Problems solved by technology

[0006] These methods have obvious advantages, but the cutting seedlings cultivated have only one main stem, and there is still only one main stem after being transplanted to the field. The effective number of newly planted ramie plants is small, there are many high-level branches, it is difficult to peel off the bast, and the broken stems cannot be harvested. Stripping, the new hemp can only harvest one season of hemp a year, the output of raw hemp is low, and the fiber quality is poor. Destroy the old hemp garden

example 1

[0023] [Example 1] The variety is "Xiangzhu No. 3". According to the requirements of ramie cutting seedlings, the seedling filming facilities are prepared, the seedbed is fully moistened, and the ramie main stem tip or branch tip with a length of about 10cm is cut on July 15. , first cut off the 2 leaves at the base of the cuttings, then cut off the top growth point of the upper stem section, keep 3 to 4 leaves in the middle of the cuttings, cut them directly in the prepared seedbed, and manage the seedbed stage according to the conventional cutting propagation technology of ramie , so that the cuttings grow new roots and branches, and the first-level branches are cultivated into ramie low-level branch cutting seedlings. Take the seedlings for deep planting on August 5. When the cutting seedlings grow 3 to 4 branches and the average length of the branches is greater than 2cm, pick the seedlings in the afternoon on a cloudy or sunny day, and transplant them in the planting ditch...

example 2

[0024][Example 2] The variety is "Tril", and the cutting seedlings were raised on March 2. According to the requirements of ramie cutting seedlings, the seedling filming facilities were prepared, the seedbed was fully moistened, and the main stem tips or branches of ramie with a length of 12-15 cm were cut. Cut off the 1-3 leaves at the base of the cuttings, cut them directly in the seedbed, and manage the seedbed stage according to the conventional cutting propagation technology of ramie. When practicing seedlings, cut off the top of the surviving cutting seedlings, keep 3 to 4 leaves at the base, and cultivate the first-level branches of the cuttings into ramie low-level branch cutting seedlings. When the seedlings grow 3 to 4 branches and the average length of the branches is greater than 2cm, take the seedlings in the afternoon on a cloudy or sunny day, transplant them in the planting ditch with soil, plow the hemp field before transplanting, and apply three-component compo...

example 3

[0025] [Example 3] The variety is "Xiangzhu No. 3". According to the requirements of ramie cutting seedlings, the seedbed covering facilities are prepared, the seedbed is fully moistened, and the young stems with 2 to 4 leaves are cut off, and the base leaves are cut off first. , retain the upper 1 leaf, cut directly in the seedbed, and manage the seedbed stage according to the conventional cutting propagation technology of ramie. When the branch length of the stem segment is greater than 5cm or when there are 3 to 5 leaves, the growth point of the branch is removed to make the axillary buds of the branch germinate and grow to form secondary branches, and the secondary branches are cultivated into low-level branches. Branch cuttings. Take the seedlings for deep planting on May 15. When the cutting seedlings grow 3 to 4 branches and the average length of the branches is greater than 2cm, pick the seedlings in the afternoon on a cloudy or sunny day, transplant them in the planti...

Abstract

The present invention relates to the topping and stem planting propagation of ramie and the seedling period management of low position ramified seedling in field. During stem planting propagation of ramie, the stem is topped while planting or while hardening-off after planting; or, the tender stem is cut into section and stem planted to grow seedling, and after the branches are formed, the growth point is eliminated and the low position ramified seedling is cultivated via secondary branching cultivation. The low position ramified seedling is planted deeply in field and promoted to grow independent root system via intertillage and earthing, so as to form new plant. The said propagation process can promote the growth of root system and rhizome and has obvious features of high yield, high quality and high efficiency.

Description

technical field [0001] The invention relates to a ramie cultivation technique, in particular to a method for cultivating ramie low-position branch cutting seedlings and field seedling stage. Background technique [0002] Ramie can reproduce both by seed and vegetatively. The propagation speed of ramie seeds is fast and the cost is low. However, the genes of existing ramie varieties are highly heterozygous, and there is serious segregation and variation in the offspring population of seed propagation. Low, poor fiber quality. The vegetative propagation of ramie, that is, the use of ramie underground stems (commonly known as seed stems or roots) and aboveground stems for propagation is an important method to maintain the purity and excellent characteristics of ramie varieties. Underground pests and diseases, inconvenient transportation and high cost cannot meet the needs of rapid development of ramie production and rapid promotion of fine varieties. In order to further impr...
