Recently, the uneven coloration of the fruit during the harvest period has become a focus issue. This phenomenon has seriously affected the market sales prices of tomatoes and the income of farmers, making farmers a headache. To determine the quality of tomatoes, in addition to their own varieties, scientific fertilization is also the key. Scientific practice shows that when applying base fertilizer to tomatoes, the application of golden baby microbial fertilizer can supply sufficient nutrients during the fruit enlargement period of tomato and increase the resistance of tomatoes to high temperature and drought, such as the combination of foliar spray and golden sweetening colorant. , can promote the formation of lycopene, improve the conversion rate of photosynthesis, which is conducive to the accumulation of carbohydrates and sugar, increase the weight of tomatoes. What are the reasons for the uneven coloring of tomatoes? The analysis of the main causes of unequal coloring of tomatoes and the best solutions are as follows for your reference: First, the variety of tomatoes. The varieties of tomatoes vary, and the internal quality factors and stress resistance of each variety are not the same. Therefore, the appearance of external phenomena is different. For example, large-scale fruit Xifen No. 3, early-maturing and high-yield, strong drought resistance, anti-virus and disease. There are also varieties such as Nongda 704, Liaofenzasan, Zhongnong 4 and so on, all of which are relatively resistant varieties. Therefore, growers should carefully consider the variety. Second, there is excess nutrition. From the young fruit stage to the fruit harvest stage, the nitrogen fertilizer is in excess, and the chlorophyll formation is more likely to inhibit the formation of lycopene, and yellow or green patch spots appear on the surface of the fruit. This phenomenon is mainly due to the excessive use of base fertilizer nitrogen fertilizer, phosphorus and potassium fertilizer deficiency, resulting in tomato plant leggy. If you can use the basic microbial fertilizer microbial fertilizer in the base can activate the insoluble phosphorus and potassium elements in the soil to provide balanced nutrients to tomatoes, promote the accumulation of nutrients conducive to the formation of lycopene. And it can effectively prevent premature aging of plants. Again, potassium and boron are lacking. Potassium is a quality element that determines the coloration of tomatoes and the transport of carbohydrates and amino acids. Boron is a breeding element that determines the fruit setting rate of tomatoes, promotes the formation of carbohydrates and amino acids, and reduces cluster necrosis of the top growing point and the combined necrosis of stems. During the fruit enlargement period, the golden treasure sweetener is sprayed, which can supplement the trace elements such as potassium, calcium, boron, etc., increase the conversion rate of photosynthesis, and facilitate the accumulation of sugar. Finally, there is a large temperature difference between day and night. During the fruit coloring period, the temperature of the tomatoes is higher than 32°C and lower than 8°C, which is not conducive to the formation of lycopene. The yellow-green spots formed on the surface of the fruits at these two temperatures are yellow and green even if the tomatoes are adapted to this temperature. Spots cannot disappear. The nighttime temperature of the greenhouse is too high and the respiratory intensity is increased, which is not conducive to the accumulation of nutrients. Therefore, the temperature is controlled at 25-30°C, and the night temperature is controlled at 15°C. Therefore, the best solution for the uneven coloration of tomatoes is to select good varieties and base fertilizers to be used for chemical fertilizers together with the application of the microbial fertilizer. The pre-flowering, young-expiration, fruit enlargement to harvesting period, and the application of the sweetening colorant of the golden treasure can not only increase the production and sweetening effect, but also can significantly improve the phenomenon of unequal coloring of tomatoes, and ultimately increase the income of the growers.
