1, lime Lime makes the tree white and white, and white has a reflective effect, which not only reduces the absorption of solar energy by the plant, but also reduces the temperature difference between day and night, protects the cortex, prevents sunburn and freezing damage, and prevents the beetle and genomic insects. It is harmful to lay eggs on the branches of pests. The quality of the lime is directly related to the quality of the coating agent. The quality of the lime is not good, and the formulated whitening agent is maintained for a short period of time and does not function properly. 2, sterilization, insecticidal ingredients The first is the role of sterilization and insecticidal substances. The bactericidal component of the whitening agent is generally sulfur, copper sulfate, stone sulphur, and the like. Its main acting substances are active sulfur as well as stone sulphur. The free sulfur in the whitening agent or the highly active sulfur element which is freed from the stone sulphur mixture enters the insect body and acts on the respiratory system to inhibit the mitochondrial electron transfer leading to insect death. When the whitening agent enters the cell body, it mainly acts on the electron transfer between cytochrome B and cytochrome C, inhibits the normal redox reaction, thereby inhibiting the activity of the bacteria and further infecting. Second, the whitening agent is alkaline, which can dissolve the waxy and fungal propagules of the epidermis of the insect, so that the agent can enter the target more easily, and the pest can be effectively controlled. Third, the whitening agent can form a film on the body wall of the pest, sealing the valve of the insect, causing the insect to suffocate and die. 3, adjuvant Generally it is salt, animal oil, soy flour or washing powder.

Hydroponics can be used to make the most use of the interior space. The relatively closed environment of a greenhouse has its own unique management requirements, compared with outdoor production. Pests and diseases, and extremes of heat and humidity, have to be controlled, and irrigation is necessary to provide water. Most greenhouses use sprinklers or drip lines. Significant inputs of heat and light may be required, particularly with winter production of warm-weather vegetables.
