Comprehensive Newbie Guide to Flower Terminology
Editors answer questions about the introduction of flower care knowledge, comprehensive guide to flower terminology for beginners, please see the detailed introduction below.
I, Water
1, Noun explanation - withholding water
Withholding water is to limit the vegetative growth of flowers by not watering or watering less during the growth process, so that nutrients can accumulate and flower buds can be differentiated. For example, when the new shoots of Bougainvillea, plum blossoms (peach blossoms, chrysanthemums, jasmine, winter coral, bergamot, citrus, etc.) reach about 20 cm in length, they begin to "withhold water", that is, they do not water for 2-3 days, and the top leaves of the plant begin to wilt due to water deficiency, and then a small amount of water is added to restore the leaves. After 2-3 repetitions, the growth of the top branches is inhibited, so that nutrients are concentrated to promote flower bud differentiation.
2, Noun explanation - return water
Return water refers to watering again with clean water the next morning after fertilizing in the evening. It can promote root absorption of fertilizer and prevent fertilizer damage. Because the fertilizer applied the night before penetrates overnight, the concentration of fertilizer is too high, which is not only difficult for roots to absorb but also burns seedlings. After watering "return water", the fertilizer in the soil is diluted, which is beneficial to root absorption. (More suitable for the following flowers: Western (Chinese) azaleas, Clivia, camellias, magnolias, jasmines, pearl orchids, etc.)
3, Noun explanation - waist water
"Waist water" is also called "half water", which means that the soil in the pot is "wet on top and dry at the bottom", that is, the upper half is moist and the lower half is dry. Due to poor soil drainage, the soil in the pot accumulates water, and the water poured cannot leak out of the pot hole.
4, Noun explanation - hard water and soft water
Water is divided into hard water and soft water according to the salt content. Soft water refers to water with a hardness below 8 degrees; hard water refers to water with a hardness above 8 degrees and a higher salt content. Soft water without salt content is preferred for watering.
5, Noun explanation - wet after dry
For some flowers that like moisture, such as azaleas, camellias, gardenias, gardenias, and millet, water should be irrigated according to the principle of "wet after dry", that is, when the surface of the cultivation medium turns white, water should be irrigated until it is moist. It is necessary to keep the pot soil neither too dry nor too wet for a long time and maintain "moisture".
6, Noun explanation - dry and wet thoroughly
For potted flowers that like dryness and fear waterlogging, such as orchids, winter plum, geraniums, etc., water should be irrigated according to the principle of "dry and wet thoroughly". Only when the cultivation medium is dry can water be irrigated. "Irrigate thoroughly" means not to irrigate "waist water", but to make the soil in the pot wet thoroughly from top to bottom. If it is not irrigated thoroughly, the roots will not be able to absorb water, which will affect its growth.
7, Noun explanation - dry rather than wet
For five-needle pines, black pines, and drought-resistant plants, water should be irrigated according to the principle of "dry rather than wet". Only when it is dry enough can water be irrigated, and it must not be waterlogged.
8, Noun explanation - soil moisture
It is usually expressed by the percentage of soil water content. The water needed for the growth of flowers is mainly absorbed from the soil, so the soil moisture is generally about 60-70% of the field capacity.
9, Noun explanation - field capacity
The soil in the field has the maximum water holding capacity, which is called the field capacity, with a value of about 25%, which is the limit value of soil water holding capacity.
10, Noun explanation - air humidity
The size of air humidity is often expressed by the percentage of relative humidity. During the day, the relative humidity is the smallest when the highest temperature occurs in the afternoon, and the largest in the morning.
In general,
