近年来,随着农村经济体制的改革,生产有了很大的发展。农民拥有种植的自主权,对优良品种颇感兴趣,勇跃兑换,积极购买。但某些农户所种品种单一,加之病虫害和恶劣气候条件的影响,致使产量大减。例如,今年陇东地区的某些田块小麦减产60～70％,其中宁县境内的大部分乡镇的农户种植中11—7小麦,由于其抗锈性的丧失和霜冻的为害,致使某些田块小麦籽粒秕瘦,产量大减、质量下降。另外,还有青麦4号、404、石中14等小麦品种均有不同程度的减产。然而,在庆阳地区的某些县乡大量推广的小麦新良种西峰16号,由于其中度
In recent years, with the reform of the rural economic system, production has greatly developed. Farmers have the autonomy of planting, are interested in fine varieties, courageous exchange, and actively buy. However, the single species of some farmers, coupled with pests and diseases and adverse weather conditions, resulting in a substantial reduction in output. For example, wheat production in some fields in eastern Gansu decreased by 60-70% this year. In most of the townships in Ningxian, 11-7% of wheat planted in rural areas was harvested due to the loss of rust resistance and frost damage, Pieces of lean wheat grain thin, greatly reduced yield, quality decline. In addition, there are green wheat 4, 404, 14 stone and other wheat varieties have different degrees of reduction. However, Xifeng 16, a new wheat variety widely popularized in some counties and towns in Qingyang Prefecture,
