Cultivation method of bent cycad leaves

Abstract

The invention relates to a leaf bending culture method for a sago cycas, which comprises the following steps: in March or April, selecting a pot-cultured sago cycas which has a trunk thickness of 6-15 centimeters, a trunk height of 10-25 centimeter and 4-10 crown leaves, cutting away all the old leaves in a fair weather, and exposing in an outdoor open place; when new leaves of the sago cycas grow to 3 centimeters long, transferring a flower pot into a thin-film arched greenhouse, filling gravels and other similar substances under the pot to separate the pot from the soil surface, and prohibiting watering; when 2 / 5 of penniform lobes of the new leaves spread, and overwatering the rooting zone of the sago cycas once on the evening of that day to urge the leaves to quickly extend and spread; and when all the penniform lobes of the new leaves spread thoroughly, obtaining the pot-cultured sago cycas with the bent leaves. According to the invention, main environmental conditions are artificially regulated and controlled; the operating technology is simple, the culture time is short and the shaping process is easy; and the characteristics of low culture cost and high work efficiency are achieved, thereby obviously improving production and operation benefits. Besides, the method avoids the use of chemical agents, thus causing no pollution to the environment.

Description

(1) Technical field [0001] The invention relates to a method for cultivating bent cycad leaves. (2) Background technology [0002] Cycas, also known as Cycas revoluta (Latin scientific name Cycas revoluta Thunb.), is an evergreen woody plant belonging to the family Cycadaceae. It is an excellent ornamental tree species for potted or ground planting. In order to improve the ornamental value of cycads, people often cultivate them into "long iron", "short leaf iron" or "horn iron". "Short leaf iron" and "claw iron" are cycads shaped by leaves, usually potted cycads. At present, the methods of cycad leaf modeling are as follows: [0003] ① Cultivate "horn-style" cycads by tying new leaves with metal wires and adding chemicals: Dwarfing the leaves of cycads and proper shape treatment can make the leaves bend inward naturally, forming a small and beautiful "horn-style" cycads. In the new leaf stage of cycads, when the young pinnate compound leaves have not been put together, th...

Problems solved by technology

[0012] This method has the operation of root cutting and leaf cultivation twice a year, which is very different from other cultivation methods, and the degree of tenderness of the leaves is not quantified, so it is difficult to grasp the operation

This method also does not have the operation of blade artificial modeling
