辣椒施肥的方法

一般的辣椒植株矮小,生长结果时间长,虽不是要大肥大小的,但施肥是增产的重要措施。

1.追肥第一次追肥在植株成活后,亩施1%硫酸铵水溶液约500kg,点根浇。第二次在植株现蕾时,用40%人粪尿约600kg或硫酸钙15kg兑水4%水溶液点根浇。第三次于5月下旬,第一簇果实开始长大。这时需要大量的营养物质来促进枝叶生长,否则不但影响结果而且植株生长也受到抑制。宜用速效性肥料,每亩用50%人粪尿约800kg。点根烧或硫酸铵约10kg,过磷酸钙约5kg,将上述肥料混匀后条施或穴施,后浇水。第四次在6月下旬,天气转热,正是结果旺期,结合送水,用肥量和施肥方法参照第三次追肥。第五次在8月上旬,气温高,辣椒生长缓慢,叶色淡绿,果实小而结果少,每亩施20%人粪尿约800kg或2%硫酸铵水溶液,以促进辣椒秋后枝叶的生长和结果。第六次追肥在9月中旬,施用量和施肥方法参照第五次,保证生长后期的收获。辣椒施肥次数多是保证长时间生长结果和抗恶劣环境的需要,据杭州菜农的施肥经验,在早期开花以前的一段时间里应多施氮肥,促进枝叶的生长,增加开花数和开花数目(每一节开一簇花)。但开花结果的时间会延迟一些。如果要提早采收,则在现蕾以前,少施氮肥多施磷钾肥。等到第一批果实结成之后,才适当增加氮肥。如提早结果,对总产量有影响。

2.基肥辣椒宜用迟效性肥料,每亩用厩肥约600kg、或迟效性磷肥,也可用过磷酸钙约20kg,将上述肥料混匀后,结合整地沟施或穴施,覆土后移苗定植、浇水。
