How to Avoid Tomato Flowers Thin and Small？
In the process of tomato planting, the management of flowering period is particularly important, which is related to the quality and yield of tomato fruit.
Supplementary nutrition
The nutritional status of the plant will directly affect the differentiation of vegetable flower buds and further affect the development of fruits. At present, tomatoes have entered the fruiting period. At this time, fruit and seedlings grow at the same time, and vegetative growth and reproductive growth go hand in hand. There is a contradiction between the two for nutrition. How to ensure sufficient nutrient supply is the key to management at this stage. Vegetable farmers should water and fertilize 3 days before flowering. They can use high-quality balanced large-scale elemental fertilizers to halve and fertilize in advance. The amount per mu can be 3 kg to 4 kg, so as to promote rooting, coordinate growth, and supplement nutrition. Multiple functions. If the selected water-soluble fertilizer contains nutrients such as boron and calcium, it can be applied to meet the needs of flower bud differentiation, but when the soil environment is harsh, boron and calcium elements are often inhibited. Therefore, boron-calcium fertilizers should be sprayed before flowering. Calcium fertilizer can choose chelated calcium or mineral molecular calcium, which is good for absorption. While applying a large amount of elemental water-soluble fertilizer, attention should be paid to applying seaweed extract, chitin, humic acid and other functional fertilizers to improve the plant's resistance to stress.
Avoid excessive growth
The excessive growth of plants is one of the main causes of poor differentiation of flower buds and abnormal flowers. Therefore, in the process of vegetable cultivation and management, measures must be taken to control the excessive growth of plants. At present, the temperature difference between day and night is increasing. Vegetable farmers should not blindly use pesticides to control flourishing, otherwise it will easily lead to excessive flourishing control, and the plants will be short and grow slowly. big impact. Commonly used physical control methods include appropriate drought, topping and changing heads, and oblique growth, etc., which play a role in controlling prosperity. When the physical method cannot be controlled, it can be controlled by spraying growth points with booster, chlorophyll, etc.
