Fertilization method for citrus sinensis 'blood orange' planting

Abstract

The invention discloses a fertilization method for citrus sinensis 'blood orange' planting. The fertilizing method for blood orange planting comprises the following steps of carrying out fertilizationfor at least three times every year from the first year in the beginning of spring, autumn and later period of winter every year after blood orange seedlings are transplanted to survive, wherein an organic fertilizer, a nitrogen phosphorus and potassium compound fertilizer and a water-soluble fertilizer are applied for every plant every time, and the fertilization mode is as follows: forming an annular dressing furrow by taking each citrus sinensis 'blood orange' plant as the center of a circle, sprinkling uniformly mixed organic fertilizer and nitrogen phosphorus and potassium compound fertilizer into the annular dressing furrows, covering the annular dressing furrows with improved soil and topsoil successively, and then applying the water-soluble fertilizer; in a fruit bearing period ofcitrus sinensis 'blood orange', spraying a potassium dihydrogen phosphate leaf fertilizer; and in a citrus sinensis 'blood orange' fruit expanding later period, spraying a calcium hydrogen phosphateleaf fertilizer. The fertilization method for citrus sinensis 'blood orange' planting meets the demand on water and fertilizer for citrus sinensis 'blood orange' planting, and the annular dressing furrows are covered by the improved soil after fertilization, so that soil hardening is avoided and the fertilizers are absorbed by the plant favorably. The planted citrus sinensis 'blood orange' is goodin taste, enough in water and free of conditions of dehiscent fruits and dry core fruits.

Description

technical field [0001] The invention relates to the technical field of fruit planting, in particular to a fertilization method for planting blood oranges. Background technique [0002] Blood orange (scientific name: Citrus sinensis 'blood orange') is a cultivar plant of sweet orange under the Rutaceae Citrus genus. Trees, branches few or nearly thornless. The leaves are usually slightly smaller than pomelo leaves, the wing leaves are narrow and long, the leaves are ovate or ovate-elliptic, rarely lanceolate, the flowers are white, rarely with lavender on the back, a few flowers in the raceme, the fruit is spherical, flat Round or oval, orange-red, the peel is difficult or easy to peel off, the color of the mesocarp is blood red or dark purple, but the immature fruit is not colored, the fruit is full or semi-full, the pulp is orange-red or purple when ripe, Sweet or slightly sour. [0003] The comprehensive traits of Taroko blood orange is one of the better varieties of bl...

Problems solved by technology

[0004] During the planting and management of tarocco blood oranges, it is necessary to meet the management of more water and more fertilizers, so water and fertilization is a very important link in the planting management process; in the traditional planting process, the base fertilizer is applied in the planting hole, and the later fertilization is mostly chemical fertilizer Mainly, this method of fertilization can meet the nutritional needs of plants in the short term, but long-term application of chemical fertilizers will easily lead to soil compaction in the planting site. After the soil in the planting site is compacted, it is not conducive to the absorption of nutrients by the plants; organic fertilizers can solve the problem of soil compaction, but At present, the fertility of organic fertilizers is limited, and the amount of fertilizer applied by organic fertilizer alone is large. The fertilization process requires a lot of manpower and material resources to transport the fertilizer to the planting site; because tarocco blood oranges not only need fertilizer, but also need to meet water, a lot of water is required , if the water is insufficient, it will easily lead to the appearance of dried heart fruit, and the taste will be poor; therefore, it is necessary to provide a fertilization method that is beneficial to the absorption of blood orange plant nutrients and meets the water and fertilizer requirements of the growth process
