Three-step cultivation method for improving the seedling emergence rate and early fruit bearing of cherry hybrids

Abstract

The invention discloses a three-step cultivation method for improving the seedling emergence rate and early fruit bearing of cherry hybrids. The method comprises following steps:1) hybrid seed collecting; 2) hybrid seed disinfecting and storing; 3) accelerating germination of hybrid seed; 4) sowing and seeding raising for hybrid seeds; 5) transplanting for hybrid seeds; 6) field hybrid seedling root-irrigation, spraying foliar fertilizer and growth regulator; 7) hybrid seed field planting and cutting, controlling vertical growth and promoting new branches; 8) pinching and promoting flower buddifferentiation. The invention accelerates the growth of plants by artificially breaking dormancy, seedlings of the hybrid seeds in the same year and spraying plant growth regulators and insecticides,fungicides and foliar fertilizers; planting hybrid seedlings and cutting, controlling erect growth, and promoting new shoots; pinching, promoting flower bud differentiation, achieving advancing of the first flowering time of hybrid seedlings, and shortening the cross-breeding cycle of Chinese cherry.

Description

Technical field [0001] The invention belongs to the technical field of fruit tree breeding, and specifically relates to a three-step breeding method for improving the seedling rate and early fruiting of cherry hybrids. Background technique [0002] With the progress of society and the development of science and technology, in order to meet people's needs, fruit tree varieties are constantly updated and replaced. The cultivation of new fruit tree varieties is an eternal research topic. my country's fruit tree resources are rich, widely distributed, and have a long history of cultivation. With the development of science and technology, fruit tree breeding has also made certain progress. Conventional breeding methods for fruit trees can be divided into two categories: the first is to improve species through genetic mutations, such as bud mutation breeding; the second is gene exchange and recombination, mainly including seed breeding and artificial hybridization. At present, the mos...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: (1) the seeds collected in the current year are stored in sand and stored until the next year sowing, resulting in an increase in breeding time; (2) the method of burying sand in sand is generally used for low-temperature sand storage, and the seeds are prone to mildew, which has certain effects on hybrid seeds. (3) Sowing in large fields, the emergence rate is not high, and the uniformity is poor

(4) There are many bacteria in the field soil, and the uneven nutrients lead to slow growth of hybrid seedlings; (5) The cycle of flowering and fruiting is longer
