长期以来,我省柑桔以中熟品种尾张当家,总面积达24万公顷,产品集中上市,交通运输和市场压力大,果形偏小,品质偏差,结果大小年现象明显,经济效益不高。因此,必须通过高接换种迅速进行品种更新,优化柑桔品种内部结构,增大特早熟、迟熟良种比例,降低中熟品种比例,使特早熟、中熟、迟熟品种比例逐步趋于合理。现介绍柑桔高接换种技术要点如
For a long time, the citrus in our province takes the tail of the middle-aged varieties with a total area of 240,000 hectares. The products are concentrated on the market, the transportation and the market are under pressure, the fruit shape is small and the quality is poor. The result shows that the annual size is obvious and the economic benefit is not high. Therefore, it is necessary to speed up the breed renewal, optimize the internal structure of citrus varieties, increase the proportion of special precocious and late mature varieties, reduce the proportion of medium mature varieties and make the proportion of special precocious, medium ripe and late mature varieties gradually reasonable. Are introduced citrus high exchange technology points such as
