabilize the maintenance environment within the ideal range of 18-28℃ and humidity of 65%-75%. As long as these core points are mastered, even in the dry environment of the north, the golden thread grass can be cultivated in perfect condition.
