Improved cultivation method of three-red crystal grapefruit

Abstract

The invention provides an improved cultivation method of three-red crystal grapefruit. In the improved cultivation method, common grapefruit is top-grafted on Wenzhou grapefruit. The improved cultivation method has the key cultivation points: the three-red crystal grapefruit is fond of shading and is suitable for growing at flat and gently innumerable mountains with low altitude at southeast in China; the sapling needs enough fertilizer for promoting tips to grow; water management needs to be enhanced in order to reduce split fruit; 90% of the fertilizing amount for the whole year can be arranged at the time after picking the fruits to early summer, especially, potash fertilizers are intensively applied in summer; an open window is arranged at a selectively-cut upright great branch; a side window is arranged at the periphery of the upper part, a small window is arranged at the fruiting branch at the lower part; intensive branches, upright branches and exuberant branches are wiped out; sapling grows very exuberant and needs to perform reasonable girdling to promote fruits to put into early production; the first girdling is performed during the first ten-day of November- the first ten-day of December and the second girdling is performed after the flowers are fell for 2 / 3h; the girdling position is a base part of blooming main branch; the fruits are bagged; and the fruits are kept fresh and packaged by applying a POF (Plastic Optical Fiber) heat shrinkable film far infrared fresh-keeping packaging technology.
