Why do vegetables cause rickets? How to prevent rickets?
Many vegetables are grown, and in the process of growing vegetables, various diseases, such as rickets, often occur. So how do we prevent and cure the disease of vegetables? Let's take a look at how to prevent and cure the disease. First, the ins and outs of the disease 1. Tripping disease is an important disease in the vegetable seedling stage, which can cause serious death. It mainly occurs on seedlings such as cucumber, tomato, eggplant, pepper, celery, onion, lettuce and cabbage, and the seedlings of Solanaceae and Melon are the most important. 2. Symptoms Most of the seedlings are susceptible to the disease from the base of the stem. They are initially water-stained and spread quickly. The contracture becomes thin like a "line". The diseased part does not change color or is yellowish brown, and the cotyledons are still green. The disease develops rapidly and sticks to the bed surface from the base of the stem before wilting. When the seedbed bed has a high humidity, a layer of flocculent white mold can be produced on the bed soil around the sick plant. 3. The seeds are infected before emergence, causing the cotyledons, young roots and young stems to become brown and rot, resulting in rotten buds. The disease begins with the onset of individual seedlings. When the conditions are suitable, the central diseased plant spreads rapidly around and forms a ward. It is mainly transmitted by means of rainwater, sprinkler irrigation, etc. Organic fertilizers and agricultural tools with bacteria can also transmit diseases. After watering, water or film drip is the most susceptible to becoming a central disease. Insufficient light, sowed too much, and the seedlings tend to be heavy when they are long. Second, the prevention and treatment of squatting disease (1) The seedbed chooses a plot with high dryness, shelter from the wind, and loose and fertile land, and uses decomposed high-quality fertilizer. (2) Strengthen seedling management, seedling in early spring, the temperature of the seedbed is not lower than 15 °C, and the air humidity is below 85%. (3) Seed disinfection, mixed with 0.5 to 1 g of 99% carbendazim soluble powder and 4 g of 80% poly-fusible zinc wettable powder per kg of seed. (4) disinfection of seedbed, use 0.5~1g of 99% carbendazim soluble powder and 4g of 80% Dover·zinc wettable powder per square meter, mix well with fine soil 20kg and take 1/3 to smash Face, the remaining 2 / 3 planted after the cover. Or use 99% carbendazim soluble powder, 1 to 2 grams per square meter of seedbed, 3 kilograms of water sprayed with water. (5) Prevention and control of seedlings. The diseased plants were immediately removed in the field, and evenly sprinkled on the seedbed with the above-mentioned herbs, and the spray or rooting of the 99% carbendazim soluble powder 3000-5000 times solution was also used. 2 to 3 days before transplanting, apply another medicine for better control. The above is about the introduction of vegetable collapse disease. For the disease, it is still very harmful to vegetables. Therefore, we still need to take precautionary measures. This is also to ensure the high yield and quality of vegetables. Can help the majority of vegetable growers.
