Temperature and Humidity Affects Damage of Vegetables and Vegetables to Vegetables
The yield of vegetables is largely influenced by vegetable insects. Vegetable insects play a very important role as one of the main pests of cruciferous vegetables. The harm of pests to green vegetables also depends on three factors: pests, crops, and the environment. This article mainly analyzes the influence of temperature and humidity on the insects in the environment. In this research process, we need to use the relevant scientific instruments, such as temperature and humidity recorders, to record the temperature and humidity in the environment at the same time. At that time, the self-reporting thermometer and hygrometer was also a good choice.
We used the temperature and humidity self-recording instrument to control the temperature and humidity in the environment, and then studied the growth and development of cabbage caterpillars under different temperature and humidity. We found that at the same humidity, the duration of development of the cabbage larvae was significantly shortened with increasing temperature; in the same At the temperature, the duration of development also decreases as the humidity increases. The relationship between the developmental duration y(d) of the cabbage larvae larvae and the temperature t (°C) and relative humidity x (%) can be fitted by the following formula: y = 50.866 7-1.289 3t-0.0615x. From the data, we clearly found that the appropriate temperature and humidity have a tremendous impact on the growth of Pieris rapae. Controlling the growth environment of green vegetables, such as the temperature and humidity of greenhouses, will help reduce the damage of cabbage caterpillars to green vegetables.
The change in temperature and humidity has a great influence on the leaf area of ​​cabbage flowering vegetables. This is also verified by the use of a temperature and humidity recorder. At the same humidity, the temperature of the cabbage worm larvae shortens as the temperature increases. The total leaf area gradually decreased. At the same temperature, with the increase of the humidity, on the one hand, the larvae of the cabbage caterpillars slow down due to dehydration on the body surface, and the pressure required to obtain moisture from the food is reduced. By summarizing their relationships and analysis, it was found that the relationship between the total leaf area A (cm2) of the Larvae larvae and the temperature t (°C) and relative humidity x (%) can be expressed by the following formula: A = 76.5737-0.8599t-0.1920x . Since the temperature and humidity changes have a certain relationship with the edible area of ​​cabbage caterpillars, does it also have a relationship with the rate of consumption of cabbage caterpillars? Through the use of a warm and wet optical recorder to verify the discovery of temperature and humidity and the use of speed there is also a certain relationship. The relationship between the feeding rate v (cm2/d) of the cabbage larvae and the temperature t (°C) and the relative humidity x (%) can be fitted by the following equation: v = -0.6065 + 0.1632 t - 0.0024x.
