The latest course of field management techniques and methods of coriander

Coriander, also known as coriander, is a common seasoning vegetable in our life. It is rich in nutrition and spicy in taste. It is loved by people. In order to obtain high yield and improve the quality of coriander, field management is extremely important. So how should coriander be managed in the field? Let's take a look.

1. Seedling management

Parsley can sprout in about 10 days after sowing. If it rains heavily during seedling emergence, the soil in the field will harden after the weather clears, which will affect the emergence of parsley. Therefore, at this time, it is necessary to water once in time to maintain the permeability of the soil, so that it can emerge smoothly. When the coriander grows to 4-5cm, it should be thinned in time. If the seedlings have enough growth space, the inferior seedlings should be removed when thinning, and the seedlings with uniform growth size should be retained.

2. Intertillage and weeding

In addition to thinning seedlings, seedling management also has an extremely important job, that is, intertillage weeding, weeds will lead to poor permeability in the field, will occupy nutrients, affect the growth of seedlings, and weeds are still maintained hosts, too many weeds, plants easy to press pests. Therefore, weeds should be removed in time as soon as they appear in the field. It is recommended to pull them out manually. If the soil is too sticky or watered improperly, it is easy to cause soil hardening and poor growth and development of coriander root system. Therefore, it is necessary to cultivate in time, and it is not suitable to cultivate too deep in seedling, so as not to cause damage to root system.

3. Fertilizer and water management

The growth period of coriander is relatively short, generally fast 40 days, slow two months can be harvested, so fertilizer must be early, in the seedling stage should not be watered too much, watering once every 3-4 days, but in the growth season to strengthen fertilizer management. Water frequently to keep the soil moist, fertilization is based on quick-acting fertilizer, combined with watering together, can be sprayed or irrigated, early irrigation of 1000 kg of human manure or urea 4 kg of 1-2 times, late irrigation once a week compound fertilizer 50-10 kg can be. In addition, thin fertilizer should be applied in time after harvest, and gibberellin should be sprayed once before harvest, which can significantly improve yield.

4. Pest control

The main diseases and insect pests of coriander are leaf spot disease and aphid, which affect the yield and quality, and affect the income of farmers. The prevention and control of them are mainly based on agricultural control, physical control, biological control, and chemical control. Chlorothalonil and carbendazim can be sprayed at the early stage of leaf spot disease, while abamectin and imidacloprid can be sprayed at aphid outbreak.
