Management techniques of zucchini at seedling stage

Zucchini is a common melon vegetable, which has a very high nutritional value and is rich in nutrients, so it is welcomed by many people, and its market demand is also very large. When we plant zucchini, we should pay attention to the management of zucchini seedling stage in order to ensure the normal growth of zucchini. So how to manage zucchini at seedling stage? The following editor brings you the management technology of zucchini seedling stage, let's have a look!

1. Temperature management

After the zucchini seeds are sown, we should pay attention to create a suitable temperature environment for the zucchini. The temperature should be kept at about 30 degrees during the day and 20 degrees at night. When about half of the seeds emerge, the film should be uncovered in time. And reduce the daytime temperature to about 25 degrees. Then, when about 80% of the seedlings are unearthed, the temperature will drop by about 5 degrees during the day and remain at 15 degrees at night. Ensure that the zucchini seedlings emerge neatly and the Hypocotyl is strong.

2. Water and fertilizer management

Because the seeds of zucchini are relatively large, its ability to arch soil is also relatively strong. Therefore, if the soil cover is thin after sowing or too much watering before emergence, it is very easy to lead to soil consolidation. At the beginning of emergence, the seed coat of the seed is more difficult to fall off, so it is easy to be unearthed with a cap, and there is also the danger of bud drying. So we should not only do a good job of seed soaking and sprouting before sowing, but also pay attention to watering the seedling bed water. Then it is best not to water the seeds before emergence, and the thickness of the covered soil should be kept at about two centimeters. If the phenomenon of wearing a cap occurs, then it is necessary to properly spray warm water or sprinkle some moist rare earths to promote the cap off.

3. Separate seedlings and refine seedlings

When the cotyledons of the seedlings are flattened and the true leaves are gradually exposed, they should be moved to the nutrition bowl at the right time. It can also divide seedlings directly on the seedling bed to provide sufficient growth space for all seedlings and improve the rate of strong seedlings. Then we have to do a good job in seedling refinement. If the seedlings are raised in low temperatures such as winter and spring, the temperature should be kept at about 20 degrees during the day and 7 degrees at night when planting for a week. If you raise seedlings in summer and autumn, then you should gradually remove the sunshade net and control the moisture. After seedling refining, the environment of the seedlings should be consistent with that of the planting field as far as possible to ensure that the seedlings can slow down as soon as possible.

4. Other management

In the late stage of seedling growth, if the external temperature suddenly changes, then we should pay attention to timely adjustment. Be careful to remove the mulch in time after the rainy season, usually when covering the mulch, just keep a distance of 50cm or so from the ground. After the emergence of seedlings, we should pay attention to the timely establishment of seedlings, if there is the phenomenon of dead seedlings, then we should do a good job of replenishing seedlings. At the same time, we should also pay attention to artificial weeding to avoid affecting the growth of seedlings, and finally do a good job in the prevention of diseases and insect pests.

The above is a brief introduction of zucchini seedling management technology. That's all for today's introduction. This article is for reference only. I hope it can be helpful to everyone.
