Cultivating strong seedlings is an important measure for delaying the planting of vegetables in autumn. But in the process of the reporter’s recent trip to the countryside, he found that some vegetable farmers did not do well in this area: Many greenhouse vegetables were slowed down after planting, and trees were never released. On the contrary, some greenhouse vegetables grow quickly after they are planted, so that their nutrition grows too strong and their trees grow. Both of these conditions are very worrying, because whether it is weak or leggy will affect the increase in vegetable production and efficiency. Therefore, after delaying the colonization of vegetables in autumn, we must regulate the growth of plants and cultivate strong seedlings so as to lay a good foundation for increasing production and increasing income. So, how to regulate the growth of vegetables that have just been planted? The author believes that it is necessary to "promote" and "squeak" first: First, "promote" into the slow seedlings. After planting vegetables, the first task is to urge them to ease seedlings as soon as possible. There are three measures: First, pay attention to shade and cool down. The temperature in autumn is still high, especially at noon on sunny days. High temperature and strong light often cause the vegetables in the slow seedling stage to lose water and wilt, or even die. Therefore, the shading net must be set up during this period to prevent the seedlings just planted from being harmed by high temperature and strong light; the second is to pay attention to moisturizing. The high soil and air humidity are required for the seedlings of the vegetables to ensure their survival rate. During this period, due to the hot weather, soil water disperses quickly, and the newly planted seedlings are vulnerable to wilting and dead seedlings due to insufficient water supply. Therefore, after the vegetables are planted, they must be watered in a timely manner. Note that the amount of watering should not be too large to prevent vegetables from picking up roots; After each water is poured, it must be timely scratched in order to increase the permeability of the soil and promote the early deepening of the root system. Fourth, prevent dead seedlings. Vegetables are most prone to dead seedlings at the seedling stage and should be prevented in advance. Miao Bao can be used, anti-bacterial 968, Dien microbial agents, green cattle black liquid fertilizer and other microbial preparations to root. It is also possible to irrigate roots with 600-fold solution of Prokary or 1000-fold solution of methyl-r-tocopherol, but pay attention to the use of fungicides and biological agents. Do not use them simultaneously. Second, "cockroach" strong seedlings. After the vegetables have grown slowly, their growth is accelerating. Without control at this time, it's easy to be prolonged. Therefore, the vegetables must pay attention to the growth of the seedlings after the easing of seedlings until the result. Seedling measures should pay attention to the following three points: First, pay attention to temperature control. The long-term temperature in the shed is too high, and the plants are easy to grow long. Therefore, attention should be paid to strengthening the ventilation and setting up the shade net to reduce the temperature in the shed so that the daytime temperature does not exceed 30°C; the second is to control the water and fertilizer. After the slow recovery of vegetables to grow, it should pay attention to controlling water and fertilizer to prevent sufficient fertilizer and water, and the plants are long. Under normal circumstances, because the base fertilizer has been fully applied, there is no need to top-dressing in this period, but the watering should be strictly controlled, and the amount of watering and watering times should be reduced as much as possible to avoid excessive watering and excessive plant length; the fourth is strong spray. Su. For severe plant growth, 1500-fold booster and 3,000-fold increase in spray strength can be used to control the growth potential.
