How do orchids manage water and fertilizer?

Orchids are fresh and refined and are liked by many friends. So how on earth should orchids manage water and fertilizer? Next, I would like to introduce the water and fertilizer management methods of orchids.

(1) Water orchids are not allowed to cultivate too wet soil. In traditional management, orchids should be watered if they are dry and stop if they are wet. There has always been a saying of "dry orchid and wet bamboo". The artificial medium is characterized by good permeability, so when planting with artificial culture medium, no matter how different the particle size is, the actual gap between the basin will be greatly increased, and it is impossible to flood the orchid plant even if strong water management is carried out during the growing period. This has completely changed the traditional saying of "dry orchid and wet bamboo". When watering orchids, master:

1. The matrix is different, the kind is different, the dry and wet is different. For example, Dendrobium and Cartland should be dry, while Phalaenopsis and Phalaenopsis should be wet.

two。 Depending on the season and weather, orchids stop growing because of low temperatures in winter, and should be partial to; in spring, orchids begin to grow because of warmer temperatures, which should be slightly wet, while summer and autumn, with hot weather, large evaporation and orchid growing period, should be watered and fertilized.

3. It varies with each stage of orchid growth, such as the orchid needs more water in the growing period, less in the dormant period and less in the flowering period. Hot days should be carried out in the morning or evening, and in winter at noon. In order to meet the requirements of the environment around the site, it is necessary to create and maintain ventilation around the site. In summer and autumn, clear water is often sprayed to the ground to maintain high air humidity.

(2) the artificial culture medium is used in fertilizer, so the fertilizer efficiency is poor and the fertilizer conservation ability is not good. Therefore, special requirements for fertilizer use technology are put forward, and the methods to be used are as follows:

1. Root application: such as grass retting water, chicken and bird manure and cake fertilizer are diluted and used.

two。 Foliar spraying: such as potassium dihydrogen phosphate 1RU 1000, urine at least 3:10O0, orchid special compound fertilizer 1RU 400. After the orchid leaves the house in spring, the organic fertilizer is applied 2-3 times, and the organic fertilizer is applied 2-3 times in summer and autumn. When the orchid grows grass in spring, the compound fertilizer with high P content can be sprayed several times. The principles to be mastered in fertilization are:

The main results are as follows: (1) the application of fertilizer is different in different growth and development stages. The dormant period and florescence are out of use. During the growing period, more N should be applied, such as grass leaf water, cake fertilizer, urea and so on. Before and after the formation of flower buds, fertilizers such as chicken manure, bone meal and potassium dihydrogen phosphate were sprayed continuously at intervals of 7-10 days.

(2) fertilization varies with different species, such as Magnolia mandshurica should be exempted from N fertilizer, and many wild mountain grass species should not be fertilized more in the stage of introduction and domestication.

(3) the concentration of fertilizer should be low and thin fertilizer should be applied frequently.

The water and fertilizer management of orchids has high and strict requirements on the environment and technology. I hope that friends in need will know more in time before dealing with them.
