Orchid cultivation: talk about the natural cultivation and seedling development of orchids (turn)

I. Light and Temperature Difference

In general, direct sunlight should be allowed under ventilated conditions without shade at temperatures not exceeding 30 ° C (ventilation can prevent grass from becoming stuffy and increase carbon dioxide content for photosynthesis). Glass insulation should be allowed as much as possible to increase photosynthesis efficiency. Above 30 degrees Celsius, shade is used to control temperature and to maintain indoor brightness as much as possible by reflection, etc., also in order to increase photosynthesis. Ventilation at night, increase oxygen content to help respiration, strive to increase temperature difference, reduce respiration consumption energy, to help store organic matter, make orchid strong, obviously can see false bulb increase, grass thick. In the growth period, in the case of not lower than the growth temperature (generally 15,6 degrees Celsius), the greater the temperature difference, the better; if dormant, it is best not lower than 0 degrees Celsius. But as long as the wind, basin soil dry,-5 degrees less than generally will not frostbite.

Traditional cultivation advocates shade cultivation of orchids. In fact, under the condition of ensuring humidity and controlling temperature, orchids can withstand great intensity of light. Looking for orchid growth points in different environments, it takes one month to accumulate plant energy and organic matter storage that others need one and a half months or even two months or longer to achieve. The result will be unexpected.

Yang grass is short, in fact, conducive to flower out of the frame, but management is not careful, easy to coke tip, large clumps of grass is more suitable for yang species.

2. Rational fertilization

Fertilization is necessary to make orchid healthy and beneficial photosynthesis needs to consume a lot of water and nutrients, potted orchids, often watered, nutrient loss. In some areas of Zhejiang Province, alpine humus soil is used, with sufficient fertility and relatively sound elements, so less fertilizer can be applied appropriately. However, some orchid friends use granular plant materials purchased from the market, such as fairy soil and epiphyte stone, which are relatively deficient in fertilizer, so fertilizer application should be increased appropriately. It is very important to apply different fertilizers at different stages according to different plant materials. Bone meal or potassium dihydrogen phosphate application, to promote bud, strong bud effect directly. Many books and experiences can be referred to, but not excessive. Growth period, nitrogen fertilizer should be partial, if you do not want it to flower, mature period is also partial nitrogen fertilizer, the reason is very simple, orchid is a long-leaf plant. According to different plant material formula, root fertilizer and foliar fertilizer should be carried out alternately according to local conditions.

Fertilization attention points: 1, slowly explore the proportion of configuration. Different fertilizer, different cultivation environment and conditions, different varieties, different fertilizer requirements. It is better to be light, not eager to succeed, do not blindly imitate copy, it will backfire;2, soil fertilizer (organic fertilizer) is better than chemical fertilizer. This is the nature of the plant, biological characteristics of the needs and close, is more conducive to soil fertilizer absorption, therefore, when applying fertilizer mixed with the soil fertilizer, the effect is better;3, recommended soil fertilizer: vegetable cake, beans, urine retting fertilizer. 4. The use of foliar fertilizer is conducive to the increase of leaves and the rejuvenation of weak grass, but it will lead to the acceleration of old grass falling.

III. BUTTON WATER TO PROMOTE BUDS

The so-called buckle water is to dry the pot soil in the early stage of orchid germination for 3-5 days, usually 1-2 times. Deduction of water makes orchids in a survival crisis, forcing them to grow and reproduce, so the effect on multiple seedlings is obvious. During the period of water deduction, phosphorus and potassium fertilizer can be applied.

IV. Reasonable seedling division

Too large clumps of grass due to mutual extrusion, not conducive to germination, to appropriate sub-seedlings. Too single is not conducive to strong grass, 3-5 clusters seem to be very suitable. I won't repeat it.

Orchids to sprout more, a simple sentence: strengthen the light, grow strong seedlings, apply phosphorus and potassium, partial application of nitrogen. Warm shed heating, orchids grow into 2-3 generations of grass every year, the benefits are obvious, but also disadvantages appear, grass potential weakened year by year, stress resistance becomes worse, sick grass increased, natural planting properly, a few years down the number of grass will not be less. The author raises orchid shallow experience, offer discussion.
