Detailed Explanation of Torreya Planting Management and Maintenance Techniques

Torreya, commonly known as the "concubine tree," is a tree species native to China and a rare economic tree species in the world. It mainly grows in the humid environment of the south. It is primarily distributed in areas such as Anhui and Zhejiang in China. Torreya is grafted from wild torreya trees. With the discovery of its nutritional value, its economic value has become increasingly high, and it has become a poverty alleviation project in places such as Anhui and Zhejiang. Torreya has a three-year growth period, during which many problems occur and careful management is required. Below is an introduction to the management and maintenance techniques needed when planting torreya.

1. Tending Management

In the first year after planting, the most important task is to do a good job of drought resistance, cooling, and seedling protection during the high summer temperatures. The torreya tree is a tree species relatively prone to sunscald damage, so a shade shed should be built to shade the tree body. The shade shed is best made of net-like material, because this can not only provide shade but also not hinder light transmission inside the shed. In winter, measures should be taken to prevent torreya from frost damage. During the second tending, some weeds can be used to cover the root area of the tree body to keep the roots warm. After spring arrives, bury the weeds into the soil to prevent pests and diseases, and they can also serve as fertilizer for the tree. At least two tendings should be carried out on the tree body each year, one in summer and one in autumn. Do not dig deeply and damage the roots, to prevent soil erosion. Tending can be carried out together with fertilization, and organic fertilizer should be used as much as possible.

2. Water and Fertilizer Management ⟧7⟧Torreya has a relatively large demand for water and fertilizer during its growth process. In August each year, carry out a comprehensive tending operation in the garden, and the methods of hole tending and cutting tending can continue to be used. Use weeds to cover the root area of the tree body to reduce water evaporation caused by high summer temperatures. Growers with the conditions can establish an irrigation system in the garden and spray the needed fertilizer and water through the irrigation system in the garden. The irrigation system is best to use drip irrigation. Each spring, apply organic fertilizer comprehensively once, preferably farmyard manure. The fertilizer must be fully decomposed, and the fertilizer should be buried in the soil.

Torreya grandis has a relatively high demand for water and fertilizer during its growth process. Every year in August, carry out a comprehensive tending operation in the orchard, and the methods of hole tending and slash tending can continue to be used. Cover the base of the trees with weeds to reduce water evaporation caused by high summer temperatures. Growers with the means can establish an irrigation system in the orchard, spraying the needed fertilizer and water through the irrigation system in the orchard, and it is best to use drip irrigation for the irrigation system. Each spring, apply a comprehensive application of organic fertilizer, preferably farmyard manure; the fertilizer must be fully decomposed, and the fertilizer should be buried in the soil.

3. Shaping and Pruning ⟧9⟧To increase the yield of torreya, shaping and pruning are indispensable. To achieve high and abundant yields of torreya, the height and branches and leaves of the torreya tree must be well controlled. If the tree grows too tall, its demand for nutrients will become higher, and it will be unable to bear fruit, wasting fertilizer in vain. Being too tall will also cause certain difficulties for picking, but if it grows too short, the fruiting rate will decrease. Therefore, after the torreya trees form a forest, the tree bodies should be properly pruned. The height of the crown should not be lower than 4 m or higher than 5 m. The crown width should maintain multiple trunks. After taking shape, it should still be pruned, cutting off overly dense, thin and weak, and diseased branches.

To increase the yield of Torreya grandis, shaping and pruning are essential. To achieve high and abundant yields of Torreya grandis, the height and branches and leaves of the Torreya grandis trees must be well controlled. If the tree grows too tall, its demand for nutrients becomes greater, and it will fail to bear fruit, wasting fertilizer for nothing. Being too tall also makes harvesting somewhat difficult, but if it grows too short, the fruiting rate will decline again. Therefore, once the Torreya grandis trees form a forest, the trees should be pruned appropriately, and the height of the crown should not be less than 4 m or more than 5 m. Maintain a multi-trunk crown width, and after the shape is formed, continue pruning by cutting off overly dense, thin and weak, and diseased branches.

4. Loosening Soil and Weeding ⟧11⟧Loosening soil and weeding is also an indispensable part of planting torreya trees. Loosening the soil allows the tree roots to spread and extend better, but be careful not to dig and break the tree roots when loosening the soil. If the tree roots are broken, it will have a certain impact on the tree body's nutrient absorption and will also reduce the final yield. Weeding is to prevent some weeds from competing with torreya seedlings for nutrients, water, and sunlight. In winter, the soil around the tree can be fully plowed once in combination with fertilization. Planting some legume crops around it can not only improve soil permeability but also be turned into the soil as fertilizer like weeds.

Loosening the soil and removing weeds is also an indispensable part of planting Torreya grandis trees. Loosening the soil allows the tree roots to spread and extend better, but be careful never to break the tree roots when loosening the soil. If the tree roots are broken, it will have a certain impact on the tree's nutrient absorption and will also reduce the final yield. Weeding is to prevent some weeds from competing with Torreya grandis seedlings for nutrients such as nutrients, water, and sunlight. In winter, combined with fertilization, the soil around the trees can all be plowed once. Planting some legume crops around them can not only improve the permeability of the soil, but can also be turned into the soil as fertilizer just like weeds.

The above are the management and maintenance techniques for planting torreya trees. Torreya trees take a relatively long time to grow, so farmers need patience and care. Special attention should be paid to pests and diseases that may occur during this period, such as termites and torreya leaf roller moths. These will greatly reduce the yield of torreya, and if not handled in time, they can lead to total crop failure in severe cases.
