What is the typical yield per mu of eggplant in jin?
When planting one mu of eggplant, growers will roughly estimate the yield beforehand, and then consider whether the input and output are worthwhile, and whether the output after deducting input is worth it. So understanding other people's yields in advance can give a rough idea. Next, let us comprehensively analyze and understand this.
1. Yield per mu
When planted two seasons a year, with early spring planting, harvest from April to May; summer sowing in May, planting in June, harvest in August. In this way, the yield per mu will increase a lot. If planted one season a year, it is planted in March and harvested from June to July. If 2000 plants are grown per mu, the yield under early spring greenhouse cultivation is 8000 jin. For autumn open-field cultivation, it is about 7000 jin.
2. Greenhouse cultivation
For greenhouse cultivation, sowing should be done around January, and planting around February. The seeds are relatively small and are generally sown directly, but they can be soaked in hot water first, and sown after the seeds absorb water. Sow in seedling trays, cultivate in the greenhouse, keep them on a shallow-water wet cloth mat, and keep them warm and moist. They sprout relatively quickly. Try not to open the door, and occasionally open the top window on sunny days for ventilation. When the seedlings reach transplanting height, they can be planted directly in greenhouse cultivation.
3. Open-field cultivation
For open-field timing, the temperature is still a bit high, so it is not suitable to cultivate in the greenhouse. In open-field cultivation, attention should be paid to moisture retention and cooling. After soaking the seeds, sow them in the seedbed. After sowing, cover with rice straw to retain moisture, and set up a shade net above. After emergence, thin the seedlings, fertilize one week later, and after a few weeks they can be transplanted and planted in the field. After that, normal cultivation and management are all that is needed.
4. Environmental factors
The most suitable temperature for germination is 25 to 30 degrees, and they can germinate above 18 degrees. For seedling growth, keep the daytime temperature above 25 degrees and the nighttime temperature above 20 degrees. The growth and development temperature must not be lower than 15 degrees; below 15 degrees growth is poor, and below 10 degrees growth is disrupted. The flowering temperature is above 20 degrees. Growth requires long periods of high-intensity light, so that it grows well. Before fruiting, it needs less water, and after fruiting it needs a bit more water. But overall, the root system is not well developed, and it needs water but fears waterlogging.
The yield of planting one mu of eggplant is roughly as introduced above. Of course, growing conditions and growing environments differ. Yields will also differ. The above is only a reference to help everyone understand the situation.
