Breeding method of red-leaf plum flowers
When growing red-leaf plum flowers in the courtyard, many gardeners often encounter problems such as poor plant development and dull flower color. The growth status of this plant, which has both ornamental and ecological values, can often directly reflect the level of conservation. By systematically sorting out the six core maintenance dimensions, we can solve common dilemmas in the cultivation process. It is recommended to use slightly acidic sandy loam with a pH of 5.5-6.8 for the selection of soil substrates for the three elements of basic maintenance, and mix 30% humus soil to enhance water retention. The surface soil is renovated every spring to avoid variety degradation caused by continuous cropping. Alkaline soil can be adjusted by adding sulfur powder to ensure normal root development. The plant grows most vigorously when the average daily temperature is maintained by coordinated management of temperature and light. In winter, the base of the stem is wrapped with double layers of cold-proof cloth. Direct light needs to be guaranteed for 5 hours every day, and a sunshade net should be used to filter strong light at noon in summer to prevent leaf burns. The scientific irrigation plan for collaborative management of water and fertilizer adopts the principle of "seeing dry, seeing wet". Water is poured every three days during the spring germination period, and sprayed in the morning and evening in summer to increase humidity. Setting a drainage layer to prevent water accumulation, and using siphon flower pots can reduce the risk of root rot by 80%. Precision fertilization strategy Apply decomposed sheep manure as base fertilizer in early spring, and increase phosphorus and potassium fertilizers during flower bud differentiation. Adopt the principle of thin fertilizer and frequent application, and replenish amino acid liquid fertilizer diluted 2000 times every month to avoid scorched leaf margins caused by fertilizer damage. Daily maintenance points for pest and disease prevention and control check the back of the leaves every week from April to June. When red spiders are found, they will immediately use matrine spray. Spraying stone sulfur mixture during clearing gardens in winter can prevent more than 70% of diseases. Ecological weeding retains a 5cm mulch layer to maintain moisture, and manually removes malignant weeds. Covering pine scales can inhibit weeds and regulate soil acidity, forming a benign microecological environment.
By building a systematic maintenance system, red-leaf plum flowers can not only show the best viewing state, but also become an important part of the courtyard ecological chain. Only by regularly observing plant responses and flexibly adjusting management plans can this red color remain vibrant throughout the four seasons.
