Cultivation method for promoting head separation of cycas revoluta

Abstract

The invention discloses a cultivation method for promoting the head separation of cycas revoluta. In any season of the year, cycas revoluta growing robustly is selected, a long and narrow disinfectedknife is used for cutting meristem of terminal buds of cycas revoluta away, the smaller wound surface is better, cut is neat and smooth, after cutting, the cut is sealed with paraffin at once or naturally dried, and then cycas revoluta is cultivated in the warm and moist environment in which sunshine is abundant. In the cultivation process, watering and fertilization are conducted according to theactual condition of the soil, except of normal water and fertilizer management in the growth season, the cycas revoluta is watered with enough water until water flows out from the bottoms of pots, secondary watering is conducted until the surface layer and middle layer of soil are dried, and the situation that water is accumulated at the roots and thus the roots are rotten or infected by pathogenic bacteria is prevented. According to the method, normal single-head cycas revoluta is cultivated into fasciculate multi-head cycas revoluta, when symmetrical multi-head cycas revoluta needs to be cultivated, only redundant buds need to be removed, and when complex multi-head cycas revoluta needs to be cultivated, only once technical transformation needs to be conducted on differentiated buds. The operation is rapid and simple, the cultivation cost is low, and after single-branch turns into multiple heads, not only is the ornamental value greatly improved, but also the economic value increases several times over.

Description

Technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a cultivation method for promoting the separation of cycads. Background technique [0002] Cycas (cycas revoluta), commonly known as cycad, is a gymnosperm belonging to the cycas family of evergreen arbores. The stem of the cycas is sturdy and erect, brown-black in color, and has no branches beside it. The large, feather-like compound leaves clustered on the top of the stem, the length can reach 0.5~2m, and it looks like a green leather engraved. The flowers are unisexual. There is no perianth outside, and the male and dioecious flowers are different. The leaves of female plants grow larger than male plants. The female peanut is on the top of the stem, 9-12cm long, gray-green when it first opens, and then turns brown. The female flower can bear fruit. It is as big as a peach, cream-colored, and has a smooth skin. It usually blooms from June to July and the seeds m...

Problems solved by technology

The truncation method is to cut off the top of the trunk to promote the differentiation of buds, but the trauma surface is large, which has a great impact on tree vigor and ornamental, and is only suitable for larger cycads; the oblique planting method is to make full use of the upward growth characteristics of cycads to promote buds. Differentiation has no effect on small trees that have not formed a trunk; the splicing method is to combine two or more cycads by joining together, and the assembly method is just a few cycads simply planted together, not a real multi-headed cycad ;The double embryo method is to use the seeds with double embryos to reproduce and form two connected cycads. It is sexual reproduction and it is difficult to obtain seeds; Cycad
