With more than 20 years of experience in vegetable cultivation, Lao Wang can be said to be an expert in this field. When he noticed that the eggplant seedlings were not growing, he immediately sensed the problem. In contrast, the seedlings of pepper, tomato and cucumber transplanted in the same batch were all growing normally. 
Lao Wang's face was slightly worried, and he believed that this was no accident. Years of experience have made it clear to Wang that there are differences in the adaptability of different vegetables to environmental conditions. On this basis, specific bottlenecks limit the growth of eggplant seedlings. In order to quickly locate the root cause of the problem, Lao Wang began to check the environmental indicators of the eggplant nursery in an all-round way. Temperature, humidity, light, soil pH value, Lao Wang carefully compared the data, but they were all within the normal range. This strengthened Wang's judgment that the limiting factor came from the eggplant itself. Lao Wang carefully took out an eggplant seedling, revealing a professional eye that was accustomed to observation. At first, there were no obvious signs of failure, but when the root system was examined, Lao Wang's brows tightened. Some of the roots are underdeveloped and slightly damaged. "Found you. Wang muttered, finally locking on to the almost hidden question. If it weren't for his wealth of knowledge and keen intuition, he would not have noticed the hidden dangers of the root system until the eggplant died. After confirming the cause of the slow growth of eggplant seedlings, Lao Wang began to investigate the underlying factors that led to the underdevelopment of the root system. Relying on years of cultivation experience and theoretical knowledge, Lao Wang decided to start the specific analysis from three aspects: temperature, humidity and soil pH value. Temperature is particularly important for eggplant root growth. After reviewing a large number of research data, Lao Wang concluded that the minimum temperature line for eggplant root growth is about 15°C, and if it is lower than this temperature, the growth rate will drop significantlyWhen the temperature exceeds 35°C, the eggplant root system will also stop growing. 
Considering the growth situation, the optimal temperature range for eggplant root growth is 20-25°C. Relative humidity is also a key factor. Combined with measuring instruments, Lao Wang detected that the relative soil moisture of 80-90% needs to be guaranteed during the growth period of eggplant roots. Excessive humidity or drought can inhibit the ability of roots to absorb water and nutrients. Therefore, just the right amount of moisture is essential for the vitality of eggplant seedlings. In addition to the above two key indicators, soil pH also had a certain impact on the morphology and function of eggplant roots. Detailed measurements show that a pH value close to neutral is ideal, at around 65-7.0. 
Acidic or alkaline soils will reduce the uptake and utilization of soil nutrients by eggplants. After a detailed analysis of the environmental requirements for the growth of eggplant roots, Lao Wang decided to compare it with other vegetables raised in the same period. There are still subtle differences between similar vegetables, which may shed more light on the root system of eggplants. It was found that cucumbers and tomatoes grew much faster than eggplant roots. Measurement data shows that under suitable conditions, cucumbers and tomatoes can be quickly extracted in just 2-3 days, far exceeding the root generation time of eggplants. In addition, there were differences in the dependence of different vegetables on root structure and growth traits. For example, tomatoes are born with strong root growth, and as long as the root system is intact, the requirements for external conditions are not high. 
The root system of eggplant is extremely sensitive to environmental changes, and the slightest unfavorable condition will show growth retardation. After comprehensive analysis, Lao Wang identified an important bottleneck in the root growth of eggplant - the root structure is not developed enough, resulting in high sensitivity to the external environment and poor stress resistance. This is in stark contrast to vegetables such as tomatoes, cucumbers, etc. Clarifying this key conclusion provides an important significance for Lao Wang to improve the root growth of eggplant in the future. After finding the root cause of the stunted growth of eggplant seedlings, Lao Wang acted quickly to reverse the passive situation. He first carefully groomed the roots of the eggplant seedlings, removing obstructions and adjusting the angle to ensure that the roots could absorb water smoothly. 
Then, Lao Wang changed into a full set of protective equipment and meticulously loosened the soil and fertilized the eggplant seedlings. Based on the preliminary analysis, he carefully formulated a medium with balanced nutrition and moderate pH value, which laid a solid foundation for the rejuvenation of the eggplant root system. This is followed by careful watering and care for the eggplant seedlings. Lao Wang spares no effort to monitor the soil moisture, and replenishes the water in time when it drops slightly. Sometimes in the dead of night, Lao Wang will unconsciously come to the eggplant nursery and whisper a few words, as if encouraging the weak eggplant seedlings to regain their strength. Under such careful care, the dying eggplant seedlings finally ushered in a turnaround. The first sprouts were a little floaty, but they soon settled down and began to grow rapidly upward. Seeing this scene, Lao Wang's eyes were full of tears of relief. 
After the eggplant seedling problem was solved, Lao Wang thought about and reviewed the matter repeatedly, and learned lessons from it. He believes that as a senior vegetable cultivation expert, he still lacks an understanding of the importance of the root system of eggplant seedlings, and he has not paid close attention to the root growth from the beginning, which is an unforgivable dereliction of duty. This "crisis" made Lao Wang deeply ashamed. It also made him realize once again that vegetable growth seems simple, but in fact, it integrates many disciplines and needs to properly control many factors. At the same time, Lao Wang also re-realized that solving problems requires enough patience and perseverance. Just like when recuperating the root system of eggplant seedlings, there can be no slackness. In short, Wang is determined to learn from this experience and further improve the monitoring and response mechanism. He believes that as long as he continues to reflect and learn Xi modestly, he will definitely be able to improve his cultivation skills and usher in a better harvest.
