In autumn, vegetables are extremely vulnerable to pests and diseases, and cultivation management becomes more difficult. The "three-strength" management should be adopted to achieve high-quality, high-yield and high-efficiency vegetables.
Fertilizer and water management At present, vegetables are in a critical period of growth, and some have entered the harvest period. At this time, fertilizer and water management should be strengthened. Fertilization should follow the principle of “apply more organic fertilizers and less chemical fertilizersâ€. The top dressing of leafy vegetables (such as cabbage, celery, etc.) should be mainly nitrogen and calcium fertilizers, supplemented by potassium fertilizers, phosphate fertilizers, and some medium and trace elements (calcium , Zinc, magnesium, etc.), combined with certain foliar fertilizers (potassium dihydrogen phosphate, etc.); fruits and vegetables (such as watermelon, wax gourd, tomatoes, etc.) should be based on phosphorus and potassium fertilizer, supplemented by nitrogen fertilizer, and add some medium, Application of trace element fertilizers; root vegetables (such as carrots and white radishes) are mainly potassium fertilizer, supplemented by phosphate fertilizer and medium and trace element fertilizers. Watering and drainage should be proper. In drought, pay attention to strengthen watering and small water frequently to keep it dry and wet; when precipitation is large, pay attention to drainage and dig drainage ditches. In particular, root vegetables and melon vegetables are greatly affected, and standing water can easily cause diseases such as retting and rot. At the same time, after heavy rain (under good drainage), water from the well can be used to cool the ground. Watering can be combined with fertilization.
For field management and weeding, we must often cultivating and weeding, and the loose soil should not be too deep to avoid root damage. Try not to use herbicides, which have a greater impact on the growth of vegetables. Ridging and ridge cultivating. For ridged vegetables (such as cabbage, green onions) that are damaged by rainfall or watering, ridges should be cultivated in time. Vegetables that have not had time to ridge should be ridged in time according to the actual conditions of vegetable growth to make drainage smooth , No water accumulation, reduce disease. Plant arrangement: For racking vegetables (such as cucumbers, beans, tomatoes, etc.), timely plant arrangement (breaking branches, picking old leaves, diseased leaves) should be carried out to facilitate ventilation, light transmission, and increase fruit setting rate. The outer leaves of the plant cannot be thinned, but the inner leaves should be thinned to increase the air permeability in the plant. It should be noted that after trimming, wiping branches, and thinning leaves, the fruits often suffer from sunburn due to sudden exposure to the sun. For pumpkins and other vine-growing vegetables, the vines should be reasonable, and the control group should not be too large to help enhance disease resistance.
Diseases and insect pests control Vegetables mainly occur fusarium wilt, virus disease, soft rot, downy mildew, root rot, powdery mildew, bean borer, aphids, etc., as well as some physiological diseases such as fruit cracking, fruit dropping, and poor growth. Vegetable farmers should adhere to the principle of "prevention first and treatment second" and advocate the use of biological pesticides.

- Dietary fiber
- Other specific nutrients, such as Amino Acids, enzymes, probiotics, plant extracts, etc
The purpose of nutritional supplements is to meet the nutritional deficiencies that individuals may have due to special needs, dietary habits, digestive and absorption problems, health conditions (such as disease, pregnancy, aging, etc.) or other reasons. They are usually available in the form of tablets, capsules, oral liquids, powders, etc.
When choosing a nutritional supplement, one should consider an individual's physical condition, diet, and possible side effects. Although nutritional supplements can provide additional nutrients, it does not mean that they are a substitute for a balanced diet. The best strategy is usually to get most of your nutrients through a varied diet and use nutritional supplements when necessary under the guidance of a medical or professional.
