1974年秋,我区开始试验用红苕(甘薯)藤尖越冬作种,平均亩产鲜薯3,520斤,比同期栽插的苕块苗增产63%,具有省种、早栽、高产、有利于良种提纯复壮和防病等优点。1976年发展到近50万亩,去秋搞了50多万床。从两年来几十万床的实践看,抓好春管春繁是实现早产藤、多产藤,确保早栽密植,夺取红苕丰收的关键措施。凡是春管春繁搞得好的,到芒种时每根越冬苕尖平均产插条20多根,200根越冬苕尖产的苕藤就可栽1亩,而春管春繁搞得差的,每根越冬苕尖只能剪5—6根
In the autumn of 1974, our district began experimenting with winter rattan tips of sweet potato (sweet potato) for winter planting, with an average yield of 3,520 kg of fresh potato per mu, an increase of 63% over that of the planted seedlings planted in the same period with provincial species, early planting and high yield, Purification and rejuvenation and disease prevention and other advantages. Developed in 1976 to nearly 500000 acres, go to the fall of more than 500000 beds. Judging from the practice of hundreds of thousands of beds in the past two years, it is a key measure to ensure that spring pipe spring and spring are the means to realize premature birth and prolific rattan production, ensure early planting and close planting, and seize red bream harvest. Any spring tube spring well done, to the species of wintering each wintering tip average more than 20 root cuttings, 200 wintering tip tip of the rattan can planted 1 acre, and the spring tube spring made poor, every The root of the winter winder can only cut 5-6 root
