How much money can you make by growing one mu of sugar oranges? How to plant high yield? How to effectively control diseases and insect pests?

Sugar orange is no stranger to us, its taste is sweet, it is high sweetness in citrus, and the taste is delicate, there is no residue after eating, so it is very favored by consumers in the market. However, due to the limitations of region and climate, its planting area is limited, and in the face of increasing market demand, we can only start from the output, so how much can one mu of sugar tangerine earn? How can it be planted with high yield? How to effectively prevent diseases and insect pests?

First, how much money can you make by growing one mu of sugar tangerines?

The cost of planting sugar oranges per mu is about 2500 yuan, including material costs, labor costs and land costs, of which pesticides and chemical fertilizers account for the largest proportion of material costs, about 1700 yuan. The yield per mu is about 5000 jin. Then the market price of one jin takes the middle value of 4 yuan, and the net profit of one mu is 5000 jin * 4 yuan / jin-2500 yuan = 17500 yuan.

Second, how can sugar tangerine be planted with high yield?

1. Select seedlings

In order to achieve high yield, we must first select pure varieties, disease-free and strong seedlings, in addition, the varieties and yield of early-maturing varieties are better, but also through the grafting technology, through the advantages of varieties. The seedlings with Fructus Aurantii as rootstock have dwarf plant, high fruit and high yield, while those with sour orange as rootstock have tall and erect tree shape and late fruit. Therefore, the seedling grafting interface height is required to reach 0.6 cm, the height should reach 50 cm, it is better to have more than 3 complete branches, the root system is intact, so that high quality varieties can be grafted.

2. Reasonable close planting

Sand sugar orange itself has the characteristics of premature and high yield, so reasonable close planting, planned use of early land, can be through the orchard yield, generally through this method can double the yield. When planting, choose loose, fertile, moist soil environment, planted in 200-300 plants per mu, plant row spacing of about 2 × 1.5 meters. In addition, practical production shows that dwarfing and dense planting is also an important technology to achieve early fruiting and high yield.

3. Management of young tree stage

The stage from planting to flowering is the young tree stage, which usually lasts for 2 years. At this time, what we need to do is to strengthen tree nutrition, cultivate crown and root system, and reasonable pruning. Pruning should be carried out after planting, and 5-6 short branches should be left on the main branches to strengthen the management of fertilizer and water to promote the germination of new shoots. after the new shoots germinate, 3-4 branches with uniform growth and uniform distribution should be selected as auxiliary main branches. after the new shoots are ripe, they will be cut short again and repeat many times to form a crown. It is the peak growing season of young trees in summer, so in order to bear fruit early, it is necessary to wipe buds to promote shoots, to make the summer shoots grow uniformly, and in the second year, it is mainly reasonable pruning to enlarge the crown, and in addition, the amount of fertilizer applied at the shoot stage is more than twice that of the first year. to promote the formation of the crown as soon as possible.

4. Management of the result period

After the management of the young tree stage, the canopy of sugar orange has basically taken shape, beginning to bear fruit in the third year, and the full fruit period is in the fifth year. The most important measure in this period is to protect flowers and fruits. Sand sugar orange has a large number of flowers, but it is easy to fall flowers, so it is necessary to spray foliar fertilizer in time to protect flowers. foliar fertilizer is mainly sprayed with dissolved oxygen made of borax or potassium dihydrogen phosphate mixed with water. In addition to falling flowers, Shatang tangerine has two natural physiological fruit drops, especially the second physiological fruit drop is larger, when gibberellic acid is sprayed in the whole orchard to protect fruit, when the physiological fruit drop is still serious, ring cutting can be carried out to promote flower bud differentiation and improve fruit quality.

When will the sugar orange ripen?

The ripening period of sugar orange is generally from late October to mid-November. Sugar orange, also known as sugar orange, sugar orange, known as "October orange", florescence is generally in late March, late September gradually sweetened, mature harvest period is from late October to mid-November.

Fourth, how to effectively control sugar orange diseases and insect pests?

1. Seize the best time for prevention and control.

Spraying control of ① shoots when sprouting 1-2 cm; control of diseases and insect pests before high incidence period; control after continuous rainfall.

② winter cleaning is a good time to get rid of orchard diseases and insect pests.

Acetylene mites + chlorpyrifos + mancozeb + foliar fertilizer

Mineral oil + chlorpyrifos + prochloraz + foliar fertilizer

Acetamiprid + avermectin + mancozeb.

2. Correct use of medicament

When ① uses the same insecticide for a long time, the drug resistance of some diseases and pests increases significantly. In order to avoid the occurrence of drug resistance of diseases and insect pests, it is recommended to rotate the use of pesticides.

② when a disease and insect outbreak, the use of therapeutic agents, it is recommended to spray alone, do not add foliar spray together.

3. Spray should be in place

It is recommended to use high-pressure sprayer, leaf surface, leaf back, inner hall and so on all should be sprayed in place, can not leave a dead corner.

4. Clean up in time

Remove uncontrollable diseased trees in time and burn them centrally to prevent infection.
