Problems solved by technology

In loquat production, 2-3 year-old nutrition bags or bare-root grafted seedlings are generally planted when the garden is built (rootstock seedlings are 1-2 years old, and 1 year after grafting); because of the long seedling age and large seedlings, in order to ensure the survival rate of colonization When transplanting, it is necessary to cut off the top shoots and 1 / 3-1 / 2 of each leaf to reduce the loss of water caused by leaf transpiration; and the roots of large seedlings are easily damaged during transplanting, especially bare-rooted seedlings The root system is more susceptible to damage, which affects the survival rate; in order to achieve the purpose of dwarfing the canopy, the excessively high branches are generally cut off to fix the trunk, which consumes a lot of growth of branches and leaves

Embodiment 1

[0035] In April-May, take a nutrient bag with a diameter of 10-20cm, and sow 2-3 full-grained 'Jiefang Zhong' loquat seeds in each nutrient bag; when the seedling grows 2-3 true leaves, Execute mass concentration 0.2-0.3% commercial compound fertilizer and water fertilizer once every two weeks; When the seedling grows to a height of 7-10cm, thin out the weak seedlings, and leave 1 strong rootstock seedling in each nutrient bag; From January to March of the following year, select seedlings with a height of 10cm ± 2cm and a stem diameter ≥ 0.6cm, leave 2-5 leaves under the interface, and graft the 'Yanhong' variety by cutting grafting, and remove the rootstock buds in time after the grafting survives; When the sprouts grow to 5-10cm, the seedlings are transplanted and planted;

[0036] 2 months before planting, prepare a planting hole with a length of 80-100cm, a width of 80-100cm, and a height of 60-80cm, and apply 15kg ± 2kg of organic fertilizer in layers in each planting hol...

Embodiment 2

[0041] Compared with Example 1, the difference of this embodiment is: the loquat varieties grafted and planted are different, and the present embodiment is 'Zaozhong No. 6' loquat variety; when the seedling grows 2 to 3 true leaves, Apply water and fertilizer with a mass ratio of decomposed human and animal manure to water of 1:20 every half a month.

Embodiment 3

[0043]Compared with Example 1, the uniqueness of this example is that the loquat varieties that are grafted and planted are different, and this example is the 'Xinbai No. 1' loquat variety; when the seedling grows 2-3 true leaves, each Apply a water fertilizer with a mass ratio of cooked peanut cake fertilizer to water of 1:20 every half a month.

Abstract

The invention provides a cultivation method for putting planting loquat grafting shoots into production in advance. The cultivation method comprises the following steps of nursery stock cultivation, planting pit preparation, seedling planting and management after planting. The cultivation method is characterized in that a period from nursery stock sowing to outplanting is within one year and is shorter than a traditional seedling culture period by 1-2 years; and in addition, during nursery stock planting, roots, branches and leaves are not damaged, so that after nursery stock planting is carried out, a rejuvenation period is short, a planting survival rate is high and a way crops are growing is tidy. In addition, by use of the cultivation method disclosed by the invention, after planting is carried out, time for forming a crown which is put into production is shortened to two years, and is shortened by more than one year than the time for traditional plantation big seedlings to be put into production, i.e., by use of the cultivation method disclosed by the invention, the crown can be relatively quickly formed, and therefore, loquat saplings can be put into production in advance so as to shorten a garden building period, i.e., reduce garden building years and lower garden building cost.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a cultivation method for planting loquat grafted young seedlings and putting them into production early. [0003] 【Background technique】 [0004] Loquat is a characteristic evergreen fruit tree in southern my country. The fruit matures in late spring and early summer. It is sweet and sour, and is very popular among consumers. In loquat production, 2-3 year-old nutrition bags or bare-root grafted seedlings are generally planted when the garden is built (rootstock seedlings are 1-2 years old, and 1 year after grafting); because of the long seedling age and large seedlings, in order to ensure the survival rate of colonization When transplanting, it is necessary to cut off the top shoots and 1 / 3-1 / 2 of each leaf to reduce the loss of water caused by leaf transpiration; and the roots of large seedlings are easily damaged during transplanting, especia...
