Planting techniques and Management methods of Sugar Citrus

Sugar orange is very rich in nutrients, especially the content of vitamin C is relatively high, often eat beauty light spot effect, many people also like to use to squeeze orange juice to drink. Sugar tangerines are also very versatile. Canned oranges we often eat are usually made of sugar oranges.

Planting techniques and Management methods of Sugar Citrus

Planting techniques: sugar tangerines are generally planted from February to March in spring. Sand sugar oranges are developed on fertile paddy fields and riverside alluvial soil. Shallow holes can be dug for planting, while paddy fields should be arranged in high beds according to plant rows. For dry land and sloping land with poor soil quality, it is necessary to dig a deep pit of 1 meter square and prepare sufficient base fertilizer. Each pit applies 3 jin of phosphate fertilizer, 5 jin of lime, 100 jin of garbage or pond mud, and 30 jin of pig, cow and chicken manure. When filling the pit, mix the fertilizer with the soil and then fill it back into the pit. The tree plate is about 20 cm higher than the ground. Before planting, cut off some branches and leaves of the seedlings to reduce water evaporation, cut off the main root and retain the fibrous root as much as possible. When planting, dig a shallow hole to let the fibrous root stretch naturally, and then return to the soil to compact the soil. The height of the buried soil can not be buried beyond the joint of the graft. After planting, cover the tree plate with straw or other weeds and sprinkle it with rooting water. Within a month of planting, it is necessary to keep the soil near the root system moist, high temperature, sunny for a long time, dry soil, drenched with water every day, rainy days, when the soil is moist, there is no need to drench water.

Post-planting management: if there is no rain after planting, water should be drenched every day for 3-4 days to keep the soil moist. Depending on the lack of water in the plant, it should be drenched every 2-3 days until it survives. One week after planting, the cave soil has sunk slightly and bamboo branches can be inserted to support the fixed plants to prevent the wind from shaking the roots and affecting the survival. If the rolled leaves are found to be serious after planting, some branches and leaves can be cut off properly to improve the survival rate. Generally, half a month after planting, some plants begin to root, and a month later, thin fertilizer can be applied, 5-6 times with mature human urine, or 0.5% water solution with urea and water, with 1-2 spoonfuls per plant to promote early rooting and multiple roots of young trees. From then on, it will be drenched 1-2 times a month. Plants without new roots and leaves not returning to normal growth should not be fertilized prematurely so as not to cause fertilizer damage and affect survival.

Insect pest treatment of sand sugar orange

1. Scale. The key period of drug control: the sagittal tip scale is the first generation nymph stage, the red wax scale is the larval stage, and the cotton blowing scale is the larval stage. Commonly used agents such as thiazinone, methamphetamidophos, matrine + nicotine, Lesbon, oil emulsion and so on. Pay attention to improve the ventilation and light transmission conditions in the park, protect and make use of natural enemies such as Japanese beetle, red ladybug, lacewing, golden aphid wasp, Australian ladybug, red ladybug and so on.

2. Aphids. The damage rate of new shoots is up to 25%, so it should be sprayed immediately. Commonly used agents are chloramidine, dimethoate, butylthiocarb and so on. Attention should be paid to the protection of ladybugs, lacewings, aphid flies, aphid wasps, etc., cut off overwintering eggs and reduce the base of pests.

3. Leaf miner. The key period of control is the shoot emergence period in summer and autumn. Timely erase sporadic summer and autumn shoots, combined with fertilizer and water management to make the new shoots of the plant strong and neat. Chemical control: spray the new shoots to 1-2cm, once in 7-10 days, 2-3 times in a row. The commonly used agents are avermectin, shamindan, cyhalothrin and so on.

Fertilizer and Water Management of Sugar Citrus

Young tree management takes fertilizer and water management as the center, promoting root growth, early branch growth and rapid development, and the early formation of tree crown. After 40 days of planting, the new roots began to grow, which could be diluted 3 times with rotten manure water and applied every 10 to 15 days, 5 kilograms per tree. With the growth of young trees, the concentration and dosage of manure water were gradually increased, and urea was properly added to dissolve in fecal water and then drenched. From the second year of planting, we can reduce the number of fertilization, increase the amount of manure and chemical fertilizer each time, and apply 30 jin of manure and 3 taels of urea each time. In September, stop applying nitrogen fertilizer and dung water, apply potassium fertilizer once, and apply potassium chloride half a jin per plant to promote flower bud differentiation. At the same time, attention should be paid to soil moisture management.

Pruning the branches and leaves of sugar orange trees

1. Pruning of young trees. After pruning the extended branches of the main branches, heavy shortening should be carried out, and light pruning of the rest of the branches and leaves should be carried out to achieve the purpose of slowing down the growth.

2. Pruning of adult trees. Mainly according to the tree potential and the amount of flowers to determine the weight of pruning, strong trees should be lightly cut, properly subtract the branches and leaves that are too dense, and when the amount of flowers is too large, they can be cut short, in order to reduce the amount of flowers and increase the effective fruit setting rate.

3. Coring can be carried out before flower bud differentiation. New shoots with exuberant growth can be removed with scissors or fingers to help form flower buds and increase fruit setting.

Planting sugar tangerines should choose places where the soil is fertile, and there should be no stagnant water, otherwise it will cause root rot. The late management of sugar orange is also very important, and the branches should be pruned in time to ensure the quality of the fruit. Sugar orange has a wide range of functions, and orange peel has medicinal value, so planting sugar orange is of great economic value, so it is a good choice.
