空心厚皮的畸形西瓜是生理性病害,发生较为普遍,轻者降低产量,重的失去食用价值。经试验硼砂能防治空心病。硼元素对作物的作用,促进养分在果实内部的运输。若土壤缺硼养分运输受阻,就停留在皮部成为厚皮,果肉部养分不足形成空心。增施足量硼肥则养分运输畅通,直达果心,成为薄 Hollow pectoral abnormalities watermelon is a physiological disease, occurs more generally, the light to reduce production, heavy loss of edible value. After the test borax can prevent hollow heart disease. The role of boron on crops, to promote nutrient transport within the fruit. If the lack of boron transport of soil nutrients blocked, to stay in the skin become thick skin, lack of nutrients to form a hollow pulp Department. Enriching the application of adequate amount of boron fertilizer nutrient transport unimpeded, direct fruit, become thin
