Planting techniques of coriander in summer 1, variety selection
Due to the high temperature in summer, which is more than 25 degrees Celsius most of the time, the growth rate of coriander is slow, and it will affect the quality of coriander. Therefore, it is necessary to choose varieties that are drought-resistant, strong-light-resistant, bolting late and growing fast to improve the germination rate of plants.
2. Soil preparation and fertilization
In summer, coriander is planted out of season, which has certain requirements for soil. It is necessary to plough the land first to ensure that the fertilizer and water in the later period can penetrate into the root system, and then apply enough farmyard manure or compound fertilizer as the base fertilizer to mix the soil and fertilizer evenly to promote plant absorption.
3, timely sowing
The time for planting coriander in summer is about June, and the seed consumption per mu should not exceed 2kg, so as to ensure the yield and quality of the plant, and the planting density should not be too small. Just sow it evenly according to the spacing of 3-5cm, cover it with straw after sowing, and uncover it one week later.
4. Field management
The high temperature environment in summer will affect the normal growth of coriander. Therefore, after uncovering the straw, it is necessary to build a sunshade for it in time, cover it during the day and uncover it at night, strengthen the ventilation in the shed, and start thinning seedlings one week after the seedlings are neat, and the planting distance is about 3 cm.
