Introduction of planting technology of Torreya grandis!

Torreya grandis is the original tree species in China, also known as Chinese Torreya grandis, wild fir and concubine trees, which are currently planted in the south. What are its planting techniques?

Introduction to planting techniques of Torreya grandis

1. Land selection and preparation

Select high-quality fields with soft and breathable soil, rich in organic matter, flat terrain and fast drainage. When planting, we should first dig a large pit of 50-70 cm square and 35-50 cm deep, so that the soil is loose and conducive to the deep root system to absorb nutrients. The base fertilizer had better not be planted now, and the base fertilizer should be released one month in advance and then planted after fermentation.

two。 Planting density

When planting Chinese torreya seedlings, in order to stretch the roots of the seedlings, gently step on the soil while burying the soil, and gently lift the seedlings when the hole buries 70% of the soil, so that the root filaments stretch naturally in the soil. The initial planting density of afforestation is 33 plants / 667m2, and the plant row spacing is 4m × 5m.

3. Rational water and fertilizer

If the land is fertile, you can not apply fertilizer in that year, but if you want to apply fertilizer, it is better to choose the spring and autumn seasons every year, not to apply chemical fertilizer, let alone in summer. Fertilizing should be far away from the seedlings, and it is better to apply fertilizer at the periphery of the crown cover. If you can water appropriately in case of dry weather, Rain Water will gradually increase in summer, and the stagnant water should be drained immediately, otherwise the seedlings may die on a large scale.

4. Field management

Shaping and pruning: in order to achieve high and stable yield of Torreya grandis, the height and crown width of the tree must be controlled. The height of the crown should be controlled at 4-5m, and the crown width should be kept dry and round. Regular pruning is carried out every year after the canopy is fixed.

Loosening soil and weeding: from December to January in winter, combined with fertilization, the soil around Torreya trees is turned deep once, fallen leaves are buried in the soil, and the woodland is interplanted with legumes, grass and other crops to improve soil ventilation conditions and increase income. Turn it shallowly from July to August, and cut weeds and twigs to cover the rhizosphere of Torreya grandis, in order to cool down, moisturize and harvest.

Pest control: we should pay attention to the prevention and control of termites, Torreya grandis, gall mites, rust cochlea and other damage to Torreya grandis, spraying chemicals in advance.

The above is all about the planting technology of Torreya grandis. I don't know if you have any harvest!
