粉垄栽培木薯增产效果及理论探讨

Production Increasing and Discussion in Theory of Smash-ridging Cultivate Cassava

为木薯等作物粉垄栽培提供依据,利用粉垄栽培技术种植木薯,与常规方法种植木薯相比较,探明2种栽培方法在根系、产量、品质等方面的区别。以‘华南205’、‘新选048’2个木薯品种为试验材料,在同一地点连续2年进行粉垄栽培和常规种植比较试验,在成熟期进行块根、产量、品质等调查测定。结果显示,木薯粉垄栽培比常规栽培单株结薯条数增加23.13%～39.10%,薯长增加6.94%～60.00%,薯径增加8.40%～13.91%,产量增加29.22%～63.78%;鲜薯淀粉含量增加3.23%～18.67%。表明粉垄栽培木薯可以提高产量,改善品质。并在此基础上进行以根系为主导的作物栽培的"根"本理论探讨。

Planted cassava by smash-ridging cultivation technology,compare with traditional cultivation,ascertain difference at roots,yield,quality and so on,provide the basis for the smash-ridging cultivation.The ＇ Huanan205 ＇ and ＇ Xinxuan048 ＇ of cassava verities as materials,at maturation period,smash-ridging cultivation and traditional cultivation comparative experiment at the same location for two years,investigate or measure roots,yield,quality and so on.The results showed that,compared with traditional cultivation,smash-ridging cultivation cassava could cause per plant roots rise 23.13%-39.10%,increased length of root from 6.94% to 60.00%,increased root diameter between 8.40% and 13.91%,the yield increased 29.22%-63.78%,and improved quality of fresh cassava,the starch increased 3.23%-18.67%.This paper showed that smash-ridging cultivation can increase the yield of cassava,and improve quality.And discussions ＂ roots as basic theory ＂ of crop cultivation which roots for leading.
