在大安市盐碱地种稻首先要掌握好生育季节,适时播种、移栽,使水稻在8月3～5日安全抽穗,9月17～20日安全成熟。主推品种为抗盐碱性较强的藤系138等,其密度为3×8～6×9(寸),m~2穗数保证500～600穗左右。相关与偏相关分析表明,产量与m~2穗数、每穗总平均粒数均呈正相关,达极显著水平。盐碱地种稻应用有机肥或轻碱土来改良盐碱土壤,并且灌排系统要配套,田间渠道应为单灌单排,以便洗盐碱,每公顷施纯N150kg左右,适当配施P、K、Zn肥料,公顷单产争取获7500kg。
The planting of salt and alkali soil in Da’an City must first grasp the breeding season, timely sowing, transplanting, so that the heading date of August 3 to 5 is safe for heading rice, and it will be safe and mature from September 17 to September 20. The main push varieties are strong resistance to salt and alkaline Rattan 138, etc., the density of 3 × 8 ~ 6 × 9 (inch), m ~ 2 spike to ensure 500 ~ 600 spike. Correlation and partial correlation analysis showed that the yield and m ~ 2 spikelets, the average number of grains per panicle were positively correlated, reaching a significant level. Saline-alkali rice application of organic fertilizer or light alkaline soil to improve saline-alkali soil, irrigation and drainage system to be matched, the field channels should be single irrigation single row, in order to wash salt and alkali, apply nitrogen per hectare N150kg, with P, K, Zn fertilizer, hectare yield for 7500kg.
