桃矮化砧在日本的研究应用近年来,由于人们对桃矮化栽培的重视,因而毛樱桃(P·tomentosa)等的矮化作用引起了人们的注意。现将毛樱桃作桃矮砧的表现介绍如下:①定植初期,毛樱桃砧与共砧没有差异。2年生时新梢生长受到抑制,生长提早一个月停止,且75％着生了花芽(共砧42％)。②毛樱桃砧有促进晚熟种提前成熟、提高糖度的倾向。③毛樱桃砧对土壤 PH 适应性广,但耐涝性较共砧差。④套袋后的生理落果减少,单果重增大。⑤毛樱桃砧吸肥力弱,需要比共砧更多地施肥。⑥定植密度以2×4米为宜。另外尚有郁李(P·Japnica)、寿星桃等正在研究中。
Peach dwarf anvil research and application in Japan In recent years, due to people’s attention to the cultivation of peach dwarf, dwarfing effect such as P. tomentosa attracted people’s attention. Now the performance of the peach dwarf angels for the introduction of the following: ① colonization, cherry anvil and the anvil were no differences. 2-year-old shoot growth was inhibited, growth stopped one month earlier, and 75% of flower buds were born (a total of 42% of anvil). ② hairy cherry angels to promote early maturity maturity, increase the tendency of the sugar content. ③ wool cherry ankle PH wide adaptability to the soil, but the waterlogging than the total anvil poor. ④ After bagging physiological fruit drop reduced, fruit weight increased. ⑤ hairy cherry ankle suction weak, need more than a total of anvil fertilizer. ⑥ planting density to 2 × 4 meters is appropriate. In addition there are still Plum (P · Japnica), lobster peach and other research.
