Problems solved by technology

There are many kinds of chicory, among which the bud bulbs of softened chicory are the top grade among vegetables. They are widely planted and sold in Europe, the United States, Japan and other countries and regions, but there are only small-scale introductions in my country at present.
[0003] Because most of the chicory seeds sold abroad are hybrids of the first generation, it is difficult to save seeds, and there are problems such as high prices, complex varieties, and large differences in traits, which are not conducive to direct large-scale introduction and cultivation. Therefore, it is necessary to independently cultivate fine varieties, and quickly Propagation of seeds is an important link in the cultivation of fine varieties

Embodiment 1

[0020] The impact of embodiment 1 different harvest periods on seed yield and quality

[0021] On September 22, 2017, select chicory plants with excellent properties and strong growth, and pick the vegetative buds (not less than three growing leaves) that germinated at the root neck for cuttings. The cutting substrate formula is: vermiculite 5L , coconut bran 10L, dried decomposed manure 0.5kg, bone meal 0.1kg. Observed on October 23, the cutting buds had all taken root, and 12 plants were transplanted to the field. All transplanted seedlings survived within 10 days, grew well and overwintered safely. Bolting began at the end of March, flowering began on May 17-21, full flowering began on May 22-24, and the amount of flowering decreased significantly after June 19. Harvest on June 27, July 7, July 16, and August 9, 2018, 3 plants each time, and store the harvested plants (the branches with inflorescences on the ground) in a shelter from rain, In a cool and ventilated place, ...

Embodiment 2

[0026] Example 2 The influence of picking vegetative bud cuttings at different times on the yield of chicory seeds

[0027] On September 22 and October 24, 2017, chicory plants with excellent properties and strong growth were selected, and the vegetative buds germinated at the root neck were picked for cuttings. Three plants were transplanted to the field on June 23, and all were harvested on June 27, 2018. During this period, all plants were inspected, and their morphological indicators, growth process and seed yield are shown in Table 2.

Abstract

The invention discloses a method for rapidly propagating chicory seeds in the Nanjing area. The rapid propagating method of the chicory seeds comprises the steps that nutrition buds of plants are picked in autumn, after cutting rooting, cultivation is conducted in a field, overwintering is conducted, and the seeds are harvested in the next year. Accordingly, cutting propagation is conducted on chicory plants in autumn, the seeds are harvested in the next year, the propagation method is simple, the harvested seeds do not have dormancy, and the seeds can be harvested in summer and then can be used for autumn sowing the same year.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a method for rapidly propagating chicory seeds. Background technique [0002] Chicory (Cichorium intybus L.) is an annual or perennial herb of the genus Cichorium (Cichorium L.) in the Compositae family. ", chicory (serial number 23) is included in the list of items that are both food and medicine. There are many kinds of chicory, among which the bud bulbs of softened chicory are the top grade among vegetables. They are widely planted and sold in Europe, the United States, Japan and other countries and regions, but there are only small-scale introductions in my country at present. [0003] Since most of the chicory seeds sold abroad are hybrids of the first generation, it is difficult to save seeds, and there are problems such as high prices, complex varieties, and large differences in traits, which are not conducive to direct large-scale introduction and cultivation. Therefore,...
