White coriander: white coriander mature late, is a cold resistant, fertilizer loving varieties, suitable for planting in the suburbs of Shanghai.
Lavender coriander: also known as purple stem coriander, its plant is relatively short, cold resistant, but low yield. Planting method of coriander (basic knowledge): the best planting time: planting coriander, the sowing time is not strict, generally from May to June.
The best growing soil: the soil with good soil structure, strong fertilizer and water retention, and rich in organic matter is the most suitable for coriander growth.
Requirements for growth humidity: coriander is a shallow root vegetable with weak absorption capacity, so it has strict requirements for soil moisture and nutrients. The soil with strong water and fertility conservation and rich organic matter is most suitable for growth. The range of adaptability to soil pH is pH 6.0-7.6.
The best growth temperature: the best temperature is about 17 ° to 20 ℃. Coriander grows slowly above 20 ° and stops growing above 30 ℃.
The best growth light: the light requirements are not strict, enough light can be, if the light intensity is too strong, it needs appropriate shading.
Green coriander coriander planting precautions: 1, breeding points: the main way of propagation of coriander is sowing propagation.
Coriander can be planted in spring in southern provinces and in spring and summer in northern China. Before planting coriander, it is necessary to sow and raise seedlings first. After the seeds are collected, their skins should be rubbed open, and then put in the basin soil which is watered with water. The seeds can germinate in about seven days. After germination, coriander seeds can be moved to fertile soil.
2. Temperature and fertilization: coriander grows fastest when the external temperature is between 15 and 20 degrees. If it is planted in summer, attention should be paid to cooling. Topdressing is best not topdressing, if the base fertilizer is not enough, topdressing can be carried out about 10 days before harvest. The concentration of urea is 1.5%, which can be sprayed twice. If you want to keep your own seeds, you need to add some phosphate fertilizer.
3. Watering points: generally do not water before fixing seedlings, so as to control the upper and promote the lower and strengthen the roots. After fixing the seedlings, the water should be poured once in time so as not to submerge the seedlings. With the vigorous growth of seedlings, the water demand gradually increased, and the watering interval gradually shortened. Basically, 5-7 times of shallow water in the whole growth period. The first three waters are watered every 10 days or so, and the interval from the fourth water is 6-7 days. Keep the soil moist and control the shallow water before harvest.
4. Disease control: the disease of coriander is less. Because it is open field planting, and now is the high incidence period of insect pests, vegetable farmers should focus on the prevention of insect pests. They can use 0.5% Emamectin salt 4000 times solution or 2.5% Caixi suspension agent 1000 times solution for prevention, once every 5-7 days.
Open field planting and greenhouse planting: open field planting method of coriander:
It can be cultivated in open field in spring, autumn and winter. When planting, pay attention not to water too much at the seedling stage. When the seedling grows to 10 cm, the plant will grow vigorously. Water frequently to keep the soil surface moist, and topdressing with available nitrogen fertilizer once or twice at the same time. In summer, it is necessary to shade properly, prevent rainstorm erosion, and drain water in time after rain to ensure orderly emergence.
The cultivation methods of coriander in greenhouse are as follows
Generally, direct seeding is conducted from September to October, and the seedlings are irrigated with frozen water once before winter. When the seedlings turn green, they are ploughed, loosened and weeded. When the height of the seedlings was 10 cm, the plants entered the vigorous growth period, and the temperature in the greenhouse was maintained at 15 ℃ to 25 ℃. It can be harvested in advance by applying about 15kg ammonium sulfate per mu once or twice.
In fact, it is not difficult to grow coriander in the greenhouse. As long as you follow the correct planting method and spend some time on management, you can grow green coriander. When coriander grows to 15-20 cm, it can be harvested. When harvesting, you can choose larger plants and let the small coriander continue to grow for a period of time. However, after harvesting, you should remember to fertilize the small coriander again in time, which will be more conducive to the growth of coriander.
In this paper, the introduction of coriander planting methods and techniques is here, for your reference, I hope to help you.
