| 摘 要： | 本文整理和分析了免耕条件下小麦、玉米的生长情况,养分含量和产量结果。指出免耕条件下作物的生长发育、植株内养分含量以及最终产量都和常规耕作无明显差异,免耕加覆盖后,会推迟作物的生育期,作物生长前期氮素养分感到不足,而磷素和钾素可满足需要。随着作物的生长,差异逐渐消失,最后得到与常规耕作相等或更高的产量。

| Abstract: | Growth, nutritional status and yield of corn and wheat crops under no—till system were investigated. It was found that there was no significant difference between no—tillage and traditional cultivation in terms of the growth and the final yield of the crops. With straw mulches, the growing period of the crops in no—till system was extended. Phosphorus and potassium supplement met the demands of crop growth, but nitrogen was insufficient in the early growing stages. Later on, nitrogen deficiency gradually disappeared. Final yield of the crops in no—till system with straw mulches was equao reven higher than that with traditional tillage. |
