1, temperature reasons. The temperature of the greenhouse is too low, especially if the temperature is too low in the middle of the night, which leads to the impediment of the conversion of lycopene and the difficulty of coloring the eggplant. Solanaceous vegetables had the best lycopene formation at 24°C.
Solution: timely adjust the temperature and spray a new high-fat film to form a layer of polymer film, heat and moisture to prevent bacteria, the results during the day temperature control at 25 °C -30 °C, night temperature with 16 °C -20 °C is appropriate.
2, light reasons. The eggplant is a hi-light crop. The lack of light produces weak growth and yield, the pigment is not easy to form, the fruit color becomes lighter, and it is easy to produce variegated colors. In particular, the purple eggplant is not easy to be colored, which directly affects the commodity price. In addition, under low light conditions, if malnutrition occurs again, it will increase the occurrence of poorly colored fruit. Weak light, even rainy weather, worsening the degree of fruit coloring. Solution: Under the premise of adjusting the temperature in the shed, properly remove the aging leaves from the lower part of the plant, combine the regular wiping film, and spray the photosynthetic nutrient film fertilizer to help the plants absorb large amounts of light, light, light, and compatible conventional fertilizers. , Nutrients supply the plant growth and development to the limit. Apply once a year to benefit.
3, nitrogen fertilizer reasons. Excessive application of nitrogen fertilizer, nutrient growth is too strong, resulting in the fruit is not easy to color. Excessive application of nitrogen fertilizer, especially excessive nitrogen fertilizer during the late growth period, will make the plant grow too serious, so that the leaves will squeeze and cover each other and affect the ripening of the fruit, resulting in poor coloration.
Solution: In the later period, the use of nitrogen fertilizer should be reduced as much as possible. If the plants are not growing well, some new high-fat membranes and foliar fertilizers can be sprayed to solve the problem. If there is a phenomenon of prosperous growth and prompt application of Huawang No. 3, it will force a large amount of nutrient backflow at the top of the tip, and the inertia advantage of the red tip will quickly weaken to the top of the cap. The main nutrient of the main body shifts to the young fruit development system, enhances the vitality of fruit enlargement, avoids the phenomenon of leaf hypertrophy, and improves field permeability.
