1, epidemic
Coffee Huang Kui can be infected at seedling stage and adult stage. When the seedling grows to 20 cm, the blight spreads from the leaves to the main stem, making the stem thinner and faded until the whole plant withers or knocks down. The diseases of leaves mostly start from the tips or green leaves at the lower part of plants. At the beginning of the disease, it was dark green, waterlogged and amorphous, and turned brown after expansion.
Prevention and treatment: Spraying 72% Mn-Zn, cymoxanil WP (500 times) or 69% Anke Mn-Zn WP900 times or 64% antivirus alum WP400 times or 58% metalaxyl and Mn-Zn WP500 times 7- 10/times every 7-/0 days at the beginning of the disease for prevention and treatment for 2-3 times.
2. Virus disease
Coffee Huang Kui virus disease is the main disease in okra production, and the adult stage is more serious than the seedling stage. The whole plant suffers from this disease, especially the tender leaves at the top, which show mosaic or brown markings. Early infection, low plant strength, little or no fruit.
Prevention and control measures: No seeds are left in the diseased fields, and disease-resistant varieties are selected. At the initial stage of the disease, 5% bacterial toxin WP400-500 times or 20% virus AWP400 times or 1000 times or 83% resistance enhancer 100 times are used for prevention and control, and the interval is 7- 100 times.
insect pest
1, poisonous caterpillar
Coffee Huang Kui mainly harms the seedling stage. After emergence, they often feed on mesophyll and leave veins in severe cases. Control: spray with 10% EC 1500 times solution or 5% ruiqiang SC 1500 times solution or avermectin EC+ fenvalerate EC3000 times solution.
2. Liriomyza sativae
Coffee can be damaged in the whole growth period in Huang Kui, mainly by leaves, and it can be controlled by 1.8% avermectin EC 5000 times, 52.25% agrotianle EC 1000 times, 48% Leben EC 1000 times or 5% Regent SC800 times.
3. Aphids
Coffee can occur in Huang Kui during the whole growth period, especially in the adult stage. Imidacloprid pesticides such as 10% once cleaning, 10% aphid and lice cleaning, 10% Dagong, etc. Can be used for 3000 times.
4. ants
After coffee Huang Kui blooms, ants often gather on the flower organs to cause harm. Use 48% Lebenben EC 1000 times solution spray or 5% Regent EC 1500 times solution spray or use Regent 0.3% liquid medicine mixed with sawdust to trap and kill ants.
The coffee harvest interval in Huang Kui is short, so the pesticides used must be suitable for pollution-free vegetables, and should not be sprayed on flowers or fresh fruits.

Growth habit
1, temperature
Coffee Huang Kui likes warmth, is afraid of cold and has strong heat resistance. When the air temperature is 65438 03℃ and the ground temperature is about 65438 05℃, the seeds can germinate. But the optimum temperature for seed germination and growth period is 25-30℃. The monthly average temperature is lower than 17℃, which affects flowering and fruiting; When the night temperature is lower than 14℃, the growth is slow, the plants are short, the leaves are narrow, the flowers are few and the flowers are many. At 26-28℃, there are many flowers, high fruit setting rate and fast fruit development.
Step 2: Moisture
Huang Kui coffee is drought-tolerant and moisture-tolerant, but not waterlogged. Excessive soil moisture in germination stage is easy to induce seedling blight. The fruit period is dry, the plant growth is poor, and the quality is poor. It is necessary to keep the soil moist at all times.
3. Lighting equipment
Huang Kui coffee is particularly sensitive to light conditions, which requires a long light time and sufficient light. Choose sunny plots, strengthen ventilation, pay attention to reasonable close planting, and avoid mutual shading, which will affect ventilation and light transmission.
Nutritional value of okra
1, okra is rich in vitamins and minerals. Every100g of tender fruit of okra contains about 4mg of vitamin C, 0/.03mg of vitamin E/kloc-0 and 0/0μ g of carotene. Okra is rich in trace elements such as zinc and selenium, which is very helpful to enhance the anti-cancer ability of human body.
2. There is a viscous liquid substance in the fresh fruit of okra, which contains polysaccharides such as pectin and mucopolysaccharide. Mucopolysaccharide can enhance the body's resistance, maintain the smoothness of articular membrane and serosa in human joint cavity, reduce the accumulation of lipid substances in arterial wall and avoid the atrophy of liver and kidney connective tissue.
