Key techniques for improving Fruit setting rate of eggplant

1. Heart-picking: the fruit-setting rule of eggplant generally increases with the bifurcation of the plant, basically one fruit for each branch. For example, most of the door eggplant is one, two for the eggplant, four for the four mother eggplant, and eight for the octagonal eggplant. Therefore, in management, we should make full use of this characteristic and pick the heart in time after planting, so as to promote its rapid bifurcation, increase the fruit position and improve the fruit setting rate.

two。 Promote weakness and control prosperity: eggplant growth is weak, lack of nutrition, will aggravate flower and fruit drop; but excessive growth will also cause flower and fruit drop. Therefore, maintaining normal (neither prosperous nor weak) growth is the basic requirement to promote eggplant flowering and fruit setting. Therefore, for the plants with weak growth, they should enhance their growth by applying more fertilizer and water, and those who are too prosperous should properly control the fertilizer and water to promote their normal growth and improve the fruit setting rate. The specific measures are as follows: strengthening fertilizer and water management for weak seedlings, mainly organic fertilizer and available phosphorus in the early stage, and quick-acting nitrogen fertilizer in the middle and later stage, preferably in the flowering of eggplant, topdressing 500 kilograms of mature dilute manure per mu or 20 kilograms of cake fertilizer and 15 kilograms of calcium superphosphate per mu. After entering the full fruit stage, topdressing should be mainly based on available nitrogen fertilizer (1015kg urea per mu), and topdressing for 3 times in the fruiting period. At the same time, we should also pay attention to watering combined with topdressing. Excessively prosperous seedlings can pinch the stem of the plant at the flowering stage to promote the accumulation of photosynthates and promote fruit setting; it can also injure the root in the middle tillage, weaken the absorption capacity of nutrients and water, ease the growth and promote the fruit.

3. Hormone treatment: spraying flowers with 20ppm anti-falling hormone at flowering stage, or dipping flowers with 30~40ppm 's 2Magazine 4murD can achieve the purpose of preventing falling flowers and fruits and increasing the rate of fruit setting.
