利用粉垄机垂直旋磨粉碎土壤、自然成垄(厢),直接播种水稻。在旱种条件下,粉垄栽培的桂旱3号和培杂桂旱1号,其苗期根系长度比传统耕作对照(拖拉机旋耕深度18～20 cm)的根系分别增加61.77%、46.17%,差异显著,植株性状也相应表现良好。提出以“根”为本的作物栽培新理念,建议利用粉垄技术进行水稻的“旱播强根干湿交替”栽培和“水插(抛)秧干湿交替”栽培试验,以达到节水、保土、保肥、增产的目的。
The use of vertical milling ground powder ridge crushed soil, natural ridge (box), direct sowing of rice. Under dry cultivation conditions, the root length of the root system of Guanyan No.3 and Pei Guanyan No.1 increased by 61.77% and 46.17% respectively compared with that of the conventional tillage control (tractor tilling depth 18 ~ 20 cm) , Significant difference, the plant traits also performed well. Put forward the new concept of crop cultivation based on “root ”, suggested that the technology of “ridge-dry-wet alternation” and “dry-wet alternation” Test, in order to achieve water conservation, soil conservation, fertilizer, the purpose of increasing production.
