Characteristics: It is a mid-late maturing triploid seedless watermelon variety with a total growth period of 105 days and a fruit development period of 32-35 days. The first female flower node Section 7, female flower spacing 7 sections; plant growth robust, strong branching, easy to set fruit; fruit ball type, pure black skin, covered with thick wax powder, beautiful appearance, fruit peel thickness 1.2cm, hardness , Storage and transportation, single fruit weight 6-8kg, red flesh, crispy meat, sweet; seed brown, 1000-grain weight 55g.
Identification of resistance: In 2007, the biotechnology center of Zhengzhou Fruit Research Institute of the Chinese Academy of Agricultural Sciences identified the artificial rubbing inoculation at the seedling stage: susceptibility to virus disease (grade 3.85); identification of the soil in the greenhouse seedling stage: sensation of wilt disease (plant strain rate 100 %).
Quality Analysis: In 2008, the Ministry of Agriculture Quality Supervision, Inspection and Test Center (Zhengzhou) detected: Center sugar 11.76%, edge sugar 8.96%. .
Yield performance: In 2006, the provincial seedless group regional test, the average yield per mu was 2259.8kg, an increase of 6.4% over the control Heimei No. 5; in 2007, the trial yielded an average of 2305.8kg per mu, an increase of 5.8% over the control Heimei No. 5. In 2008, the province's non-seed production test, with an average yield of 2575.6 kg per mu, was 9.3% higher than the control black honey No. 5.
Appropriate areas: planted throughout the province.
Cultivation Techniques:
1. Seed treatment: soaking in warm water at 55°C for 15 minutes (with rapid stirring to bring the water temperature down to 20°C) to soak for 8-12 hours, washing and draining, and breaking the shell. Wrap with a warm cloth at a constant temperature of 33°C. 24h germination, bud length
About 0.5cm can be sown.
2. Sowing period: Protected cultivation in late January or early February seedlings, mulching cultivation in the middle of March seedlings or early March end of April broadcast.
3. Density: Protected land is about 500 trees per acre, mulching 600 trees per acre, double vines or triple vine pruning. Reasonably configure diploid watermelons as pollination varieties, flowering period, artificial pollination every morning,
Help fruit set. The third female flower left fruit, 1 fruit per plant.
4, field management: re-basal fertilizer, light to mention the Miao Fei, Qiao Shi fruit fertilizer, watering foot swelling melon water. Comprehensive prevention and control of pests and diseases. Harvest timely.
Systemic arterial blood pressure (BP).Blood pressure is the pressure on the wall of the blood vessel when the blood is flowing in the blood vessel.Systolic bloo d pressu re (SBP) is the highest pressure on the arteries when the ventricles contract and the blood flows from the ventricles into the arteries.When the ventricles relax, the arteries flex back and the blood slowly continues to flow forward, but the blood pressure drops. This pressure is called DBP (dia sto lic blood pressure).
