Li Yuetang is a fruit farmer in Shangzhai Village, Kongtian Town, Anyuan County, Jiangxi Province. His orchard has high yields, excellent quality, high commodity rates, low costs, and good production efficiency. According to statistics, in 2001 (the fourth year) trial production to 2005 five years, the production of navel orange 837,000 kilograms, the output value of 1.583 million yuan, after deducting the construction fee and the cumulative production cost of 600,000 yuan, the cumulative profit of 983,000 yuan. In 2003, the navel oranges selected by the park participated in the quality assessment of navel oranges in the county and won the “Navel Orange”. In 2004, the highest single tree result was 746, and the yield of the plant reached 400 pounds.

First, the orchard basic situation

Li Yuetang’s orchard was planted in Qingshan Mountain in 1997. In March 1998, the seedlings were transplanted and planted in May of that year after being rejuvenated with nutritious vegetation. In 1999 (the second year of colonization), it was slightly frosted. The cultivar is New Zealand Navel Orange. The planting specifications are 3 meters by 3 meters in row spacing, 74 cultivars in acres, and 1618 plants in the park, with a total area of ​​21.86 mus. After the tree was greatly restricted by space, 32 trees were successively cut in the past two years. There are now 1,586 Newhall navel oranges in the whole park. At present, the garden is neat, the tree grows moderately, the tree canopy is tall, the curtains are thick, and the leaves are dark green, and the anniversary does not fade.

Second, the main production experience

1. The application of inorganic fertilizer is mainly based on organic fertilizer. After the application of organic fertilizer in the ditch, water fertilizer (such as paulownia water and manure water) was timely applied, and fertilizer was applied 4 times a year. Taking 2004 as an example, the amount of fertilizer applied per plant was: 1.5 kg of urea, 4 kg of ternary compound fertilizer, 3 kg of calcium magnesium phosphate fertilizer, 22 kg of bio-organic fertilizer, 80 kg of pig manure, and 80 kg of water and fertilizer of Tung fruit cake, respectively, at the beginning of March. (Fertilizer before bud), late May (fixed fruit fertilizer), mid July (attacking autumn shoot strong fruit fertilizer), and late November (overwintering fertilizer). The fertilization method is: Each application of organic fertilizer, open two relative stripe grooves on the outer edge of the canopy drip line, with a groove depth of 30 cm, a width of 10 cm, and a length of 1 meter (applying the chemical fertilizer to open the shallower trenches). , Timely cover soil protection. Fertilization positions rotate one by one. The organic fertilizer, calcium magnesium phosphate fertilizer was applied in two batches in March and July. Urea and compound fertilizer were applied in four equal portions.

2. Change cultivating and weeding for grass cover. The garden is covered with raw (cut) grass and cultivated pest natural enemies (beneficial insects), creating a good environment for habitat predation and reproduction of natural enemies, and exerting anti-drought effects. The gardens are hand mown once a year in early July and mid-October, respectively.

3, change the hormone and preserve fruit as nutrient solution. The use of high-quality nutrient solution to protect the fruit avoids obvious years and years, making the results of each year moderate, and the results are large and flawless. Spraying the brassinolide 6000 times per year during the flowering period, spraying 1500 times the amino acid and 2,000 times the humic acid, respectively, in the young fruit period and the fruit expansion period. Practice has proved that high-quality organic nutrient solution can not only prevent the size of the year, but also make the annual results moderate, the fruit is large and flawless, and achieve the goal of high yield and stable production year after year.

4, to change simple chemicals to prevent pests and diseases for the comprehensive treatment of pests and diseases. To reduce the number of spraying, save the cost of pesticides, and take comprehensive management of pests and diseases. The park organically combines the following technologies and achieved remarkable results: (1) The orchard grows grass and cuts the grass cover, protects the natural enemies of pests, creates a micro-ecological environment, and uses natural enemies to “treat insects with insects and cultivate gardens. "Objective; (2) Cut off pests and leaves, reduce the source of pests and diseases, enhance ventilation and light transmission, and reduce pest damage; (3) Install electronic insect killer lamps in orchards, use pests to light, wave, color, taste The characteristics of trapping and killing beetles, burdockworms, fruit sucking tobacco moths, Spodoptera litura and other pests, reducing the number of spraying and reducing production costs. (4) In the peak season of pests and diseases, priority should be given to the use of highly efficient and low-toxic biological and mineral-sourced pesticides for control.

5, change the fine trim to big branch trim. In order to avoid foot rot and achieve high yield, stable production, and high quality goals, the young trees should be fixed at a high position, and the main stem should be 30 cm. When trimming, the saplings should be moved and cut to remove the buds, sparse, and pick the heart. The main culture of the tree, after the adult closure of the informal section, the implementation of large branches pruning, reduce labor input, saving production costs, year after year to update branches, maintaining high yield, stable production, high quality canopy structure.
