Yellow skin sprayed sunflower seeds sweet source foliar fertilizer acid and sweetening effect is good

The seedless yellow bark has a large planting area in Yunan, Zhaoqing, Guangdong, but due to the low sugar content and high acidity of the fruit, the lack of flavor has seriously affected the value of the commodity. In order to discuss the effect of sweet sunflower seedlings on the acidification and sweetening of seedless yellow skin, in July 2005, under the guidance and help of Zhang Zhuorong, Zhaoqing Agricultural College, we taught at Zhaoqing Agricultural College in Zhaoqing. Practice bases were demonstrated on the non-nuclear yellow husks. Ten uniform growth cultivars were used for demonstration treatment and control. The treatment areas were sprayed twice on July 6 and July 13 respectively. The surface fertilizer was sprayed at a concentration of 500 times; the same amount of fresh water was sprayed in the control area. On July 31, the experts were fielded and accepted. The average sugar content (measured by a hand-held sugar meter) of the seedless yellow leaf sprayed with the sweet source foliar fertilizer was 13.90%, and that of the spray-treated clear water control was 13.05%. The net increase in sugar content was 0.85%. The relative increase of 7.0%. The average fruit weight was 9.05 g for sprayed sweets, 8.35 g for spray water, and 0.7 g for single fruit weight, an increase of 8.0%. After being tasted and appraised by the experts, spraying sweet sources has good taste, good flavor, and significantly improved its commercial performance. This shows that the sweet sunflower source foliar fertilizer can effectively reduce the acidity of yellow peel fruit and significantly increase the sugar content. Single fruit weight.
