Abstract

The invention provides a method for reducing fruit drop of Xanthoceras sorbifolia Bunge during young fruit period. The method comprises the following steps: applying 40-60ppm naphthyl acetic acid to fertile flowers with dosage of 500-800 L per acre in the full bloom stage of Xanthoceras sorbifolia Bunge tree; and not irrigating the Xanthoceras sorbifolia Bunge tree within 45 days from the sprouting period to the dilating period. By the method, the fruit setting rate of Xanthoceras sorbifolia Bunge can reach 70-90 percent. The method is suitable for Xanthoceras sorbifolia Bunge planting regions with annual rainfall less than 350 millimeters.

Description

technical field [0001] The invention relates to the construction of economic forests, and is especially suitable for the planting of sorbifolium sorbifolium, especially for the fruit drop phenomenon in the young fruit stage, and can effectively improve the yield and quality through scientific treatment. Background technique [0002] In my country's sorbifolium planting area, sorbifolium ( Xanthoceras sorbifolia Bunge.) The fruit drop is very serious in the young fruit stage of the tree, and the fruit setting rate is only 2 to 5% in general. According to statistics, 74% of the young fruits will fall off within 7 days after the flower fades, and the remaining 24% will fall off in 10 days; the phenomenon of one fruit with one thousand flowers is very common, and this is also a technology that restricts the industrialization of sorbifolia bottleneck. [0003] For a long time, most researchers searched for the reasons for the fruit drop of X. sorbifolium in the young fruit per...
