Latest summary of precautions for Torreya grandis cultivation
Torreya grandis (Chinese torreya) is an evergreen tree, a grafted tree, and can grow to about 20 m when growing most vigorously. The fruit of Torreya grandis is very rich in nutritional value, crisp and tasty, with a strong aroma. It is a fruit with comprehensive development and utilization value combining health care and medicinal use, and the kernels of Torreya grandis can also be eaten after being roasted, making it one of the more common dried fruits today. Now Torreya grandis has gradually become one of the projects for many people to escape poverty and become rich. Below, follow the editor to take a look at the cultivation methods for Torreya grandis!
1. Deep digging and shallow planting
Although the roots of Torreya grandis are somewhat shallower than those of other trees, once it grows and develops, they also become very deep and extensive. Before planting, dig a deep pit at least 0.5 m wide and 0.5 m deep. Make the soil loose, which is beneficial for root growth and development and nutrient absorption; this is the deep digging for Torreya grandis. Shallow planting is determined by the characteristic that Torreya grandis is particularly afraid of water, because water accumulation can greatly hinder the development of Torreya grandis. Therefore, when planting, the depth must not exceed the depth at which the sapling was in the soil, so it can be slightly higher than the soil or level with the soil.
2. Lift gently and tread firmly
When planting, while filling the soil, tread the soil gently and firmly as you bury it. When the hole has been filled to two-thirds, slowly lift the sapling. Let the Torreya grandis sapling grow and extend naturally in the soil. After doing this, fill the pit full, preferably until it is slightly higher than the orchard ground. Then tread the soil gently and firmly. Do not compact it with tools such as a hoe, because this has a great impact on the roots and can cause the root filaments in the soil to break upon contacting sand and stones, making them unable to absorb nutrients and affecting the plant's nutrient absorption. In hot weather, water frequently, which can increase its survival rate.
3. Reasonable fertilization
When planting Torreya grandis, generally do not apply base fertilizer and plant at the same time. About 30 days before planting, apply sufficient base fertilizer to the orchard and let the base fertilizer fully ferment. Wait until the base fertilizer has completely fermented before planting. Of course, if the soil is fertile enough, no fertilizer is needed in the year of planting. It is best to fertilize twice a year, once in spring and once in autumn. Note that chemical fertilizers should not be applied, and fertilization is even more unsuitable in summer. When fertilizing, stay as far away from the saplings as possible, because the roots of Torreya grandis are fleshy roots. If they receive too much fertilizer, the root cells may be burned to death, affecting the survival rate.
4. Diligent management
When cultivating Torreya grandis, the first thing to pay attention to is weeding, because some weeds compete with young Torreya grandis trees for water, nutrients, sunlight, and so on. However, in the hot summer, do not use agricultural tools such as hoes to weed, because this may injure the roots of Torreya grandis, and loosening of the soil around the roots can directly cause the death of the saplings. Therefore, in summer, weeds should be pulled by hand, and the pulled weeds can be used to cover the roots. This can not only shade the roots but also serve as fertilizer. For seedlings, also pay attention to feeding by animals such as hares and goats.
The above are the precautions to note when planting Torreya grandis. The trunk of Torreya grandis is large, but it is relatively fragile during the seedling stage, so everyone must pay attention to the relevant precautions during the seedling stage. Especially when planting in the field, make the soil soft enough, give the roots sufficient space to grow, and strengthen orchard management to improve the survival rate and yield.
