Lifting the sowing and planting quality Before the watermelon is sown or planted, the soil is fully drenched, and the hoe is combined to make the sorghum flour. Planting or planting watermelon seedlings should be conducted in the morning in sunny weather. Bottom water must be poured and there should be 2 to 3 sunny days after sowing or planting. When planting watermelon seedlings, try not to touch the cover soil or break the nutritious soil blocks and nutrition paper bags to avoid injuring the watermelon seedlings. Cover with fine soil after sowing or planting.

When cultivating root soil watermelon seedlings are excavated in time or after field planting in Daejeon, cultivating loose soil regularly. Watermelon seedlings will be cultivated 6 to 7 times. The first cultivator has a depth of 5-6 cm, followed by cultivating once every 4 to 5 days. With the growth of watermelon seedlings and the expansion of the root system, the depth of cultivator should be shallow, with a depth of 3 to 4 cm. Transplanting colonized watermelon seedlings, the number of cultivating to 3 to 5 times is appropriate. The first cultivator is carried out after easing the seedlings, and then cultivating once every 5 to 7 days. The depth is 5-6 cm, preferably after watering and raining.

Appropriately increasing the amount of fertilizer and water In the morning when the temperature is relatively high, the amount of watering should be appropriately increased. When basal fertilizer is insufficient, urea can be topdressed before watering to promote its growth. Specific practices: In the 20 cm from the roots of watermelon seedlings, open a shallow groove of 3 to 4 cm deep, each plant applied 20 to 30 grams of urea, watering after covering the soil.

Glutamic acid, is an acidic amino acid. Molecules containing two carboxyl groups, chemical name for α-amino-pentanedioic acid. Glutamic acid was discovered by lisuoxun in 1856, is a colorless Crystal, fresh, slightly soluble in water, soluble in hydrochloric acid, isoelectric point 3.22. Abound in cereal protein, animal content in the brain and more. Glutamic acid in vivo protein metabolism plays an important role in the process, participating in many important chemical reactions in animals, plants and micro-organisms. Msg containing small amounts of glutamic acid.
