摘要
研究了脆皮金柑在当阳市的抽梢和开花结果物候期、春梢结果母枝所开花的坐果率和春梢结果母枝长度、粗度以及结果枝类型的分布。结果表明,脆皮金柑春梢萌芽期在3月上旬,停梢期在4月上旬;夏梢萌芽期在6月下旬,停梢期在7月下旬;秋梢萌芽期在8月中旬,停梢期在8月下旬。第1批花开在6月中旬,主要开在春梢上,花量大;第2批花开在7月下旬,主要开在夏梢上,花量较少;第3批花开在8月中下旬,花量很少,且开在夏梢上。第1批花的坐果率为9.87%。粗度在0.21~0.35 cm之间、长度在6.1~12.0 cm之间的春梢结果母枝数量最多,分别占结果母枝总数的76.2%和50.9%。春梢结果母枝长度在18.0 cm范围内,随着母枝长度增加单位母枝上的有叶结果枝数量增多;结果母枝长度为6.1~12.0 cm,单位母枝上无叶结果枝数最多。结果母枝粗度在0.5 cm范围内,随着母枝粗度增加,单位母枝上有叶结果枝数和无叶结果枝数增多。
Germinating,flowering and fruiting phenological phase,fruit set rate on spring shoots,the distribution of the length and thickness of the mother shoots sprouting in spring and the types of the fruit shoots on them of Fortunella crassifolia Swingle cv. Changanjingan plants in Dangyang City were studied.The results showed that the spring shoot germination period was in the early March, and their stop growing period in early April;the summer shoot germination period was in late June, and their stop growing period in late July ; the autumn shoot germination period was in the middle of August, and their stop growing period in late August. The first batch of flowers blossomed in the middle of June, and were mainly borne on the spring shoots and had a large amount;the second batch blossomed in late July ,and were mainly borne on the summer shoots and had less amount ;the third batch blossomed in the mid-late of August, and were mainly borne on the summer shoots and the amount was little. The first batch of flowers had a fruit set rate of 9.87%. The fruiting mother shoots sprouting in spring with 0.21 to 0.35 cm in thickness and 6.1 to 12.0 cm in length were in the largest number, accounted for 76.2% and 50.9% of the total number of fruiting mother shoots, respectively. Within 18.0 cm range in length of them,the number of leaf fruit shoots on them increased with the increase of their length;the leafless fruit shoots were in the largest number in their length from 6.1 to 12.0 cm. Within 0.50 cm range in thickness of them ,both of the number of leaf fruit shoots and leafless fruit shoots on them increased with the increase of their thickness.
