Introduction to beginners-watering

one. Term explanation-buckling water is in the process of flower growth, no watering or less watering to limit its vegetative growth, so that nutrients are accumulated, which is conducive to flower bud differentiation and formation of flower buds. For example, the cultivation of triangular plum, plum blossom (green peach, chrysanthemum, jasmine, winter coral, bergamot, orange, etc.) begins to "buckle water" when the new shoot grows to about 20 cm, that is, without watering for 2-3 days, the plant begins to show a withered state due to lack of water, and only a small amount of water is watered to restore the leaves. After repeated 2-3 times, the growth of the top of the branch is inhibited, making nutrients concentrated and promoting flower bud differentiation.

2. Noun explanation-backwater means that fresh water must be watered again in the morning after fertilizing the night before. It can promote the root system to absorb fertilizer and avoid fertilizer damage. Because the fertilizer applied the night before last after a night of infiltration, the concentration of fertilizer is too high, not only it is not easy to absorb the roots, but also burn the seedlings. After watering "backwater", the fertilizer in the soil is diluted, which is beneficial to root absorption. (more suitable for the following flowers: Cuckoo, Gentleman, Camellia, Magnolia, Jasmine, Magnolia, Michelia, etc.)

3. Noun explanation-"blocking waist water" is also called "half-cut water", which means that the basin soil is "wet on top and dry on bottom", that is, the upper part is wet and the lower part is dry. Due to the poor drainage of the soil leads to stagnant water in the basin soil, the poured water can not leak out of the basin hole.

4. Noun explanation-hard water and soft water are divided into hard water and soft water according to the condition of salt content. Soft water refers to water whose hardness is less than 8 degrees; hard water refers to water whose hardness is higher than 8 degrees and has higher salt content. Water should be watered with salt-free soft water.

5, noun explanation-see dry see wet for some flowers that like to be wet, such as rhododendron, camellia, Michelia, gardenia, Milan, etc., it is necessary to water according to the principle of "dry and wet". When you see the white surface of the cultivation medium, you can water it until it is wet. To achieve the basin soil should not be too dry or too wet for a long time, just keep it "moist".

6. Noun explanation-dry and thoroughly watered potted flowers such as orchids, preserved plums and geraniums that like dry and afraid of waterlogging should be watered according to the principle of "dry and thoroughly watered". Only when the cultivation medium is dry can it be watered. "watering thoroughly" means not pouring "waist water", but to make the basin soil drenched thoroughly. If it is not irrigated thoroughly, the root system will not be able to absorb water, which will affect its growth.

7. Noun explanation-better dry than wet for five-needle pine, black pine and xerophytes, water should be watered according to the principle of "better dry than wet". Water must not be accumulated until it is thoroughly dry.

8. Noun explanation-soil moisture is usually expressed as a percentage of soil water content. The water needed for flower growth is mainly absorbed from the soil, so the soil moisture is generally 60-70% of the field capacity.

9. Noun explanation-the field soil has a maximum water-holding capacity, which is collectively referred to as the field water-holding capacity, which is about 25%, which is a limit of soil water-holding capacity.

10. Noun explanation-the magnitude of air humidity is often expressed as a percentage of air relative humidity. During the day, at the highest temperature in the afternoon, the relative humidity of the air is the smallest and the maximum in the morning. The air humidity required for general flowers is about 65-70%, while plants in arid and desert climates are much lower than this. Species with aerial roots, such as greenhouse flowers, tropical foliage plants and tropical orchids, as well as humidity-loving plants such as ferns, need about 70-80% air humidity.

11. Noun explanation-- dry air: due to dry air, a large amount of water in flowers transpirates. At this time, the lack of water in the soil will cause the plant water imbalance and temporarily wither, but it will not die.

12. Noun explanation-soil drought: atmospheric drought often causes soil drought. Soil long-term expenditure of water, and there is no timely replenishment, can not supply the water needed by flowers, resulting in withering and death.

13, noun explanation-waterlogging due to poor soil drainage, too much water, air can not enter the soil, over time will cause plant suffocation and death.
