Embodiment

[0030] 1. Basic situation of the experimental garden: The experimental garden is located in Baotou Lake Farm, Korla City, Bazhou, Xinjiang, with a total area of ​​50 mu. The fragrant pear garden is neat and tidy. The age of the trees is 25 years. The distance between plants and rows is 4.0 meters x 6.0 meters. The trees are strong and the trees are scattered and layered. The soil texture of the orchard is sandy loam, with good water retention and average soil fertility. The irrigation water quality is 0.84g / L, which belongs to brackish water. The conventional fertilization garden was used as the control.

[0031] 2. Sprinkler irrigation installation: According to the row spacing of fragrant pear plants, the design radius of sprinkler irrigation is 10-11m, the spacing of the outlet risers of the sprinkler irrigation pipe network is designed to be 24m×22m, and the water output of the nozzles is 2.6-3.0m 3 / h, the nozzle is a plastic rocker nozzle, the specification is 1 inch D...

Abstract

The invention discloses a fertilizing method for improving the yield and quality of korla pears. The method comprises the following steps of installing a high-position spraying facility, performing fertilization in a germination stage, performing leaf expansion and flowering period spraying, performing fruitlet expansion and growing period spraying, performing spraying in a fruit expansion period, and performing fertilization in a fruit mature harvesting period. According to the method, furrow application topdressing is converted into high-position spraying, on the basis of the korla pear growth rhythm, a large amount of medium trace elements are sprayed at the position 30 cm above the crown by means of high-position spraying, and the requirement of plants for nutrients is met. On the basis of repeated, slight, proper and targeted fertilizer application, the phenomenon that plant photosynthesis and respiration intensity are lowered due to plant nutritional efficiency is relieved in time, normal growth of trees is ensured, and the yield and quality of the korla pears are improved.

Description

technical field [0001] The invention belongs to the technical field of economic forest fertilization, and in particular relates to a fertilization method for improving the yield and quality of Korla fragrant pears by utilizing high-level spraying technology. Background technique [0002] Korla fragrant pear (Pyrus sinkiangensis Yu) is an excellent variety with strong regional characteristics. It has been cultivated for 1400-2000 years. It is distributed in the Tarim Basin around Xinjiang, and the Korla area is the most concentrated. The fruit of Korla fragrant pear is moderate in size, rich in fragrance, thin in skin and crisp in flesh, sweet and refreshing, tender and juicy, rich in vitamins and resistant to storage, especially the most unique aroma. It has been exported to Europe, America, Southeast Asia and other regions, becoming an important local economic Source of income. Since 2007, Korla fragrant pear has become the primary income industry for local farmers, with a...
