Description

一种怀远石榴的无公害施药方法
技术领域
本发明属于农业种植领域，具体涉及一种怀远石榴的无公害施药方法。
背景技术
怀远石榴产于蚌埠怀远县。古人曾赞其“子白莹澈如水晶，果实大如碗，皮黄而透红，粒精赛玉米，明洁如珍珠，肉肥核细，汁多味甘”，“一粒入口，甜如含蜜”。怀远石榴为我国五大名贵石榴品种之一，而怀远玉石籽石榴名列首位，明清时期即被作为贡品送入宫廷。怀远石榴以其独特的品质畅销国内各大中城市，并远销欧亚。
怀远石榴种植广泛，近些年，随着人们对健康的重视，在石榴种植过程中需要防止过度施药对石榴品质造成的负面影响，现在施药时，为了提升杀虫效果，往往使用浓度高、毒性强的药物，但是这种药物往往会产生较严重的毒性残留，营养石榴的品质，而且会增加害虫的抗药性。
发明内容
本发明的目的是提供一种怀远石榴的无公害施药方法，通过在不同时间段进行施药处理，减少药物使用，提升杀虫、增产效果。
本发明通过以下技术方案实习：
一种怀远石榴的无公害施药方法，
在每年阳历11月下旬，在石榴树周围施用生石灰，具体步骤为以石榴树根部为中心，以1m为半径挖深度为30cm的坑作为施肥沟，将生石灰埋入施肥沟，每棵树使用生石灰1-2.5kg；然后对石榴树干及树枝喷施200倍石灰半量式波尔多液；
在每年3月下旬喷施叶枯唑、氧化乐果、除虫菊酯按重量比1:4:2制成的混合农药1500倍液，防止害虫吞食嫩叶，营养石榴生长；
在每年花期，喷施50wt％多菌灵水分散剂32g、20wt％井冈霉素15g、20wt％硼酸30克和水60千克组成的混合液；
在每年石榴果实膨大期，喷施吡效隆18g、赤霉素6g、水杨酸14g、有机硒肥13g、噻呋酰胺4.5g、多菌灵6g、水35kg组成的混合液。
本发明的有益效果：本发明通过在石榴不同生长期使用不同的药物对石榴的病虫害进行预防，针对性强，杀虫效果明显，而且在病虫害还没有扩大前提前预防，药物使用量少，杀虫、抗病效果明显，而且药物经过复配后，使用较低的浓度即可达到杀虫、抗病效果，对石榴树本身没有伤害，由于药物浓度较低，在杀虫后，药物在短期内即可被降解，对环境无污染，也不会造成药物残留，药物成本降低28%左右。
具体实施方式
一种怀远石榴的无公害施药方法，
在每年阳历11月下旬，在石榴树周围施用生石灰，具体步骤为以石榴树根部为中心，以1m为半径挖深度为30cm的坑作为施肥沟，将生石灰埋入施肥沟，每棵树使用生石灰1-2.5kg，1-2年生石榴树施用量1-1.2kg，3-4年生石榴树使用量1.2-2kg，5年生以上石榴树施用量为2.5kg，可以阻断外部害虫向石榴树移动，侵蚀石榴根部，减少后期害虫对石榴根部的损伤；对于然后对石榴树干及树枝喷施200倍石灰半量式波尔多液，杀灭寄生的细菌、虫卵等；
在每年3月下旬喷施叶枯唑、氧化乐果、除虫菊酯按重量比1:4:2制成的混合农药1500倍液，防止害虫吞食嫩叶，营养石榴生长，经过药物复配，只需要极低的浓度即可达到杀虫效果，而且残留的药物由于浓度极低，可以在短期内被降解，无污染，药物成本低；药物施用量为0.5-1.5kg/棵；根据石榴树的大小及树龄进行常规调节。
在每年花期，喷施50wt％多菌灵水分散剂32g、20wt％井冈霉素15g、20wt％硼酸30克和水60千克组成的混合液，既可以起到良好的杀虫抗病效果，又可以具有增产的效果；药物施用量为1-2kg/棵；根据石榴树的大小及树龄进行常规调节。
在每年石榴果实膨大期，喷施吡效隆18g、赤霉素6g、水杨酸14g、有机硒肥13g、噻呋酰胺4.5g、多菌灵6g、水35kg组成的混合液，施用量为可以提高果实成长率，成果率较高，而且果实表面光滑、形状规则，虫蛀果实的比率降低43%，果实含硒量提高4.8%，无药物残留；药物施用量为1-2kg/棵；根据石榴树的大小及树龄进行常规调节。
