How to judge whether the cultivation conditions of flowers are suitable or not

In the process of flower cultivation, to judge whether the cultivation conditions of flowers are appropriate, various physical or chemical methods can be used to test. When raising flowers in the family, you can also observe the normal growth and abnormal changes of various organs of flowers by human sensory organs, such as vision, hearing, smell and touch, so as to judge whether the cultivation conditions are appropriate.

The plants with normal root growth have plump apex and long stem nodes; most of the flower pots often extend white roots, indicating that the pot soil is properly mixed. The stem node of light-loving flowers is short and thick, and the leaf color is normal, which is moderate in light; if the stem node is long and stretched, the leaf is shallow, which is large in water, high temperature or insufficient in light. Leaf growth, soil, water, fertilizer, light, temperature, humidity, ventilation and other cultivation conditions, as well as disease and insect damage, the performance of the most obvious. Normal growth of leaves, smooth stretch, thick plump, hand touch bones, finger sound has a solid feeling; abnormal leaves, thin color dim, often showing wilting, yellow, twisted, curly, concave and convex do not stretch. The appearance of flower diseases should be combined with the habits of all kinds of flowers, from which to correctly judge which one or several cultivation conditions are not suitable, and timely measures should be taken. Some flower stems thrive, branches and leaves flourish, but they cannot blossom and bear fruit as scheduled or flowers and fruits are deformed, usually water and fertilizer are too large, resulting in excessive growth; some are related to light, temperature and pruning. Flower drop fruit mostly for water or too dry, but also because of temperature mutation or environmental pollution.

To the judgement of cultivation condition, besides vision, still can judge the wetness and dryness of basin soil from listening to the muffled and crisp sound of knocking basin wall. From the smell of light and light, identify the maturity and fertilizer content of the culture soil, as well as the decomposition degree of various organic fertilizers. The amount of organic matter contained in the soil can be known from the elasticity of the soil felt by fingers. According to the feeling of kneading soil, judge the viscosity, dispersion, softness, board and so on. Depending on the direct feeling of human body, it is effective to adjust the illumination, temperature and air humidity properly in practice.
