The tomato is a male-female plant and self-pollination plant. However, in greenhouse cultivation, the natural fruit set-up rate is low because of the environmental conditions such as temperature, humidity, light and other conditions in the greenhouse and the soil fertility in the greenhouse. Therefore, plant growth regulators are often used in tomato cultivation for chemical treatment to preserve the fruit. In actual production, flowering and spraying are the most commonly used methods for protecting tomatoes and fruits. However, some vegetable farmers have been using the method of cultivating flowers. This method does more harm than good and is undesirable.
Tomato pods, the amount of drug liquid throughout the spike, compared with the point of the flower, spray flower is too large, and then make the plant nutrition to a large number of transport, so many times, will cause tomato growth weakness, leaves yellow, abscisic acid in the body Increased, the fruit stalk (flower handle) is easy to form at the layer, resulting in falling, falling fruit. Moreover, the anthers have strong systemic absorption and are easily transported upwards through the vascular bundle system. If the anther liquid volume is too large, when accumulated in the plant body to a certain amount, the tomato leaves tend to appear hard, brittle, small, and roll. Hormone poisoning occurs.
Tomatoes bloom, heavy damage to flowers. The tomato is a raceme. The flowering time of the upper and lower flowers differs greatly. The vegetable grower generally spends the second and three flowers opening and only two or three flowers per ear are in the best time for the flower. The flowering time has a great influence on the development of tomato fruit. “Early stagnation and late cracking†is the experience that growers have summed up in Solanaceous Fruits. Unification of flowers, unfavorable to the development of flowers that have not yet been opened and opened, manifest themselves as deformity, empty fruit, large fruit, and few fine fruit.
After the tomato has been drowning, the liquid on the flowering ear is likely to drip onto the lower leaves, causing phytotoxicity and affecting the growth of the leaves.
Therefore, relative to the point of flowering, spray flowers, tomato flowers are more harm than good, it is recommended that farmers to change this approach.
