Chess is a high-nutrition vegetable rich in more than 20 nutrients such as protein, carbohydrate, dietary fiber, vitamins, calcium, phosphorus, iron and sodium. The protein and phosphorus content is 1 times higher than that of melons, and the iron content is 20 times more than that of tomatoes. So how is summer celery? The following small series talk about the cultivation techniques of summer celery. First, summer celery cultivation technology Variety selection Cultivation of summer celery, more choices of heat-resistant, disease-resistant varieties, such as green celery celery, Jinnan real celery, glass crisp celery. These varieties have fewer petiole fibers, grow faster, are less prone to aging, and have good quality. It is usually planted in stages from May to June and harvested from August to October. 2. Cultivation methods and soil preparation and fertilization Summer celery is more live, and it can also be transplanted. For plots that cultivate summer celery, you should choose a land with high topography, convenient watering and drainage, good ventilation, and fertile soil. Before planting, it is necessary to apply enough base fertilizer, deep and flattened, high-pitched, narrow-necked, and wide 1.2-1.5 m wide. 3. Sowing of summer celery The temperature is already high, and the seedlings are usually released faster after soaking and germination. Wet sowing can be used, that is, water is first poured in the sputum, and then sown after water seepage. After sowing, the fine soil is covered with 0.5-1 cm thick; if the overburden is too thick, the young buds are difficult to excavate, and the seedlings are not prosperous after being unearthed. After entering the planting in June, the temperature is high, and there are many hot and dry winds. In order to reduce the ground temperature, after sowing the soil, the shading covers the shading net and other shades, creating a cool micro-climate, so that the emergence of seedlings is quick and emergence. The cover is removed after emergence. Depending on the weather and soil moisture, small and frequent pouring, keep the surface moist. Rainwater should be removed in time to prevent damage. It is also possible to use a small arch shed to cover the sunshade net before heavy rain, and to prevent the rain from scouring the surface and causing soil compaction. 4. Water and fertilizer management of summer celery After the celery grows 5-6 leaves, the growth is accelerated, and the management should be based on promotion, generally not seedlings. In the hot and dry season, the shade net should be covered to cool and moisturize, which is good for growth, fiber reduction and quality improvement. Topdressing should be based on a small number of principles, not too much for each application. Nitrogen fertilizer and decomposed light pig manure should be selected, and other organic fertilizers should not be applied. After the plant grows up, the top dressing can be combined with watering. In summer, the temperature is high, and it is necessary to keep the soil moist frequently, which is conducive to the vigorous growth of celery. Diseases and pests should be prevented in time. Stop pouring manure and spraying pesticides 10-15 days before harvesting. 5. Summer celery disease prevention and control The celery pests and diseases mainly include spot blight and spot disease, which can be controlled by using zinc, carbendazim or chlorothalonil. The main pests are aphids. Can be killed by enemy or dimethoate. 5. Harvesting According to the growth of celery and market demand, timely harvest. Generally, due to the high temperature and heat in the growing season of summer celery, it is not conducive to the growth of celery. Therefore, the harvest of summer celery is generally earlier than that of autumn celery, which is generally semi-annual. Second, the medicinal value of summer celery There are many pharmacologically active ingredients in the summer celery. The main active ingredients include flavonoids, volatile oil compounds, unsaturated fatty acids, chlorophyll, mushrooms, and coumarin derivatives. At present, the most researched and deepest researcher is apigenin, which has anti-tumor, anti-inflammatory, anti-oxidation, blood pressure-lowering and vasodilator effects. Celery also has the effect of calming liver and clearing away heat, removing wind and dampness, removing swelling and swelling, cooling blood to stop bleeding, detoxifying Xuanfei, strengthening stomach and blood, clearing intestines, relieving cough, lowering blood pressure and calming brain. Summer celery is rich in apigenin, which can dilate blood vessels and calm down. Take it directly with fresh celery juice or celery juice and honey with a little sugar to prevent high blood pressure. The high content of calcium and phosphorus in celery can enhance bone health. Celery has a high cellulose content and is digested to produce an antioxidant that inhibits intestinal bacteria. It can also speed up intestinal peristalsis, promote excretion, reduce the contact time between carcinogens and colonic mucosa, and prevent colon cancer. Celery is rich in potassium, which can prevent edema. Patients with edema should eat more fresh celery juice. Celery is rich in iron, which can often serve as an iron supplement. Celery contains substances that can neutralize uric acid. You can often eat fresh milk and cook celery to prevent gout. The above is the cultivation technique of Xia Qin, is it very simple?
