A Detailed Guide to the Latest Field Management Techniques for Curly Endive (Frisée)

Curly endive (frisée) is a biennial or annual herbaceous plant, mostly used in China for cold salads, soups and the like, and it is a fairly popular vegetable. The taste of curly endive carries a slight bitterness, and it has various benefits such as clearing heat and reducing internal fire, and reducing inflammation and improving eyesight. Its popularity is relatively high, and curly endive now has a certain amount of planting area. So how should it be managed when growing curly endive? Below, the editor brings you the field management techniques for curly endive. Let's take a look!

1. Cultivation and Weeding

Cultivation and weeding work is of great help to the growth of curly endive. First, after the curly endive seedlings emerge, field inspection work should be done well. If drought occurs, then watering should be done in time to avoid soil drought. Do a good job of loosening the soil to improve soil permeability and reduce the rate of water evaporation. Moreover, because the root growth capacity of curly endive seedlings is not strong and is fragile, when loosening the soil, attention should be paid to the force used to prevent excessive force from damaging the roots. This would affect the roots' absorption of water and nutrients, and attention should also be paid to doing a good job of weeding to prevent weeds from robbing the nutrients needed for the growth of curly endive.

2. Thinning and Replanting

After the curly endive seedlings emerge, the growth of the seedlings should be observed frequently. Some seedlings with weak growth and pests or diseases should be pulled out in time to avoid affecting the overall growth. When the seedlings grow to a certain size, do a good job of thinning and final singling to provide sufficient growing space for the robustly growing seedlings. Then, robustly growing seedlings should be replanted in the holes left by pulling out the others, ensuring the full-stand rate and yield of curly endive. After the thinning work is done, the pulled-out weak seedlings, dead seedlings and other seedlings should be taken out of the field together with the weeds and burned to avoid carrying pathogens.

3. Water and Fertilizer Management

Water and fertilizer work is something to pay special attention to when growing curly endive. Because water and nutrients are the key to ensuring the healthy growth of curly endive, we should water and fertilize reasonably according to the growth of curly endive and natural environmental factors such as soil and weather. During the seedling stage of curly endive, keeping the soil evenly dry and wet is sufficient; too much watering will cause curly endive to grow leggy. Too little, on the other hand, will cause the seedlings to decline prematurely and affect growth. During the vigorous growth period of curly endive, the soil should be kept in a moist state; otherwise, too little water will increase the bitter elements of curly endive and reduce its commercial value. Then, fertilizer should be applied appropriately according to the growth of the curly endive plants. Generally, the base fertilizer is mainly farmyard manure, and the topdressing is mainly compound fertilizer and micro-fertilizer.

4. Pest and Disease Control

Pest and disease control is management work that we need to focus on doing well when growing every kind of crop. Because if curly endive develops pests or diseases, it will certainly lead to losses. In severe cases, it is even possible to cause total crop failure of curly endive. Therefore, we should pay attention to doing a good job of disinfection, strictly disinfecting seeds and soil before planting to reduce the pathogen base. Then, during the growing process, use disinfectants reasonably to inhibit the spread of pathogens. After curly endive becomes diseased, the specific cause should be identified in time, and then targeted control should be carried out to avoid the spread of the disease and affect the normal growth of curly endive.

The above is a brief introduction to the field management techniques for curly endive. These are not only management tasks we need to do well, but also some aspects we need to pay attention to in planting. Avoid unnecessary losses and protect your own planting benefits. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
