One avoids the blind period in advance. Solanum vegetables in spring plastic greenhouse cultivation, winter nursery time should be appropriate, peppers, eggplants around mid-October, loofah, cucumber around mid-January, some vegetable farmers mistakenly believe that early sowing can result, morning market, and thus blind early sowing As a result, the seedling stage is too long, the living tree is slow when transplanting, and the falling flowers are seriously.
The second bogey soil is reused. Many vegetable farmers do not pay attention to changing the soil of the seedbed, and repeatedly use it, resulting in the accumulation of soil germs and the disease at the seedling stage.
The three bogey seeds are not treated directly for seeding. Some vegetable farmers have insufficient understanding of the importance of seed treatment. They do not directly sown seeds, such as disinfection, soaking, germination, etc., resulting in prolonged emergence and untidy emergence.
Four bogey temperature control is improper. The temperature management of the seedling bed after the seedlings should not be too high. In principle, it should be lower than about 5 °C before emergence, so that the seedlings grow robustly and enhance the cold resistance and disease resistance. Attention should be paid to the "two leaves and two hearts" period, while avoiding high temperature affecting flower bud differentiation. At noon on a sunny day, the temperature of the seedbed is easily high, and the film should be peeled off at both ends. Cover the membrane insulation after 3-4 pm.
The five bogey beds are too humid. At the seedling stage (especially during the wintering stage), the seedbed is not exposed to white water and water is not sprinkled. When watering must be done, it should also be chosen in sunny afternoons.
Six bogey seedlings see insufficient light. During the wintering period of the seedlings, it often encounters rainy and snowy weather. At this time, the outside temperature is low, the light is insufficient, and the seedling development is affected by malnutrition. Artificial light supplementation measures should be taken in time to enhance the illumination.
Seven bogey ignore disease prevention. Due to factors such as low temperature, weak light, and high humidity during seedling stage, diseases should be prevented and prevented in time to reduce disease occurrence and reduce losses.
Eight bogey will not be refining the seedlings will be planted. 5-7 days before planting, the seedlings should have a refining process to enhance the seedling resistance, adapt to the environment after planting, and avoid direct planting without refining.
