人工栽培半夏[Pinellia ternata(Tnunb.)Breit]常用块茎繁殖。春播的适宜期在三月上旬,而种源经过较长时间的沙藏(一般五个月左右)后,播前进行块茎处理对提高半夏产量的作用如何?用什么药剂进行处理最为有效,目前资料甚少,故进行该项试验研究。1 材料与方法1.1 药剂种类1.1.1 浸种用(1)50%多菌灵、(2)40%乙磷铝、(3)1%生石灰水;1.1.2 土壤消毒用熟石灰。1.2 试验处理方法1.2.1 药剂使用方法1.2.1.1 用一份50%多菌灵加一份40%乙磷铝300倍液;1.2.1.2 50%多菌灵300倍液;
Artificial tubers Pinellia ternata (Tnunb.) Breit commonly reproduce tubers. The suitable period for spring sowing is in early March. After the sand source (usually about five months) has passed for a long time, the effect of tuber processing before sowing on the yield of Pinellia ternate is the most effective. At present, there are few data, so this pilot study was conducted. 1 Materials and methods 1.1 Types of pharmaceuticals 1.1.1 For soaking (1) 50% carbendazim, (2) 40% aluminum alfa, (3) 1% quicklime water; 1.1.2 slaked lime for soil disinfection. 1.2 Test treatment methods 1.2.1 The use of agents 1.2.1.1 Use a 50% carbendazim plus a 40% 300% solution of aluminum alfa; 1.2.1.2 50% carbendazim 300 times;
