There are many kinds of fertilizers used as base fertilizers, such as human waste, pig dung, compost, cake fertilizer, green manure, fertilizer mud, bone meal, phosphate rock, leaves, and weeds. Application should be organic and inorganic, rapid and effective combination of delay; under the premise of delayed organic fertilizer, can be mixed with a small amount of fast-acting fertilizer, and appropriate deep. 1-5 years old saplings, each plant should be applied about 15 kilograms of cow dung, cake fat 0.3-0.5 kilograms; 6-10 year-old result tree should be applied to each strain of fermented pig cow manure about 50 kg, about 0.1 kg urea, superphosphate About 0.3-0.5 kilograms of calcium; 10 years of age or more adult tree should be applied to each strain of fermented pig cow manure about 70-100 kilograms, about 0.2 kilograms of urea, superphosphate about 1.0 kilograms.
The basal application period began before and after fruit harvesting until February of the following year. However, it is best to apply early fertilization before harvesting in October because the temperature is higher and the autumn shoots have stopped growing. The wounds after fertilization and root cutting can be compared. Long healing time, and can promote new roots, play a role in root pruning; roots absorb fat faster, can extend the root activity time, promote tree nutrient accumulation, increase cell fluid concentration, restore tree vigor. At the same time, the fertilizer has ample time to decompose and decompose, and it can timely supply the nutritional needs of flower bud differentiation, spring root activity, sprouting shoots, flowering fruit set and young fruit development.
The application methods of basal fertilizer are as follows:
(1) Ring fertilization method: According to the size of the crown, the main groove is used as the center to dig a ring-shaped groove. The depth of the groove is determined by the depth of the root system, generally 20-30 cm deep and 30 cm wide. This method is commonly used when saplings and fertilizers are low.
(2) Radiation fertilization fertilization method: dig 5 radial grooves in the tree tray, the width of the groove is about 30 centimeters, and it should be shallow near the trunk and gradually deepen outward.
(3) Trench fertilization method: Excavate the strip-shaped trenches between the rows of the orange trees and between the plants. The depth and width of the trenches are about 30 centimeters each, and the soil is filled after fertilization. This method is applicable to those that have been sealed. Adult orange garden.
(4) Disc fertilization method: Take the trunk as the center and open the soil to a disc shape. It should be shallow near the trunk and gradually deepen outwards. The mound should be thrown out of the plate and the fertilizer should be evenly thrown into the plate. Then cover the soil and fill it. This method is suitable for saplings.
(5) The whole garden appellation method: spread the fertilizer evenly throughout the garden, and then combine the deep plowing of the late autumn and early winter or early spring to turn the fertilizer into the soil as the base fertilizer. This method is suitable for adult orange gardens where the roots have been covered with the whole garden, but it cannot be used for a long time.
