Four-word formula for high-temperature smallpox cultivation

Temperature is a very important environmental condition for flower cultivation, which directly controls the growth, development, flowering and fruiting of flowers.

Each flower has a maximum survival temperature, above which it may cause burns or death. At present, it is

During the hot and hot season, the harm of high temperature to flowers and the "four-word tips" for preventing such hazards are introduced as follows:

1. The harm of high temperature. Too high temperature is very disadvantageous to the growth of flowers, when the external temperature is close to the upper limit temperature of flowers, it will lead to poor growth, growth retardation, and even death in a short time. Generally, the ultra-high temperature of more than 45 ℃ can coagulate the proteins in flower cells due to heat, resulting in plant death. High temperature will make the leaves of foliage flowers turn green, shorten the flowering period or worry the petals. Diseases and insect pests are active frequently under high temperature, and their harm to flowers is also aggravated.

two。 Prevention of high temperature. Based on years of practice, the "four-word formula" for preventing high temperature in flowers and trees is briefly described as follows:

One is to "cover", that is, to cover the shade and prevent strong light. High temperature and strong light almost always appear at the same time, so shielding the strong light can effectively reduce the temperature. For flowers that are afraid of both high temperature and strong light, such as hanging bell begonia, cyclamen, orchid, etc., proper shading or maintenance under the shade in summer high temperature season can provide them with a necessary cool environment. If you do not have the conditions to build an Arbor or no shade shed, you can also use the method of moving into indoor shade during the day and outdoor ventilation at night.

The second is "sprinkling", that is, sprinkling water to humidify and cool down. In the middle of summer, spraying water around the site where potted flowers are placed and spraying water on the leaves can not only increase humidity and reduce temperature, but also reduce foliar evaporation, enhance the drought resistance of flowers, and create a cool and humid environment for flowers.

The third is "shelter", that is, shelter from rain and rotting roots. The summer rain is heavy and lasts for a long time, and the sudden drop in temperature caused by rainfall is easy to damage the root hair. The accumulation of water in the basin after rain hinders the respiration of roots, which is easy to cause rotten roots, especially fleshy roots. Therefore, flowers that are weak or semi-dormant in midsummer should be placed in shelter to prevent rotting roots.

The fourth is "communication", that is, ventilation and cooling. The respiration and photosynthesis of flowers must have sufficient fresh air. Poor ventilation will hinder respiration, affect the normal growth of flowers, and even lead to the death of flowers. The planting density of flowers and trees in open field or flower bed should be properly reduced, reasonable shaping and pruning should be carried out to control the overgrowth of some flowers and trees.
