The shed is full of stress
The “falling vines†is one of the important technical measures to improve lighting, lengthen the growth cycle, and achieve high quality and high yield of shed crops. It is particularly important in the cultivation of solanaceous and melon vegetables. 1. The purpose of falling vines is to make the shed grow stronger and the result cycle is longer. The middle and late mature vegetable varieties elevated in the cultivating have good lighting conditions, improve the lighting position, increase the photosynthetic efficiency, realize high quality and high yield, and facilitate farming. 2. When the plant growth point is close to the roof, remove the yellow, old and diseased leaves from the lower part, and when the leafless stems are more than 30 centimeters away from the ground, they can fall. Generally, it is selected to be warm and sunny in the afternoon. Do not drop in the morning, in the morning or in the evening and after watering, avoid and reduce the damage caused by falling vines. 3, preparation before falling vines (1) water control. Do not water for more than 10 days before falling, reduce the water content of stems, increase its toughness. (2) remove diseased leaves. Before falling, the old yellow leaves and diseased leaves in the lower part of the vine should be removed and taken out of the shed or buried. The part of the fruit should also be removed to avoid the onset of falling leaves and fruit on the wet ground, forming a new source of disease. 4, falling vine requirements (1) loose around the vine. Wrap the stalk of the stalks in the sling and spread the air onto the ground. Do not pull hard scorpions. The vines must be coiled in the same direction on both sides of the cultivation ridge. Be careful to bend naturally. Do not forcibly or reversely bend so as not to twist or break the stem. When the stem is thin, the time between falling vines is short, the circle is small, and after the stem is thick, the interval may be longer and the circle may be larger. (2) leaves and plant height. The leaves and stems were kept at a distance of about 15 cm from the ridge surface. Each plant maintained more than 20 functional leaves. The height of the plant was 0.8 m (shenan) and 1.5 m (shebei). Ensure uniform blade distribution and good lighting. 5. Management after falling vines (1) Temperature. Within a few days after falling, the temperature in the greenhouse should be increased to facilitate the wound healing. (2) Prevent disease. After falling, according to the types of crops and common diseases, timely select the corresponding pharmaceutical spray prevention. (3) Strengthen fertilizer and water management. Falling vines only reduce the plant's result position, but it can not shorten the actual distance between the position of the plant and the root system. In addition, the thick stems, such as insufficient supply of fertilizer and water, will lead to deterioration of the quality of the results. Therefore, it is necessary to guarantee the quality of the fallen vine. Strengthen fertilizer and water supply to meet the fertility requirements of plants. (4) Pruning. After falling, the side branches under the vines of the stems must be wiped out in time to ensure the nutrient supply of the main vines. Other management is performed according to normal management.
