When do melons usually grow? What are the matters needing attention in fertilization?

Melon is a kind of fruit melon planted widely in all parts of China. Different varieties have different tastes, shapes and colors. Generally, it matures in midsummer. Melon whole plant also has certain medicinal value, can induce vomiting, dehumidification, jaundice and other effects. When do melons usually grow? What are the benefits of fertilization?

When do melons usually grow?

1. Melon is generally propagated by seeds when planted. There are many varieties. It is suitable for sowing in August to October, no later than November. Spring sowing can generally be in February to March.

2. In order to ensure good harvest during Qingming Festival and Grain Rain Festival, for example, American zucchini with a long growth period can be considered for early sowing, and those with a short growth period can be postponed for one sowing, such as early green zucchini.

2. What are the precautions for melon fertilization?

1, can no longer use urea after watering

The nitrogen contained in urea is divided into amide, and amide nitrogen can be converted into ammonium carbonate by urease function secreted by soil microorganisms before it can be absorbed by vegetables or adsorbed and preserved by soil. Watering with urea, for example, will cause losses, so whether urea is used as a base fertilizer or as a topdressing, it is necessary to fully transform it within 5 to 7 days after application before watering to avoid losses.

2, can not be applied multiple times ammonium sulfate

In the acidic soil or calcareous melon field, if ammonium sulfate is continuously applied for many times, the acidic soil will become more acidic, and the calcareous soil will be hardened, which will seriously affect the normal growth of melon.

3, can not be a large amount of calcium

If phosphorus fertilizer is applied to melon field for several years continuously, too much phosphorus fertilizer will be supplied, which will be extremely unfavorable to the normal growth and development of melon, resulting in early decline and wither of melon, greatly reducing crop yield and quality.

4. Ammonium bicarbonate cannot be applied when the melon is short of water.

Ammonium bicarbonate is very unstable, relatively easy to volatilize loss, especially in the melon drought when the performance of less water is more obvious, resulting in greater losses. Therefore, if ammonium bicarbonate is applied to melon fields, whether as base fertilizer or topdressing, it is necessary to apply it deeply under wet melon fields, and it is necessary to turn over the soil immediately after application. In case of dry weather, water can be added or watered after application.

5, can not spray too high concentration of nitrogen fertilizer

If the application of urea ammonium sulfate and other solutions sprayed on melon, although it can make melon fat, beautiful color, significantly increase the yield, but nitrate may also accumulate in a large amount on the melon skin, after we eat it will pose a great threat to human health.
