玉米是主要粮食作物之一,具有生育期短、适应性广、抗逆性强、成本低、产量高而稳定等特点,属于禾本科光合作物,并且它在农业生产中占有重要地位。其主要发育期分为播种、出苗、七叶、拔节、抽穗、开花、吐穗、灌浆、成熟等生育期。本文对玉米高产栽培技术、栽培气温条件以及影响玉米优质高产的灾害因素进行了分析探讨。
Corn is one of the main food crops and has the characteristics of short growth period, wide adaptability, strong resistance, low cost, high yield and stability. It belongs to gramineous photosynthesis and plays an important role in agricultural production. The main developmental period is divided into seeding, emergence, aesculata, jointing, heading, flowering, spit, grain filling, maturity and other growth stages. In this paper, high-yielding cultivation techniques of maize, cultivation temperature conditions and the disaster factors that affect the quality and high yield of maize were analyzed.
