What should you do when autumn tomatoes fail to set fruit? Here are the solutionsThe main reasons autumn tomatoes fail to set fruit are incomplete flower bud differentiation - some flowers only differentiate sepals without properly developing the pistil, stamens and pollen, and so on. When flowers fail to set after treatment, the tomato plants grow excessively vigorously and take up too many nutrients, so the nutrients absorbed by other organs such as flowers and fruits - the reproductive organs - are greatly reduced, reproductive growth becomes insufficient, and the flower buds cannot differentiate normally, thus affecting the normal growth of the tomatoes.
For autumn tomatoes failing to set fruit, you can refer to the following methods:
1. Temperature management: the temperature inside the greenhouse should not be too high, especially the nighttime temperature, otherwise the stems will grow leggy and flowers will easily drop. You can lower the temperature inside the greenhouse by shading and spraying clear water, and at the same time spray Cuihuawang No. 3 to inhibit excessive growth of the main shoot and promote flower bud differentiation.
2. Remove leaves: you can remove some of the vigorously growing leaves to adjust the growth of the tomatoes, and water and fertilize appropriately during the growth stage, supplement more boron-calcium foliar fertilizer, and spray Caiguo Zhuangdiling during the flowering and fruiting period of the tomatoes to improve pollen quality, enhance the fruit-setting rate over successive cycles, and keep the tomatoes producing steadily and with high quality.
3. Artificial supplementary pollination: during the flowering period of the tomatoes, carry out artificial supplementary pollination in good time to increase the fruit-setting rate, and spray Xingao Zhimo during the young fruit stage to act as a liquid film bagging, which will not affect fruit respiration, prevents fruit rust disease and fruit cracking, improves the coloring and glossiness of the fruit surface, reduces residue and improves quality.
