First, choose the best species. Choose varieties that are drought-resistant, heat-resistant, fast-growing, and not easily convulsed, such as Beijing parsley, American leafy parsley, and Thai heat-resistant large-grained parsley.
Second, seed processing. In summer, the temperature is high, and the water in the soil evaporates quickly. In order to emerge early and grow seedlings, the seeds must be treated before sowing, that is, the seeds are first peeled off and the seeds soaked. Seeds can be soaked in cold water for 4-5 hours. The seeds are placed in a cotton bag and germinated for a week at a temperature of 15°C in a dark, moist environment. When the seeds are white, they can be sowed.
Third, soil preparation and fertilization. Choose fertile land with fertile soil, water and fertilizer, drainage and irrigation facilities, and well ventilated land. It is best to not cultivate parsley plots within 3 years. Mu Shi farmyard fertilizer 3000 kg, high-nitrogen low-phosphorus potassium compound fertilizer 50 kg, spread the fertilizer evenly, rotating the land, do grow 5-6 meters flat to be broadcast.
Fourth, fine sowing. The sowing method is often used in production. Before sowing, sufficient water is poured into the bowl. After the water is permeated, the seeds are mixed with sand and spread uniformly, and then spread and covered with 1-2 cm thick fine sand. After all the broadcasts were finished, use a hoe to suppress it once. Covering old grasses, straws, and other coverings can help maintain warming and cooling. After about 7 days of general sowing, it is possible to produce seedlings, which will be removed when most of the seedlings are unearthed.
Fifth, field management. Parsley is afraid of high temperature and strong light. Where conditions permit, it may be considered to cover shade nets on cultivated earthworms to achieve the effect of cooling and shading, which is beneficial to the growth of coriander, increase yield, improve quality, and increase planting efficiency. There was no field that closed the herbicide. In the seedling stage, it was combined with cultivating and cultivating. The field weeds were removed in time to prevent competition with the parsley and compete for water. The principle of the management of fertilizer and water in the growing period of coriander is no drought and no irrigation, and watering at the seedling stage is sufficient to maintain adequate water and fertilizer supply during the prosperous period. Top dressing depends on the strength of the land, combined with watering, topdressing urea or nitrogen and potassium fertilizers, generally 15 kg per fertilization, continuous top dressing twice.
Six, control pests. The main insect pests of the summer cilantro are maggots, which are extremely common under high temperature and drought conditions. They generally suck the sap of the leaves of the coriander and cause a reduction in production. 10% of imidacloprid can be used to control 800 times spray, spraying once every 7 days, spraying 2-3 times.
Seven, appropriate harvest. The summer cilantro grows faster and should be harvested as soon as possible to achieve the harvesting standard. When the plant grows to 20-25 cm in height, harvesting can begin. In order to improve its merchandise, the harvest time is generally after 6 pm or early morning for harvesting, and timely sale after the harvest.
Natural pigments are food pigments obtained from natural resources. Pigments extracted mainly from animal and plant tissues and microorganisms (cultures), in which vegetative colorants predominate. Natural pigments not only have the function of coloring food, but also have physiological activity. At present, there are 48 kinds of edible natural pigments approved to be used in China, commonly used chili red, beet red, monascus red, cochineal red, gaolianghong, sodium copper chlorophyllin, turmeric, gardenia yellow, carotene, algal blue pigment, cocoa pigment, caramel pigment and so on.
