大寨式连队二十九四六连,大面积水稻高产稳产著称巴州。近年来,每年栽培面积三千余亩,年年过“长江”。一九七五年单产818斤,一九七六年860斤,一九七七年更达878.9斤。其中十五亩试验田,单产达到1,770斤,这个连的丰产经验是全面的,其中水层管理很有特色,现将我们的初步调查介绍于下。 水层管理是稻作的中心环节,随着全团性挖排治碱的进展,加上多年的种稻洗盐,土壤含盐量逐步下降,使得适应在重盐碱地区种稻的灌水技术,有必要也有可能发生变化。在这方面六连是勇于闯新路的。“深——浅——深——浅”的灌水原则基本未变,但深浅程度有了 Dazhai Company Twenty-four Liulian company, a large area of ​​high-yielding rice known as Pakistan. In recent years, the annual cultivation area of ​​more than 3,000 acres, over the “Yangtze River.” The yield was 818 kg in 1975, 860 kg in 1976 and 878.9 kg in 1977. Among them, fifteen acres of experimental field, yield reached 1,770 pounds, this even the rich experience is comprehensive, including aquifer management is very unique, now our initial investigation introduced below. Water management is the central part of paddy farming. With the progress of alkali treatment in the whole group, combined with years of salt washing and salt reduction, the soil salinity has been gradually reduced, making it suitable for the irrigation technology of paddy in heavy salinization areas. Necessary and possible changes. Sixth is the courage to break new ground in this regard. The principle of “deep-shallow-deep-shallow” irrigation has basically remained unchanged, but the degree of shading has been
