First, the cultivation management program: to improve the growing environment conditions. 1, ditching drainage flood control: June more rainfall, melon to do a good job of flood prevention, can open the ditch, add water pump drainage, prevent watermelon roots from flooding and cause root death. 2, to enhance ventilation and light transmission: In June, the planted dense watermelon can be properly unplugged part of the growing excessively prone to appropriate pruning, reasonable control of the number of seated melons, to reduce nutrient depletion, increase the light receiving area, and rattan leaves , To ensure that the watermelon is safe in summer, and to increase the output and quality. 3. Spraying Zhuanggutiling solution before flowering, young fruit stage, and fruit expanding stage may make Guatea thicker, strengthen nutrient-oriented delivery volume, promote rapid development of melon body, melon type is beautiful, and juice is more delicious The growth cycle does not fall, no melon, no crack melon, no abnormal melon. Second, the nutrient supply program: Fertilizer and topdressing when adding 800 times the new high-fat film can increase the absorption and utilization of fertilizers, cost savings, to meet the needs of fertility. 1. High-temperature fertilization program: High-temperature season watermelon has fast growth, and the nutrients provided by it are comprehensive and easy to absorb quickly. Simple use of compound fertilizer is difficult to meet the needs of watermelon for rapid absorption of nutrients in time, so the watermelon in the hot season can be as follows: fertilization: with water-soluble, fast absorption of watermelon and contains 10 kinds of nutrients Cui Kang Chongfei 500 ~ 750 Ke + Tsui Kang root liquid 400 grams / acre as top dressing with water irrigation, a time interval of about 10 days, and when to meet the needs of high temperature watermelon breeding needs. At the same time, in order to regulate soil structure, prevent soil compaction, increase fertilizer utilization, and delay root ageing, each batch of melons can be increased by one time Saide seaweed fertilizer (5 kg/mu), which will help maintain the growth of watermelon and prevent premature aging. 2, potassium and magnesium to prevent premature aging: Midsummer heat season, watermelon prone to old leaves yellow, leaf scorch deficiency potassium and magnesium symptoms, short-term premature leaf blade decay, seriously affecting the late production. Foliar quick potassium and magnesium supplements can be used Cui Kang Bao Li 700 times foliar spray, 7 to 10 days once; or soil fertilization when applied potassium sulfate magnesium 10 kg / acre drip irrigation, combined with the application of Saide seaweed fertilizer is better. 3, supplement the trace elements: seat melon during the use of Cui Kang Jinpeng 1500 times liquid spray 1 to 2 times, effectively prevent deformed melon, hollow melon, etc.; expansion period (egg size) with Tsui Kang Shengli liquid 600 times + Chong Kang Baoli ( Or Tsui Kang Jin Potassium) 700 times sprayed 1 to 2 times, effectively prevent watermelon white or yellow heart, and reduce the thick skin melon, improve the quality of watermelon, but also delay premature aging. 4. Restoring the growth: The melon garden is seriously degraded by Fujimori; use Cui Kang's high-nitrogen fertilization 500 g + Tsui Kang root-enhancing solution 300 g/mu drip irrigation 2 to 3 times (adding a Saide seaweed fertilizer 10 kg/mu ), can quickly restore growth and delay root aging.
