First, cultivation management program: improve the growth environment conditions.
1. Ditch drainage and flood control: In June, there is more rainfall. The melon land should be drained and flood-proof. It can deepen the ditch and add water pump drainage to prevent the roots of the watermelon from immersing in water and causing the roots to die.
2. Strengthen ventilation and light transmission: In June, the watermelons that have been planted densely can be properly removed. If the growth is too strong, the pruning can be properly pruned, and the number of melons can be properly controlled to reduce nutrient loss and increase the light receiving area. To ensure the safety of watermelons in summer, improve production and quality.
3, before the flowering, young fruit period, fruit expansion period, spray the strong fruit Tieling solution, may make the cucurbit thickening, strengthen the nutrient directional transport, promote the rapid development of the melon, the melon is beautiful, the juice is delicious The growth cycle is not falling, not falling, no cracked melon, no deformed melon.
Second, the nutrient supply program: the application of new high-fat film 800 times liquid during fertilization and topdressing can improve the absorption and utilization of fertilizer, save costs, and meet the needs of childbirth in time.
1. Fertilization program in high temperature period: The watermelon grows fast in the high temperature season, and the nutrients to be supplied are comprehensive and easy to absorb quickly. It is difficult to meet the demand of watermelon for rapid absorption of whole nutrients in simple use of compound fertilizer. Therefore, watermelon can be used as follows in the high temperature season: fertilization: use Cuikang Chong fertilization 500~750 with good water solubility, fast absorption of watermelon and 10 kinds of nutrients Ke + Cui Kang promotes root fluid 400 g / mu as top dressing with water, once every 10 days, and meet the needs of watermelon growth in high temperature season. At the same time, in order to adjust the soil structure, prevent soil compaction, improve fertilizer utilization, and delay root aging, each batch of melon can be applied once more to the seaweed fertilizer (5 kg / mu), which is conducive to maintaining the growth of watermelon to prevent premature aging.
2, potassium and magnesium to prevent premature aging: high temperature season in summer, watermelon is prone to old leaves yellow, leaves coke dry potassium and magnesium symptoms, leaf life is short and premature aging, seriously affecting later yield. The leaf surface can be quickly supplemented with potassium and can be washed with 700 times foliar spray of Cui Kang, once every 7 to 10 days; or when the soil is fertilized, 10 kg/mu of drip irrigation with potassium and magnesium sulfate is added, and the effect of applying seaweed fertilizer is better.
3, supplement the trace elements: during the period of melon, use Cui Kang Jinpeng liquid 1500 times solution spray 1 or 2 times, effectively prevent deformed melons, hollow melons, etc.; expansion period (egg size) with Cui Kang Shengli liquid 600 times + Cui Kang Bao Li ( Or Cui Kang Jin Potassium) sprayed 1 or 2 times 700 times, effectively prevent watermelon white or yellow heart, and reduce thick skin melon, improve the quality of watermelon, can also delay premature aging.
4, restore the growth: the decline of the vines in the serious melon garden; with Cuikang high nitrogen flushing fertilization 500 grams + Cui Kang root solution 300 g / mu drip irrigation 2 to 3 times (including the application of a seaweed fertilizer 10 kg / mu ), can quickly restore growth and delay root aging.
