摘要
2003-2005年,在塑料大棚全程棚膜覆盖栽培形式下,比较了6月10日、6月20日、6月30日、7月10日、7月20日5个播种期对番茄单株成果穗数、单穗成果个数、单果质量、可采果株率4个产量形成因子的影响,从而确定番茄最佳播种期。结果表明,播种越早,最终可形成有效产量的平均单株成果穗数越多。育苗期使用旧膜覆盖会减少单株成果穗数;播种越晚,单穗成果个数越多,育苗期使用旧膜覆盖可增加单穗成果个数;相同品种以6月20日播种的单果质量最高,播种早于6月20日或晚于6月30日,单果质量均有明显下降;早于6月20日播种,可采果株数比例会大幅度下降;以6月30日播种的产量98 689.65 kg/hm2为最高,6月20日播种的产量95 395.20 kg/hm2次之,从而确定6月下旬为塑料大棚秋延迟番茄最佳播种期。
By comparing the effect of five seeding times,namely,June 10,June 20,June 30,July 10 and July 20 in the plastic big canopy,on average ear number per plant,average fruit number,average single fruit weight and the final fruited plant number,the best seeding time was determined.The result showed that the earlier the seeding time was,the more average ear number per plant was,and the ear number per plant would be decreased by using old plastic.The later the seeding time was,the more the average fruit number per ear was,and it would be increased by using old plastic in seedling stage.For same variety,the average single fruit weight was the highest seeded on June 20;the average single fruit weight reduced sharply sowed earlier than June 20 or later than June 30.If the seeding time was earlier than June 20,the rate of fruited plants would decrease greatly.The output of plants seeded on June 30 was the highest,namely 98689.65kg/ha,and the output of those seeded on June 20 was the second,namely 95395.20kg/ha,so the best seeding time was in late June.
