为改变旱地粮食构成和提高旱地粮食产量,资中县龙结镇大路沟村经多年水稻旱地种植实践,总结出一套亩产400公斤水稻的旱地种植技术,其要点是: 一、选用良种,适时育秧。种植旱稻要选择适应性广、抗逆性强、根系发达、抗旱、耐旱能力较强的杂交水稻品种,如当前推广的汕优63、岗矮63等杂交稻种,均能在旱地种植发挥其生长优势,获得较高的产量。旱作移栽苗以长龄多蘖壮秧较易成活,一般地膜育苗比两段育秧的秧苗素质好,秧龄掌握在50天左右。具体下种日期可
In order to change the composition of dry land grain and increase the grain yield in dry land, Daliogou Village, Longji Town, Zizhong County, after years of practice of rice dry land cultivation, summed up a set of dry land planting techniques with 400 kg of rice per mu. The main points are as follows: Raising seedlings. To cultivate Upland rice, it is necessary to choose hybrid rice varieties with wide adaptability, strong resistance, developed root system, drought resistance and drought tolerance, such as the hybrid rice varieties Shanyou63 and Gang’ai63, which are currently popularized, can all be cultivated in drylands Its growth advantage, access to higher yields. Dry transplanting seedlings with long tillers stronger seedlings easier to survive, the general film nursery seedlings than two sections of seedlings of good quality, seedling age in about 50 days. The specific date can be
