What soil is used to cultivate plum blossoms
As the first of the top ten famous flowers in China, the success or failure of plum cultivation is closely related to soil selection. The ancients said that "plum blossoms are beautiful in music, but they are straight and have no appearance; they are sparse and beautiful, but they are dense and have no appearance." Behind this unique aesthetic value is inseparable from the support of scientific and reasonable soil ratio. Mastering the core points of soil for plum cultivation can not only promote the healthy growth of plants, but also allow the plum blossoms blooming in Ling Han to show the best ornamental effect. Four golden rules for plum cultivation soil permeability: the lifeline of root respiration, plum roots require high oxygen. A mixed substrate of legus soil + perlite can be used, and the porosity can reach more than 40%. When turning pots every spring, bamboo sticks can be inserted into the soil to test the air permeability. If the resistance is too large, improved materials such as vermiculite need to be added. Drainage: Protective barrier to prevent root rot. The water seepage rate of the ideal soil should be maintained at 50-100ml per minute, which can be achieved by laying a 3 cm ceramsite layer at the bottom. Special attention should be paid during the rainy season. After 3 consecutive days of rainy weather, check whether the drainage holes on the bottom of the basin are smooth. Persistence of fertility: The energy source of continuous flowering can continuously release phosphorus and potassium for 6-8 months by adding bone meal (5%) and cake fertilizer (10%) to the base fertilizer. In the peak growing season, an additional 500-fold organic liquid fertilizer can increase the number of flowers by 15%-20%. Microbial balance: The key to disease prevention After using high-temperature steam sterilization to treat soil, EM inoculants should be added to restore beneficial flora. Regular irrigation with garlic extract (1:50 ratio) can effectively prevent the occurrence of root rot. The classic formula of professional-grade plum blossom culture soil preparation plan: 3 parts of legus soil +3 parts of vegetable garden soil +2 parts of river sand +2 parts of decomposed sheep manure. The pH value of this formula is stable between 6.0 and 6.5, suitable for most plum blossom varieties. Before use, sieve to remove particles with a diameter of>5 mm. Advanced formula: 4 parts sandy loam soil +2 parts perlite +2 parts peat soil +1 part earthworm manure. The specially added perlite can improve winter insulation performance and keep the roots in-5℃ environment. Vitality.
The knowledge of soil for plum cultivation is essentially an accurate grasp of plant growth needs. From soil permeability to nutrient regulation, every detail affects the growth of plum blossoms. It is suggested that growers replace new soil every 2 years, and continuously optimize the proportion according to plant performance, so as to harvest the beautiful landscape of "sudden fragrance overnight, scattered for thousands of miles of spring" in cold winter season.
