Causes and Solutions of low Fruit setting rate of latest Tomato
Tomato is a well-known vegetable, it tastes delicious, is loved by consumers, has a wide range of cultivation, and has high economic value. However, the low fruit setting rate is a headache for farmers, because the fruit setting rate is low, the yield of tomato is low, and the income of farmers is less, so what is the reason for the low fruit setting rate of tomato? How to solve the problem? Let's take a look.
1. Excessive application of nitrogen fertilizer
Most plants can not grow without nitrogen, which can promote plant growth, but if excessive nitrogen fertilizer is applied at tomato seedling stage, it will lead to excessive vegetative growth and overgrowth, which will affect the later flowering and fruiting. In addition, partial application of nitrogen fertilizer will inhibit the absorption and utilization of calcium fertilizer, potassium fertilizer and other elements, resulting in plant malnutrition and low fruit setting rate.
Solution: tomato needs different fertilizers in different growth stages. Nitrogen fertilizer is the main fertilizer in the seedling stage, but it is not suitable to apply too much, so as to avoid excessive growth. When the seedlings are flourishing, the long branches should be removed in time. When the plant blossoms and bears fruit, it is necessary to apply less nitrogen fertilizer and increase the application of phosphorus and potassium fertilizer, which can obviously increase the fruit setting rate.
2. Temperature
The temperature requirement of tomato is relatively high. If the temperature is on the high side in the seedling stage, the plant will grow too vigorously, which will affect the reproductive growth and lead to the decrease of fruit setting rate. In addition, the main temperature should also be in the flowering period, and the suitable temperature is about 25-26 degrees Celsius. When the temperature is not up to standard in cloudy days, ventilation or non-ventilation can be reduced. When the noon temperature is high, ventilation should be strengthened and room temperature should be reduced.
Solution: the temperature should be strictly controlled, it should not exceed 30 degrees during the day and 35 degrees at high temperature in summer, so as not to affect the flower bud differentiation of the plant, which is generally 12-18 degrees at night, which should not be too high, so as to avoid the phenomenon of excessive growth of stems and stalks, resulting in falling flowers and fruits. The temperature can be reduced by shading and watering at high temperature, and the temperature can be increased by reducing ventilation at low temperature.
3. Blind use of growth regulators
Tomato needs other trace elements in addition to conventional nitrogen, phosphorus and potassium fertilizer during growth, so foliar fertilizer or growth regulators are generally sprayed during planting to supplement trace elements to the plant and promote its growth. This is a kind of yield-increasing maturity, but some foliar fertilizers contain some hormones. It will stimulate the rapid growth of plants, resulting in overgrowth, thus affecting the fruit setting rate. In addition, in order to increase yield, many farmers blindly use growth regulators, which will also lead to a decrease in fruit setting rate.
Solution: the use of growth regulators and foliar fertilizer must be reasonable, should not be excessive, too often, generally spray 2-3 times in the flowering and fruit stage.
The above is the introduction of the reasons and solutions for the low fruit setting rate of tomatoes. I hope I can help you. If you want to know more about it, please follow us.

Cucumber is one of the vegetables that require a large amount of boron, which is one of the keys to the growth and development, flowering and fruiting and seed development of cucumber. With the gradual increase of the application rate of chemical fertilizer, the boron element in the soil decreases, which hinders the absorption of boron by cucumber and the yield of cucumber.
