Skillful fertilization, watermelon production and sweetening three methods one, application of biological sweetening spirit biological sweetening spirit is based on false, calcium, boron, copper, zinc, manganese, cobalt, with nitrogen, phosphorus, magnesium and other nutrients with the development of production A bio-water sweetening colorant for watermelons. After applying the biotite sweetening spirit, the fruit setting rate can be increased by more than 10%, the yield can be increased by more than 15%, and the sweetness can be increased by 0.8-1.5 degrees. Application method: It can be used in the flowering period, young fruit period, fruit enlargement period and mature period of crops. 1, diluted 500-800 times the liquid for foliar spray. 2, diluted 500-1000 times liquid irrigation root. 3, diluted 10-20 times liquid dry. In addition, this product can be used in conjunction with a variety of pesticides and can increase the adhesion of pesticides and improve efficacy.
Second, the appropriate application of microbial microbial fertilizer: use 1-2 kilograms per kilogram of golden treasure microbial fungus, can effectively prevent the death of seedlings, improve the application of trace element fertilizers and organic fertilizers, chemical fertilizer effect, promote and enhance photosynthesis Efficiency, promote sugar synthesis, improve watermelon sweetness.
Third, the application of boron fertilizer boron fertilizer is one of the indispensable trace elements of watermelon growth and development. The lack of boron in watermelon plants will reduce the yield, reduce the sugar content, and it will appear as budding or flowering. When the boron deficiency is severe, the female flower will also be detached from the spermatozoa, resulting in severe reduction of production. According to the test, the application of boron fertilizer in watermelon, melon vine without the application of boron fertilizer 0.24 meters longer, flowering 3 days in advance, the rate increased by 7.4%, 11.7% increase in yield, sweetening 0.7 degrees. Boron fertilizer can be used as a basal fertilizer on watermelons and top dressings outside roots. 1 Keshi. 0.5 kg to 1 kg of borax per acre, or 3.5 kg to 7 kg of boron magnesium fertilizer, or 15 kg to 20 kg of boron sludge, mixed with appropriate amounts of nitrogen and phosphorus fertilizer, and turned into soil when soil preparation. Generally do not use furrows or acupuncture, so as to avoid local soil boron concentration is too high and have a toxic effect on watermelon.
2 top dressing. Foliar spraying with 0.1% to 0.2% borax solution.
