Key Techniques for Improving the Fruit Setting Rate of Eggplant

1. Topping: The fruit setting rule of eggplant generally increases with the tillering of the plant, basically one fruit per branch. Most of the ostriches are one, two for the eggplant, four for the four cigars, and eight for the octahedron. Therefore, in management, this feature should be fully utilized, and topping should be carried out in time after planting to promote rapid tillering, increase the result area, and increase the fruit set rate.

2. Promote weak control Wang: The growth of eggplant plants is weak, and the lack of nutrition will aggravate the falling flowers and fruits; but if the growth is too strong, it will also cause the flowers to fall. Therefore, maintaining normal (not prosperous or weak) growth is the basic requirement for promoting eggplant into flowers and fruit. Therefore, for plants with weak growth, they should be enhanced by applying fertilizer water. If the growth is too strong, the fertilizer should be properly controlled to promote normal growth and increase the fruit set rate. The specific method is: strengthen the management of fertilizer and water for weak seedlings, mainly organic fertilizer and available phosphorus in the early stage, and use quick-acting nitrogen fertilizer in the middle and late stage. It is best to apply 500-600 kg of decomposed and diluted manure per mu when the eggplant is flowering. Cake fertilizer 20 ~ 30 kg, superphosphate 15 ~ 20 kg. After entering the fruiting period, the topdressing should be directed to quick-acting nitrogen fertilizer (10-15 kg of urea per acre), and 3 to 5 times in the result period. At the same time, we must pay attention to watering in combination with top dressing. For Wang Miao, the stems of the plants can be pinched at the flowering stage to promote the accumulation of photosynthetic products and promote fruit set. It is also possible to reduce the growth of nutrients and water by reducing the roots of the plants, and to ease the growth and promote the results. .

3. Hormone treatment: Spraying with 20ppm of anti-falling pigment at flowering stage, or using 2~4-D sputum of 30-40ppm, can achieve the purpose of preventing falling flowers and fruit, and improve the fruit setting rate.
