Why do Hami melon seedlings die? A detailed explanation of planting precautions
Hami melon is a very delicious fruit, with a crisp and juicy texture and very high nutritional value, and it is very popular all over the country. Hami melon is mostly grown in the Xinjiang region. During actual planting, what is the reason for dead seedlings? What planting precautions are there?
1. What is the reason for dead seedlings in Hami melon?
1. Excessive fertilizer causes dead seedlings. Although plant growth cannot do without fertilizer, during the seedling stage of Hami melon we should also pay attention to whether our fertilization method is correct. If you want the Hami melon seedlings to grow more robustly, then urea needs to be applied, but if the urea is not diluted and is instead directly buried around the roots of the Hami melon, it will cause root burn, and once the root system is damaged it is prone to the occurrence of some diseases, which also easily leads to dead seedlings in Hami melon. The concentration of the fertilizer we apply must be low, and it is best to apply it by watering after dilution with water.
2. Incorrect watering method. If your watering method is incorrect during the growth period of Hami melon, it can easily lead to the death of a large number of seedlings. When watering at the seedling stage, remember not to water too much. Usually we take water control measures at the seedling stage. If there is a lot of standing water in the field at this time or if the recent rainfall is especially heavy, then it is very easy to cause dead seedlings. At the seedling stage of Hami melon, it is best to keep the soil slightly dry. When the soil becomes dry, we water it thoroughly once, and then there is no need to water for a long period, until the soil becomes dry again before continuing to water.
2. Caused by pests and diseases. During the seedling stage of Hami melon, it is prone to many diseases, so management during the seedling stage is also worth attention. To prevent these diseases, we need to use pesticides in advance for spraying treatment. If some seedlings become diseased, we can pull these seedlings out to prevent them from infecting other seedlings. Before planting Hami melon, the soil needs to be disinfected and sterilized, which can ensure that the diseases are eliminated.
2. Planting precautions for Hami melon
1. Seedling stage management
Seedling stage management of Hami melon is a relatively key matter. If managed improperly during the seedling stage, the later yield will be extremely low. During the seedling stage, the most important thing to pay attention to is the survival rate. After emergence, dead seedlings must be prevented, and if dead seedlings appear, they must be replanted promptly. In addition, if weeds appear and affect the seedlings, they should be understood and removed, so as not to cause weak seedling growth.
2. Water
For Hami melon, its growth and development not only require light and temperature, but also attention to water needs. Proper watering can ensure its normal growth. When Hami melon blooms, at this stage the water demand of Hami melon is very large, so it should be watered reasonably according to climate changes and the dry and wet conditions of the soil, avoiding soil that is too dry or too wet. In addition, by trellising and guiding the vines, the permeability between plants can be increased, allowing the plants to photosynthesize better, accumulate water, and increase yield.
3. Topdressing
During the growth process of Hami melon, a large amount of nutrients is consumed. When the base fertilizer is insufficient, moderate topdressing is needed. When the seedlings grow to 5cm, some urea can be appropriately applied as topdressing, which can promote seedling growth. At this time, it is recommended to dissolve the urea in water, dilute it, and then apply it by watering. This can both avoid root burn and speed up the absorption of the fertilizer. Topdressing at the flowering stage must be carried out before the female flowers open, and can be applied by digging holes between the plants. Fertilization at the fruiting stage is generally carried out after the end of the first harvest.
4. Temperature
The reason Hami melon from Xinjiang in our country is so famous is that the day-night temperature difference there is very large. Therefore, when planting Hami melon, attention must be paid to the issue of temperature difference. The daytime temperature should be higher, while at night it should be lower. This is conducive to the accumulation of sugar in Hami melon, and only then will the sweetness of the Hami melon grown be higher. At each growth stage of Hami melon, the temperature requirements are relatively strict, so attention must be paid during planting.
