连续2年多点试验表明:脱毒甘薯通过一系列的高产栽培技术措施,可使其667平方米增产800公斤以上,平均增产63.7％,出粉率提高2.9％。其栽培技术如下: 1.实行一次性施肥 小麦播种时,除给小麦施足底肥外,667平方米再给脱毒甘薯增施有机肥2～3立方米、过磷酸钙40公斤、硫酸钾15公斤,同小麦底肥一同施入,小麦底肥足,苗期苗壮,为丰收奠定了基础,而脱毒甘薯利用剩余肥力,壮而不疯长。地下虫害减少,薯块虫眼率下降80％～90％。试验表明,推行一次性施肥法人麦增产15％～30％,甘薯增产25％左右。
More than two years of continuous experiments showed that: virus-free sweet potato through a series of high-yielding cultivation techniques and measures, 667 square meters can increase its production of more than 800 kilograms, an average yield of 63.7%, 2.9% increase in flour yield. The cultivation techniques are as follows: 1. Implementation of one-time fertilization Wheat sowing, in addition to the application of wheat sole fertilizer, 667 square meters and then given to the detoxification of sweet potato organic fertilizer application 2 to 3 cubic meters, 40 kg of superphosphate, potassium sulfate 15 Kg, applied with wheat base fertilizer, wheat base foot enough, seedling Miao Zhuang, laid the foundation for harvest, and the use of residual fertility sweet potato, strong but not soaring. Decrease in underground pests, potato eye drops rate of 80% to 90%. Tests show that the implementation of one-time fertilization wheat yield 15% to 30%, sweet potato yield of about 25%.
