How to raise goldfish and spider plants before they bloom
Today, Xiaobian will explain to you how to raise goldfish and spider plants before they bloom. Let's take a look!
- - Scientific soil matching is the basis for flowering-Goldfish spider has special requirements for cultivation substrates. It is recommended to use the formula of peat soil: perlite: humus soil =4:3:3. This ratio not only ensures water retention, but also ensures drainage and breathability. New soil should be replaced every spring. The old soil will easily harden after being used for more than one year, resulting in hypoxia in the roots. When replacing soil, pay attention to retaining 1/3 of the protective soil to avoid excessive root damage. Senior flower lovers suggest adding 5% pine scale to the substrate. This organic particle can slowly release nutrients and continuously improve the soil structure.
- - The golden rule of light regulation-sufficient scattered light is needed in spring, autumn and winter, with at least 4 hours of light per day. In summer, 50%-60% of the strong light must be blocked. You can choose a sunshade net or move it to an east-facing balcony. Measured data show that the photosynthesis efficiency of goldfish spider plants is the highest under the illumination of 18,000 - 25,000 lux. It should be noted that sudden changes in light intensity will cause fallen leaves, and adjustment should be gradual. You can judge whether the light is suitable by observing the color of the leaves: the leaf color is dark green to yellow, indicating lack of light, and if the leaf edges are red, the light may be too strong. - - Technical points of precise watering-Adopt the watering principle of "see wet when it is dry", and water it thoroughly immediately when the surface layer 2 cm of soil is dry. The watering frequency is maintained at 3-4 days per time in summer and extended to 7-10 days per time in winter. It is recommended to use a long-spout watering pot to slowly fill water along the edge of the basin until water seeps out from the drainage holes on the bottom of the basin. Monitoring data from professional growers show that maintaining the EC value of the substrate at 0.8- 1.2 mS/cm is most suitable for the growth of goldfish spider plants. Special reminder: Pour off the tray in time after watering, otherwise it may easily cause root rot. - - Temperature and humidity management system-The ideal growth temperature is 18-25℃, and should not be lower than 10℃ in winter. When the temperature exceeds 30 ° C, it is necessary to cool down by spraying to keep the air humidity at 60%-70%. You can place a basin or use a humidifier next to the plant, but be careful to avoid long-term accumulation of water on the leaves. Experiments have proved that maintaining the temperature difference between day and night within the range of 5-8℃ can significantly promote flower bud differentiation. During winter heating in the north, special attention should be paid to stay away from the radiator and often wipe the leaves with clean water to remove dust. - - Critical period of nutrient supply-During the growth period, high-phosphorus and potassium water-soluble fertilizer diluted 1000 times is applied every 15 days from March to October, such as Ruhua Duoduo No. 2. The budding period was changed to once a week, and the concentration was reduced to 1500 times. Stop fertilization in winter to avoid fertilizer damage. Leaf surfaces can be sprayed with 0.1% potassium dihydrogen phosphate solution once a month. Senior growers suggest that mixing slow-release fertilizers such as Austrian green manure 318s can continue to provide nutrients for 3-4 months when mixing soil. Pay attention to watering thoroughly the next day after fertilization to prevent salt accumulation. - - Professional pruning and flower promotion techniques-Re-pruning is carried out in March and September every year to retain 5-6 nodes at the base to stimulate the germination of new branches. Remove dense and weak branches in time to keep the plants ventilated and transparent. Cut off residual flowers immediately after flowers to avoid nutrient consumption. Experimental results show that applying 0.01 mg/L brassinolide after pruning can accelerate the germination of new buds by about 40%. The trimming tools should be disinfected with alcohol, and the incision should be on a 45° slope to reduce the chance of infection. - - Sharing of reproduction tips--Select semi-lignified branches from May to June, cut them into 8-10cm cuttings, and retain the top 2-3 leaves. Use a cuttage substrate with vermiculite: perlite =1:1, keep the temperature at 20-25℃, the humidity above 85%, and generally 15-20 natural roots. In the water plugging method, pay attention to changing the water every 2 days, and add a small amount of activated carbon to prevent rot. Experienced growers have found that treating the base of cuttings with 100ppm NAA solution for 10 seconds can increase the rooting rate to more than 90%. - - Pest and pest control list- -Common diseases include: 1. Root rot: Irrigation roots with 800 times carbendazim solution 2. Leaf spot disease: Mancozeb 500 times liquid spray The main insect pests include: 1. Red spider: 2000 times biphenylhydrazinate solution 2. Aphids: Prevention measures with imidacloprid 1500 times liquid include regular ventilation, avoidance of close planting, and timely removal of diseased leaves. Biological control can release predatory mites to control red spiders, which is safe and pollution-free. - - Special flower promotion skills--1. Control water to promote flowering: The flower bud differentiation period is usually from September to October to properly control water to keep the substrate dry for 2-3 weeks 2. Temperature difference stimulation: Place it on a balcony with a large temperature difference in autumn night for 15-20 days 3. Fill light treatment: Use LED plant lights to fill light for 2 hours every day from 4 to 6 pm in winter. Girdling treatment: Gently girdling old branches over 3 years old. Cultural records of blocking nutrient backflow show that the flowering volume of plants using these measures increased by 58% on average, and the flowering period was extended by 10-15 days. - - Solutions to difficult problems- -Q: What should I do if the leaves turn yellow and fall off? A: Check whether there is too much water and rotten roots, or there is a long-term lack of water. If rotten roots need to be repaired and replaced with soil, if there is no water shortage, soak them in the basin to replenish water. Q: Only leaves grow but not flowers? A: Most of them are due to excessive nitrogen fertilizer or insufficient light, so switch to high-phosphorus potassium fertilizer and increase light. Q: The flower buds fell? A: Usually due to sudden changes in the environment, keep the temperature stable and avoid moving flower pots. Q: Does the blade have a focal edge? A: If the water quality is too strong or caused by fertilizer damage, use rainwater to irrigate and wash the substrate salt. Mastering these core technical points, combined with regular observation and careful management, it is not difficult for the goldfish and spider plants to bloom in large pots. Flower lovers in different regions can appropriately adjust conservation plans according to local climate characteristics. The key is to understand the growth laws of plants and create a suitable microenvironment. Adhering to scientific maintenance will surely harvest the beautiful scenery full of flowers and branches.
