Plastic seedling cultivation method of cucumber

Cucumber planting methods are mostly based on mulching plastic seedlings, which can effectively control the soil temperature and prevent the excessive evaporation of water to affect the growth of cucumber seedlings. It has a very good promotion effect on the quality and yield of cucumber. So how do we use plastic film to raise seedlings when planting cucumbers?

1. Seed treatment

First of all, we must choose high-quality cucumber seeds that are full, strong and wound-free. After selecting the seeds, we must pay attention to disinfection of the seeds. Because we cannot guarantee whether the seeds are completely free of pathogens, it is a necessary measure to reduce the incidence of diseases and insect pests. First, soak the dried seeds in warm water at about 60 degrees for about 10 minutes. Stir while soaking. When the water temperature drops to about 30 degrees, soak the seeds for about 5 hours, and then remove them for germination. Or you can use a solution such as carbendazim hydrochloric acid to soak the seeds for about one hour, then remove them and wash them in water for about 4 hours, then germinate.

2. Germination method

After the seeds are sterilized, the seeds must be germinated. After disinfection, the seeds must be cleaned first, the water on the seeds should be cleaned, and then wrapped with a damp cloth and placed in an environment of about 30 degrees for germination. When germinating, pay attention to turning the seeds frequently to ensure that the seeds are heated evenly. After about a day or so, the seeds will begin to germinate. When the seeds are exposed to the root tips, the temperature should be properly reduced and controlled at about 25 degrees, and the buds can be budded in two days. If the seeds cannot be sown after rainy days after germination, wrap the seeds with a wet towel and place them in a 10 degree environment to control the growth of young shoots, and then plant the seeds when the environment is suitable.

3. Sowing film

The soil should be selected before sowing. The best crops in the soil should be beans and vegetables. The soil layer remains soft, with sufficient fertility and normal drainage and irrigation. In the 2-3 weeks before planting, the soil is deeply ploughed, and then pay attention to the application of sufficient farm manure per mu, and the amount is kept at about 2500kg. After leveling and raking the soil, dig trenches to make field borders. In addition, it is necessary to intact the sowing hole, the depth of the hole should be kept at about 8 cm, and about 3 seeds per sowing hole. After sowing, the film should be covered in time. When the seedlings break the soil, the film should be properly cut to promote the refining of seedlings.

4. Water and fertilizer management

When the soil temperature is stable at about 15 degrees, the seedlings are thinned, and the strength is kept weak. The first top dressing is carried out three days after the seedlings, and then about 15 kg of urea is added after 10 days. After the cucumber penetrates the plastic film, the demand for water increases, so it is necessary to keep the soil moist in the early stage of planting. During the initial flowering period, water should be properly poured to promote root growth and improve the rate of sitting melons. About 5 days before harvest, increase the amount of fertilizer and water appropriately. The watering time should be kept about once a week. In the rainy season, we must pay attention to the drainage work to avoid decay caused by the accumulation of water.
