A kind of nutritive cube cultivates the method for oil tea seedlings
Technical field:
The present invention relates to camellia seedling technical field, particularly relate to a kind of method that nutritive cube cultivates oil tea seedlings.
Background technology:
In recent years, camellia oleiferaindustry obtains the attention of each side, also achieves significant progress simultaneously, but also there are some problems, and the problem that newly-built camellia oleifera lam survival rate is low has just had a strong impact on the speed of afforestation and the enthusiasm of enterprises and individuals.Current oil tea afforestation is all select 1 ~ 2 year raw seedling to transplant, and the survival rate of afforestation is very undesirable, and survival rate is less than 60%, and particularly bareroot seedling, once rainfall not in time, just has dead danger.Along with the development that oil tea produces, the requirement of afforestation unit to nursery stock specification is tending towards variation, and some enterprises may be ready that increase nursery stock in early stage is dropped into, application seedlings are planted, to reach the objects such as the time reducing young growth and manage, the turnaround time shortening fund; The north area such as Yangze river and Huai river development oil tea, seedling easily produces freeze injury, uses seedlings also can reduce freeze injury in seedling stage strong sprout; In addition, low production forest and newly make the demand that young growth woods also has seedlings after-culture.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of convenient management, can improve survival rate, and the nutritive cube of the time reducing young growth management and the turnaround time shortening fund cultivates the method for oil tea seedlings.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Nutritive cube cultivates a method for oil tea seedlings, it is characterized in that: comprise the following steps,
High about the 40 ~ 50cm of preparation (1) alms bowl of nutritive cube, bore 20 ~ 30cm, osculum is arranged at side or bottom; Nutrition Soil should select P in soil H value be 5.5 ~ 6.5 the fertile yellow soil of subacidity or paddy soils; The Nutrition Soil of every cubic metre can add the dish cake that becomes thoroughly decomposed of 1.5 ~ 3.0kg, the fused calcium magnesium phosphate of 3 ~ 5kg and, 0.5 ~ 1kg composite fertilizer, ready Nutrition Soil is loaded in nutritive cube, every alms bowl soil loading amount is to fill as principle, fitly be placed on seedbed by the alms bowl filling Nutrition Soil, the width put is no more than 1.0m;
Field planting: choose healthy and strong anosis 1 year raw nursery stock transplantation with soil in nutritive cube in winter-spring season after the preparation of nutritive cube, water sufficient normal root water, native face upper cover a layer thickness is the straw of 2 ~ 5cm, presses skim soil again above straw;
Management: mend fertilizing of biogas manure, composite fertilizer and foliage fertilizer in time depending on nursery stock growing way, note watering, avoids the generation of anthracnose, soft rot and freeze injury;
Go out garden: in November investigate 4 years raw nursery stocks quantity, highly, leading thread, carry out seedling sorting process, require that height of seedling is at more than 80cm, leading thread, at more than 1cm, has 2 ~ 4 thick branches and leaves, healthy and strong disease-free, during lifting, in nutritive cube, root out the native seedlings of band, require not hinder root, transport with trolley after wrapping.
All callus plastics will be smeared to wound during described lifting.
After described transplanting, when continuous sunny high temperature, tree crown and trunk are sprayed water or the rising agent of spray suppression.
The invention has the beneficial effects as follows: convenient management of the present invention, can improve survival rate, reduce the time of young growth management and shorten the turnaround time of fund, be also adapted at the colder area of weather and transplant, survival rate is to more than 95%.
Embodiment:
The present invention is further illustrated below by embodiment.
Nutritive cube cultivates a method for oil tea seedlings, comprises the following steps,
The preparation of nutritive cube: alms bowl height about 50cm, bore 30cm, osculum is arranged at side or bottom; Nutrition Soil should select P in soil H value be 6 the fertile yellow soil of subacidity or paddy soils; The Nutrition Soil of every cubic metre can add the dish cake that becomes thoroughly decomposed of 2kg, the fused calcium magnesium phosphate of 4kg and, 0.8kg composite fertilizer, ready Nutrition Soil is loaded in nutritive cube, every alms bowl soil loading amount is to fill as principle, and be fitly placed on seedbed by the alms bowl filling Nutrition Soil, the width put is no more than 1.0m;
Field planting: choose healthy and strong anosis 1 year raw nursery stock transplantation with soil in nutritive cube in winter-spring season after the preparation of nutritive cube, water sufficient normal root water, native face upper cover a layer thickness is the straw of 3cm, presses skim soil again above straw;
Management: mend fertilizing of biogas manure, composite fertilizer and foliage fertilizer in time depending on nursery stock growing way, note watering, avoids the generation of anthracnose, soft rot and freeze injury;
Go out garden: in November investigate 4 years raw nursery stocks quantity, highly, leading thread, carry out seedling sorting process, require that height of seedling is at more than 80cm, leading thread, at more than 1cm, has 2 ~ 4 thick branches and leaves, healthy and strong disease-free, during lifting, in nutritive cube, root out the native seedlings of band, require not hinder root, transport with trolley after wrapping.
All callus plastics will be smeared to wound during lifting.
After transplanting, when continuous sunny high temperature, tree crown and trunk are sprayed water or the rising agent of spray suppression.
The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
