Matters needing attention in raising seedlings of zucchini

Zucchini is an annual vine. The origin of zucchini was originally in North America. After it spread to China, it immediately harvested a large number of "fans". Zucchini taste delicious, rich in water, vitamins and other substances, with thirst and diuresis, detumescence and moistening lungs and other effects. Zucchini is now widely planted in our country, but do you know what to pay attention to when raising zucchini seedlings? Let's take a look at it.

1. Soil preparation and fertilization

It must be necessary to prepare the soil before sowing. Zucchini is suitable to grow in acid soil, and the soil pH can be controlled at about 6. The root growth ability of zucchini is strong, and the rate of absorbing nutrients is relatively fast, so we should pay attention to the application of nitrogen fertilizer to prevent excessive nitrogen fertilizer from causing zucchini to grow, flowers and fruits to produce a variety of diseases and insect pests. When applying fertilizer, the proportion of nitrogen, phosphorus, potassium and other fertilizers should be reasonable, and the amount of fertilizer should be reasonably controlled according to the planting area and the number of results.

2. Soaking seeds to accelerate germination

Seed disinfection should be familiar to everyone. Before sowing, we should not only disinfect the seeds, but also do a good job of accelerating germination. First of all, soak the seeds in clean water and fish out the empty shell seeds that float on the water surface. Then the normal planting is soaked in warm water of about 60 degrees for 8-12 minutes to promote germination, in order to eliminate the bacteria lurking on the surface of the seeds. Then lower the temperature of the water by 30-40 degrees and soak for 3-4 hours. Finally, remove and air-dry the water on the seeds, wrap the seeds with gauze and soak them at a temperature of about 30 degrees to promote germination.

3. Sowing and raising seedlings

After the success of sprouting, it is necessary to carry out the work of raising seedlings, which is all the preparatory work before raising seedlings. Before raising seedlings, we should first prepare the nutritious soil, which directly determines the growth ability of the seedlings. Nutritious soil can be directly used in vegetable garden soil, but it should be noted that melons and vegetables have not been planted in the soil before, and then fully mixed with farm manure and firewood ash to make nutritious soil. After that, you can sow and raise seedlings. After sowing, keep warm and moisturize in a soil covering about two centimeters, then sprinkle an appropriate amount of methamidophos to prevent insect pests, and then cover the plastic film to know the emergence of seedlings.

4. Seedling management

After emergence to the zucchini seedling stage, the seedling stage to reasonably control the temperature, the daytime temperature can not exceed 25 degrees, if more than immediately do a good job of ventilation and cooling. The temperature at night can be controlled at about 12 degrees, with a minimum of 6 degrees. The second is the management of water, water should not be too much nor too little. Found that after the lack of water can be appropriate small water drip irrigation, after pouring water should also be timely ventilation, reduce the temperature, prevent the occurrence of diseases and insect pests. If there are diseases and insect pests, check what the diseases and insect pests are, and then use corresponding treatment measures to improve the survival rate of seedlings.

The above is a brief introduction to the matters needing attention when raising zucchini seedlings. The seedling stage of zucchini is very important. If it is not managed properly, it will increase the incidence of zucchini, such as Fusarium wilt, Fusarium wilt and so on. And the growth of zucchini will also become weaker, resulting in a decline in production and reduce their own breeding efficiency. That's all for today's introduction.
