Essential nutrients for the growth of orchids

Orchids can grow healthily and healthily in the right environment of sunlight, air, water, temperature and nutrients. While carbon, oxygen and hydrogen in nutrients can be absorbed in air and water, the remaining elements must be provided for orchid absorption in the form of fertilizer.

The nutrients that orchids need most are nitrogen N, phosphorus P and potassium K.

Nitrogen (N) is the main component of amino acids and proteins. Effective absorption can improve the germination rate of orchids and make their leaves beautiful and robust. When the orchid is lack of nitrogen, the leaves will yellowing to a light green, especially the old leaves, and the leaves of the orchid plant become smaller. The number of buds decreased, dwarfing and poor growth appeared. At this time, you can choose Zhiquan, Zhishuo, Zhiyuan, Xishuo and Zhishuo 4fu, or you can choose long-term fertilizer Zhixiang to supplement the nitrogen elements they need.

Phosphorus (P) is the main component of plant somatic nuclear protein. Essential elements that can promote flowering and fruiting, enhance plants and disease resistance. When lacking, the mesophyll becomes thinner, the leaf color is dull, the root growth is poor, the flower bud formation is limited, and the florescence becomes shorter. At this time, you can choose quick-acting fertilizer with high phosphorus and long-term fertilizer.

Potassium (K) helps the synthesis of protein in the body, regulates water absorption and evapotranspiration, enhances the cell vitality of roots, stems and leaves, and increases the cold and heat resistance of orchids. When lacking, the orchid plant weakens and grows slowly; the leaf tip shrinks, the leaf curls, the leaf edge turns brown, the tissue dies, the aging withered; the plant fruit becomes smaller and the seed shrinks. At this time, you can choose to plant Shuohu, plant, plant rich and long-term fertilizer Zhixiang.

In addition, calcium is another indispensable element of orchids, it is the main component of the formation of cell walls; it can neutralize the acidic physique of orchids and maintain normal physiological functions. When the orchid plant is deficient in calcium, it grows slowly, the tip of the new bud often dies, and the leaf tip and leaf margin are necrotic. The young leaves are curving at the tip, sharp and withered. At this time, you can choose to plant strong.
