Three measures to promote uniform tomato coloring
Right now, many of the first fruits of Qiuqiu tomatoes are about to enter the coloring period. How to take effective measures to help the tomato fruit color evenly become the most concern for vegetable farmers. In this issue, we will focus on the details. The reporter will give you a detailed summary of the measures that will help the coloring of the tomatoes' fruits: 1. The temperature is well controlled. Too much or too little temperature during tomato coloring can affect the formation of lycopene. Studies have shown that the optimal temperature for the formation of lycopene is 19-24°C, and a shed temperature lower than 14°C or higher than 32°C will affect the normal production of lycopene. Therefore, the current temperature control of vegetable farmers should be 22-26 °C during the day, 15-20 °C at night is appropriate. 2. The light should be sufficient. Remove dust and contaminants from the shed film in time to ensure sufficient light conditions and promote fruit coloring. After the grasshopper has been planted, it is necessary to expel as soon as possible the late ganoderma lucidum to increase the lighting time of the tomato fruit. When necessary, it can be timely. Excessive branches, old leaves, diseased leaves, residual leaves, and hanging curtains on the back wall should be removed to increase the illumination time of fruit in the shed and promote fruit coloring. 3. Water and fertilizer supply should be balanced. Unreasonable application of fertilizers will seriously affect the coloration of tomato fruits. For example, if there is too much nitrogen, the growth of the plants will be too strong. If there is insufficient water, then green shoulders will occur; if there is a lack of nitrogen, the shoulders will be yellow; when potassium is lacking, The shoulders appear yellow-green and the vascular bundles of the heart and the fruit are lignified; in the absence of boron, the fruit shoulder remains green with necrotic spots. Prevention and control measures: Timely replenishment of nitrogen, phosphorus and potassium fertilizers, and use one kilogram of borax to supplement boron fertilizer. At this stage, in fine weather, depending on soil moisture, water can be poured every 10 days or so. In addition, from the beginning to the end of the current period, the fruit of each ear must be top-dressed in an inflated period, and full-nutrition, fully water-soluble fertilizers can be used for flushing. For instance, Fang Run (15:15:30) and Le Bar (20:10: 30) etc., 10-15 pounds of mu shall be fully supplemented with nutrients so as to prevent the occurrence of poor fruit coloration due to imbalance of nutrient supply.
