Some time ago, the autumn season was overcast and rainy. It was not how the sun was seen for more than half a month. This kind of weather had a great impact on the growth of autumn cucumbers. Not only was the yield extremely low, but it was also prone to diseases, leading to premature aging. In response to this issue, farmers are reminded to take care that they must take measures as soon as possible to avoid premature aging. First, increase the temperature difference between day and night to increase lighting in the shed. Even cloudy days, due to lack of light in the shed, the accumulation of photosynthetic products is small and consumes much, which is one of the causes of premature aging. During this period of time, the daytime temperature in the shed should be controlled to 20-30°C, and the night temperature should be 12-15°C. The light in the rainy shelter room is weak, and the greenhouse film should be wiped in time to increase the light intensity of the greenhouse, increase the accumulation of nutrients in the leaves, and prevent premature aging of the leaves. At the same time, special attention should be paid to the management after sunny days, because of the large leaf area and high transpiration coefficient of cucumber, the root system is not particularly developed and is easily injured. After a sudden fine weather, the light and temperature change rapidly, and the plant Hurt a lot. Therefore, shade should be properly shaded after the transfer, and the light and temperature should be gradually adjusted so that the plants can gradually adapt to changes in the environment, so as to reduce the damage to the plants in the shade. Second, strengthen root care and ensure nutrient absorption. The root system of cucumber is relatively shallow, mainly distributed in the topsoil layer within 20 cm, which is greatly affected by the environmental changes such as ground temperature, water, and fertilizer. Therefore, the maintenance of the root system should be strengthened before and after cloudy days. Even during cloudy days, the evaporation of the plants is very small. Unless it is particularly arid, it is best not to water, so as to avoid excessive humidity in the shed, causing problems such as roots. Even after a cloudy day, it is not suitable for immediate watering, because at this time it is in a period of plant recovery, and the root activity is still relatively weak. If it is watered too early, the root system will become more affected and the plants will appear wilting and other problems. It is recommended that 3-4 days after the end of cloudy days, the plant roots and other recovered and then top-dressing. At this time, the root system is weak, alginic acid, chitin, and humic acid fertilizers, which are conducive to rooting and rooting, should be selected. At the same time, nutrition can be supplemented with total water-soluble fertilizers, such as Fangrun, Leba, etc., at 3-5 kg ​​per mu. You can. Remind farmers to pay attention to avoiding the use of poor quality paste fertilizer with high hormone content. Although hormones can promote rapid rooting, they can easily cause premature plant failure. Finally, the leaves were supplemented with nutrients and the plant growth regulators were applied rationally to improve the resistance of the plants. Even cloudy plants lack nutrition and growth is weak. Attention should be paid to the nutrition of the foliage to enhance the resistance of the plants. Foliar can be sprayed with full-grown foliar fertilizer, chitin, and alizarin lactone to supplement leaf nutrient, promote chlorophyll synthesis, and increase photosynthetic efficiency.
