Breeding method of purse flower
The uniquely shaped purse flower is very popular for its bloated flowers, but many flower lovers often encounter problems such as reproductive failure and plant wilting during the cultivation process. This article will analyze the system from reproduction to maintenance, and teach you hands-on how to cultivate purse flowers. 1. Full strategy for breeding walled-bag flowers 1. Core skills of sowing and reproduction Sowing is the most important breeding method for purse-leaf flowers, and three key nodes need to be accurately controlled: ·Prime time: August to September is the most suitable for sowing in cool climate, and the germination rate reaches 90% when the temperature is stable at 15-18℃·Substrate formula: It is recommended to use the ratio of legus soil: river sand: garden soil =4:3:3, and disinfect with potassium permanganate solution before sowing·Precise sowing process: The sowing amount per square meter is controlled at 0.5g, and the sieve soil covering method is used. The thickness of the soil covering is twice the diameter of the seed. After sowing, the immersion basin method is used to replenish water to maintain the air humidity of more than 70%. The buds can be seen breaking the ground in 7-10 days. 2. Although special techniques for cutting propagation are not commonly used, they are suitable for rare varieties: ·Select semi-lignified top tips, with a length of 8-10cm and 3 leaf nodes·The sand bed needs to be maintained at a constant temperature of 20 ° C, and use ABT rooting powder to treat the incisions·Build a miniature greenhouse, maintain 90% air humidity, and the rooting rate can reach 60% after 15 days. 2. Advanced Guidelines for the Conservation of Purse Flowers 1. Intelligent light and temperature control plan·Light management: receive full sunshine in spring and autumn, use 50% sunshade net in summer, and replenish light for 4 hours/day in winter. Temperature curve: 10-15℃ during the growth period, 13-18℃ during the flowering period, and the temperature difference between day and night is controlled within 5℃ 2. Accurate water and fertilizer supply strategy·Adopt the dual moisturizing method of "see dry and wet + foliar spray" to maintain the substrate moisture content of 30-40%. During the growth period, nitrogen, phosphorus and potassium compound fertilizers (N-P-K=20-20-20) and decomposed soybean cake water·Add potassium dihydrogen phosphate (concentration 0.2%) during the bud appearing period, and cooperate with calcium and magnesium fertilizers to prevent flower bud shedding. 3. The disease prevention system has established three-level protection: ·Substrate pretreatment: high-temperature steam sterilization before sowing·Growth period protection: monthly rotation spraying of mancozeb and azoxystrobin·Environmental control: Keep ventilation>0.5m/s to avoid leaf area water Master these key technical points, it only takes 5 months from sowing to blooming. It is recommended to rotate the flowerpot regularly to ensure that the plant type is symmetrical. Cutting off residual flowers in time after flowering can extend the viewing period by 2-3 weeks. Through scientific maintenance, the purse flowers can continue to bloom for more than 120 days, becoming the most beautiful scenery on the windowsill.
