After the spring oyster vegetables have entered the result period, there will be more malformed flowers, poor quality of vegetables, and high prices. The main reason is the poor flower bud differentiation, and the vegetables generally begin flower bud differentiation from three leaves. Therefore, after the planting of spring eel vegetables, we must take sufficient measures to cultivate strong trees and ensure their normal flower bud differentiation.
The first is to regulate the environment of the greenhouse and promote its rapid seedling growth. After the planting of vegetables, in order to promote rapid easing of seedlings, the temperature in the shed is required to be relatively high. In general, the daytime temperature is controlled at 26°C-32°C, and the nighttime temperature is controlled at 15°C-20°C. When the temperature in the shed exceeds 32°C, the bleed outlet on the shed must be opened, but care must be taken to ensure that the temperature changes drastically.
The second is to pay attention to appropriate seedlings. After the vegetables are seedlings, pay attention to fertilizer and water, temperature management, and appropriate seedlings. After easing the seedlings, the air release should be gradually increased to reduce the temperature in the shed, which can be maintained at 25°C-30°C during the day and 13°C-15°C at night. In addition, watering and fertilization are generally not performed during this period of time. If the soil in the greenhouse needs watering, it is necessary to pour small water and avoid flooding. Half a month after planting, no fertilizer application is required in principle. When growth is weak, fertilization with antibacterial 968 seedlings and Apollo 963 root-raising element can be applied to promote root development and meet crop growth requirements.
The third is to root and prevent disease. After easing the vegetables, they are eager to cover the mulch. It is necessary to intensify the ploughing work, increase the permeability of the soil and promote the development of the root system. In order to prevent dead trees, it is better to pour root defense root canal with Puerix 600 times liquid and gold mine 800 times after scratching.
