There are different fertilizers in different patterns of orchids, and the control of diseases and insect pests of edible fungi.

Cymbidium is a tropical and subtropical epiphytic orchid, which is a popular indoor high-grade ornamental flower all over the world. It has large and colorful flowers, strange flower shape, florescence for several months, no soil cultivation, no application of organic fertilizer (just spray chemical fertilizer solution). Clean and hygienic, many varieties (can be divided into 7 categories and a total of more than 500 varieties), suitable for indoor planting, flowers and leaves have high ornamental value. In recent years, the supply market of cultivation and reproduction of Cymbidium has been introduced in various parts of our country, and the prospect of the market is very promising. There are many kinds of orchids and different fertilizers. The fertilization techniques of orchids are introduced as follows:

Aristolochia mandshurica needs less fertilizer, and it can only be fertilized during the growing period. After the new buds germinate in the growing season, thin cake fertilizer can be applied every 3-4 weeks, or a small amount of flower fertilizer can be evenly applied around the basin to make Ye Maohua beautiful. Fertilization should be stopped during dormancy to make it fully dormant.

There are three methods to apply fertilizer to Cymbidium: one is to mix fertilizer in proportion and mix it with plant material for its growth and development, the other is to mix the prepared fertilizer into solution and pour it into plant material step by step. Third, the prepared fertilizer can be made into solid particles or blocks, which can be applied to pot noodles. More fertilizer should be applied in sunny seasons to ensure the vigorous growth of orchid plants, while in dark, cold or rainy weather, fertilization should be reduced or not at all.

Phalaenopsis Phalaenopsis needs less fertilizer, so we should generally grasp the principle of "thin fertilizer, small amount, diligent application". Mainly master the following links: spring and summer is the peak growth period, thin liquid based on nitrogen fertilizer can be applied once a week, autumn and winter is the flower stem growing period, sparse liquid fertilizer based on phosphorus and potassium fertilizer should be applied every 10-14 days. 0.5% calcium superphosphate aqueous solution can also be applied; after budding, fertilizer should be stopped, otherwise it is easy to drop buds early.

Dendrobium Dendrobium likes fertilizer but should apply thin fertilizer and fertilize frequently. The rarefied fertilizer solution with high nitrogen content should be applied at the seedling stage, and the concentration should be 20%, once a week. After the seedling stage, the plant growth is accelerated, and the dilute liquid fertilizer with complete N, P and K nutrients can be applied every 2 weeks, and the concentration should be 20%. Do not splash on the leaves when applying fertilizer.

Cymbidium is the most fertilizer-loving type of orchids. In the peak growth period, thin fertilizer and water (cake fertilizer and water can also be applied) should be applied every two weeks, or solid granular fertilizer should be put into the basin edge substrate in spring and summer to slowly release nutrients for long-term root absorption. In the seedling stage and low temperature season, little or no organic fertilizer should be applied, and the foliar spraying of N, P and K compound fertilizer with the proportion of 7 ∶ 6 ∶ 19 was very good.

Cartland Cartland can make the seedlings grow healthily and the flowers are beautiful only by applying the right amount of fertilizer in time. The methods are as follows: 1. It is appropriate to apply light fertilizer. Its concentration is generally 50%-80% of that of plant fertilizer. The new buds can be fertilized one week after they are unearthed, and the seedlings should adhere to the principle of "small amount and diligent application". two。 During the growing period, extremely thin pancake fertilizer and water can be applied every 10 to 15 days. When fertilizing, you should be careful not to apply it to leaves and buds. You can also evenly put several grains of fermented pancake fertilizer around the basin every month for its absorption. 3. For orchid plants of flowering age, more phosphorus and potassium fertilizer should be applied during flower bud differentiation to raise roots and flowers, improve photosynthesis efficiency and promote leaf tenacity.
