The color of tomato fruit ripening is one of the standards to measure the commercial value of tomato fruit. The poor coloring of tomato seriously affects the quality of the tomato. The coloration of the fruit is uneven, and the taste is poor. There is no sale, and the price will be greatly reduced. Therefore, to strengthen the cultivation and management, to avoid poor coloring of tomato fruit, help to improve the fruit grade of the tomato fruit. 1, a reasonable fertilization Inappropriate fertilizer and water management will affect the normal coloring of fruit. Fertilizer and fungus fertilizer are closely related to the uneven coloration of tomatoes. Therefore, organic fertilizer should be added, nitrogen, phosphorus, and potassium fertilizers should be reasonably applied, and if necessary, compound fertilizer containing boron should be sprayed, which is more conducive to increase production and income of tomatoes. 2, timely watering Can be used under the film dark irrigation, watering should pay attention to small water pouring, can not flood irrigation, pay attention to pouring in the morning, do not pour at noon or afternoon high temperature, so as not to root injury and inhibit the roots of potassium absorption. 3, regulate the temperature During the fruit ripening period, attention should be paid to increasing the temperature. The daytime temperature should be controlled between 25-30 degrees, about 15 degrees at night, and not lower than 13 degrees; in case of low temperature and weak light, it is necessary to intensify the heat preservation, enhance the light and air Light is not good, it will also affect the normal coloring of the fruit. Reasonable planting density is more conducive to photosynthesis and makes tomatoes more evenly colored.
