Planting vegetables with slight cold and solar terms, and doing well the seedling management of early spring crops.

Tomorrow is the annual slight cold solar term. For vegetable farmers, the temperature is low, the sunshine is less, and the strong cold air is frequent in the slight cold season. It is necessary to do a good job in seedling management of early spring crops to ensure the healthy growth of crops in this cold period. Let me introduce you.

It is very important to cultivate healthy seedlings of appropriate age. Strong seedlings are the basis of high quality and high yield. During the slight cold period, the temperature is low, the light is weak and the sunshine time is short. Therefore, raising the temperature, keeping the temperature and increasing the light are the keys to the success or failure of seedlings. Nursery shed should be selected in a solar greenhouse with good lighting conditions and good thermal insulation effect. Before nursery, a ground hotline should be laid, and supplementary light can be installed if conditions permit.

Generally, tomato seedlings take 5060 days, eggplant takes 6070 days and cucumber takes 4050 days. Tomato and eggplant are cultivated in 50-hole or 72-hole hole trays; Cucumber seedlings are cultivated in 32-hole or 50-hole trays, or 8? 8 cm nutrition pot seedlings.

Choose a good quality brand-name nursery substrate, or use peat nutrient soil and vermiculite to prepare the substrate according to the ratio of 2: 1, and add nitrogen, phosphorus and potassium ternary compound fertilizer 10 kg per cubic meter. Do a good job of soaking seeds to accelerate germination and chemical treatment, and choose sunny days for sowing, so as to achieve uniform sowing and uniform covering thickness.

Key period of warm-loving vegetable management in winter stubble

The slight cold solar term is the key period for the management of warm-loving vegetables in tomato and cucumber winter stubble. Pay attention to the weather changes to prevent crops from being damaged by strong cold current and cloudy days, and take temporary heating measures such as yuba, heating burning block or electric stove when necessary.
