Suitable planting time of coriander in summer
The planting time of coriander in summer is generally around June, and the planting amount per mu should not exceed 2 kg, which can improve the quality of coriander and the planting density should not be too small, so as not to affect the harvest in the later stage.
When sowing, we should spread coriander seeds evenly in the soil, and then cover them with plastic film, which can be removed in about 7 days, but keep the soil moist.
planting methods and key points of coriander in summer
1. Selection of varieties
Because of the high temperature in summer, the growth rate of coriander will become slower, which will also affect the quality of coriander. When it exceeds 3℃, it will stop growing. Therefore, when selecting varieties of coriander, it is recommended to choose varieties that are drought-resistant, sunlight-resistant and grow faster, which will not affect the quality of coriander.
2. Soil preparation and fertilization
Because coriander is planted out of season, there are certain requirements for the soil. First, loosen the soil to ensure that fertilizer and water can penetrate into the roots of coriander. Before planting, we must apply foot manure, decomposed farm manure and compound fertilizer, and then mix the soil to fertilize, so as to better let coriander absorb nutrients.
Points for attention in daily management of coriander in summer
Intercropping should be carried out in time, usually when the coriander seedlings are about 4 cm. Weak seedlings should be removed, good seedlings should be kept, so that the coriander seedlings can grow better, and weeds should be removed at the same time to prevent weeds from robbing the nutrients in the growth process of coriander.
