1、 Curing method

1. Soil: This is a kind of wild vegetable that is well cultivated. It often grows on sandy soil. Because its soil is loose and fertile, it is very suitable for cultivating bitter vegetables

2. Moisture: the amount of water should be appropriate when watering. Too much water will affect the growth of its roots due to too low temperature. If it is too small, it will grow too small because of insufficient water. Therefore, when watering, it is necessary to carefully investigate the amount of water. Usually, the land becomes wet

3. Fertilizer is mainly used to fertilize the leaves and stems of bitter vegetables, so as to increase the yield of leaves and stems

4. Light: it is not suitable for direct irradiation of strong light, because it likes a cool environment, shade is very necessary, and astigmatism irradiation is more conducive to the growth needs of bitter vegetables

2、 Breeding skills

1. Pruning: generally, the weeds in the field need to be pruned for breeding bitter vegetables. Because they grow small and almost the size of weeds, blind weeding will hurt bitter vegetables. Generally, we wait until the weeds grow to a certain size and choose the method of manual weeding to solve it

2. Reproduction: sowing method is often used to reproduce. Before sowing, the soil should be watered first, and then the seeds should be sprinkled in the soil and buried shallow after water infiltration. In about a week, seedlings can grow and keep the soil moist and loose

3、 Problem diagnosis and treatment

1. Downy mildew: the common disease of cultivated bitter vegetables is downy mildew. Downy mildew should be treated in time, otherwise it will infect other robust stems and leaves. Dilute it with chlorothalonil and water and spray it on its stems and leaves. The effect can be achieved in about a week

2. Rotten roots: there are many reasons for rotten roots. One is that the rotten roots are caused by underground pests biting their roots, which can be diluted and sprayed with imidacloprid mixed with water. One is because the water volume is too large during irrigation, and there is ponding stored at the root, which will cause the occurrence of rotten roots. Just pay attention to two points

4、 Other issues

1. How to spend the winter: in order to prevent it from being injured by cold, a greenhouse should be built for it before winter, and the temperature should be controlled at about 10-15 degrees Celsius, so that it can grow normally in winter

2. Edible or not: bitter vegetables are edible, cold and fried. They are cultivated in many areas of China and are also one of the more common vegetables
