水稻半旱式栽培,是一种新的稻田栽培方法,其基本形式是把稻田改过去传统的平作栽培为一定规格的垄沟,以沟水持续浸润垄埂的灌溉方式种植水稻,改变了平田长期淹灌的水稻栽培方式,为水稻生长发育创造了优越的条件。本文通过两年的调查分析认为:半旱式栽培与平作栽培比较,半旱式栽培对水稻生长发育所表现的优越性主要有以下几个方面:(1)水稻的根系发达,发根力强,根的活力旺盛;(2)水稻的秧苗素质好;(3)能促进水稻分蘗早生快发,太分蘗多,分蘗的有效性高;(4)水稻的穗部性状好,产量高。
Semi-arid cultivation of rice is a new cultivation method of paddy field. Its basic form is to transform paddy field into a traditional flat-planting cultivation to a certain type of furrow, and to irrigate the ridge with continuous drench irrigation, to change the long-term Submerged rice cultivation methods for the growth and development of rice has created superior conditions. According to the investigation and analysis of two years, this paper argues that the superiority of semi-arid cultivation on the growth and development of rice has the following aspects: (1) The root system of rice is well developed and its hair root is strong , Root vigor; (2) rice seedlings good quality; (3) can promote early tillering of rice tillering too fast, too tiller, tillering high effectiveness; (4) rice panicle traits, high yield.
