Problems solved by technology

But because the flowering period of autumn flowers and spring ripe fruits is in summer, the spring flowers and fruits on the lemon tree have reached saturation at this time, and are in the fruit expansion stage, and the existing branches are difficult to form flowers; High temperature and high humidity in summer will lead to vigorous vegetative growth of lemon trees, and it is difficult for lemon branches to form flowers and it is difficult to achieve the ideal yield

Embodiment 1

[0028] refer to figure 1 , This kind is applicable to the cultivation method of lemon autumn flowers and spring ripening, the steps are as follows:

[0029] S1. Fruit picking and pruning: in March-April, harvest all autumn flowers and fruits on the tree, and select unflowered shoots in different orientations for appropriate short cutting to promote branching; remove strong vegetative shoots in May-July , keep weak shoots;

[0030] S2. Fruit thinning and smearing: in May-June every year, remove spring flowers and fruits on weaker branches and branches with larger fruit volume. The number of spring flowers and fruits on each branch should not exceed 3, and fresh fruits should be removed from June to August. Wipe the tip of the non-flowered branch until a flower bud appears on the tip and stop the tip;

[0031] S3, fertilization: excavate the fertilization ditch in mid-October, apply slow-release compound fertilizer 600g, organic fertilizer 20kg, during the flowering stage to t...

Embodiment 2

[0036] refer to figure 1 , This kind is applicable to the cultivation method of lemon autumn flowers and spring ripening, the steps are as follows:

[0037] S1. Fruit picking and pruning: in March-April, harvest all the autumn flowers and fruits on the tree, and select immature branches in different directions for appropriate short cuts to promote branching; remove strong nutrients in May-July shoots, keep weak shoots;

[0038] S2. Fruit thinning and smearing: in May-June every year, remove spring flowers and fruits on weaker branches and branches with larger fruit volume. The number of spring flowers and fruits on each branch should not exceed 3, and fresh fruits should be removed from June to August. Wipe the tip of the non-flowered branch until a flower bud appears on the tip and stop the tip;

[0039] S3, fertilization: in mid-October, the excavation length is 100cm, the width is 40cm, and the fertilization ditch that the depth is 40cm, the slow-release compound fertiliz...

Embodiment 3

[0044] refer to figure 1 , This kind is applicable to the cultivation method of lemon autumn flowers and spring ripening, the steps are as follows:

[0045] S1. Fruit picking and pruning: in March-April, harvest all the autumn flowers and fruits on the tree, and select immature branches in different directions for appropriate short cuts to promote branching; remove strong nutrients in May-July shoots, keep weak shoots;

[0046] S2. Fruit thinning and smearing: in May-June every year, remove spring flowers and fruits on weaker branches and branches with larger fruit volume. The number of spring flowers and fruits on each branch should not exceed 3, and fresh fruits should be removed from June to August. Wipe the tip of the non-flowered branch until a flower bud appears on the tip and stop the tip;

Abstract

The invention discloses a cultivation method suitable for autumn flowering and spring ripening of lemons. The cultivation method comprises the following steps that fruit picking and pruning are carried out, specifically, in March to April, all autumn flowering and fruit on a tree are harvested, mature branches in different directions are selected, and proper cutting back is carried out to promote branching; in May to July every year, strong nutritional tips are removed, weak tips are retained, and fruit thinning is carried out; in May to June every year, spring flowers and fruits on weak branches and large-fruit branches are thinned, the number of the spring flowers and fruits reserved on each branch is not more than 3, tip wiping is carried out on newly-grown flowering branch tips in June to August, tip wiping is stopped until flower buds appear on the branch tips, fertilization is carried out, fertilization furrows are dug in the middle ten days of October, a slow-release compound fertilizer and an organic fertilizer are applied, and the compound fertilizer is applied from the flowering phase to the second physiological fruit drop period; and in May to July, the application amount of nitrogen fertilizer is controlled, phosphorus potassium fertilizer is additionally applied, slow-release compound fertilizer is topdressed twice in the fruit swelling period, and the like. The cultivation method suitable for the autumn flowering and spring ripening of the lemons can promote flowering of the lemons in summer, and the purpose that the autumn flowering and spring ripening fruits appear on the market in a centralized mode is achieved.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable planting, in particular to a cultivation method suitable for autumn flowers and spring ripening of lemons. Background technique [0002] Lemon (C.limon (L.) Burm.f.) is a fruit tree of the Rutaceae (Rutaceae) genus Citrus, because it is rich in fruit acid, vitamin C, limonin, flavonoids, volatile oil, orange peel Glycosides, etc., are recognized as healthy fruits in the world. At present, the planting area in my country exceeds 2.5 million mu. Lemons have the characteristics of flowering in four seasons. In tropical and subtropical regions, there are 3 batches of concentrated flowers and fruits a year (generally, 1-2 batches of flowers and fruits a year in the place of production), and spring flowers in February-March (8-9 monthly fruit picking), summer flowers in May-June (fruit picking in November-December), autumn flowers in August-September (mature in March-April: spring ripe fruit...
