What nutrients are essential for orchid growth?

In an environment with proper sunlight, air, water, temperature and nutrients,orchidscan grow healthily and vigorously. Among the nutrients, carbon, oxygen and hydrogen can be absorbed from air and water, while the remaining elements must be supplied toorchidsin the form of fertilizer for absorption. orchidsThe nutrients most needed by orchids are nitrogen N, phosphorus P and potassium K. Nitrogen (N) is the main component of amino acids and proteins. Effective absorption can increase theorchid'sgermination rate and make its leaves attractive and sturdy. When orchids lack nitrogen, the leaves turn yellow and become light green, especially the old leaves; the orchid plant's leaves become smaller. The number of shoots decreases; stunting occurs and growth is poor. At this time you can choose Zhiquan, Zhishuo 1#, Zhiyuan, Xishuo and Zhishuo 4#, or you can choose the slow-release fertilizer Zhixiang to supplement the nitrogen they need. Phosphorus (P) is the main component of the nucleoprotein that makes up plant cells. It is an essential element for promoting flowering and fruiting and for strengthening the plant body and disease resistance. When deficient, the leaf mesophyll becomes thin and the leaf color loses its luster; root growth is poor; flower bud formation is restricted and the flowering period becomes shorter. At this time you can choose the high-phosphorus quick-acting fertilizer Zhishuo 2# and the slow-release fertilizer Zhicheng. Potassium (K) helps the synthesis of proteins in the body and regulates water absorption and transpiration, enhances the cell vitality of roots, stems and leaves, and can also increase theorchid'scold resistance and heat resistance. When deficient, the orchid plant becomes weak and growth slows; leaf tips shrink, leaves curl, leaf margins turn brown, tissues die and age and fall off; the plant's fruits become smaller and seeds shrink. At this time you can choose Zhishuo 3#, Zhiben, Zhifu and the slow-release fertilizer Zhixiang. In addition, calcium is another indispensable element for orchids. It is the main component forming the cell wall; it can neutralize the acidic constitution within the orchid plant and maintain normal physiological functions. When the orchid plant lacks calcium, growth is slow, and the tips of new shoots often die; leaf tips and leaf margins become necrotic. The tips of young leaves curl and die at the very tip. At this time you can choose Zhiqiang. Address: Shuiniu Horticulture, Chencun, Shunde, Guangdong
