Now, it is time for growing vegetables such as eggplant, tomatoes and celery in the autumn. When vegetables are raised in the summer, they often encounter adverse weather such as high temperature, drought, heavy rain, etc. Vegetable seedlings are prone to malformed seedlings and infections. So, how to raise good seedlings in the summer?
First, select plots
In summer, the seedlings should be selected for high dryness, good soil permeability and water retention, and they should be drained by heavy rain and encountered drought-watered land. Do not plant seedlings on the land that had been planted with the same vegetable in order to avoid the harm of soil-borne diseases, and avoid serious land-use breeding of soil pests.
Second, prevent high temperatures
Under high temperature conditions, many vegetable seeds tend to have different degrees of difficulty in germination. Soak the seed for 8 hours, then wrap it in a wet gauze and place it in a cold place to germinate. Treating at a low temperature of 2°C to 5°C for 48 hours can promote germination and increase the germination rate. Spread some short wheat straw or straw on the nursery bed, or cover the seedbed with a shade net. You can also use a shade shelter to cover old films, non-woven fabrics, bamboo curtains, curtains, etc., or raise seedlings under tall crops.
Third, disease prevention and pest control
Solanaceous vegetable seedlings often suffer from damping-off, blight, virus disease, gray mold, etc., pests are aphids, whitefly, cockroaches and so on. In the early stage of seedling emergence, 75% chlorothalonil 1000 times solution or 65% mancozeb manganese 1000 times solution can be sprayed, sprayed once every 7-10 days, and sprayed twice. If aphids or whitefly are found, they can be sprayed with agents such as beta-cypermethrin. For earthworms such as cockroaches, cockroaches, and wireworms, phlophosone drugs can be used to kill them.
Fourth, to prevent leggy
In the high temperature season seedlings, vegetable seedlings are prone to leggy, in the morning and evening with a watering can sprinkle water cooling, timely seedlings or seedlings, so that the seedlings of the nutritional area is larger. For fruits and vegetables such as cucumbers, tomatoes, etc., the seedlings can be controlled by spraying CCC. The seedlings are thick, the leaves are dark green, and the leaves are thickened, which promotes the differentiation of flower buds and can increase the seedling rate.
