Description

Drought tolerance appraisal device of maize seedling stage
Technical Field
The utility model relates to the technical field of agricultural research, in particular to a device for identifying drought tolerance of corn in a seedling stage.
Background
Most of corns in China are planted on dry lands in northeast, northwest, southwest and northwest, and drought often occurs during sowing. Although the corn requires less water from germination to seedling stage (only 3.1-6.1% of the total water demand), it is most sensitive to water during this stage (delrin et al, 1983). Drought stress on corn seedlings can cause seedling growth obstruction, weak bud potential, less rooting amount, short root, weak seedling and low survival rate, and the growth and the final yield of the seed particles are seriously influenced. In recent years, along with the rapid advance of mechanical single-seed sowing technology, the drought resistance of corn in the seedling stage is particularly important. The drought-enduring variety for planting corn in seedling stage is an effective measure for enlarging the arable area of a drought area and ensuring the whole seedling to ensure stable yield or increase yield. The development of drought-tolerant character screening and drought-tolerant evaluation is the key for screening drought-tolerant resources and breeding drought-tolerant varieties. Therefore, the development of drought tolerance identification of the corn seedling stage has extremely important significance.
At present, most widely used penetrant polyethylene glycol (PEG)6000 is adopted for drought tolerance identification of corn seeds in the germination stage. However, due to the large difference of the osmotic pressure suitable for drought simulation and different time of stress treatment, the field production cannot be simulated really, the accuracy and the reproducibility of the identification result are extremely poor and far from the actual field condition, the drought degree cannot be adjusted by the existing test device, the variable research is carried out on the drought degree, and the drought tolerance degree is inconvenient to test, so the drought tolerance identification test device for the corn seedling stage is needed to solve the problems. In addition to the fact that the growth of economic crops is seriously affected due to the fact that the drought condition frequently occurs in the years because of climate change, a large amount of water resources are wasted in traditional agricultural irrigation, and the improvement of agricultural water utilization efficiency is urgent, so that the identification of plant drought tolerance becomes very important work for plant research. In the prior art, an effective and simple method is always lacked in the aspect of how to determine the drought resistance of crops, a potted plant experiment is utilized, although the water quantity can be controlled, the field state cannot be simulated, the drought resistance experiment carried out in the field cannot accurately control the water content due to the existence of soil, and the identification of plant water absorption can be influenced by the external air condition, so that the experiment result is inaccurate. Therefore, the drought tolerance identification device for the corn seedling stage can effectively solve the problems.
