How can the coriander plant produce high yield and good quality? Before the coriander was not so hot, since the Shouguang flood disaster, more and more people pay attention to the cultivation technology of coriander, let's learn the key points of coriander cultivation together.
First, soil preparation and fertilization
Before planting, the land should be fertilized on the site, and the sandy loam soil with loose soil and fertile soil should be selected. Combined with tillage, 3000 kg of decomposed manure per mu should be used as base fertilizer, and then 2 m wide. How the soil is too dry, watering to keep it moist, waiting for planting after the soil is finely leveled.
Second, choose a good species
Coriander is generally selected to grow fast, heat-resistant, disease-resistant and adaptable, and coriander can be divided into large leaf and lobular varieties. Although the yield of lobular varieties is not as good as that of large leaves, its flavor is rich and cold-resistant. Force and adaptability, so the lobular variety is generally chosen.
Third, germination sowing
Coriander is cold and suitable for growing at a temperature of 15-20 degrees. Therefore, the sowing time is generally from August to April. In order to increase the germination rate before sowing, the seedlings are neatly tidy. First, put the seeds into warm water of about 50 degrees, stir and soak for 15-20 minutes, wait for the water temperature to drop, continue to soak for 18-20 hours, germination in the greenhouse environment, soak every 2-3 days, After 10 days, the seeds are white and can be sown. Sowing can be carried out or spread. Generally, 2 kg per acre is planted. After sowing, a layer of straw should be covered on the ground, and water should be sprayed frequently to keep it moist. When the seedlings are released, the straw should be removed in time, and the seedlings and seedlings should be prepared.
Fourth, field management
Coriander is cold, but it is afraid of high temperature and strong light. Therefore, it is necessary to consider covering the shade net when planting, which can play the role of shading and cooling, which is beneficial to the growth of coriander and increase the yield. In the seedling stage, the loose soil can be combined to remove the weeds in the field, so as to prevent them from taking up the nutrients. In the growing season, the soil should be kept dry and not wet. In the seedling stage, water should be poured as little as possible, and in the vigorous growth, sufficient fertilizer should be supplied. To make it grow fast, fertilization is mainly based on urea and nitrogen and potassium fertilizer, and 10-15 kg of fertilizer per acre can be carried out together with watering.
V. Harvesting
Because the growth of coriander in the greenhouse is faster, it should be harvested in time after reaching the harvesting standard, so as to avoid the phenomenon of convulsions. Generally, the coriander can be harvested when it grows to 25 cm. The harvesting time should be well mastered, and it is best to harvest it in the morning and afternoon, which will help to increase the value of the commodity.
