High-yield and cultivation method of Juhuaxin pomelo

Abstract

The invention provides a high-yield and cultivation method of Juhuaxin pomelo. The method comprises the following steps of (1) selecting an orchard site; (2) digging a hole and improving soil; (3) field planting tree stocks: selecting poncirus trifoliate stock or citrus grandis to graft seedlings; (4) pruning in a natural open centre shape, promoting spring shoots, shearing summer shoots and removing autumn shoots; (5) managing flowers and fruits: spraying gibberellin (CA3) 50mg / kg, 0.3 percent of monopotassium phosphate and 0.1 percent of borax on leaves to prevent fruit drop during a full-blossom period. According to the high-yield and cultivation method of the Juhuaxin pomelo, the poncirus trifoliate stock is adopted to graft the seedlings, so that after field planting, the root system is developed, the stress resistance is strong, the appetency is strong, the adaptability is wide, the tree form is semi-dwarf, the tree potential is strong and healthy, the close planting is suitable for being carried out, early mature and high yield is realized, and the quality is good. The citrus grandis is adopted to graft the seedlings, so that after field planting, the root system is developed, the stress resistance is strong, the adaptability is wide, the appetency is favorable, the tree potential is strong and healthy, the tree form is arborescent, the fruiting is delayed, and the high and stable yield can be achieved during the middle and later periods.

Description

technical field [0001] The invention relates to the field of fruit cultivation, in particular, it provides a high-yield cultivation method for chrysanthemum core pomelo. Background technique [0002] Zhangjiajie chrysanthemum core pomelo (also known as Dayong chrysanthemum core pomelo) is a local variety of red meat sweet pomelo, which has a long history of cultivation. According to "Dayong County Chronicles": "Dayong chrysanthemum core pomelo was cultivated by Huchun in Hujiahe, Xixiping during the Guangxu period of the Qing Dynasty. The pomelo navel has chrysanthemum patterns, so it is named chrysanthemum core pomelo. .By August of the following year, the sour taste will disappear, making it more fragrant and sweet." Before liberation, due to backward technology, there were only 38 adult fruit trees. In the 1960s, more than 100,000 seedlings were propagated by grafting technology, and the pomelo orchard had grown to more than 1,700 mu. The number of trees decreased, and ...

Problems solved by technology

Before liberation, due to backward technology, there were only 38 adult fruit trees. In the 1960s, more than 100,000 seedlings were propagated by grafting technology, and the pomelo orchard had grown to more than 1,700 mu. The number of trees decreased, and after being rescued, they gradually recovered. So far, there are more than 2,000 mu in Famin, mainly distributed along the Lishui River. However, the output has not been high and cannot meet the needs of the market. The supply exceeds demand.
