Water and fertilizer management of protected melon

Apply enough base fertilizer, fine soil preparation, and smooth the noodles, so that the plants can be evenly planted after the irrigation, and the soil moisture will be maintained in the seedling stage and the vine growing period to maintain the high soil moisture and certain air temperature to promote the cicada and make the stem thick. The leaf area is large, ensuring a strong vegetative growth potential, and laying a foundation for high yield in the future (the fifth true leaf of the cotyledon is flat for the seedling stage, and the fifth true leaf appears the first solid flower for the opening period).

Timely pouring the fertilizer into the fertilizer. After setting the melon, it is the critical period of water and fertilizer for melon growth. Very early fertilization and watering can promote the expansion of melon, which can increase the income. If the puffed water is poured too late, the critical period of fertilizer and water has passed, and it cannot be remedied. Can not play a role, resulting in reduced production.

During the whole growth process of melon, the water should be kept even. Generally, the water content of the seedlings is more than that of the seedlings, and the air humidity is relatively large. As a result, the water is more in the early stage, and the water is less in the later stage, and the air temperature is smaller. The fruit logistics department is generally no longer watered for 25 days. It has entered the ripening stage of melon and controls the water to maintain its high sweetness.

3-5 days after pouring the seedling water, it is necessary to cultivate the loose soil in time, cover the film and keep it warm for a continuous sunny day, and press the second water to promote the sputum in time. The test shows that once the water is insufficient in the early stage, the air is dry and the water is dry, causing water shortage. The stem is thin and weak, the leaf area is small, the vine is elongated slowly, short, the melon is small, the melon is not normal, and the operation is laborious.

After the fruit set, KH2PO4×500 times solution and 0.3% white sugar should be sprayed every week to increase the sweetness and good quality.
