摘要
为了研究晚籼紫宝在不同栽培模式下的生产效益,特开展了人工手插、人工抛秧、机插、直播4种栽培模式的对比试验。结果表明:人工手插、人工抛秧、机插3种栽培模式的收获时期接近,全生育期相当,为121~122 d,比直播栽培的生育期约延长5~7 d;同时,与直播模式相比,人工手插、机插、人工抛秧的有效穗增加、每穗总粒数减少、结实率提高,株高明显降低;直播技术较传统人工手栽与现代抛秧、机插秧技术更省工节本,简便易行,其产量虽略低于人工手插、机插与人工抛秧,但生产成本大大降低,产投比较高,利润空间较大。
In order to study the production efficiency of Wanxianzibao under different cultivation modes, the comparative experiments of 4 kinds of cultivation models, manual transplanting, seedling throwing, machine transplanting and direct seedling were carried out. The results showed that the harvest time of 3 kinds of cultivation models, manual transplanting, seedling throwing and machine transplanting was close to the harvest period, the whole growth period was equivalent to 121-122 days, which was about 5-7 days longer than the growth period of direct seeding cultivation. At the same time, compared with the direct seeding model, the effective spike of manual transplanting, machine transplanting and seedling throwing raising, the number of grains per panicle decreased, seed setting rate increased, and plant height decreased significantly; the direct seeding technology is more convenient than the traditional manual transplanting and modern seedling throwing and machine transplanting technology. Although the production is slightly lower than the manual transplanting, machine transplanting and seedling throwing, the production cost is greatly reduced, the production and investment is high, and the profit space is large.
