Overview of several factors that control seed germination

Seed germination is the initial state of the plant. Plants select high-quality seeds and then provide suitable environmental factors such as temperature, humidity, and light, and then the seeds begin to germinate and then grow. Only by guaranteeing the seed germination rate can the plant grow better and more effectively. It is precisely because the seeds play a very important role in the process of plant growth. Therefore, attention has been paid to the quality evaluation of seeds and seed germination tests in recent years. This article mainly analyzes several factors that affect seed germination.

Seed germination requires proper moisture, temperature, light intensity, etc. Only when each condition is met can the seeds germinate successfully. Seed germination is the first step in plant growth. Only a good germination rate can ensure a higher crop yield. The uncontrollability of the natural environment also limits the germination of seeds. In this case, the precision seed germination box has played an enormous role. The seed germination rate box can provide suitable temperature, humidity, and illuminance. In addition, the illumination time can also be adjusted, that is, the precision seed germination box can well simulate the environmental conditions of the plant growth. The precise seed germination box is designed to adapt to the germination needs of the seed and has brought great changes to agriculture.

Moisture and aeration: The amount of water added to the germinating bed is determined by the germination bed and seed characteristics. Germination beds must always be moist during germination. And make enough air around the seeds. Especially in the paper roll and sand bed, it should be noted that the paper roll must be properly loosened; when testing with sand bed and soil, the sand or soil covering the seed should not be pressed. Large seeds such as cotton, peanuts and soybeans should pay special attention to ventilation. Temperature: The germination test should be carried out according to the specified temperature. The temperature of the precise seed germination box and germination chamber should be as consistent as possible during germination. The temperature specified in the data is a ceiling, and when there is light, care should be taken not to exceed this limit. In the case of dormant seeds, abrupt changes in temperature should be completed within 1 h or less or the test should be moved to another germination box with a lower temperature. Light: Most species of seed germinate under light or dark conditions, but light is generally used. The light intensity of the light-requiring seed is 750 to 1250 Lx. If the light is germinated under variable temperature conditions, the light should be conducted during a high temperature period of 8 hours. This shows that seed germination has strict requirements on temperature, moisture, air, and illuminance. In the natural environment, we can use the rainfall monitor to measure the amount of rain in the air, thus calculating the amount of soil moisture, and if we use the precision seed germination box, we do not need to use the rainfall recorder and illuminance recorder. Such as recording instruments, so the seed germination box internal factors are manually controlled.
