深翻改土的材料有哪些?如何确定改土材料的用量?
深翻改土必须结合施用有机质肥料,才能达到应有的效果;深翻改土穴(沟)中下层以秸秆为主,施用石灰和磷肥等肥土;中上层种绿肥,一年种植二季绿肥,既解决改土材料的不足,又节省翻埋绿肥用工量。这些改土材料施入后可提高土壤孔隙度,促进土壤团粒化,形成良好的土壤结构,使水、肥、气、热协调,增强土壤保水保肥能力,有利根系生长和吸收。
改土材料以深翻穴沟来计算施入量,为使每立方米容积土壤的有机质提高1%左右,一般第立方米沟穴施入稻草等秸秆20千克,绿肥50千克,桔饼肥1.5千克,钙、镁、磷肥和石灰各1~1.5千克。成年树柑桔园深翻改土,在施入有机质和石灰等后,埋肥填土到沟深的2/3处,上层再播种一季冬季绿肥,翌年春翻压绿肥填平沟穴,如郁闭应一次性分3~4层填入大量腐熟有机质肥料,然后覆土。

柑橘缺磷的症状
缺磷症状为新、老叶片由暗绿色转变为青铜色,严重缺乏时叶片呈紫红色,叶缘出现半月形的红色坏死斑,并提前脱落。9月份至10月份,柑桔叶片磷含量低于0.07%为缺乏。叶面喷磷酸二氢钾矫治缺磷效果显著;春夏季增施磷肥,树体较易吸收。

柑橘缺钙的症状
缺钙时老叶叶缘褪绿转黄,渐及叶脉间及侧脉,主脉的基部保持绿色。柑桔喷施波尔多液、石硫合剂药剂较多,大田种植的柑桔很少表现缺钙。只是红壤土酸性大,隔2~3年施用石灰一次,调节酸碱度,改良土壤。

柑橘缺锌的症状
柑桔缺锌较为普遍。缺锌叶片主脉与侧脉呈绿色,叶脉间出现浅绿或黄白斑块,严重缺锌时,斑块扩大,叶片明显变小,新梢节间缩短,枝叶呈丛生状。常采取锌、硼混合叶面喷施措施,有明显增产效果。一般4~7月份叶面喷施0.2%硫酸锌3~4次,可有效解决缺锌问题。

柑橘幼龄树如何确定施肥时期?
当年栽植的柑桔树成活后,当春芽萌发长至2~3厘米时,开始施第一次肥,以后每隔10~15天施1次肥,一年施肥7~8次。以施稀薄水肥为主,8月下旬停止施肥,以防抽发晚秋梢。2~3年生柑桔树在春、夏、秋梢生长期4~8月份,每株施壮梢肥2次。11月份和早春各施1次较重的人、畜粪尿、饼肥等作基肥。

柑橘幼龄树如何确定施肥方法?
1年生柑桔树多采取速效肥对水后追肥,追肥方法有树盘浇施,就是将树盘外缘筑一土埂,肥水浇施在树盘内而不外流;或开挖环状沟、对称条沟施肥。追施沟较浅,一般沟深10~15厘米,宽20~30厘米把肥料施入沟中,施肥后拌和均匀,再盖上土。2~3年生树在雨季采取沟或穴施(干施),干旱时期结合抗旱对水施用。

柑橘结果树如何确定施肥量?
据测定生产1000千克柑桔所消耗营养元素为:氮2.06千克,磷0.218千克,钾为2.38千克。因此,柑桔施肥量参考标准:以每年产柑桔1000~1500千克的柑桔园为例,氮、磷、钾施肥量一般为15~20千克、6~8千克、10~15千克。其中芽前肥占15%~20%,稳果肥占5%~10%,壮果促梢肥占40%~50%,采果肥占25%~30%。通过间作绿肥,增施有机肥,提高土壤有机质含量;适量施用石灰;注意氮、磷、钾搭配,重视微量元素肥料补足,尤其是注重锌、硼、钼等元素施用,尽量做到测土配方施肥和叶片分析等,对于柑桔园的丰产、稳产都有十分重要的意义
