在承担重庆市科委下达的《黄桃优质丰产栽培技术推广》课题中,针对南方黄桃生产普遍存在的花量大、落花落果严重、单产低、品质差的状况,为探索出提高黄桃座果率,增加产量,改进品质的技术措施。我们将Vb氨基酸稀土、鄂T——2、防落素于1991年进行田间对比试验,现将试验结果整理于后。 In the commitment of Chongqing Municipal Science and Technology Commission issued the “yellow peach quality and high yield cultivation technology promotion,” the topic, the South Peach production ubiquitous large amount of flowers, falling flowers serious, low yield, poor quality conditions, to explore the improvement Peach Fruit rate, increase output, improve the quality of technical measures. We will Vb amino acid rare earth, E T - 2, anti - dropout in 1991 field comparison test, the test results are now sorted out.
