摘要
对‘红香蕉’和‘小国光’等品种进行叶面喷施钛化合物表明,钛对苹果树新梢生长、干物质积累及光合作用等具有较明显的促进作用。其中‘红香蕉’喷钛后,果实着红面积≥1/2的数量比对照增多47.0-48.2％,青果数下降54.8-56.5％,果实中游离态Vc含量增高31.2-40.7％,可溶糖增加8.5-14.2％,≥2级果增加2.5-5.4％,等外果减少64.3-88.9％。现已试用500余亩,‘红香蕉’每亩可获纯收益134.97元,‘小国光’为64.42元,产投比分别为12.5:1和10.5:1。
The effects of foliar application of Ti compound on apple trees growth and quality of fruits were studied at TengZhou city of Shan-dong province, The results of field experiments are as follows.
1. The foliar application of 2 and l0ppm Ti compound enhanced the growth of new shoots, accumulation of dry matter and photosyn-thesis. They increased by 2.4-5.4%(new shoots), 8.40-25.6,% ( weight of 100 leaves ) and 24.5-61.2% ( photosynthesis ) respectively in comparison with control.
2. After foliar application of 2 and lOppm Ti compound the number of red Delicious fruits which surface coloring area reached or over 1/2 increased by 47.0-48.2%, the number of green apple fruits decreased 54.8-56.5% and the contents of free Yc and soluble sugar were increased by 31.2-40.7% and 8.5-14.2% over control respecti-vely.The number of fruits in first and second class increased 2.5-5.4% and bad fruits decreased 64.3-88.9% in comparison with control.
