At present, the temperature gradually rises, and the growth of greenhouse plants gradually increases. The reporter learned from the interviews in Shouguang City's Luocheng Subdistrict and the rice field and other places that: At present, many greenhouses such as spring cucumber, pepper, etc. have appeared to be long-term phenomenon, resulting in a small number of cucumber flowers, peppers falling and fruit falling, affecting the vegetables. Yield and quality. How to prevent plant leggy, reporters believe that the following four points should be done. First, control the night temperature. In spring, the temperature rises quickly. If the air outlet is closed prematurely and the grass cover is covered prematurely, it is easy to make the night temperature higher, the respiratory consumption consumes too much nutrients, and the vegetables are prolonged. Therefore, according to the insulation conditions of the greenhouse and the types of vegetables to be planted, it is necessary to adjust the off-wind and shelf-loading time. In good weather, the temperature of the greenhouse can be reduced to about 18°C ​​and off at 16°C. The night temperature of sweet pepper is controlled at 15-17°C; cucumber is controlled at 13-15°C. In fine weather, it may be appropriate to cover or not to cover the floating film, or to put a few grasshoppers, and use a roller shutter to place the shelves several times. The first time, it is first placed on half of the shelf. However, we must listen to the weather forecast in time in the spring and do a good job of insulation before the cold weather. Second, rational watering and fertilizing. After the spring temperature rises, the growth of vegetables is accelerated. In order to meet the needs of plant growth, many vegetable farmers have increased the amount of water applied to the plants, causing the plants to grow in a leggy manner. Therefore, in order to prevent plants from appearing leggy, it must be properly watered and fertilized, and should be based on the growth of the plant and the fruit setting situation. For example, the spring cucumber can not be fertilized before settling the fruit, and no water can be used to cultivate the strong tree. Once again, fruitful results will be given in due course. For the spring cucumber, if the plants are long, they can leave the root melon as early as possible to promote the transformation from vegetative growth to reproductive growth, and then regulate the growth of the plant. However, the root melon should be removed in due course so as not to fall down on the tree and affect the fruit set in the later period. For a large number of color pepper, if the plants grow vigorously, can take more control of the fruit and then control the practice of fruit thinning. Finally, spray plant growth regulators. Plants can be sprayed with 750-1000 times of auxin and 1500-2000 times of chlormethorine after they have grown into prolonged growth. However, when using growth inhibitors in spring, it is necessary not only to pay attention to the amount of use, but also to pay attention to the weather, due to the changeable weather in spring. After the temperature rises, there may be "cold weather". After spraying with growth inhibitors, once the temperature drops, under the dual effects of low temperature and growth inhibitors, it is very easy to cause excessive control of vegetables. Therefore, the use of plant growth inhibitors in the spring must be careful, and the weather forecast should be paid attention to when using it.
