The reason for the face is the variety reason, the variety is easy to color unevenness; the second is the excessive nitrogen fertilizer during the growth process, the more chlorophyll, the inhibition of lycopene formation, uneven coloration; the third is the coloration of the third ear fruit Period, the temperature difference between high temperature and day and night will be large, and uneven coloration will also occur.
Measures to solve the face: Choose a good variety, use the new high-fat membrane seed dressing before planting to keep warm, moisturize, and swell, improve the seed germination rate, and make the seedlings strong. Repel underground pests and isolate viral infections. It can also be mixed with a seed coating. Reasonable retention of fruit, attention to ventilation and light transmission, control of nitrogen fertilizer, application of phosphorus, potassium fertilizer and organic fertilizer, foliar application of foliar fertilizer and photosynthetic nutrient film fertilizer, can help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizer The nutrient supply plants grow to the limit. One-year benefits for one application. Reasonable irrigation. Before flowering, in the young fruit stage and in the expansion stage, the fruit juice Zingling can be sprayed once, which can activate the plant ecological growth positive energy, broaden the plant conduit path, enhance the water absorption and fertilizer absorption of the plant, increase the fruit yield and quality, and reduce the fruit drop rate. Reduce the incidence of cracked fruit, stiff fruit, and deformed fruit. Note that in the fruit expansion period, it is necessary to supplement trace elements such as potassium, calcium and boron to increase the photosynthetic conversion rate.
