A fertilization technique for cultivating bright red nectarines in greenhouses

Abstract

The invention mainly relates to the technical field of planting and discloses a fertilization technique of greenhouse cultivated red glossy nectarine. The fertilization technique includes the steps of spring fertilizer deep applying, leaf fertilizer spraying, soil topdressing and fruit picking fertilizer spraying. The method is simple and convenient to operate, the fertilization amount is reduced by 26-29% compared with traditional greenhouse cultivation fertilization, the yield is equivalent to that of a traditional fertilization method, the obtained red glossy nectarine is fragrant and crispy in taste, strong in fruity flavor and moderately sweet and sour, the zinc content of fruits is 3.17 mg / 100 g, the selenium content of the fruits is 4.78 micrograms per 100 grams, the quality of the nectarine is obviously improved, and the economic income of farmers is increased by 10.6%. Before the nectarine germinates in spring, deep fertilization ditches are dug, spring fertilizer is deeply applied, the spring fertilizer has rich organic and inorganic nutrients, the nutrients are balanced, the nutritional ingredients can be rapidly and permanently provided, flower bud differentiation of the nectarine can be promoted, and the blooming and fruiting rate can be increased.

Description

technical field [0001] The invention mainly relates to the field of planting technology, in particular to a fertilization technology for growing bright red nectarines in greenhouses. Background technique [0002] Bright red nectarines are rich in fragrance, sweet, crisp and refreshing, rich in nutrition, rich in sugar, organic acids, vitamins, amino acids, carotene and mineral elements, etc., which can improve immunity, diuresis and swelling, lower blood pressure, relieve cough and reduce phlegm, and strengthen the spleen Nourish the kidneys, promote the growth and development of children, improve intelligence, protect the cardiovascular and cerebrovascular of the elderly, beautify and skin care, and delay aging.

Problems solved by technology

[0003] At present, in the planting process of nectarines, in order to increase the output of nectarines, a large amount of chemical fertilizers are applied during the growth period of nectarines. While promoting the growth of nectarines and increasing production, it will also cause soil compaction and nutritional imbalance. In addition, greenhouse cultivation Due to the limitation of environmental conditions, the sweet and sweet flavor of nectarines is reduced and the taste is poor. This is one of the difficulties that limit the cultivation of nectarines in greenhouses. Therefore, an improved fertilization technology for cultivating red and bright nectarines in greenhouses is needed.
