I. How do you grow sandy oranges
1. Plantation specifications:
The plant specifications for sandy oranges vary according to the variety of species and vary according to different conditions, such as logs and soil. The soil is less fertile; the soil is more dense. Most plant density is generally 80-110 units per acre:
3 m (line) x 2 m 80-90 acres
3 m (line) x 2 m 100-110 acres
2. Building readiness:
There are three types of sandy orange plantations, hills and water fields. (1) mountains, hills and hills: thick, but thin, and deep-spoiled green fats are key to success. The pit, which is 0. 8-1 m wide and 0. 6 m deep, is to be dug before planting。
It would have been better if the trenches had been dug, with several layers of weeds, soil fat and approximately 0. 3 metres above the ground. The excavations must be completed at least one month before planting, so that the compost in the pit can rot。
(2) water field: the surface of the field is fertile, but the soil is thin, drainage and lowering of the groundwater table is key to the success of the cultivation, which is reduced by at least 0. 5 metres。
The fields are not capable of digging pits, but rather of raising earth mounds, which are about 0. 3 metres high and have a diameter of 0. 6-0. 8 metres, with drainage ditches around the fields to ensure drainage at all times。
3. Plantation time and methods:
(1) cultivation time: the principle is to last grow before fresh sprouts. The year is usually divided into three periods:
Autumn: september-november, after autumn. If water irrigation is the best planting period, then there will be sufficient time to restore growth. In the cold mountains, where the drought is severe and the wind is cold and cold, it is desirable that it be done sooner or later, preferably by mid-october。
Winterseek: in february, before the spring sprouts or before the onset. After the cold, it warms and grows fast and has a high rate of survival. The disadvantage is that there was a difference in the spring。
Chun-shik: old and matured seeds in april-may spring. At this time, the rains are abundant, the climate is mild, the planting of which is easy to live and grow. In the autumn and winter, areas without water irrigation were chosen for the best。
(2) cultivation methods: the planting of seedlings is carried out with the cooperation of two persons, with a small mud covered with a soft pedal. (b) stuffed root water, so that the roots are clinked with the soil, and eventually the soil is grown into a copper plate, so that the water does not spill and a layer of weed is then covered in the earth。
Post-plant management:
In the absence of rainfall, water will be poured daily for three to four days to keep the soil wet, and subsequently once every two to three days, depending on the shortage of water。
One week after the planting, the caves have fallen slightly to support the stationary plant with bamboo branches in order to prevent the wind from shaking the roots and affecting life. If the leaf is found to be severe, some of the leaves may be properly cut to improve the operation。
The second half of the month in which the plant is grown begins to take root, and one month later it can be fertilized with thin fat, 5-6 times the amount of water added to the manure, or urea combined with water into 0. 5 per cent of the fluid, each applying one or two spoons, thereby contributing to early and multiple rooting of the tree. After that, one or two hits per month。
Plants with new roots and leaves that do not return to normal growth should not be fertilized too early to cause loss of fertility and to survive。

Prevention of diseases:
Because oranges are weak against yellow dragons, they are particularly vulnerable to infection and incidence. It's the enemy of sugar orange growing. Main symptoms: in addition to the presence of yellow stalks, the main characteristics of the disease are:
The base and edges of the blades are fertilized, and there is an irregular yellow-coloured patch。
Methods of response:
(1) choosing disease-free and isolated areas for cultivation。
(2) strict control of vectors - citrus lice, treatment of pests during each sprout and spraying of aphids for pest treatment。
(3) the disease tree is excavated in time to eliminate the source。
Ii. Technological management of sugar and orange production
1. Deep soil conversion and expansion of dens
Mountains, hill orchard orchards, soil erosion, soil acidity, low organic content, and root system growth restrictions that make it difficult to expand around them, should be based on soil and water conservation, deep earth conversions within 1 to 3 years of planting, and a good soil environment for root system growth。
(i) digging trenches
Digging is done on the upper or lower side of the ditch at the time of planting, and by digging the ditch at the time of planting, fertilization and earth cover, with a view to changing the soil from year to year。
(ii) cave expansion
The expansion of the dens was also followed by the excavation of the caves outside the original one, with attention to the connection between the new and the old one, as well as the application of fertilizers and dust during planting, which expanded year by year and eventually led to the deep conversion of the entire garden。
For citrus plantations in water fields or low-wetland areas, the high level of groundwater does not make it advisable to undertake deep conversion throughout the park。
2. Cultivation, cultivation and coverage
Cultivated pine soil can keep its surfaces loose and weeds removed. In particular, ploughing lands were carried out in a timely manner before and after the autumn drought. Mountain orchards can be carried out several times a year at depths of 10 to 20 centimetres. Water fields and low-wetland orchards are, however, forbidden to farm pine fields during the rainy season in order to avoid the creation of roots。
The soil is thicker, soil nutrients are improved, roots are prevented and horizontal roots are fostered. Waterfields and low-wetland orchards may be used in conjunction with digging ditches before the onset of the rainy season; mountain orchards shall be used to produce soil before the onset of the dry season。
Because of its shallow distribution of roots and its vulnerability to adverse external conditions, young citrus trees are then covered with straw or weeds to prevent heat, cold and soil washage, while preventing weeds from breeding and increasing soil organicity。
3 and green fat
The use of green fertilizers in the open areas of juvenile citrus gardens not only discourages weed breeding, but also shades and prevents soil washing。
Directly improved soil, green fertilizers or soybean crop plantations, which are pushed deep into the soil, can increase soil organicity, improve soil structure and improve soil fertility protection. The green manure suitable for planting in the open areas of the park is e. G., thorium, purple clouds, beans, beans, etc。

4. Drainage and irrigation
Water supplies are available during the draw and flowering seasons to ensure that the new ones are robust and the flowering results normal. But there is too much rain, the soil accumulates water and the roots rot. Drainage and irrigation of citrus plantations according to citrus requirements。
Water from citrus gardens shall be subject to the principles of spring wetness, summer drains, autumn irrigation and winter control. When the citrus spring blooms, the soil should be kept humid to ensure the development of spring rises and flowers and to reduce the physiological fallout of flowers。
The summer rains are heavy and the soil is generally wet, and attention should be paid to drainage, lowering groundwater levels and preventing soil wash-up. In autumn, the result was a long-term run-off of the mother branch-fall, and the fruit had entered a period of rapid expansion, when high temperatures, strong sunlight, high evaporation and often drought had to be managed to ensure water availability。
From the fall, when vomiting begins, until the fruit is harvested, and in the event of a drought, the water fields are drained at night, so that the roots are not injured. Water is to be controlled during the winter, the soil is to be properly dry and the buds are to be divided and formed。
5. Fertilisation
(i) fertilization of young trees
In order to meet the requirements of rapid, early and productive production, the young branches, which are staged in the development of productive canopy, should be based on the rapid growth of young trees, small growth, low distribution of root systems, weak capacity to absorb and insatiable fertility, and the hard-working application of fertilizers in order to produce new steps。
A normal juvenile tree is released three to four times a year (1 in the spring, summer, autumn, 1 in the summer or late autumn) with quick-impact compound fat or pig-coated fat on each front and once on each. Fertilizers were applied 2-3 times to promote hair and sprawl, from cutting to greening of new leaves, and quick-impact fertilizer to enrich the branches and provide nutrients for the next launch。
This means that young trees should be fertilized 6 to 12 times a year, with the highest levels of fertilization in winter (before the onset of the spring) and fall seasons, with the bulk of the fertilizer being organic。
It is planned to begin the next year with the use of high-quality organic and small-scale fertilizer in the trees of the hanging fruit, 20-30 days before the release, 20-30 days before the release, 20-30 days after the application of high-quality organic and small-scale fertilizer, additional phosphorus, potassium fertilizer during the fall-off replenishment period, and control of fast-acting nitrogen fertilizer in order to promote the maturity and abundance of the autumn and to lay the foundation for the splitting of the buds。
6. Outcome tree fertilization
As a result, the trees are fertilized in spring, summer, autumn and winter。
1. Spring fertilizers are generally applied in two stages. The first one took place 15 days before the spring sprouts in january-march (sweet oranges in mid-january and honey in wenzhou in early february), making the springs strong and flowering normal. The second was to be used in mid-march and later in the year to supplement the nutrients consumed by flowering and to promote greening of springs and normal development of young fruit。
It is important to note, however, that this period is one of the most sensitive to nitrogen, with inadequate nitrogen fattening, prone to fallers, excessive nitrogen fattening and a high volume of late springs or summer seasons, which, in turn, give rise to a large number of fallouts, so it is important to take seriously the application of fertilizing trees and the combination of phosphorus potassium fertilizer。
In the case of trees with primary production, few results and strong trees, if the green leaves are kept strong, the green fruit may either refrain from fertilizing the flowers, or use weak trees to supplement the fat, or combine with insects in the pursuit of extra-root fertilizers (0. 3%-0. 5% urea or 0. 1% ~0. 2% potassium phosphate) at the rate of about 15% - 20% of the annual fertilizer。
2. The summer fertilisation may not be applied, or less so, in order to control the occurrence of the summer fertilisation for trees that have just entered the outcome period. In the case of trees that have entered the fertilization period, due to the scarcity of summer seasons, the fruit should be reduced to prevent nutrient deficiencies and lead to the vomiting of fallows。
Combination fertilisation with hard work is available. Fertilizers should account for about 10 per cent of the total annual application and be dominated by quick-impact fertilizer。
