Embodiment 1

[0025] In October 2005, the red-fleshed loquat 'Zaozhong 6' was used as the female parent, and the same amount of mixed pollen of the two loquat varieties 'Zaozhong 6' and 'Donghuzao' was used for pollination and hybridization, and the hybrid was obtained in April 2006 There are 13 F1 seeds in the progeny; the red meat loquat 'Donghuzao' is used as the female parent, and the pollen of the two loquat varieties of 'Zaozhong 6' and 'Donghuzao' is pollinated and crossed. The hybrid offspring was obtained in April 2006 F1 seeds 10 grains. 23 hybrid progenies were sown and planted on the spot with a plant-to-plant spacing of 2 meters and a row spacing of 3 meters, and then cultivated and managed according to the technology of the present invention. As a result, more than 50% of the seedlings flowered and bear fruit after 42 months of childhood, and the 54 months of 'Zaozhong 6' as the female parent all ended the childhood and began to bloom and bear fruit. The 'Donghu Zao' loquat as...

Embodiment 2

[0029] In October 2007, the red-fleshed loquat 'Zaozhong 6' was used as the female parent, and the same amount of mixed pollen of the two loquat varieties 'Zaozhong 6' and 'Donghuzao' was used for pollination and hybridization, and the hybrid was obtained in April 2008 There are 27 F1 seeds of offspring; the red-flesh loquat 'Donghuzao' is used as the female parent, and the pollen of the two loquat varieties of 'Zaozhong 6' and 'Donghuzao' is pollinated and crossed. The hybrid offspring was obtained in April 2008 37 F1 seeds. A total of 64 of the hybrid offspring were raised with nutrition bags, and were planted in February 2009 with a plant spacing of 3 meters and a row spacing of 3 meters, after which they were cultivated and managed according to the technology of the present invention. As a result, more than 50% of the seedlings flowered and bear fruit after 42 months of childhood, and the 54 months of 'Zaozhong 6' as the female parent all ended the childhood and began to b...

Embodiment 3

[0035] On May 4, 2008, 10 shoots of 'Zaozhong No. 6' were used as breeding materials. After the 10 shoots were cut short, they were soaked in colchicine (the branches were wrapped in sanitary napkins and dripped with liquid medicine), and bagged The shading is listed and marked, and the same branches are treated again after 24 hours, and they are bagged for shading. After May 6, the bags are removed to remove the paper. About 30 days later, it was cut short and soaked, and a new shoot grew on the branch tip. From November 2008 to April 2009, the branch tip blossomed and bear fruit, with 4 fruits and 24 seeds in total. Seedlings were raised with nutrition bags, and 13 seeds Germinate and grow. In April 2010, 13 seedlings were obtained, and transplanted according to the distance between plants and rows of 3 meters and 4 meters. Due to the damage of typhoon, 11 plants finally survived in December 2012. See Table 3 for flowering and fruiting results.

Abstract

The invention discloses a cultivation method capable of shortening the juvenile phase of loquats. The cultivation method comprises the following steps: performing seed direct sowing seedling culture or nutritional bag seedling culture, cultivating loquat double-layer trunk tree forms, applying fertilizer, applying a composite plant growth regulator and the like. The double-layer trunk tree form is cultivated by utilizing the characteristics that the loquat has high dryness, remarkable layer property, high germinating ability and high branching ability; furthermore, the composite plant growth regulator is sprayed on new shoots, and seedlings are promoted to develop towards the reproduction and growth direction. The cultivation method has relatively good and stable effect, the juvenile phase of the loquats is kept for 2.5 to 6 years, mainly for 3.5 to 4.5 years, the juvenile phase of the loquats is shortened by 2 to 3 years, and the problem that the juvenile phase of the loquats is long is effectively solved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a cultivation method for shortening the childhood period of loquat. Background technique [0002] Childhood is the period that a seed goes through from germination to flowering potential. The length of childhood is generally measured as the interval from seed germination to first flowering and fruiting. The childhood period of loquat is relatively long, as long as 4-8 years, generally 5-7 years, resulting in long loquat breeding cycle, high breeding cost, and slow variety improvement, which is quite unfavorable to the loquat industry. It is a problem that has long plagued loquat production and loquat breeding. important question. Therefore, it is an important topic in loquat production and loquat breeding to study shortening childhood and promoting early fruiting of loquat. For decades, many agricultural departments and scientific research institutions at home and abroad...
