(一)科学施肥。柑桔采果后、应及时追施采果肥。因为柑桔通过一年的开花结果和生长,树体的营养消耗多,要及时施肥补充,以尽快恢复树势,减少冬季落叶,增加花芽分化。施肥应以有机肥为主,配施少量氮素化肥,一般成年桔树每株施土杂肥50—100千克,同时施尿素0.3千克。 (二)注意灌水。冬季干旱是引起不正常落叶的重要原因。由于柑桔果实采收后,树体水分养分损耗大,冬季雨水少,如果过度干旱,就会使叶片出现卷曲现象甚至萎蔫脱落。因此,如
(A) scientific fertilization. Citrus picking fruit, should be topdressing plucked fruit. Because the citrus fruit through a year of flowering and growth, the body’s nutrition and more consumption, timely fertilization to restore the tree vigor as soon as possible to reduce winter deciduous, increased flower bud differentiation. Fertilization should be based on organic fertilizer, with a small amount of nitrogen fertilizer, general adult orange tree soil fertilizers 50-100 kg per plant, while urea 0.3 kg. (B) pay attention to irrigation. Winter drought is an important cause of abnormal deciduous leaves. As the harvest of citrus fruits, tree water loss of large nutrients, less rain in winter, if excessive drought, it will make the leaves curl phenomenon or even wilting off. So, for example
