甘薯是我国五大种植作物之一。甘薯高产与育苗、适时栽植有关。传统的温炕覆土育苗法,因受多种因素制约,很难达到适时一次栽植。为此,河南浚县农业局农艺师王玉明,经过几年努力和试验,研究出一套甘薯无土育苗和薯苗借植新技术,并已通过技术鉴定。此项技术的做法是,在早春于背风向阳处,建造一个不透水的育苗池(池的大小根据需苗量而定)。然后将消毒灭过菌的薯种尾部朝下放入池内,并用水和多种无机营养素配成营养液后倒入育苗池中,液深以淹没薯种1/3处为宜,采用此法不仅具有养分全、水分足、不加温、无病感染、管 Sweet potato is one of the five crops grown in China. Sweet potato high yield and nursery, timely planting related. Traditional warm Kangding soil nursery method, due to a variety of factors, it is difficult to achieve timely planting. To this end, Henan Junxian Bureau of Agriculture agronomist Wang Yuming, after several years of hard work and testing, developed a set of sweet potato soilless seedlings and seedlings by planting new technology, and has passed the technical appraisal. The technique of this technique is to build a watertight nursery pond in early spring on the leeward side (the size of the pond depends on the amount of seedlings needed). Then sterilize and sterilize the tuber tail down into the pool, and use water and a variety of inorganic nutrients dubbed nutrient solution into the nursery pond, the depth of liquid to submerge the potato 1/3 is appropriate, using this method Not only has full nutrition, adequate water, no heating, disease-free infection, tube
