种草养牛是缓解粮食压力的现代农业之路

Grass Growing and Cattle Raising as the Modern Agriculture Approach to Alleviating Grain Pressure

种草养牛是现代农业的必然选择。种草光合效率高,生物产量多,经济效益好,可以缓解粮食压力。种草形成的产业链比种谷物的产业链长,可以促使农民增产增收以及推动食品工业、轻工业和服务业的发展。种草的生态效益好:多年生,适应性强;空气固氮,改良土壤;节水耐旱,维护生态;保持水土,防止流失。饲料谷物与草有着同样优势。种草和饲料谷物使养牛业成为现代农业的主体。建议将"草粮并举"和"草粮轮作"确定为基本国策;改变对"草"的认识,大种其草,大养其牛,树立科学的整体食物观;学习借鉴西方国家种草养牛的经验,积极引进优良草种牛种;逐步把种谷物养猪为主的大量消费粮食的传统农业产业结构,改造为种草养牛为主的节省粮食的现代农业产业结构。

Grass growing and cattle raising is the inexorable choice for modern agriculture. High in photosynthetic efficiency, bio - production and economic benefit . grass growing can alleviate grain pressure. Growing grass forms a longer industry chain than growing grain, helping increase farmers＇ income and develop food industry, light industry and services industry. It also has good ecological benefit： it is perennial and adaptable, and conducive to air nitrogen fixation and soil amelioration, water - saving and ecological conservation, and soil and land conservation. Feed grains share similar advantages with grass, making cattle raising the backbone of modern agriculture. It is recommended to define as basic state policy ＂ developing grass and grain simuhaneously＂ and ＂ rotating grass and grain＂ . to transform perception of grass, growing grass and raising cattle energetically.and establishing an overall outlook on food, to learn from Western experience and actively introduce quality varieties of grass and cattle, and gradually transform traditional grain - consuming agriculture centering on grain growing and pig raising into modern grain - saving agriculture centering on grass growing and cattle raising.
