摘要
山杏是我国北方半干旱地区特有的重要木本油料树种,但目前仍存在产量不高的问题,严重影响了山杏的产业化发展。通过研究5种药剂喷施后对山杏林生长及物候的影响,采取推迟花期以避冻害提高其成花率和坐果率,采取阻止果实脱落等措施以提高产量,为今后推广及更有效地提高山杏产量提供了科学依据。
Prunus armeriaca is an important and specific woody oil tree species in semi-arid districts in northern China,but its yield is low,which seriously influence its industrialization development.Through studying the influence on the growth and phenology of Prunus armeriaca natural forest after spraying five kinds of chemicals,delaying anthesis is adopted to avoid freeze injury to increase the flower formation rate and fruit setting rate,and the measures of preventing fruit drop to increase the yield,which can provide the scientific basis for effectively increase the yield of Prunus armeriaca in the future.
