我市水资源不足,传统种稻技术用水量大,扩大种植可行性有限。而且年际间受水的丰欠影响,种植面积极不稳定。水稻早种就是在这种情况下,依据当地的气候降雨条件和水稻苗期耐旱性较强的特点,采取不经过育苗插秧,把稻种直接播在墒情良好的土层内,靠吸收土壤底墒发芽、扎根、出苗与生长。以后再根据水源多少和土壤保水能力,因地制宜地采取水层灌溉,或主要靠雨
The lack of water resources in our city, the traditional water-based rice technology, expanding the feasibility of planting is limited. And during the inter-year due to the impact of abundant water, planting area is extremely unstable. In this case, rice is planted early in this case, according to the local climate and rainfall conditions and rice seedling drought characteristics of strong, without transplanting seedlings, the direct sowing of rice in soil moisture good soil, by absorbing soil At the end of moisture germination, rooting, emergence and growth. Later, according to how much water and soil water retention capacity, according to local conditions to take the water layer irrigation, or mainly rely on the rain
