What should be paid attention to in raising pepper seedlings in summer and autumn? Please introduce pepper seedlings in summer and autumn. When pepper seedlings are easily affected by high temperature, rainy, drought and other weather factors, resulting in poor seedling quality, in order to cultivate high-quality strong seedlings in hot summer, experienced vegetable farmers put forward the following suggestions: first, choose a well-ventilated plot to prevent high temperature as a seedling bed and cover it with sunshade net. When 60% or 70% of the seedlings are unearthed after sowing, the mulch of the seedling bed is removed immediately, thus lowering the temperature of the seedling bed and creating a small environment suitable for seedling growth. Second, to prevent the harm of strong wind and rainstorm, choose the land with high terrain and good drainage, and the way of shading and cooling is best to use the method of "one net and one film" to cover the sunshade net on the film to cool down, but also can prevent the harm of rainstorm, pull down the plastic film before the rainstorm comes, and close the windproof outlet, fix the pressing film line, and prevent the strong wind. Pay attention to prevent the seedling bed from entering water, which will lead to the soil consolidation of the seedling bed, which is not conducive to seed germination and soil, resulting in a large number of dead seedlings. Third, determine the sowing amount according to the quality before anti-drought sowing, sow the seedling bed with sufficient bottom water, shade and moisturize after sowing, according to the weather conditions, spray water with a spray can in the morning or evening to prevent excessive drought. 4. The excessive growth of seedlings is due to insufficient light, weak photosynthesis, less nutrition, high temperature, especially high night temperature, strong respiration and high nutrition consumption, which reduces the dry matter in the plant, coupled with sufficient nitrogen fertilizer and water. Promote overgrowth; seedling bed sowing is too dense, mutual shading, no ventilation, less light at the bottom of the seedling, more light at the upper part will also lead to overgrowth. Measures: control nitrogen fertilizer and watering water, and timely chemical control, using Fengshou No.1 800 times spraying. Fifth, the prevention of diseases and insect pests is affected by high temperature, virus diseases, aphids, whitefly occur more, reducing the temperature of the seedling bed can effectively prevent virus diseases. Insect control nets and chemical control methods can be used for aphids and whitefly, and the concentration should not be too high so as not to damage the seedlings.
