近几年来,长把梨单位面积产量不断上升,质量却呈下降趋势,直接影响了经济效益。造成长把梨品质下降的原因是多方面的: 1.授粉树品种的单一性 据调查大多数果农只用一种授粉树。如秋梨作为授粉树,本身皮厚、星点大、果肉粗、石细胞多、核大,这直接影响了长把梨的品质。为此应积极着手改善授粉树品种的组合结构,提倡用红把甜、鼓根、恩梨等作授粉树,同时应注意和
In recent years, the pears per unit area of production continued to rise, the quality has declined, a direct impact on economic efficiency. The reasons for the long drop in pear quality are many: 1. Simplicity of pollination tree species Most pollinators are surveyed using only one pollination tree. Such as autumn pear as a pollination tree, itself thick skin, large stars, thick flesh, stone cells and more, a large nuclear, which directly affects the quality of long pear. To this end should actively work to improve the combination of the structure of the pollination tree species, promoting the use of red sweet, drum root, grace pear and other pollination trees, should be noted and
