Coffee Huang Kui likes warmth and is afraid of frost. The whole growth period should be arranged in the frost-free period, and the flowering and fruiting period should be in the warm and humid seasons everywhere. Open field cultivation, sowing in April-June and harvesting in July-65438+10, can be used all over the country. Sowing in North China is usually in the middle and late April to May. In northern cold areas, sunlight greenhouses and plastic greenhouses are often used to raise seedlings, and then they are planted in the fields after early spring and late frost.

In general, the whole seedling fertilizer is used to raise seedlings after seeking to expand sowing. Because seeds germinate faster or slower, the fields look irregular and uneven, which makes people look a little underdeveloped. Therefore, the first topdressing is usually carried out three days after emergence. This kind of fertilization is mainly to make the seedlings look neat, so we usually use urea to promote the growth of okra seedlings. An average acre of land needs about 100 kg of urea, which is fertilized by spraying.
