What to pay attention to in spring cultivation of zucchini

Zucchini likes slightly acidic soil, so it is necessary to choose zucchini varieties that are disease-resistant, high-yield, high-quality, and have good appearance and shape. Suitable for production of strong seedlings, generally about 30 days old, with 3 to 4 true leaves, plant height about 10 cm, stem thickness about 0.5 cm, petiole length equal to leaf length, leaf color dark green, and cotyledons intact , Developed root system.

Before seed soaking and accelerating germination, the zucchini seeds should be dried in the sun for 2 to 3 hours, and then put into clear water, and the seeds floating on the water surface with insufficient grains should be removed and removed. Then soak the seeds with warm water at 55°C to 60°C for 10 minutes to further kill the pathogens on the seed epidermis. Then soak in warm water at about 25°C for 4 hours, remove it and control the moisture. Wrap it with damp gauze, and germinate at 28℃～32℃, and the seeds can be sown after they have broken their mouths and become white.

Regardless of whether it is using a seedbed to grow seedlings or a nutrient bowl, it is necessary to prepare a good nutrient soil first, which is the key to cultivating strong seedlings. Take three parts of fertile soil that has not been planted in melons within three or four years, one part of decomposed manure, add a small amount of plant ash and sawdust, mix well, sieve, and then make a border or a nutrient bowl. When ready, you can plant the seeds. After planting is completed, cover with two centimeters of soil. A small amount of bran mixed with organophosphorus pesticides can be sprinkled on the border surface to prevent underground pests. Then use a shed film to seal and moisturize until the seedlings emerge.

After emergence, temperature management should be strengthened. During the day, the temperature should be kept at about 20℃～25℃. If it exceeds 26℃, it should be ventilated and cooled. The temperature at night should be kept at 10℃～15℃, and the minimum temperature should not be lower than 6℃. At the same time, it is necessary to control the water. Only when there are obvious symptoms of lack of water can be watered. Do not water the big water. After watering, ventilate at the right time according to the weather and temperature, reduce the humidity, and prevent the occurrence of diseases.
