Summer and autumn vegetables have a larger range of cultivation, and many varieties are planted. When vegetables are grown in summer and autumn, it is necessary to prevent the harm caused by high temperature on vegetable seedlings.
First, pay attention to shade
Shading is an important work for summer vegetable seedlings. The sun is fierce in summer and autumn. If proper shading is not carried out, it will easily cause the soil temperature to rise, the water to evaporate too quickly, and the seeds will not be able to grow out of the seedlings or the emergence rate will be reduced. When the shading is over, a simple arch canopy can be built, shade nets can be covered on the arch cover to shade, and the shade nets can be removed according to actual conditions after emergence.
Second, planting pot should cover moisturizer
After sowing, the seedlings should be kept moist before the soil is broken. For some fields that are inconvenient to shading with shade nets, it is possible to cover the surface of the seedlings in a suitable way. effect.
Third, prevent the heat from generating long
Due to the high temperatures in summer and autumn, the seedlings are extremely prone to growth, especially tomato seedlings are more susceptible to longevity. In order to cultivate strong seedlings, paclobutrazol or chlormequat solution may be sprayed on seedlings to 2 or 3 true leaves to control the seedlings' leggy. When they grow to 5 to 8 true leaves, they can be sprayed once more.

Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
