Groundcherry seedling propagation method

Abstract

The invention relates to a groundcherry seedling propagation method which belongs to the field of groundcherry cultivation. The invention solves the problems that because groundcherry seeds are difficult to germinate, the yield of groundcherry plants bred from the seeds in that year is low and the levelness is poor, so that the seed reservation method of the groundcherry is the nutrition propagation method of rootstalk passed down from generation to generation, the yield of the groundcherry is reduced and the plant disease insect pest is severe. The method of the invention comprises the following steps: a seed is obtained from fruit, treated by gibberellin and off sleep, sprouted and planted in a seedling bed; a seedling which grows to have 7 to 9 leaves is permanently planted, fruit is picked after getting mature, and then underground rootstalk is left in the soil and dug out in late April in the next year, segmented to prepare a groundcherry seedling. Compared with the plant yield prepared through a method of root reserving in successive years, the total yield of groundcherry prepared by planting the groundcherry seedling of the invention is improved by 15 to 20 percent, the single fruit weight is improved by 8 to 10 percent, the sugar content is improved by 9 to 12 percent, the vitamin C content is improved by 5 to 10 percent, and root rot and other soil-borne diseases are reduced by more than 80 percent.

Description

technical field [0001] The invention relates to the field of red mushroom cultivation. Background technique [0002] Russula, scientific name Physalis alkekengi Linn., also known as golden lantern, lantern fruit, hanging golden lantern, bubble grass, is a perennial herb. The ripe fruit of Russula nigrum is bright red in color, sweet in taste, and delicious in fragrance. The fruit is rich in vitamin C, carotene, calcium, iron and other more than 20 kinds of minerals and 18 kinds of amino acids needed by the human body, as well as flavonoids and red pigments. It is not only an aromatic and sweet fruit, but also a nutritious tonic. It is a rare vegetable with both edible and health functions. [0003] Russula nigrum is distributed in the vast areas of my country except Tibet, and the resources are concentrated in the three northeastern provinces. In recent years, since the health function of the processed products made of red mushrooms has been recognized by more and more peo...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that due to the difficulty in germination of Russula nigrum seeds and the low yield and poor uniformity of Russula nigrum plants in those years when seeds were used for breeding, the way of saving Russula nigrum seeds is the vegetative propagation of rhizomes from generation to generation way, which in turn causes the problems of reduced output of Russula nigra and serious plant diseases and insect pests. Therefore, the invention provides a method for breeding Russula nigra seedlings
