摘要
选取贵州省盘州市为试验地,设置3个施肥处理组进行春施氮肥对刺梨生长和产量影响的试验。施肥1组施用氯化铵,施肥2组施用硝酸铵,施肥3组施用尿素氮,于刺梨的现蕾期调查春梢数和生长量,并统计其植株的花芽数,待刺梨果实成熟后收集果实计算单株产量。试验表明:春季早期施肥效果优于晚期施肥,其中尿素氮的氮肥形态施用对刺梨的生长和增产上效果最佳。
The effects of spring nitrogen fertilizer on the growth and yield of Rosa roxbunghii were studied in three fertilization treatment groups in Panzhou City.The number of spring shoots and growth of Rosa roxbunghii were investigated at the bud stage,and the number of flower buds of the plants were counted.After the fruits of Rosa roxbunghii were mature,the yield per plant was calculated.The results showed that the effect of fertilization in early spring was better than that in late spring,and the application of urea nitrogen had the best effect on growth and yield increase of Rosa roxbunghii.
