新疆耐盐丰产小麦新品系101、78特性研究

摘要

The new strains 101 and 78 of salt-tolerant wheat which have been bred by Fukang Eclolgy Station,ecolgical and geography institute in Xinjiang,Chinese Academy of Sciences,have the good characteristic of salt-tolerance,anti-lodging and higher yield.In saline fields,at 1.1% rate in salinity,a contrastive test have been produced,in which displayed that a yield of the new cultural strain 101 of salt-tolerant reached 7 180 kg/hm2 and 78 6 383 kg/hm2 . The two wheat which be planted in the soil of the moderate or high fertility,can reach the higher yield and suit the climate of north and south in Xinjiang.The two wheat have outstanding the breed benefit in production,in the soil of in slight or medium salinization;they are equal benefit than other higher yield wheat,in the oil of the moderate or high fertility.78 which belong to the property of the semi-winter,does not affect the yield in the late sowing at winter ago,is excellent wheat which follow the cotton stubble and the maize stubble.%耐盐丰产小麦新品系101和78，具有耐盐好、抗倒伏、产量高等特点。在盐分总量为1.1%的氯化物—硫酸盐轻度盐渍化地上，进行小区对比试验，耐盐新品系101产量达到7 189kg/hm2，78产量达到6 383 kg/hm2。这两种小麦在土壤肥力中等以上地块种植，可以达到更高的产量，适宜在南北疆冬麦区种植。在轻度—中度盐渍化地上，具有很高的品种生产效益；在中上等肥力的地上和其他丰产性品种相比，具有相当的效益。78属弱冬性，冬前晚播不影响产量，是接棉花茬、玉米茬的优良小麦品种。
