Torreya grandis likes warm and humid climate and is relatively cold-resistant, so it is suitable for planting in the south of the Yangtze River. Torreya grandis has a long growth cycle, the seedlings can bear fruit in about eight years, and the maturity cycle is also long, and the fruit can mature once every three years. Therefore, it takes a long time to pick torreya grandis fruits and needs enough patience to maintain them.

Introduction to planting torreya grandis likes warm and humid climate and is relatively cold-resistant, which is suitable for planting in Jiangnan. It is required that the annual average temperature in the planting area should be 14- 17℃, and the accumulated temperature above 10℃ in one year should be above 8000 degrees. The lowest temperature in winter is higher than-15℃. In a year, the first frost period should be after the first ten days of 165438+ 10, and the final frost should be before the middle of March.

Torreya grandis has a life span of hundreds of years. Compared with its age, its fruit growth period is not too long. Many folks call Torreya grandis the centenary birthday star.

China is the country with the most precocious torreya grandis in the world. Torreya grandis is mainly concentrated in two mountain ranges in China. One is the Huiji Mountains, and the other is the Shogunate Mountains. According to records, there are 7 species of torreya grandis in the world, including 4 species in China, 2 species in the United States and 0 species in Japan.

Torreya grandis was planted for several years before bearing fruit. Torreya grandis has a long growth cycle, and seedlings can bear fruit in about eight years. At the same time, the ripening period is long, and the fruit can only ripen once every three years. Let's take a look at the detailed planting methods.

1, root cleaning: go to a special store to buy a few healthy seedlings, then remove the rotten parts of the roots and clean up the surface deteriorated objects.

2. Soil preparation: according to the number of saplings, prepare a suitable planting area, fill it with cultivated soil, which can be ordinary mountain soil, and then spray water to make the soil moist enough.

3. Planting: After the soil is ready, directly put the saplings in, cover the roots and fix them. Don't bury them all, but bury one third.

4. Post-curing: after planting, put it in the sun for a few days, water it every six hours, and new buds can be taken out in less than two weeks.

How long does it take to graft torreya grandis to blossom and bear fruit? Torreya grandis is difficult to cultivate and grows slowly. Grafted seedlings usually take about ten years to bear fruit. There are few fruits in the early stage, but much better in the later stage.

When will potted torreya grandis bear fruit? It takes a long time to pick potted torreya grandis from flowering to fruit maturity.

Why doesn't Torreya grandis knot 1? Torreya grandis did not bear fruit because it did not adapt to the environment. Torreya grandis is a tree that likes warm and humid environment. Not picky, just can't adapt to some extreme environments, such as high altitude and mountains. Torreya grandis may take a long time to get used to it.

2. It may also be due to insufficient nutrition. For torreya grandis, nutritional supplement is extremely important. Fertilizer and water management is very important to achieve the goal of early fruiting, high yield, stable yield and high quality of torreya grandis. If there is not enough nutrition, it will not bear fruit.

Key points of high-yield cultivation techniques of torreya grandis 1. Tending management: Torreya grandis is easy to be burned, so in the first year of planting, cooling measures should be taken in summer, and awnings should be set up in the orchard to shade Torreya grandis from the sun. Mesh materials should be used to build the sunshade, so that the sunshade is transparent.

2. Fertilizer and water management: Torreya grandis needs a lot of nutrients and water, so fertilization and irrigation should be carried out in time, especially in summer, because the temperature is high for a long time, the water in the soil is easy to evaporate. In order to ensure sufficient water in the soil, it is necessary to cover the roots of torreya grandis with a layer of weeds to reduce water evaporation.

3. Pruning and shaping: In order to improve the fruiting rate of torreya grandis, it is necessary to trim and shape torreya grandis trees properly and control the height and branch length of torreya grandis trees. Proper pruning shall be carried out to ensure that the crown height of torreya grandis is between 4m-5m and 5 m, and then proper pruning shall be carried out after plastic surgery to cut off delicate, diseased and dense branches.

4. Loosening and weeding: Loosening is to improve the permeability of soil and promote the growth of torreya grandis root system, while weeding is to avoid the consumption of nutrients and water and ensure that torreya grandis can absorb enough nutrients and water, so loosening and weeding is essential during torreya grandis planting.

5. Pest control: Once pests and diseases appear, the growth of torreya grandis will be greatly affected. The most common pests and diseases are torreya grandis, rust snails and termites. Pesticides are needed to prevent and control pests and diseases. Each disease and insect pest has a special pesticide, which only needs to be sprayed with torreya grandis in proportion.
