This is an overview of the list: how to use citrus flowering. Fat
Fertilization: every 20 hours or so, can be applied in a ditch 30-50 cm from the trunk and can be determined according to the size of the tree; one pair to four for each. At the same time, the leaves are fertilized and the trace elements required for trees are replenished in a timely manner. Fertilization results: during citrus expansion in mid-june and late-june, fertilization accounted for about 60 per cent of total fertilizer application throughout the year。
Fertilization during flowering should be based on quick-impact compound fertilizer and an appropriate increase in nitrogen fertilizer. Depending on the size and growth of the tree, the application of composite fertilizer for each plant is approximately 0. 5 to 0 kg, and the appropriate amount of urea for the weaker tree is 0. 2 to 0. 3 kg. The spring is a critical period for citrus growth, and although tree nutrients are derived mainly from accumulation in the previous year, the situation may be different in that year。
During the flowering period of citrus, the fertilizer used is no longer dominated by organic fertilizers and nitrogen fertilizers used in the long-lived period, but is instead converted to composite fertilizers of phosphorus potassium, which can be used appropriately but not in excess of nitrogen fertilizers, and which, depending on the conditions of the plant, are supplemented by trace elements to ensure the quality of the fruit。
Before and after the harvest, in combination with deep tillage, organic fertilizer, the restoration of tree positions and the promotion of flower thawing have a significant impact by opening deep trenches outside the tree canopy and re-energizing the base fertilizer。
The flower fat of citrus generally requires application before or at the beginning of its gestation, dominated by better water soluble fertilizers, so that when the citrus bud blooms, there is sufficient nutritional support for the bud to grow better, for the later buds to grow and for the stable fruit to sit. The citrus gravitation is followed by the application of fertilizers, the choice of which is dominated by balanced compound fertilizer。
Because flowers consume large amounts of nutrients, citrus flowers are prone to nitrogen, boron and zinc shortages. It is therefore necessary to pay attention to the application of fertilizers to supplement the required nutrients. Nitrogen fertilizer is generally applied during flowering periods, with high nitrogen fertilizer of 1-2kg per acre. And when the flower blooms, it swells. At this point, potassium fertilizer such as potassium should be applied. Ring cut can also be used to protect the fruit. It is better to cut when there are a small number of new buds after the flower is lost. Premature affects the greening of springfalls and sit-ins。

The citrus graft technique is sprouts, which are trimmed from 1 cm below the citrus seedling, and then cut a branch of the tree above the sprouts, while the aluminum is cut at 10 cm from the ground, so that the sprouts and the sprouts can be re-established。
In citrus graft, the graft is cut 1 cm below the gravy seed, then cutting the branch above the lumber. The cut should be at a distance of 10 cm from the ground to ensure that the sprouts of the aluminum are closely integrated with the ear. The cut-off method requires the selection of a healthy branch as a log with a length of about 15 centimetres, unless the whole branch of the branch is to be married。
Citrus matrimony techniques *** the bark of trees cut down from 6-8 centimetres above the ground, approximately 3-5 centimetres in length, deep enough to form layers, and then cut off in a vertical direction. Put the beam around 1 cm below the sprout and cut it 45 cm short, and drop it from 1 cm above the sprout. Cut the branches straight, and then put the sprouts into the cuttings on the wood, and wrap them with plastic sheeting。
The citrus heights are *** the acupuncture wood is to be trimmed before we begin the citrus accommodation, usually in parts more than 5 metres, with all its straight branches cut off, with some tilted branches and side branches kept for the marriage, and all the piping strips below 5 metres kept。
In fact, in general, citrus seedlings can be contracted over four seasons, but at different times. It's better to get married in the spring when it's sprouts, and autumn is a good time to get married. There was less precipitation on these two occasions, and the rate of marriage to citrus in the rain was low. The branches prepare the roots to be evaporated within a month before we get married。
Citrus seedlings *** which is: branch connections: first, a branch with buds is cut flat on the side below the bud, slightly damaging the wood section; the back of the lower side of the front is cut to 45° and a knife is slashed above the bud. The amphibians should also be cut to the sides and cut with a knife at the bottom of the slope in order to strip the wood. And then you're going to pick *** in the slice of gill。
Wally's been on fire in recent years, and there's been a great deal of attention to olympics.
1 integrative shearing: better water fertilizers, strong twigs, new year in guinan 5 ~ 6 times and 4 ~ 5 times in the case of cui-bei, if it is not timely and short-term intercepts and is easily monolithic or results in bushy growth。
2. Vegetable seedlings usually begin to produce results from two to four years after planting. Initially, the results may be small, but as the age of the tree grows, the seedlings will enter production in about the fifth year. The economic life of the olympic trees is usually between 20 and 30 years, with maturity concentrated in two to three months per year. It has a strong productive potential and has a long harvest period。
3 vogly is a late-cooked variety of oranges and oranges mixed up, and in recent years there has been a slow burst of fire in our country. Voreum is still relatively viable. Advantages: a strong, fast expansion of the canopy can enter production early, with thick leaves and strong branches, and five or six times a year in areas with enough heat in nanning and zhong left, which seems to be bigger than all citrus。
4. Land parcels are selected for gold oranges, which are to be planted in loose, fertile, windy, sunward plots. These parcels meet the conditions for the growth of oranges. Before planting, flat plots, 30 centimetres of deep tillage, and adequate levels of rotting organic fertilizer and persulphate are applied in preparation for planting. Worm cultivation should take place at a certain distance, better two metres per tree. Cultivation takes place from april to may each year。
How do you grow the citrus
Soil management. The soil grown in citrus should be ventilated and thick, so that the citrus roots can grow better. The planting of citrus on low-lying plots is usually avoided, with regular deep-turning of the plots, which can remove weeds during the process, as well as increasing the permeability of the soil and preventing soil sheeting. Organic fertilisers can also be applied to improved soil during deep runoff, which is a good contribution to citrus growth. Cut the leaves。
Rational selection of the earth, fruit and tree varieties of orchards: citrus growth is directly influenced by citrus soil, fruit and tree varieties, which require reasonable selection of the earth and fruit and tree species of orchards. The generally selected citrus plantations need to ensure fertile soil, clean soil and distance from cities, with abundant sunlight and good weather conditions。
Soil conditions: when growing citrus, organically rich soils are selected. *** cultivated: citrus seedlings are planted in the soil and watered once a year in spring. Water-water management: when the environment is dry, fresh water is poured into the root of citrus. Plumbing fruit: cut off the marmalades that are growing too much and increase the rate of plant sitting。

Temperature requires an average annual temperature of 16-22°c suitable for citrus cultivation, an absolute lower temperature of thorium-9°c, an average temperature of thorium 4°c in january, an annual temperature of more than 5,000°c in thiram 10°c, and an annual sunlight of more than 1,200 hours. The temperature of citrus above 18 °c begins to grow, 23-29 °c is the most growthal, growth below 13 °c or above 37 °c is inhibited, and fall lumbering requires temperatures around 20 °c and 10 °c, respectively。
The whole period of citrus cultivation can be divided into two broad stages: the fruit harvest period runs from early may to the end of november and from early december to the end of april of the second year. The two major phases are divided on a monthly basis, with different cultivation techniques. The following is a brief introduction to the one-year long-term use of citrus medicine and technology in monthly time。
3 of course, in the case of container seedlings, planting can also take place with guarantees such as irrigation water sources and tree cover. When planting citrus seedlings in the autumn (august-october), it must take place after summer and autumn season. At this point in time, attention should also be paid to the high-temperature drought of august-september. In some areas of high-temperature drought and low rainfall in the autumn, planting can be delayed until the second spring。
