1980—1982年在南京丘陵地区以黄肉罐藏晚熟品种‘金丰’为试材,进行滴灌研究.结果表明:不同类型滴头比较,从流水量和堵塞程度,均以管纹优于发丝和滴珠.明确土质粘重的土壤,灌溉的土壤含水量指标为13％.结合桃树生长发育特点分别于5～6月或7～8月旱季采取补充滴灌,使土壤含水量达到15％～20％范围,具有促进果实生长,增加加工合格果比例,增加维生素C含量和糖酸比,同时增加花芽数量,提高单位面积产量.
The experiment of drip irrigation was carried out in the hilly region of Nanjing from 1980 to 1982, using Jinfeng, a late-maturing yellow canned forage, as the experimental material.The results showed that compared with the drip irrigation and plugging, Silk and dribble.It is clear that the soil with soil is sticky and the index of soil water content for irrigation is 13% .Adjusting the drip irrigation with the growth characteristics of peach tree in the dry season of May to June or July to August respectively, the soil water content reaches 15 % ~ 20% range, with the promotion of fruit growth, increase the proportion of processed fruit, increase the content of vitamin C and sugar to acid ratio, while increasing the number of flower buds, increase yield per unit area.
