The latest course on planting techniques and methods of sugar tangerine
Sugar orange, also known as October orange, is an evergreen plant belonging to citrus of Rutaceae. it originated in Yunan County, Huaiji, Guangning, Sihui and Xinyi City. it was originally produced in Shatang Village, Huangtian Town, Sihui City, hence its name. Now Lipu County, Guilin City, Guangxi is now the county with the largest area of growing sugar orange in the country. Let's take a look at the planting technology of sand sugar orange.
Growth habit
The growth and development, flowering and fruiting of citrus trees are closely related to the environmental conditions such as temperature, sunshine, moisture (humidity), soil, wind, altitude, topography and slope direction, which affect the temperature of the most. Even if the air temperature difference of 0.5 ℃ sometimes has different results, high temperature is not conducive to the growth and development of citrus, and the fruit and root system stop growing when the air temperature and soil temperature are higher than 37 ℃. Citrus is a shade-tolerant tree species, but good sunshine is still needed for high quality and high yield. generally, areas with sunshine hours of 1200 to 2200 hours a year can grow normally. Citrus can adapt to a wide range of soil, purple soil, red-yellow soil, beach and coastal land, the pH value of 4.5-8 can grow, and the pH value of 5.5-6.5 is the most suitable.
Dig planting pit
The length × width × depth of sand sugar orange planting pit is 0.5 × 0.5 × 0.5 m respectively. When digging the pit, the topsoil is stacked separately from the heart. When returning to the pit, 10 jin of miscellaneous fertilizer, 5 jin of weeds, 1 jin of phosphate fertilizer and 0.5 jin of lime are placed in each pit. When returning to the pit, the soil fertilizer, phosphate fertilizer, lime and topsoil are mixed with weeds in layers to return to the pit, and the returned soil is 30 cm higher than the pit surface and made into a fruit plate. The planting specification is 2.5 × 3 meters, and 80 plants are planted per mu.
Seedling planting
The planting depth of sugar orange should be in the original position of flat seedling wood, the root should be paddled first, and the root system should be naturally expanded and compacted, and after planting, it should be drenched with fixed root water and covered with weeds 10 cm thick or covered with plastic film to keep warm and moisture. it must be drenched every night for the first three days, and then drenched every other day, depending on the weather or 7 days or 10 days and a half months after a week, until the rainy season.
Soil management
The cultivation of sugar tangerine should do a good job in deeply expanding holes and ripening the soil, forbidding the planting of tall plants such as corn and wheat in the garden, and doing a good job in rational intercropping and weeding in orchards. The soil layer is required to be deep (60 cm) and fertile. The ph value of soil is 5.5-7.0. The slope of the orchard is less than 25 degrees. When planning the garden, there shall be necessary roads, drainage and irrigation, water storage and ancillary construction facilities. In specific planning, we should concentrate as much as possible and build gardens in places with good transportation and water sources.
