Planting method capable of promoting precocity and high yield of navel oranges

Abstract

The invention relates to a planting method capable of promoting precocity and high yield of navel oranges. The planting method comprises the steps of variety selection, land selection, shed erection,seeding, intercropping and grass planting, shaping and pruning, water and fertilizer management and disease and insect pest management. According to the planting method, protection facilities and heating facilities such as a greenhouse and the like are utilized, an appropriate cultivation environment is constructed, a rational cultivation technical means is adopted, the maturity stage of navel oranges is advanced to mid-to-late October, the maturity stage of navel oranges is middle October, maturity is advanced by 30-40 d compared with a common planting method, economic benefits are significantly increased, and precocity, high yield, stable yield and good economic benefits are achieved. Moreover, operation is easy, implementation is convenient, the cost is low, the income of a farmer can be improved, and the method is worth application and popularization; the yield of navel oranges is improved, the fruit surface is smooth and delicate, the fruit skin color is bright and beautiful, thepulp is tender and juicy without residues, and the fruit grade is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a planting method for promoting early maturity and high yield of navel oranges. Background technique [0002] Navel orange, Rutaceae, small evergreen trees of Rutaceae, navel orange is rich in nutrients and contains various nutrients necessary for the human body. The pulp of navel orange is tender and crisp, and the juice cells are orange-yellow, arranged neatly. The juice is sweet and sour, with strong flavor and rich Aroma, navel orange contains more than 55% fruit juice, 85% edible rate, more than 14% soluble solid content, up to 16% soluble solid content, 10.5-12% sugar content, 0.8-0.9 acid content %, solid-acid ratio 15-17:1, vitamin C 46.55-64.0mg / 100mL. Navel orange also contains a lot of vitamin C and carotene, which can help inhibit the formation of carcinogens, soften and protect blood vessels, promote blood circulation, help lower cholesterol ...

Problems solved by technology

At present, most of the fruit trees are sprayed with low-toxicity pesticides and fertilizers to remove insects and supplement nutrients. This method can increase income to a certain extent, but navel oranges will have pesticide residues, and often result in low fruit yields due to improper management. The phenomenon of poor quality, or some growers only determine the type of fertilizer based on general planting experience when fertilizing, or use a large amount of chemical fertilizers and pesticides to increase production, resulting in serious damage to the soil, insufficient nutrients and poor taste of navel oranges. Poor, unable to meet the needs of the market

[0007] At present, the early-maturing cultivation of navel oranges adopts the greenhouse + small shed covering method, and the yield and output value have increased to a certain extent compared with open field cultivation. The market period is in the middle and late May. During the rainy season, large losses are often caused
