花椒树对氮肥的反应特别明显。氮素过多,新梢长势旺,枝干增粗量大,又易萌发徒长枝、根蘖枝,树体繁茂,受光量少,导致花芽分化受阻,果实着色不佳,影响经济收入。花椒树施肥,应以有机肥料为主,并适量加入一些磷肥、钾肥作基肥。施基肥时间,应在根系第三次生长高峰期即9月中下旬为佳,可使树体休眠枝充实度提高,促进花芽分化。还要在生长季节追施有机肥。一般于3月下旬追施一次发芽肥,5月中旬追施一次保果肥和促进花芽分化肥。为增加树体贮存养分,使花芽分化饱满,来春
The response of pepper tree to nitrogen fertilizer is particularly obvious. Too much nitrogen, the growth of new shoots flourishing branches thick, and easy to germinate leggy branches, root tillers, luxuriant trees, less light, leading to flower bud differentiation blocked, fruit coloring poor, affecting economic income. Pepper tree fertilization, organic fertilizer should be based, and the amount of some phosphate, potassium as a base fertilizer. Base fertilizer time, should be the third root growth of the peak period in late September is better, the tree can increase the degree of dormancy branches to promote flower bud differentiation. But also in the growing season chase organic fertilizer. Usually in late March topdressing germination of fertilizer, mid-May top-dressing fertilizer and promote flower buds fertilizer. To increase the storage of nutrients in the tree, the flower bud full, spring
