Select 3 water hyacinth samples with the same growing trend. Cut away most of the leaves and leaves that are not fully developed in the center. Leave only one well-developed, uniform-sized leaf and 10 fibrous roots in each, and grow them in a plastic basin with white water. Inside. Placed in artificial climate box 250C, humidity 90%, light intensity 12000Ix, lighting time asked 12h / day artificial climate box culture. Control 3 samples, after the same treatment, placed under white conditions.
Using artificial climate boxes to study the growth conditions of water hyacinth under different light and humidity conditions, it was found that strong light and high humidity environment is the suitable condition for the growth of water hyacinth, it can promote the development of new leaves of water hyacinth and delay the death of plants; The results of the overall growth and development conditions in the suitable environment and the time interval between the development of adjacent leaves and some of the growth index traits indicated that the new leaves and rhizomes rapidly developed to 22 days after culture in the artificial climate chamber. The leaves will die gradually in the order of germination.
Artificial climate chamber for studying the growth environment of water hyacinth
Water hyacinth has strong reproductive capacity and grows more vigorously in nutrient-rich water. It often covers large areas of water in the distribution area, blocking river channels, affecting shipping, suffocating other aquatic organisms, hindering drainage and irrigation, and even threatening the surrounding residents and livestock. drinking water. If it is not possible to effectively control the population size of water hyacinth, when the quantity exceeds the allowable range of environmental capacity, it will not only not play the ecological restoration function of water hyacinth, but will bring a series of disasters. Therefore, the growth of the water hyacinth was investigated from the light and humidity environment conditions, and the overall growth and development conditions and the development intervals of adjacent leaves and some growth index traits under suitable growth conditions were investigated to investigate the occurrence of water hyacinths. Laws and prevention provide theoretical basis. The use of an artificial climate box to control the temperature, humidity, and light conditions improves the study's smooth development of favorable environmental conditions.
