Embodiment 1

[0022] Embodiment 1: a kind of greenhouse cutting method of European yew, comprises the following steps:

[0023] (1) Choose a place with flat terrain and sufficient water source to build a greenhouse, build a cutting pond with a length × width × height of 25m × 1.5m × 0.5m in the place where the seedlings are raised in the greenhouse, and set up a carbon dioxide pool and light-sensitive in the greenhouse. Automatic controller for seedling cultivation, automatic spray irrigation facilities are installed above the cutting pool, and a spray head is installed every 70cm above the cutting pool, which can spray and irrigate the cutting seedlings according to the light intensity. Management at the seedling stage;

[0024] (2) Fill the bottom of the cutting pool with magnetic powder to facilitate the drainage and ventilation of the cutting pool, which is beneficial to the growth of cutting seedlings and prevent the cutting seedlings from rotting. The amount of magnetic powder is 1 / 4 ...

Abstract

The invention discloses a greenhouse cuttage method of European yews. The greenhouse cuttage method includes the following steps of constructing a greenhouse, building a cuttage tank and a carbon oxide tank and arranging a light sensitive seedling controller in the greenhouse, arranging an automatic mist spray irrigation facility above the cuttage tank, filling magnetic powder and a cuttage medium in the cuttage tank, selecting twigs from a seed tree to be manufactured into cutting slips, inserting the cutting slips into the cuttage medium, finally performing cuttage seedling cultivation, strictly controlling sunshade degrees, temperatures and humidity in the greenhouse, and performing weeding and treatment of plant diseases and insect pests. By means of the greenhouse cuttage method, the European yews are high in rate of survival and short in fruiting time and can be rapidly bred and cultivated.

Description

technical field [0001] The invention relates to the technical field of agricultural plants, in particular to a greenhouse cutting method of European yew. Background technique [0002] Yew, also known as yew, is a plant in the genus Taxus. Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is recognized as a rare natural anti-cancer plant on the verge of extinction in the world. Due to the slow growth rate and poor regeneration ability of yew under natural conditions, there has not been a large-scale yew raw material forest base in the world for a long time. In 1994, yew was designated as a first-class rare and endangered protected plant by my country, and the United Nations also banned logging. It is a veritable "plant giant panda". [0003] Taxus has the following main values: 1. Economic value. In 2000, the price of high-quality paclitaxel in the international market was as high as 180,000 US dollars per kilogram. Taxus has s...
