How to grow cinnabar orange

1. Maintain the main branches and backbone branches

The first step is to raise the main branches and backbone branches. After successful grafting, pruning should begin after the buds of the graft or scion sprout and grow. Because the buds of citrus are compound buds, if more than 2 shoots are germinated on the buds or manuscripts, only one tip at the top should be retained as the trunk of culture, and the rest should be erased from the base. When the remaining branches grow to maturity, cut off the upper part of the branches, leaving only about 10 cm as the trunk, which is called a fixed stem, allowing it to sprout and produce lateral branches. After setting the stem, a number of lateral branches will germinate on the hand trunk, which will be used as backbone branches and then pruned, leaving more than 5 or 6 nodes at the base of each branch to regenerate secondary lateral branches, which will be pruned in this way after maturity, trimming 3 or 4 times a year (according to the number of shoots) so that the plant can form a good crown. After each pruning, if you find that each branch sends out too many and too dense shoots, it is also necessary to erase some of the overdense and weak shoots. If unsuitable branches are found on the plant, they should be cut off at any time. This is the first step.

2. The last pruning before the result

The last pruning before the result is very important, because the last pruning time before the result is different for different varieties, and the pruning time for different producers is not the same in Guangdong. For example, cinnabar tangerine, the last pruning time is from July to August 15 of the previous lunar calendar; for tangerine, the last pruning time is in April of the lunar calendar, and water production and flower promotion work is carried out 45-60 days later; for kumquat, the last pruning time is in the fifth month of the lunar calendar, and then water production and flower promotion work is carried out during the period of Greater Heat. Ensure the planting effect.

3. Pick flowers and wipe shoots

Do you understand the process of picking flowers and wiping them off? Some tangerine plants grafted on the pot at the beginning of the year can blossom and bear fruit naturally that year. However, at this time, because the plant is still young, few branches, poor plant shape, or less flowering or low fruiting rate, and the natural fruit ripening period is not just around the Spring Festival, the final ornamental value of the plant is not great, so it is generally not allowed to blossom and bear fruit in that year. The next year, let it blossom and bear fruit. In this way, in the first year, in order to reduce the nutritional consumption of the plant and ensure the better growth of branches and leaves, when the plant blossoms naturally, the buds should be picked manually in time to avoid fruit. The plant will blossom and bear fruit many times at the beginning of the second year, that is, the shoot of each period can become the fruiting mother branch or fruiting branch, which will blossom and bear fruit in the same year. If you want it to blossom and bear fruit only in the third year, then every time the branches bloom in the second year, you should pick the buds and flowers manually in time to avoid bearing fruit; and for those with too many branches that are too close, some of the branches that are too dense and too weak should also be erased. If you want it to blossom and bear fruit in the fourth year, then the third year should also be like the second year to pick flowers and wipe shoots. The process is important.

4. Pruning after the result

The pruning after the result is an important step. For different varieties of tangerines, they often continue to blossom and bear fruit after they blossom and bear fruit. If the number of early fruits is enough, the late flowers should be picked manually, otherwise they should continue to blossom and bear fruit, so as to ensure that the whole plant has enough fruit at last. However, if the number of results is really too large, it is necessary to carry out appropriate fruit thinning work. In addition, when the plant bears fruit, there will be new shoots, which are generally allowed to grow and are cut or thinned about 20 days before ornamental or sale, in order to make the branches and fruits of the final ornamental plant dense and uniform. It's the only way to grow well.

Planting techniques and management methods of cinnabar orange

I. planting techniques of cinnabar orange

1. Rootstock breeding

The first is the breeding of rootstocks. The rootstock seedlings of potted cinnabar orange include Fructus Aurantii, medlar rafter, red lemon, four-season orange, sour orange and so on. According to the climatic conditions of our city, we choose Chinese wolfrafters as rootstock seedlings. After grafting, the roots are shallow, the whisker roots are developed, and the hair tips are fast and more. The rootstock seedlings were propagated by cutting as follows: from August to September, 1-2-year-old branches with sufficient nutrient accumulation were selected, the branches with 4-5 buds of 15~20cm were cut, the distance between the two ends of the cuttings was about 1cm, and the lower part of the cuttings was cut into a longer slope, the leaves at the lower end of the cuttings were removed, leaving 2 leaves on them, and 1 leaf was cut off from each leaf, and the root powder was soaked at the base of the cuttings. According to the row spacing of 3~5cm × 10cm plant, it was inserted on the sand bed with the depth of cutting length 2 beat 3. Pay attention to spraying water on the leaf surface and sand bed to keep the air and soil moist and promote root cultivation. After the first new shoot of the ground is ripe, you can divide the bed to the field, cultivate robust rootstock seedlings, and try it.

2. Grafting and raising seedlings

The method of grafting and raising seedlings is to cut small buds. The grafting effect is the best for a period of time from Greater Cold to the Beginning of Spring. One week before grafting, the stock was cut and properly watered to make the sap flow more vigorously, in order to improve the survival rate of grafting, no fertilizer and water was applied after half a month, and then fertilized once every 10 days or so, combined with extra-root topdressing. The "foot buds" sprouting on the rootstock should be erased in time, and the first shoot should be pruned in combination with shaping, and can be unbound to promote the growth of secondary branches in order to cultivate a good crown. It's an important way.

3. Select seedlings and put them on the pot

The selection of seedlings on the pot is the key link. After the new shoots of grafted seedlings are mature, in cool weather (except low temperature and frost weather in winter), the seedlings with round crown, thick branches and green leaves and well-developed roots are selected on the pot, and the pot size is selected according to the seedling size and plant growth strength, the small seedlings are washed with 2.5kg and sterilized tile pots are used for strong seedlings or seedlings with 3.5kg for more than half a year. When putting on the basin, first cover the drainage hole of the basin bottom with a small tile to avoid mud leakage and facilitate drainage and aeration. The basin soil uses a medium with strong water permeability, ventilation, fertilizer and water retention, with 30% cinder and 70% pond mud, and the basin soil should be loaded to 7: 8. After planting, the grafting interface should be exposed to the soil surface, which has just covered the original soil surface of the seedling, and drenched through the root water after planting. Combined with the upper basin, the plant is drenched with water for the first time, and after the basin is set up, it is drenched for the second time to make the soil particles absorb enough water. It's crucial.

4. Turn the basin

Do you know? In fact, turning the basin is one of the main cultivation measures, which is generally carried out after the branches are mature in autumn every year, and a number of new roots can still grow before winter, and the soil should be slightly dry before turning the basin to avoid dripping water to avoid breaking the mud roots. When turning the basin, use a stick to top the hole at the bottom of the basin, lift the seedling or buckle it upside down, and then plant the original plant in a larger basin. It's done.

II. Methods of planting and management of cinnabar orange

1. Colonization

Planting, cinnabar tangerine must be planted at a reasonable density, and then the first thing in inter-garden management is to plant citrus plants, that is, to carefully observe whether there is a lack of seedlings in the garden, or where the density is too high, and that is, where there are seedlings that do not survive after planting, we all need to adjust and replenish them in time. When all the plants in the field survive, that is, the planting is successful, the process is not difficult.

2. Fertilization

Fertilization is very important, as cinnabar oranges need to apply heavy fertilizer once a year, that is, after fruit harvest, this conservation fertilizer is similar to the base fertilizer applied in the first year, but the base fertilizer in the first year is to lay the foundation for the growth and fruit of citrus trees, and the follow-up conservation fertilizer is to prepare for high yield in the coming year. Secondly, the growth time of branches and leaves in spring also needs to be fertilized once a year, which can shorten the growth period to the flowering stage, and then fertilize after entering the flowering stage, mainly by spraying, which is beneficial to promoting flowers and protecting fruits and improving the fruit setting rate. Finally, after setting the fruit, you also need to apply a fertilizer, mainly boron fertilizer, of course, you can spray some special chemicals for strong fruit. Fertilization is the key to make oranges grow more rounded and color more evenly.

3. Weeding

Weeding is important, because in order to increase the yield of citrus, we generally need to weed cinnabar orchard at least three times a year. One is to loosen the soil and breathe air to the fruit trees. The second is to reduce the consumption of nutrients to promote the growth of fruit trees. The third is the fertilizer and water storage capacity of Zhengqing soil, and the fourth is the most important, which can prolong the service life of citrus and increase yield. The normal weeding time is divided into these three: the first is the growing season of branches and leaves in spring, the second is before the fruit trees blossom, and the third is after the fruit, do you understand?

4. Pruning

Pruning is essential, and pruning of branches and leaves of cinnabar orange is very necessary, because fruit trees will not be transplanted after planting, because transplanting will affect yield, so the density between orchards can only be effectively controlled by pruning branches and leaves. The growth of cinnabar orange needs enough sunlight, and secondly, if it wants to accumulate sugar, then sunlight exposure is also very necessary. If you are in a relatively cool change, then you will find that cinnabar orange is sour and astringent, and the taste is very bad. Secondly, we will remove the aged branches and leaves, because the aged branches and leaves basically can not bear any cinnabar orange. It is better to let it grow new strong branches to increase yield, which is a very important way.

5. Clear the garden

Do you know? Probably every winter, we need to clean up the cinnabar orange orchard. First of all, we need to clear the fallen leaves, dead branches, weeds and other substances out of the garden, and the second is to carry out comprehensive disinfection and sterilization. In the process of clearing the garden, we should carefully observe each cinnabar orange tree for disease infection, and if it is found, it needs to be excavated or treated with medicine, and sprinkled with corresponding chemicals for control. At the same time, if more pests are found, it is necessary to spray trichlorfon, chlorothalonil or Bordeaux solution, which can effectively increase the yield of cinnabar orange in the coming year. It's also a very important step.

Control of diseases and insect pests of cinnabar orange

It is understood that the main diseases of cinnabar orange are anthracnose, canker, gum disease, resin disease and so on. The control method is to reduce the source of disease and timely select pesticides to control. For the prevention and treatment of canker disease, we should also pay attention to wiping buds and controlling shoots, so as to avoid repeated infection caused by new shoots, and spray medicine to prevent the disease after typhoon rain. Anthracnose and resin disease should also pay attention to strengthen cultivation and management, enhance tree potential and improve disease resistance. The main pests are leaf moths, butterflies, red rust spiders, aphids, leaf rollers, shell insects and so on. The main control method is spraying control, and attention should be paid to wiping out sporadic shoots, interrupting food sources and uniformly releasing shoots in order to protect shoots by spraying. This can effectively control diseases and insect pests.
