1. Water management: In order to reduce the growth of pathogens and improve the quality of melons, the humidity in the shed should be controlled throughout the growing season, and the sheds should be kept dry. Generally, it is not necessary to resist drought to meet the water demand of melons. Only in the fruit expansion period, depending on the soil conditions and appropriate topdressing with some fertilizer, timely spraying new high-fat film, not afraid of the sun evaporation, can adjust the water absorption, drought and rain.
2, fertilizer management: the land that has been applied to the base fertilizer, the general can not be topdressed before the melon, when the size of the young melon eggs, began to apply the fertilizer. Expanded melon fertilizer should be based on quick-acting nitrogen fertilizer, and appropriate application of quick-acting phosphorus and potassium fertilizer. The amount of application depends on the growth of the melon seedlings. Application method: It is advisable to apply the fertilizer after the water is applied to the roots. In order to prevent the burning of the root system, it is required to apply a cave at 30-40 cm from the root of the watermelon. It can also be sprayed with foliar fertilizer roots, once a week, can be sprayed 2-3 times, which is beneficial to promote plant robustness, enhance resistance, and also help to increase the sugar content of the fruit and improve the quality of watermelon.
3, the application of fertilizer: it should be carried out in the morning on a sunny day, so the temperature is low, the root activity will not be blocked due to the sharp drop in ground temperature caused by watering, resulting in leaf wilting, and even plant death. 2-3 days after topdressing and topdressing, the greenhouse film should be exposed to a larger extent, and the ventilation should be increased to prevent the ammonia from being burned during the conversion process. Stop the supply of fertilizer and water about 10 days before the ripening of the melons. Otherwise, it is easy to cause "anti-birth" or "stubborn rot" inside the melons and fruits. Spraying the strong melons in time can make the cucurbits thicker and strengthen the directional delivery of nutrients. The melon body develops rapidly, the melon shape is beautiful, the juice is delicious and delicious; the growth cycle does not fall, no melon, no cracked melon, no deformed melon.
