After the spring sorghum vegetables enter the fruiting period, if the deformed flowers are more, the quality of the vegetables is poor and the price is not high. The main cause of malformed vegetables in spring sorghum is poor flower bud differentiation, and vegetables generally undergo flower bud differentiation from three leaves. Therefore, after planting the spring sorghum vegetables, it is necessary to cultivate strong trees to ensure that their flower buds are normal.
First, the regulation of shed warm and rapid seedlings
After the vegetable is planted, in order to promote its rapid seedling, the temperature in the shed is relatively high. In general, the daytime temperature is controlled at 25 to 30 °C, and the nighttime temperature is controlled at 15 to 20 °C. When the temperature in the shed exceeds 32 °C, pay attention to the opening of the air, but pay attention to the division to avoid drastic changes in temperature.
Second, strengthen fertilizer, water temperature management
After the vegetables are slowed down, it is necessary to gradually increase the amount of air released, and reduce the temperature in the shed. Watering and fertilization are generally not carried out during this time. If the soil in the shed needs to be watered, it is necessary to pour small water and avoid flooding. In principle, no fertilizer is required for half a month after planting. The temperature management of vegetables after slow seedling can be maintained at 25 ~ 30 ° C during the day and 10 ~ 15 ° C during the night.
Third, strong root disease prevention
After the vegetables are slowed down, they are eager to cover the mulch. It is necessary to strengthen the slashing work, increase the soil permeability and promote root development. In order to prevent dead seedlings and root diseases, the roots can be irrigated once with a 600 times solution of Plex and 800 times of Jinlei.
