The latest points for attention in planting bitter chrysanthemum

Kuju, also known as bitter lettuce, is an annual or biennial herb, like cold environment, can be fried or cold, is a food to clear heat, but also has antibacterial, antipyretic, anti-inflammatory, eyesight and other effects, widely praised. Planting area is also more and more wide, so what should we pay attention to when planting bitter chrysanthemum? Let's get to know each other.

1. Selection of land

Before artificial planting, we must first understand its growth habits and characteristics, in order to plant well, bitter chrysanthemum generally likes to live in a cool environment, not resistant to drought, relatively cold and cold, like loose soil, rich in organic matter, and live better in acidic soil. We can choose a suitable place to plant according to the above characteristics, and then carry out tillage and fine cultivation, and apply some decomposed organic fertilizer as base fertilizer according to the soil fertility status.

2. Sowing

When sowing, we should choose seeds with certain disease resistance and stability. Since the seeds of bitter chrysanthemum are relatively small, we can adopt the method of sowing when sowing. Dig some shallow furrows on the ridge surface, sprinkle the seeds evenly into the furrows, cover the soil 1 cm thick, gently press with your hands, and then you can water it. The first watering must be thoroughly watered, so as to ensure the normal development of seeds. Sowing is generally about 2 kg per mu, so that it can avoid over-sparse or over-dense situations.

3. Watering and fertilizing

After sowing, it is necessary to water it in time, and then water it according to the dry and wet conditions of the soil. If it has been in rainy weather, it is necessary to reduce the number of watering times. If there is no watering for a period of time, it is necessary to water it immediately, so as to avoid water shortage affecting its taste and reducing income. In 4-5 days after sowing, the seedlings can emerge. At this time, field engineering should be done well. In addition to paying attention to the dry and wet conditions of the soil, proper fertilization should be carried out. Organic fertilizer can be applied at seedling stage. In the process of seedling growth, fertilizer should be supplemented as nutrients in time to avoid poor plant growth and yield decline.

4. Diseases and pests

Chrysanthemum is watered during its growth, but some common pests and diseases, such as downy mildew, virus disease and aphids, can occur if it is not properly managed. For downy mildew prevention and control, we should strengthen management first, water and fertilize reasonably, drain water in time in rainy days, avoid changes caused by accumulated water in the field, and spray control with Keluke and Saifu when the disease occurs. Virus disease can be effectively killed by seed dressing method when sowing, and at the same time, attention should be paid to watering, spraying virus A, chlorothalonil and Zhibingling emulsion for prevention and control. Aphids can be sprayed with aphid star, dimethoate, anti-aphid, methrin and other chemicals alternately to prevent drug resistance.
