揭示作物器官建成的规律及其与环境条件的关系,是科学地运用栽培技术的理论基础。由于各地环境条件的差异,就产生了栽培技术的区域性与因地制宜的问题。尽管各地栽培经验不同,但如果提高到生物学基本规律上分析,就会发现其理论上的普遍性与地区间措施上特异点的辩证统一。在学习各各地经验时,经常遇到的问题是只有“经验”,但缺乏生态的、形态的和生理的指标,以致难以概括其共性并加以引用。即使
Reveal the law of crop organs and its relationship with environmental conditions, is the scientific basis for the use of cultivation techniques. Due to the differences in environmental conditions around, there has been a culture of cultivation of the regional and local conditions. Although cultivation experience varies from place to place, if we raise it to the basic laws of biology, we will find its theoretical universality and the dialectical unity of the specific points in interregional measures. Frequently encountered problems in learning from various localities are only “experience” but lack of ecological, morphological and physiological indicators that make it difficult to generalize and cite them. even if
