Abstract:
Taking ‘Xinli 7’ and ‘Yali’ as test materials,plant growth regulators,traditional agronomic measures and other treatment methods were used to delay the flowering period of pears,and the anti-low temperature test in early spring was carried out by covering with black PE plastic film and drip irrigation.The delay effects of plant growth regulators and traditional agronomic measures on the flowering period of pear were studied,the effects of covering black PE mulch and drip irrigation on preventing low temperature in early spring were evaluated,in order to provide reference for the regulation of pear flowering period and an environmentally friendly and easy-to-operate anti-low temperature technology.The results showed that,according to the observation of the phenology of ‘Xinli 7’ and ‘Yali’ after different treatments,250 mg?L-1NAA+300 mg?L-1 SA was the best one.The optimal treatment of ‘Xinli 7’ and ‘Yali’ delayed the initial flowering period by 2.0 days and 3.7 days respectively,and there was no significant difference between the fruit setting rate and the control ‘Xinli 7’.The temperature of the 10 cm and 20 cm soil layers from the ground reduced by 0.2-0.6 ℃.The temperature of the soil layer 10 cm and 20 cm away from the ground increased by 0.1 ℃ to 0.3 ℃ when covered with black PE film.On March 19th and 26th,2022,the lowest temperature occurred between 05:00 and 06:00,and the temperature at 1.5 m above the ground covered with black PE film increased by 0.5 ℃ and 1.6 ℃,and at 2.5 m above the ground increased by 0.1 ℃ and 0.8 ℃.After drip irrigation,the temperature at 1.5 m of the canopy increased by 0.3 ℃ and 1 ℃,and at 2.5 m increased by 0.1 ℃ and 0 ℃.By comparison,the effect of covering black PE mulch on the crown growth of ‘Xinli 7’ and ‘Yali’ is better.
