对栽培草地进行田间管理的目的,是为了消除影响牧草生长的不利因素,为牧草繁茂生长和高产创造良好条件。(一)杂草的防除杂草是栽培草地最凶恶的“敌人”,它不仅与牧草争夺水分、养分及阳光,增加病虫危害,降低牧草产量和品质,还增加机械阻力,降低劳动生产率等。尤其是多年生牧草播种当年生长缓慢,危害更为严重,因此与杂草作斗争是建立人工草地成功与否的关键之一。杂草对栽培草地的危害,主要是由杂草的生物学特性决定,这些特性主要是:1.生活力特别强,适应各种生活环境,吸收力强,可以在牧草、作物不能生长
The purpose of field management of cultivated grasslands is to eliminate unfavorable factors that affect the growth of forage grass and create favorable conditions for the lush growth and high yield of forage grass. (I) Weed Control Weeds are the most vicious “enemy” of cultivated grassland. They not only compete with pasture for water, nutrients and sunshine, increase pests and diseases, reduce the yield and quality of pasture, but also increase mechanical resistance and reduce labor productivity. . Especially perennial grass planting slow growth, more serious harm, so weed fight is one of the keys to the success of artificial grassland. Weeds on cultivated grassland damage, mainly by the biological characteristics of weeds, these characteristics are: 1. Particularly strong viability, to adapt to various living environment, strong absorption, can be in the pasture, crops can not grow
