“自然农法”是遵循日本哲学家冈田茂吉先生倡导的“尊重和顺应大自然”、“充分发挥土壤的作用”的哲学思想,以保护自然生态环境、稳定提高农民收入和培育无公害农业产品的农作物栽培方法。自然农法应用于蔬菜育种及栽培中,能够培育出耐瘠薄(根系良好,能够充分利用地力)、抗病虫(抗胁迫,病虫害难以发生),具有绿肥的作用(还原的有机物多,地力消耗少)和良好的环境适应性(遗传多样性丰富,适应恶劣环境),可以自己采种(作为育种材料培育适合当地自然环境的品种),具有高品质(耐储藏、可口、高营养)等特点的品种,能够生产出真正无公害的蔬菜产品。实践证明,在优良栽培条件下虽能育出高产、优质、抗病的新品种,但育出的品种对不良环境很敏感,易受环境胁迫。应用不依赖化学农药和肥料的自然农法培育出 “Natural Agriculture Law ” is to follow the philosophical thinking of “respect and conform to nature” advocated by Japanese philosopher Okada Maugi and “give full play to the role of the soil ”, in order to protect the natural ecological environment and steadily improve the peasants Income and cultivation of pollution-free agricultural products crop cultivation methods. Natural farming method used in vegetable breeding and cultivation, can cultivate a barren (good roots, can make full use of force), resistance to pests and diseases (anti-stress, pests and diseases is difficult to occur), with the role of green manure (reduction of organic matter, Less) and good environmental adaptability (rich in genetic diversity and adapt to harsh environments), they can be planted by themselves (cultivate varieties suitable for local natural environment as breeding materials), and have high quality (storage-resistant, tasty and nutritious) Variety, to produce a real pollution-free vegetable products. Practice has proved that under the conditions of good cultivation can be bred high yield, high quality, disease resistance of new breeds, but breed varieties are very sensitive to the adverse environment, vulnerable to environmental stress. Application does not rely on chemical pesticides and fertilizers of natural farming method
