随着社会主义市场经济的深入发展,农作物种子市场竞争日趋激烈。为加快优良品种的选育、引进、开发和利用。各地都在筛选适宜本地区耕作制度、土壤条件和气候特点的丰产优质抗病的粮棉油等农作物新品种。笔者认为,大面积推广应用作物新品种,必须正确掌握以下原则: 1.坚持实事求是的科学态度,凡经确定推广应用的作物新品种,首先要有连续几年多点试验示范及大面积生产实践的结果,在历年的试验示范中,表现其丰产性较好,增产潜力大,穗、粒、重三者协调,品质佳,抗逆性强,成熟期适中,有利于作
With the deepening development of the socialist market economy, crop seed market is increasingly fiercely competitive. To speed up breeding of fine varieties, the introduction, development and utilization. All localities are screened suitable for the region farming system, soil conditions and climate characteristics of high yield and quality of grain and cotton oil and other new crop varieties. The author believes that a large area to promote the application of new varieties of crops, we must correctly grasp the following principles: 1. Adhere to the scientific attitude of seeking truth from facts, where identified to promote the application of new varieties of crops, we must first have a few years of trial and demonstration of a large number of large-scale production and practice The results show that in the past years of experimental demonstration, its high yield performance is good, large potential for yield increase, spike, grain, weight of three coordination, good quality, strong resistance, mature stage is conducive to
