Soil improvement method for improving quality of navel orange fruits

Abstract

The invention relates to the technical field of planting of navel orange fruit trees, in particular to a soil improvement method for improving the quality of navel orange fruits. The method comprisesthe steps that in a navel orange plantation, navel oranges with planting survival time of two years or above are selected as female parents, before frost falling in winter, a circle of quicklime is sprayed along the outermost circle of the vertical projections of orange fruit tree crowns on the ground, the soil in the circle is shallowly ploughed by 10-12 cm, a trapezoid deep ditch is aslant dug along the quicklime circle to the exterior of the circle, the inclination angle is 135-150 degrees, and green manure is stacked in the ditch for soil improvement of the plantation. By means of a deep ditch improvement technology, the content of organic matter in the soil of the navel orange plantation is effectively increased, the soil activity is improved, the growth requirement of navel oranges is met, robust growth of the navel orange fruit trees is effectively promoted, the quality of the navel orange fruits is effectively improved, and the economic benefit of navel orange farmers is increased.

Description

technical field [0001] The invention relates to the technical field of navel orange fruit tree planting, in particular to a soil improvement method for improving the quality of navel orange fruit. Background technique [0002] Navel orange is a citrus variety cultivated by various countries in the world. It is rich in nutrition and contains various nutrients necessary for the human body. It is an excellent health-care and nutritious green food. Regular consumption can reduce cholesterol, decompose fat, and reduce non-ferrous metals and radioactive elements in the human body. Accumulation, clearing fire and beautifying, anti-cancer and anti-cancer, and prolonging life. Navel oranges are distributed in countries such as the United States, Brazil, Spain, Japan, Australia, Morocco, South Africa, and China; there are varieties such as Newhall, Penna, Penna, Washington, and Kelai. [0003] In 1820, an orange tree in a monastery in Brazil mutated, and there was a small orange at t...

Problems solved by technology

[0006] However, due to the long survival time of navel orange grafted rootstocks, the soil of the planting site is compacted, the organic matter content in the soil is seriously reduced, and the water distribution is uneven. Simple fertilizer and water management alone cannot improve the soil environment after navel orange grafting, and cannot meet the needs of navel oranges. Due to the growth requirements, the growth of navel orange fruit trees is slow and the fruit quality is reduced; especially after 2 years of navel orange fruit trees that survived grafting only by the original fertilizer and water management technology, the soil compaction in the plantation is more serious, and the soil vitality drops sharply
