Abstract:
The early ripening variety ‘Zhongli No.1’ and the medium ripening variety ‘Wonhwang’ pear tree materials of Henan Province were used as experiment materials.During the two growth cycles of 2017—2018 and 2018—2019,three fertilization levels of conventional fertilization (T0),single-fold drip irrigation (D1) and double drip irrigation (D2) were conducted to study the effects of different application amounts of fertilizer on fruit nutrients,yield and quality,in order to provide a reference for the promotion of water and fertilizer integrated technology in pear production.The results showed that the mineral nutrient contents of ‘Zhongli No.1’ and ‘Wonhwang’ pear fruits under different fertilization treatments had the same trend with the growth stage,and were all at a high value at the young fruit stage,and there was no significant difference between treatments.The yield of ‘Zhongli No.1’ under single-fold drip irrigation was higher than that under double drip irrigation,and there was no difference between single-fold drip irrigation and that under double drip irrigation in the average yield of commercial fruit plants.The soluble solid content of fruit under double drip irrigation was increased.The yield of ‘Wonhwang’ under single-fold drip irrigation was no significant difference to that under double drip irrigation and the conventional fertilization,but the soluble solids content was lower than the conventional fertilization and double drip irrigation,showed that less dosage of water soluble fertilizer could guarantee the normal production,but to maintain high fruit quality needed more fertilizer supply.The fertilizer amount and input cost of drip irrigation were significantly lower than that of using fertilizer applicator.In conclusion,drip fertigation management increased yield and fruit quality of different orchards in different ecological regions significantly.It got the purpose of saving water and reducding fertilizer applied amount.And the fruit production should use appropriate fertigation modes according to the actual situation of orchard in order to achieve high yield，high efficiency and high quality.
