Calla lily is an Araceae bulb flower. Its leaves are oval arrow-shaped, bright green. Its pedicels are higher than the leafy clumps, and the succulent inflorescences are hidden in the spathes. The spathes are horseshoe-shaped, white, yellow or pink, elegant and clean, fresh and generous. The potted plants are both flowery and leafy, which is of great ornamental value. After many years of trial and error, the author summarized a set of calla lily integrated management techniques, which are described below. First, with soil pot soil should be fertile, neutral or acidic, can be used fine crushing pond soil (or clay soil) 2 copies, rot leaf soil (or compost) 1, add the appropriate amount of superphosphate and decomposed human and animal feces, Mixed. Second, breeding usually after flowering, stripping the ball around the tuber for one year and bloom in the next year. After the experiment, the author found that the root ramets method can be flowered in the same year. The specific approach is: In late June to early August, combined with the basin, the well-developed large-shaped ramets with roots split by hand (the best Do not use a knife), planted in a prepared pot. If used as cut flowers, two to three ramets may be planted and placed in a cool place after planting. Breeding by this method can be flowered from September to October of that year. Third, management 1, light temperature Calla lily hi warm and humid and slightly shaded environment, but the flowering period to be sunny, otherwise the spathed green, affect the quality. Must ensure that the light every day 3-5 hours, or petiole will extend the impact of ornamental value. Calla lily is not strong in cold, in mid-October to move into the greenhouse. In the summer, it is necessary to spray water to cool and moisturize under shading conditions. 2, watering and fertilizing Calla Lily, moist, fertile soil, that is often referred to as "big fat water", more watering during growth. Fertilizer can be replaced by liquid fertilizers such as cooked soybean cake water and chemical fertilizers (compound fertilizer or diammonium phosphate), and applied once every 2 weeks. When applying liquid fertilizer, avoid pouring fertilizer into the leaf sheath to avoid rot. Someone once mentioned that "see the bud stop fertilizer." After the test comparison, I believe that after seeing buds should increase the amount of fertilizer, so as to ensure that the long flowering period, large and colorful flowers, and buds continue to flower all year round. 3, the use of ferrous sulfate in potted calla lily, top ferrous sulfate is an important part of the author's experiment. Topdressing ferrous sulfate can make Zantedeschia leaves become larger, thicker, greener, smooth and glossy, and the petiole is not easy to extend, thus ensuring the appearance of leaves. At the same time can promote the formation of buds, extending flowering. The specific method is: dilute the ferrous sulfate into a 2% solution, apply it once every one month, and drench it every time. China Agricultural Network Editor
