How to raise seedlings of zucchini in winter

Zucchini is a very common vegetable on our daily table. Zucchini is also welcomed by many people because of its delicious taste and high nutritional value. So now there are a lot of people growing zucchini, and with the technology becoming more and more mature, it is now possible to grow zucchini in winter. So how to raise zucchini seedlings in winter? The following editor brings you the zucchini winter seedling technology, let's have a look!

1. Soil preparation and fertilization

Zucchini like to grow in slightly acidic soil, suitable for growth of soil PH value is generally around 6. Zucchini has a strong ability to absorb fertilizer, so we should pay attention to the amount of nitrogen fertilizer, not too much, otherwise zucchini is easy to grow. This leads to the phenomenon of falling flowers and fruits, and even diseases. When applying fertilizer, we should pay attention to the rational preparation of nitrogen, phosphorus and potassium fertilizer. Then we should do a good job of soil preparation to maintain a soft soil and improve the permeability of the soil. Promote the growth of zucchini root and improve the success rate of raising seedlings in winter.

2. Soaking seeds to accelerate germination

The temperature in winter is very low, so we should also do a good job of soaking and accelerating the germination of zucchini seeds. First of all, put the seeds in clean water and fish out the dried and immature seeds. Then wash it again and soak the seeds in warm water of about 60 degrees for about 10 minutes. Eliminate the pathogenic substances on the dead seed coat. Then soak the seeds in 25 degrees water for about 4 hours, remove them and dry them. Then wrap it with wet gauze and put it in a 30-degree environment to accelerate germination. When most of the seeds are white, they can be sown.

3. Sowing and raising seedlings

When raising zucchini seedlings, whether it is a seedling bed or a nutrition bowl. We'd better prepare the nutritious soil first, which is also the key measure to ensure the cultivation of strong seedlings. Take the garden soil that has not planted melons in three years, combined with rotten ring fertilizer, and then add the right amount of plant ash. Mix it evenly and sift it, then rebuild the bed or put it into a nutrition bowl. When you are ready, you can sow the seeds and cover about two centimeters of fine soil after sowing. Then sprinkle appropriate amount of methamidophos wheat bran on the border surface for pest control, and then use the small arch shed film to keep warm and moisturize until seedling emergence.

4. Temperature management of seedlings

The temperature in winter is very low, so temperature management in the seedling stage is very important. After emergence, the daytime temperature should be kept at about 22 degrees, not more than 25 degrees. If the temperature exceeds, it should be cooled in time. At night, the temperature should be controlled at around 12, and the humidity should not be too high to avoid diseases. At the same time, we should also do a good job in the prevention and control of diseases and insect pests, such as methyl thiophanate and chlorothalonil. Ensure that the seedlings thrive and avoid some unnecessary losses.

The above is a brief introduction to the winter seedling technology of zucchini. That's all for today's introduction. This article is for reference only. I hope it can help you all.
