水稻旱植一是旱地套栽旱稻,二是望天田耐旱栽培。经多年生产实践现采取有水水栽,无水旱栽;有水水管,无水旱管;以及增窝增苗等配套技术,一般亩产可比同等水栽老秧增产50～75公斤,现将该技术介绍如下,供参考。一、适宜土质和旱稻品种布局。套作旱稻的土壤以壤土为好,其次是轻粘土及沙壤土,但地块都应靠近水源,土壤性质以偏酸的为好。在采取温室或地膜保温旱育秧的前提下,地处海拔高度850米以下选用岗优22、汕优63中迟熟杂交稻为好,850～900米选用汕优195、辐优63等中早熟杂交稻为主,900米以上以汕窄8号等早熟品种为好。

First, dry cultivation of paddy upland rice, dry cultivation of Wang Tian Tian. After years of production practice, hydroponics and drought-free plants are adopted; water pipes and drought-free pipes are provided; and other supporting technologies such as increasing seedlings and increasing seedlings are provided. Generally, the yield per mu is 50 to 75 kg higher than that of the same hydroponic plantlets The technology introduced below, for reference. First, suitable for soil and dry rice varieties layout. Soil for intercropping Upland rice is loamy soil, followed by light clay soil and sandy loam soil. However, the plots should be close to the water and the soil should be of partial acidity. Under the premise of greenhouse or plastic filming dry nursery seedlings, located at an altitude of 850 meters below the selection Gangyou 22, Shanyou 63 late hybrid rice is better, 850 ~ 900 m selection Shanyou 195, Radix 63 prematurity Hybrid rice-based, 900 meters above Shantou narrow No. 8 and other precocious varieties as well.
