菜用枸杞的培植及病虫害防治一提到枸杞人们联想到的便是红红的枸杞子,很少有人知道还有一种可食其嫩叶的菜枸杞。菜用枸杞为茄科落叶灌木,株高1m。枝条细长,长弯曲或俯垂,幼枝有棱角,外皮灰色,无毛,通常具短刺,生于叶腋。叶互生或簇生于短枝上,叶片卵形、卵状菱形或卵状披针形,全缘。花常1-4朵簇生于叶腋,花萼钟状;花冠漏斗状,淡紫色,边缘具缘毛,5深裂。浆果卵状或长圆状,红色,种子多数,扁肾脏状、黄色,花期6-9月,果期8-11月。菜用枸杞适应性强,能耐寒、耐旱,但怕渍水。人工栽培以土层深厚、肥沃、排水良好的沙质壤土和中性或微碱性的土壤为好。在栽培中应注意:一、选地整地选用靠近水源的沙质壤土,轻壤土次之。含盐量在0.2%以下为宜。秋季深耕20-30cm,每667m2施厩肥2000-2500kg,肥料充足者可施4000-5000kg,撒匀耕翻入土中,并浇冻水。次春播种前浅耕细耙作畦,宽1m,长不限,整平畦面待栽。二、播种期及播种方法菜用枸杞春夏秋均可播种,北方地区一般春播,3月下旬播种,播前用40℃温水浸种一昼夜,可促进出苗整齐。播种时开浅沟条播,沟深3-5cm,沟距30cm。种子掺沙混匀,撒入沟内,覆土2-3cm,轻踏后浇水,每667m2播种量0.5-0.7kg。天旱时可在畦面上用稻草、麦秸、油菜秸等覆盖,出苗后揭去覆盖物。注意除草松土、治虫。三、扦插或分蘖苗定植春季解冻后,将耕好、施足基肥的土地作成30cm宽的高垄,高度为20cm,垄距20cm,将插条或分蘖苗按10-15cm株距定植。定植后在垄沟内浇水,以湿透高垄为宜。注意中耕松土,促进生根。四、田间管理菜用枸杞播种或定植后应注意中耕除草,扦插或分蘖苗发根后,每月追施1-2次肥料,适当浇水,保持土壤湿润。在播后50-60d,苗高50cm左右时即可采收。从5月份开始陆续采收,采收时将嫩稍剪下,留下2-3条嫩枝,以备继续生长发育。嫩稍包装后即可上市出售。五、病虫害防治1.菜用枸杞瘿螨。主要为害菜用枸杞叶片、嫩梢及花蕾。被害叶片上密生黄色近圆形隆起的小疱斑,严重时呈淡紫色或黑病状虫瘿,植株生长严重受阻造成果实产量和品质下降。防治方法:(1)在成螨越冬前及越冬后出瘿成螨大量出现时喷药防治,以降低害螨密度。可选用50%杀螨丹胶悬剂600倍液、50%硫磺悬浮剂300倍液或1.8%爱比菌素3000-4000倍液等药剂。(2)掌握当地出瘿成螨外露期或出蜇成螨活动期,喷洒O.5波美度石硫合剂、4%杀螨威乳油2000倍液或50%硫磺悬浮剂300倍液2-3次。2.菜用枸杞负泥虫。主要为害菜用枸杞的嫩叶及嫩梢。成虫和幼虫取食叶片,造成不规则的缺刻和孔洞,严重时吃光全叶,并在枝条上排泄喷便,严重影响了菜用枸杞的产品质量。防治方法:(1)春季越冬幼虫和成虫复苏活动时,结合田间管理灌溉、松土,破坏其越冬环境,以消灭越冬虫口。(2)4月中旬越冬待成虫开始活动时期,可用50%辛硫磷乳油每公顷4000mL加适量的水拌入土中,撒入田内,然后中耕。(3)在幼苗和成虫为害期用90%敌百虫晶体l000倍液、20%速灭杀丁3000倍液或20%杀灭菊酯3000倍液等喷雾,视虫情共喷3-5次,间隔10d左右。3.菜用枸杞蚜。成蚜或若蚜多聚集在嫩叶、嫩芽上刺吸汁液,致使嫩梢呈褐色枯萎状。发生严重时叶片覆盖油渍状分泌物,称为“油汗”,影响光合作用,使叶片早落,树势衰弱。防治方法:(1)秋冬季修剪下的枝条集中烧掉,以消灭越冬卵;生长季及时剪除徒长枝带出,以消灭群集于幼嫩部位的蚜虫,降低田间虫口密度。(2)为害初期及时喷药防治,可选用20%杀灭菊酯2000倍液、50%灭蚜净3000倍液、10%吡虫啉可湿性粉剂1500倍液。六、采收当菜用枸杞主茎高20cm时,即可采嫩尖食用,嫩尖采食后。温暖季节,每15-20d采收1次,冷凉季节30-40天采收1次。
