筛选鉴定耐不良土壤水稻品种,对提高本省大面积酸、盐、缺磷、缺钾等中低产田的水稻产量有重要意义。1983年承担全省水稻育种协作攻关的水稻品种资源鉴定和国际水稻研究所耐酸耐盐的水稻品种筛选。 1983年采取室内和田间相结合,区试和示范相结合鉴定土壤酸、盐、缺磷、缺钾不良因素,室内鉴定611个,田间鉴定293个品种(系),合计904个,田间区试,示范面积152亩。初步结果:1、水稻品种资源耐低磷、低钾鉴定,
Screening and identification of poor tolerant soil rice varieties is of great significance to improve the yield of paddy rice in medium and low yield fields such as acid, salt, phosphorus deficiency and potassium deficiency in this province. In 1983 to undertake the province’s rice breeding collaboration in the identification of rice varieties and resources of the International Rice Research Institute of salt tolerance of rice varieties. In 1983, the combination of indoor and field test, field test and demonstration were used to identify the factors of soil acid, salt, phosphorus deficiency and potassium deficiency. 611 were identified indoors and 293 cultivars (lines) were identified in the field with a total of 904 fields. Demonstration area of 152 acres. Preliminary results: 1, rice varieties resistant to low phosphorus, low potassium identification,
