栽培技术对小麦产量的调节效应

摘要：小麦的产量不仅受品种遗传特性的影响，而且与生态环境和栽培措施有密切关系，科学实验研究结果表明：种植密度、播期、氮素运筹、灌水等栽培措施都对小麦的高产优质起着至关重要的作用，适宜的种植密度可以提高超高产小麦生育期间，增加光合产物的合成与积累，协调产量构成三因素，实现超高产：在小麦适播期范围内适当早播，能延长灌浆时间，有利于增加粒重，提高产量；而拔节期和孕穗期追氮能在保证足够穗数基础上，提高粒数和粒重，是实现产量突破的重要原因；灌水量和灌水时期对强筋小麦产量具有显著的调节效应。

Cultivation Techniques for Regulating Effect on Wheat Yield

Wheat production not only by the genetic characteristics of species, but also closely related to the ecological environment and cultivation measures. Scientific experiment results showed that： planting density, sowing date, nitrogen logistics, irrigation and other cultivation measures play a vital role on the high yield of wheat. Suitable planting density can improve the reproductive period of super high-yielding wheat, increase the synthesis and accumulation of photosynthetic products, coordination three factors of wheat yield and achieve super-high-yield, appropriate early seeding within suitable sowing date of wheat can extend the time for grouting, served to increase grain weight, increase production, The jointing stage and booting stage of nitrogen, ears can ensure an adequate basis to raise grains and grain weight, they achieve an important reason for realization of production exceeded, irrigation amount and irrigation periods of strong gluten wheat production has significant regulatory effects.
