Abstract

The invention belongs to the technology of plant growing and cultivating and particularly relates to a method for cultivating torreya grandis. Firstly, a proper torreya grandis cultivating field needs to be selected, transplantation can be carried out after torreya grandis seedlings are cultivated, and plants need to be managed after transplantation is completed. According to the method for cultivating the torreya grandis, large-scale and large-area cultivation of the torreya grandis can be achieved, cultivation investment is little, benefits are high, propagating plants are high in survival rate and survive easily, the bud forming year is early, and the high quality and high yield performance is strong.

Description

A kind of implantation methods of Chinese torreya

Technical field

The invention belongs to planting culture technique, relate in particular to a kind of implantation methods of Chinese torreya.

Background technology

Chinese torreya fruit is nutritious, local flavor is aromatic, having health care, medical value and comprehensive development and utilization is worth, Chinese torreya is generally by using after frying, Chinese torreya kind benevolence is after frying, and crisp-fried is good to eat, is nutritious first-class dry fruit, on existing market, the output of Chinese torreya is not high, is mainly because Chinese torreya plantation does not reach industrialization.

Chinese torreya industrialized development face mainly faces following 2 problems:

1, Chinese torreya is dioecian plant, traditional management style for a long time, particularly last century six, the seventies, because plantation family lacks scientific knowledge, because of male Chinese torreya not result but there is the feature that material is good, self-employed tree cultivator protects consciousness not enough, a large amount of male Chinese torreyas are cut down, cause good male Chinese torreya kind resources loss, in planting process, Chinese torreya arillus is deposited in Chinese torreya usage tree root in a large number, thereby cause germ and damage by disease and insect, cause a large amount of Chinese torreya trees to be grown in shrub throughout the year, in mao bamboo woods, be uncultivated state, forest land health is poor, causing can not ventilative printing opacity, output declines year by year, diseased plant is increased, the production of Chinese torreya is plummeted.

2, newly make that Chinese torreya woods growth is slow, survival rate is low, solid late, investment is large, return late, thereby restricted the large area development of these improved seeds of Chinese torreya.

Summary of the invention

Realize for solving Chinese torreya plantation in prior art the problem existing in industrialization process, the invention provides a kind of implantation methods of Chinese torreya.

The technical solution used in the present invention is: 1, a kind of implantation methods of Chinese torreya, is characterized in that adopting following steps:

The selection of A, Chinese torreya planting site: height above sea level 200-700m, it is fertile that the soil is porous, and the sandy soil that the content of organic matter is abundant is advisable with hill Schattenseite, ditch valley floor, avoids air port, and soil depth is more than 60cm, and the thickness of topsoil is greater than 30cm;

B, kind are selected: select south, Anhui rice Chinese torreya to do stock, the thin Chinese torreya of high yield, stable yields, high-quality, as scion, is cultivated clone Chinese torreya nursery stock;

C, transplanting:

(1) transplanting time: annual 9-12 month or 2-3 month;

(2) Chinese torreya selection of seedling: choose the Chinese torreya nursery stock that nursery stock is sturdy, root system is complete, disease-free;

(3) dig cave: taking the planting hole time is selected in and carries out in 9-10 month, and the specification of planting hole is 100cm*100cm*60cm, and planting hole is pressed isosceles triangle configuration, applies base fertilizer in cave wholely;

(4) transplant: Chinese torreya nursery stock is pressed seeding row spacing 4m*4m, 5m*5m or 5m*6m arrange planting density, when plantation, configure the strain number of male Chinese torreya nursery stock by the 3%-5% of female Chinese torreya nursery stock strain number, male Chinese torreya seedling growth is at the uptake place of planting site, be selected in rainy day or cloudy day and Chinese torreya nursery stock root band ball transplanting, the front first backfill of the Chinese torreya nursery stock of planting, the real planting hole of compacting, making the height between the interior native surface of planting hole and ground surface soil is 5-6cm, plant into Chinese torreya nursery stock reclaimed soil, the height of reclaimed soil is higher than ground surface soil 5-10cm, tread after backfill soil, water immediately to saturating root,

D, plant management: Chinese torreya nursery stock need to complete the laying of shade net between 4-5 month, selecting light transmittance is that 50% shade net shelters from heat or light, after transplanting the 6-9 month of First Year and Second Year shelter from heat or light in 6-9 month, between at the beginning of by the end of June to 7 month, need to cover with withered grass the bottom surface of Chinese torreya nursery stock surrounding, annual fertilising 1-2 time, adopt circular groove method to childhood Chinese torreya sapling apply fertilizer, every strain Chinese torreya nursery stock nitrogen fertilizer application 50-100g, composite fertilizer 100-150g, fertilizer 5-15g, after transplanting, Second Year Chinese torreya nursery stock fertilising point need to apply fertilizer in the soil beyond trunk 50cm.

Beneficial effect of the present invention is: the present invention can realize Chinese torreya scale establishing in large scale, plantation small investment, and high efficiency, Propagated Plantlets survival rate is high, is easy to survive, and forms the bud time early, and high grade producing performance is strong.
