The right temperature controls the rapid growth of Clover

The growth of plants is greatly influenced by the environment. For example, parameters such as temperature, humidity, and illuminance in the environment will have a certain influence on the growth of trefoil. So how do you control these factors to make them the most suitable for plant growth. The field microclimate automatic observer can solve this problem. The field microclimate automatic observer is a multi-parameter climatic analyzer. It is also called a small-scale meteorological station. It can measure up to 11 parameters at the same time. It is widely used in meteorology, facilities agriculture, forestry, horticulture, animal husbandry, and other fields to realize facility agriculture. Comprehensive ecological information monitoring, automatic control and intelligent management of the environment.

Among them, in this paper we mainly study the influence of temperature on the trifoliate green. Among the temperature control, we need to use the small-scale automatic weather station because the small-scale automatic weather station contains a temperature sensor. The results are as follows: 30~35°C is the most suitable temperature for the growth of Trifolium repens tuber, the average fresh weight increases by 4.4027~5.1493g, while the temperature above 40°C or below 10°C is unfavorable to Trifolium tuberculosis tissue culture. Seedling growth, plant growth is slow, and fresh weight changes little. The SOD enzyme content increased with increasing temperature and reached a maximum at 35°C. This was mainly due to the fact that under temperature stress, the plant would adapt its response to temperature stress by regulating its own defense system, resulting in an increase in SOD enzyme activity at 40°C. The SOD enzyme content above or below 10°C was significantly lower than that of other treatments. This may be due to the fact that the temperature stress has exceeded the tolerance of the Trifolium pallidum body and cannot remove excess active oxygen from the body and the activity of SOD enzyme is decreased. Membrane repair ability is weakened and plants grow slowly.

It is generally believed that there is a close relationship between soluble protein content and the cold resistance of plants. Under stress conditions, the soluble protein content of plants will increase. Because of its strong hydrocolloid properties, it can increase the water holding capacity of cells, thus reducing the possibility that the raw material will be lethal by freezing. In the experiment, low temperature stress at 5~10°C may induce the expression of low temperature-related proteins, and the plants will produce cold-resistant emergency response, which will cause the increase of soluble protein content. The soluble protein content will be the highest at 35°C, which may be related to the increase of growth-related proteins of Trefoil The relevant; 40 °C temperature inhibited the growth of Trifolium repens tube plantlets, soluble protein content decreased, may be blocked with high temperature stress synthesis or degradation, Yang Huageng, etc. on the Phalaenopsis seedlings under high temperature stress test, also found The protein content is decreasing under high temperature stress, which is presumed to be related to the obstruction or degradation of protein synthesis.

The test results showed that when the growth temperature was 30-35°C, the growth of the seedlings was conducive to the growth of the seedlings; when the temperature dropped below 10°C or rose above 40°C, the insulation or cooling measures should be considered.
