滇中高原玉米集雨抗旱高产栽培技术

High-yield Cultivation Techniques of Rain-harvesting and Drought-resistant Corn in Central Yunnan Plateau

玉米是楚雄州第一大粮食作物,种植面积在8.5×10^(4)hm^(2)左右,制约玉米高产的主要因素是水,为缓解这一矛盾,经过多年探索玉米抗旱高产栽培,集成滇中高原玉米集雨抗旱高产栽培技术。文章阐述了玉米集雨抗旱高产栽培技术的意义,并分别从玉米集雨抗旱高产栽培措施、田间管理、适时收获3个方面阐述集雨抗旱高产栽培技术。

Corn is the largest food crop in Chuxiong Prefecture,with a planting area of about 85,000 hm^(2).The main factor restricting the high yield of corn is water.In order to alleviate this contradiction,after years of exploring drought-resistant and high-yield corn cultivation,integrated corn rain harvesting on the Central Yunnan Plateau Drought-resistant and high-yield cultivation techniques.This paper expounds the significance of the high-yield and high-yield cultivation techniques of rain-harvesting and drought-resisting corn,and expounds the high-yielding and high-yielding cultivation techniques of rain-collecting and drought-resisting corn from three aspects:rain-collecting and drought-resisting high-yield cultivation measures,field management and timely harvesting.
