Problems solved by technology

[0007] It has been reported that the "cup seedling method" of cultivating and transplanting loquat seedlings in the field uses a nutrient cup to fill in nutrient soil (soil, organic matter, fertilizer) to form a seedbed. The problem of high temperature stress in the cultivation and planting of grafted loquat seedlings, but it is still found that the seedlings are small and the root system is not developed enough. Before the third new shoots mature after planting, nearly half of the plants grow weakly and are in a slow seedling state. In the end, it can only slightly increase the early yield of loquat

Embodiment 1

[0033] A cultivation method for improving the early yield of loquat, comprising the steps of: (1) grafting loquat seedlings; 27 Degradable non-woven seedling bags, the cultivation substrate is packed into nutrition bags with non-woven seedling bags; 80 days after the loquat rootstock seedlings are grafted, the first new shoots and mature grafted seedlings appear, and they are dug out; Plant a grafted seedling in a seedling bag; put the nutrition bag and the grafted seedling into the seedling foam plate holes with a thickness of about 25cm and a hole diameter of about 15cm, and the distance of the grafted seedlings for false planting is 25cm; After 3 to 4 shoots, cultivate the loquat pseudo-plant bag seedlings; (5) transplant the loquat pseudo-plant bag seedlings to the field in situ, and plant them in December; (6) routinely manage the rapid growth period (21 months) and Flowering and fruiting period (6 months).

Embodiment 2

[0039] A cultivation method for improving the early yield of loquat, which comprises the following steps: (1) grafting of loquat seedlings; (2) building a shade shed with a height of about 2.0m, the same width as that of a nursery, and a shading rate of 40%; (3) 24× 27 Degradable non-woven seedling bags, the cultivation substrate is packed into a nutrition bag with a non-woven seedling bag; dig out the robust seedlings with one new shoot after grafting; plant a grafted seedling in each seedling bag after pruning; Nutrient bags and grafted seedlings are placed into the seedling foam plate holes with a thickness of about 25cm and an aperture of about 15cm, and the spacing between plants is 25cm; (4) the fake planting is cultivated for 9 months and after sprouting for 3 to 4 times, the bagged seedlings of loquat fake planting are bred; (5 ) Transplant the loquat pseudo-planted bag seedlings to the field in different places, plant in December, do not remove the seedling bag after t...

Embodiment 3

[0043] A cultivation method for improving the early yield of loquat, comprising the following steps: (1) grafting loquat seedlings; (2) building a shade shed with a height of about 2.2m, the same width as that of a nursery, and a shading rate of 40%; (3) using 24 ×27 degradable non-woven seedling bag, the cultivation substrate is packed into a nutrition bag with a non-woven seedling bag; dig out the robust seedlings that have matured once after grafting; plant a grafted seedling in each seedling bag after pruning; Put the nutrition bag and the grafted seedlings into the seedling foam plate holes with a thickness of about 25cm and an aperture of about 13cm, and the spacing between the plants is 25cm; (4) After the fake planting was cultivated for 7 months and germinated for 3 to 4 times, the bagged seedlings of loquat fake planting were bred; ( 5) Transplant the loquat pseudo-planted bag seedlings into the field on the spot, plant in October, do not remove the seedling bag, conv...

Abstract

The invention discloses a cultivation method for improving the early yield of loquat. In view of the problem of poor growth due to high temperature stress during the period of April to September during the cultivation period of grafted loquat seedlings and the first year of planting in the field; after the first mature shoots of loquat grafted seedlings, move to a shade with relatively low soil temperature and temperature. "False planting" is carried out in the shed, and the formula matrix is ​​used to promote the cultivation of "false planting bag seedlings" with developed roots in the shade shed; Damaged transplanting, after planting the field, there is no false live and slow seedling phenomenon, which avoids the inherent high temperature stress habit of loquat, and plays the role of quickly entering the rapid growth period of the canopy and lengthening the rapid growth period of the canopy. "False planting bag seedlings" makes it more convenient for loquat seedlings to be transported or transplanted in situ, and it is more conducive to cultivating a larger fruiting canopy after planting, thereby increasing the fruit yield of loquat orchards in the first year by about 1 times.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and in particular relates to a cultivation method for improving the early yield of loquat. Background technique [0002] The early yield of loquat orchards is closely related to the crown cultivation before fruiting. The larger the crown cultivated, the higher the yield. In the loquat production area in South China with superior light and heat resources, from seedlings grafting to fruiting in the orchard, it has experienced the grafted seedling cultivation period (12 months), seedling planting preservation period (9 months), crown rapid growth period (12 months), flowering 4 periods, including the fruiting period (6 months), took a total of 39 months. Among them, the cultivation period of loquat grafted seedlings and the survival period of seedling planting took a total of 21 months. Due to the high temperature stress during most of the growth period, the growth in the field was very small,...
