1, just keep the soil moist often. If it doesn't rain after planting, you can water it once every 3-4 days instead of showering it every day.

2. When planting in windy places, it is best to fix the seedlings with bamboo to prevent the seedlings from hanging, otherwise it will be unfavorable for growth.

3. Fertilization: Don't fertilize immediately after planting, so as not to damage the roots and waste fertilizer. Generally speaking, plants begin to take root 15 days after planting, and decomposed water and fertilizer can be applied one month later, based on the principle of diligent application and thin application. In the future, master the principle of two fertilizers for one branch: apply fertilizer once when the planted seedlings grow new buds and begin to mature, apply fertilizer for the second time when the new buds begin to sprout, and so on.

Eliminate pests and diseases

Citrus diseases and pests are serious. Practice has proved that more florists and chemicals are used to grow citrus than other fruit trees. If it is not prevented in time, the growth of seedlings will be stagnant, neither dead nor alive.

1. If serious leaf curl is found after planting, some branches and leaves should be cut off in time to improve the survival rate of planting.

2. In early spring, in the middle and late February, that is, before the spring buds germinate, propafenone with the ratio of1000-1500 can be used to kill young mites.

3, leaf miner, red rust spider, scarab, aphid, psyllid, etc. Are the focus of prevention and control work.

Leaf miner

Liriomyza sativae, also known as ghost painting symbol, lays eggs on new shoots. After hatching, larvae dive into leaf epidermis to eat mesophyll, forming a curved tunnel, which makes the damaged leaves roll into a curved shape.

Prevention and control: when the new bud grows to half a grain, it begins to spray poison. Spray medicine every 6-8 days, and each tip is required to spray medicine 2-3 times.

red spider

The individual of Starscream is so small that it is not easy to see with the naked eye. Mainly sucking leaves, tender shoots and juice, and the injured leaves appear dense white spots. In severe cases, the leaves are gray and lose luster, and the leaves and fruits fall off. May to autumn is the peak period, especially in the high temperature and dry season.

aphid

Aphids generally suck the sap from new shoots, which makes them yellow and wither, affecting the growth of plants. In addition, it can also induce other diseases. Pesticides such as dimethoate and dichlorvos can be used for poisoning.

The shaping of young trees

Young trees can put bamboo shoots in spring, summer, autumn, late summer or late autumn 3-4 times a year. The shaping of young trees generally requires the height of the trunk of seedlings to be 30-35cm. After the new shoots grow, 3-4 evenly distributed and robust branches are left as primary branches, and the mid-autumn branches (early branches in September) are left as secondary branches. Because young trees generally have small branch angles and dense and upright branches, which is not conducive to the formation of a high-yield crown, artificial pulling wires can be used for shaping, so that the opening angle of the main branches and trunk should be 45 degrees to 50 degrees. After continuous shaping, a high-yield crown with compact branches and tips can be formed to achieve the goal of high yield.
