A kind of cultivation method for promoting the splitting of cycads

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 splitting of cycads. Background technique [0002] Cycas revoluta (cycas revoluta), commonly known as cycas, is a gymnosperm plant belonging to the evergreen tree of Cycadaceae. The stem of cycas revoluta is thick and upright, brown and black in color, without branches. The pinnate large compound leaves clustered on the top of the stem can reach 0.5-2m in length, and are carved like green leather. Flowers unisexual. There is no perianth outside, and male and female flowers are dioecious. The leaves of female plants are larger than those of male plants. Female flowers are born on the top of the stem, 9 to 12 cm long, gray-green when first blooming, and then turn brown. Female flowers can be firm. Round as big as peach, beige red, smooth skin. Usually blooms from June to July, and the seeds mature in 10 months. Cycas grow...

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
