Tomatoes in the near future can not stand fruit?
In the past few days, many tomato growers in Shenzhou, Hebei Province and Shan County, Shandong Province, reported to the special expert Yuanzhang Hu of the newspaper that the tomatoes couldn't stand flowers, the flowers dropped heavily, the plants grew weak, the stems were thin, and the heart color was yellow. Teacher Yuan pointed out: This is mainly caused by the weather. Since the beginning of the autumn, temperatures have been high, and over the past period of continuous rain, the photosynthesis of the leaves has declined. The lack of nutrients in the plants and the lack of nutrition in the flower buds have led to the loss of flowers. Experts suggest that the following methods should be adopted to solve: increase the light transmission performance of the film as much as possible, and increase the photosynthetic efficiency. Second, take measures to reduce the night temperature. Today, the night temperature has been reduced, to make full use of it, pull the greenhouse temperature difference between day and night, reduce respiratory consumption, to ensure that the organic nutrition of the leaves can maximize the supply of flowers, fruits and other nutritional organs growth and development needs. Finally, the leaves were sprayed with chitin, nutrient foliar fertilizer, glucose and other supplementary nutrients to regulate plant growth. In the point of anther, at the present stage, it is possible to use 10 ml of anti-dropping agent, dilute 0.8-1.2 pounds of water, and spray or spray flowers. It should be pointed out that the concentration of the anti-dropping agent has a great relationship with the temperature, medication equipment, etc. It is recommended that the vegetable farmers make a trial before using it in large areas. With the arrival of a cool climate and fine weather in autumn, combined with the right management practices, the fruit setting of tomatoes will be greatly improved.
