Single melon weight 1.5 ~ 3.5 kg, the fruit is long oval, with high sugar content, good flavor, excellent quality characteristics.
It is resistant to storage and transportation, strong commercialization, high economic value.
Through the use of film seedlings, mulching and other early technology cultivation of black beauty watermelon, not only can increase yields of 30% to 50%, but also 20 to 25 days earlier maturity on the _, economic benefits + points significant.
-, sowing seedlings
1, preparation of nutrient soil: the use of nutrient cup seedling, per acre of nutrient soil 150 ~ 180 kg, nutrient soil from 70% of the pond mud, 20% of the rotted organic fertilizer, 10% pure red mud sieve mixing and become.
Each bag weighs about 0.5 kg, and in the middle of the nutrient bag into the 6 to 7 composite fertilizer.
The raw materials for the preparation of nutrient soil can not be used to plant watermelon soil.
2, germination sowing: seeds with 50% carbendazim 500 times solution soaked in 30 minutes of disinfection, and then soaked in water for 4 hours, pick up germination to 70% of the seeds can be sown white.
When sowing, the nutrient soil is first drenched with carbendazim 500 times solution, the seeds are placed flat, about 1 centimeter deep, and the buds are down.
After sowing with nylon film covered with heat preservation nursery, keep the nutrient soil moist, - generally 5 to 7 days after sowing can come out of the soil, after coming out of the soil to human shelling, in order to promote the cotyledons as soon as possible to unfold.
3, cultivate strong seedlings: every 7 to 10 days with 50% Rogaine 800 times liquid and 50% carbendazim 500 times liquid spray wine seedlings 1 time.
Bed - when the first true leaves grow out, began to use rotted human urine to water 10 times watering, watering every 1 day - times.
The film can be lifted early in the morning on a sunny day for seedling refining, and re-covered in the evening.
The seedlings can be fixed when they grow to 2-3 true leaves.
ニ、整地定植
1、选地和整地：选取充分阳光、排灌方便、土层深厚疏松的砂质地块筑畦种植，畦宽3米，沟宽0.5米，畦面稍带弧形。
When preparing the ground, you can evenly spread 50 kg of quicklime per acre, both disinfection andㄡ can neutralize soil acidity.
Per mu of rotting pig and cow dung 1000 ~ 1500 kg, 20 ~ 25 kg of calcium superphosphate, 30 kg of compound fertilizer, potassium sulfate 10 kg as fertilizer, into the planting hole and soil mix.
2, planting: seedlings grow to 2 ~ 3 true leaves when transplanted, spacing 0.5 meters, mu planting 300 ~ 330 plants.
After transplanting, use 50% carbendazim 500 times solution as root fixing water.
Then in the seedlings on both sides of the bed each paved - a strip of film, and make the film close to the bed, compacted without lifting over.
