旱稻学名叫陆稻,是高产的细粮作物之一,营养价值和水稻相同。但是它的根系发育比水稻的须根粗、长、多,须根上的根毛亦多,能深入土壤下层吸收水分,增强抗旱能力。在整个生育过程中,地面可以不要积水层,和种小麦等作物一样,每隔一段时间适时浇一次水,再把松土除草施肥等田间管理工作配合好,就能正常生长。如果和水稻一样在田间保持有一定水层,它也能适应。所以它和水稻相比,是具有既抗旱又不怕涝的双重特点,在我国华北平原和南方一些省的山坡有种植。 Upland rice is called Upland rice, which is one of the high-yielding fine grain crops with the same nutritional value as rice. However, its roots develop more than the fibrous roots of rice, grow more and have more root hairs on the roots, and can deeply penetrate into the soil to absorb moisture and enhance drought resistance. Throughout the reproductive process, the ground can not aquatic layer, and wheat and other crops, like a timely manner from time to time in a timely pouring water, and then weeding and other fields with soil management weeding, will be able to grow normally. It can also be adapted if it maintains a certain water layer in the field as rice does. So compared with rice, it has the double features of drought resistance and fear of waterlogging. It is planted on the slopes of North China Plain and some southern provinces.
