Nutrition scheme suitable for water planting of fruit-bearing trees of navel oranges

Abstract

The invention discloses a nutrition scheme suitable for water planting of fruit-bearing trees of navel oranges. The nutrition scheme suitable for water planting of the fruit-bearing trees of navel oranges is characterized in that according to the growing characteristics of stages of the fruit-bearing trees of navel oranges, accurate fertilizer formulas, an accurate fertilizer concentration, and afertilization frequency scheme are given, the fertilizer formula of a vegetative growth period is 20-10-20, the fertilizer formula of a blooming and fruit setting period is 20-10-20, the fertilizer formula of a fruit swelling period is 17-4-17-4Ca-1Mg, the fertilizer formula of a fruit color turning period is 13-4-20-4Ca-3Mg, the fertilizer formula after fruit picking is 20-10-20, the fertilizer concentration, namely an EC value, is 1.0-1.5, and according to the fertilization frequency, a fertilizer is added or replaced every 30-45 days. The water-soluble fertilizer used in the nutrition scheme is a total nutrient fertilizer, is in an ionic state, is not subjected to precipitation reactions, and does not cause ion antagonism. Moreover, operation is simple and convenient, and nutrients canbe added according to the growing stages of navel oranges so that the yield and the quality of the fruits can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of citrus cultivation, in particular to a nutritional scheme suitable for hydroponics of navel orange fruit trees. Background technique [0002] Navel orange is Rutaceae, a kind of cultivar of sweet orange in the genus Citrus. The earliest variety of navel orange, Washington navel orange, was transformed from a branch of Brazil's seeded sweet orange in 1870. At the beginning of the 20th century, navel orange was introduced several times. Cultivation was introduced into China. Navel orange is an arbor, with a flowering period of March-May, a fruit period of October-December, and a late-maturing variety until February-April of the following year. The suitable annual rainfall for navel orange planting is about 1600mm, the annual average temperature is 18-22°C, the absolute minimum temperature is not lower than -5°C, the average temperature in January is not lower than 7°C, and the annual average effective accu...
