      不同药剂对石榴可育花比率及产量和品质的影响

      Effect of Different Reagents on the Proportion of Fertile Flower and Fruit Yield and Quality in of Pomegranate

      摘要:
      以9年生‘突尼斯,软籽石榴为材料,在不同物候时期,通过叶面喷施、土壤施入的方法,研究了赤霉素、PBO、多效唑、2,4-D、KT-30和硼砂及其组合处理对石榴可育花比例、坐果及产量和果实品质的影响.结果表明,分别在石榴花芽分化初期(7月20日)、休眠期(10月5日)、胚珠分化初期(4月21日)连续3次喷施多效唑100~300倍液,在花芽分化初期(7月20日)于根部土壤施入2~3 g·cm-1的多效唑,均能显著提高石榴的可育花比例;在花蕾期,全株喷施GA310 mg·L-1+2,4-D 10 mg·L 1或1 000 mg·L-1 B或B 300 mg·L-1-+-KH2PO4 300 mg·L-1+尿素500 mg·L-1,能显著促进石榴坐果,提高产量.
      Abstract:
      Taking the plants of 9-year-old pomegranate (cultivar'Tunisa') as materials,the effects of different reagents (GA3,PBO,PP-333,24,-D and KT-30) on the proportion of fertile flower and fruit yield and quality were examined by spraying the reagents on the leaf surface and applying in the soil before flowering and flowering stages.It was found that the rate of fertile flower was significantly promoted after consecutively spraying 100-300 times PP-333 solution at the beginning of the bud differentiation (July 20),dormant (October 5),early ovule differentiation (April 21),or applying 2-3 g · cm-1 PP-333 in the root soil at the beginning of the flower bud differentiation (July 20).The whole of spraying GA3 10 mg · L-1+2,4-D 10 mg · L-1,1 000 mg · L-1 B,B 300 mg · L-1 +KH2PO4 300 mg · L-1 +N 500 mg · L-1 during flowering stage could significantly enhance the yield and quality of pomegranate.
