花生是一种生长周期较短、效益显著的经济作物。但春种花生容易受病虫和杂草的为害,而且影响较大,常常引起减产甚至失收。下面就花生病虫害防治和杂草防除技术介绍如下,以供参考。花生的主要病害有青枯病、立枯病、叶斑病和锈病等;主要的虫害有蚜虫、蓟马等。主要病害防治1.青枯病、立枯病一是选用抗青枯病品种,如粤油256、粤油92、粤油169等;二是采用整地前亩用50公斤碳铵作底肥可有效防治青枯病、立枯病;三是在幼苗期用69%安克锰锌1000倍液、75%百菌清800倍液、20%
Peanut is a kind of cash crop with short growth cycle and significant benefit. However, spring peanuts are susceptible to pests and weeds, and have a greater impact, often resulting in reduced production or even loss of income. The following peanut pest control and weed control techniques are as follows, for reference. The main peanut diseases are bacterial wilt, blight, leaf spot and rust; the main pests are aphids, thrips and the like. The main disease prevention and control 1 bacterial wilt, damping-off disease is the choice of varieties resistant to bacterial wilt, such as Guangdong 256, Guangdong Oil 92, Guangdong Oil 169; the second is before the land preparation using 50 kg of ammonium bicarbonate as a base fertilizer can be effective Control bacterial wilt, blight; third seedling stage with 69% Anker Mn-Zn 1000 times, 75% chlorothalonil 800 times, 20%
